the Amiga, it is necessary to show a wide diversity of languages for it. Some languages are particularly suited to individual needs, by using 'C' in most examples, it seems you are giving our a biased impression. In many cases a new user who wishes to program the Amiga will be better suited with a language other than 'C' Dear Mr. Castonguay, I just wanted to respond to your "Amazing Computing" article on Fracrual Fundamentals. l have Absoft's compiler version 1.3. I compiled your AmigaBASIC listing, the run time was cut down to just under 2 hrs 33 mins. Below is a picture of my computer set up. Amiga 1000 w/2.5 meg. I do not have a math chip or 68020/68030 cpu. I would recommend anyone that is comfortable with AmigaBASIC and does not want to take the time to learn another language get Absoft's compiler. I am looking forward to your next article on fractuals, hope this information is of some use.

Amazing Letters Dear AC: I read Mark Steffensen's letter in Amazing Computing 4.4 with interest, as his printer difficulty with Deluxe Print sounds like a problem I had with the original release of Deluxe Paint. 1 believe all that he needs to do is replace the “prinrer.device” file on his Deluxe Print disk with a copy of one from Workbench
1. 3 disk.
As long as I’m writing in, 1 thought I'd mention how much I enjoy this magazine, particularly the C and Assem- bly-Language programming articles. I found Creating a Shared Library and Guru Wisdom to be especially useful.
Keep up tire good work.
Sincerely, David Gross Ithaca, NY
- Thank you for taking the time to write.
MM Dear AC: Amiga X-10 control software was die last of tire three necessities I had to get before 1 could stop using my C-64 daily (the other 2 being word processor and planetarium simulator). My search for it ended when I saw the entry for Complications in Amazing Computing (V.3, 5,
p. 73). Their address is given as both 1727 and 727 parkview;
1727 is correct.
They were selling the X-10 CP290 interface and software for it, but when I wrote them in May 1988 drey were willing to sell just the software. I have no idea why drey’re not listed in Amazing’s Product Guide, just out. They have an ad in the April 1989 Amiga Transactor
(V. 2, l p.l6). The program is mostly mouse operated, but not
with a purely graphical interface. You click a text string
describing your waterbed heater rather dian an icon picturing
it, and you type in a string for the time rather than move a
slider. I found this a great relief in moving from the C-64
version, which was pure graphic but made me set event times
digit by digit with joystick and fire button.
There’s a rather more expensive program, Intruder Alert, listed in the InterComputlng ad in INFO (Mar Apr 1989, p. 74). It is listed as an alarm with X-10 control: I have no idea what it does.

Terminal in this issue. MM Dear AC: After waiting for
over four years, £ think it's time for launching a FLAME
aimed at Commodore and AC is die best magazine for airing
FLAME ON Let's face it Commodore, AmigaBASIC is die MOST frequently used language on the AMIGA computer line and we haven’t seen a decent upgrade to it since day one! Over the years the AMIGA'S inception, we (READ-YOUR CUSTOMERS) have seen some very nice hardware and system software upgrades coming from your talented engineers but we still haven't seen a decent upgrade to that “bow-bow” interpreter. For instance, we want:
a) The mysterious “NO END IF" error and all other bugs that
appear when developing LARGE applications to be SQUASHED. (I
know it’s not easy but at least TRY to make it bug free).
B) MUCH BETTER sound support.
Only a 256 byte sound buffer? Come on give us a break! How could you dare to limit us to 256 bytes with all that audio power under die hood (it's like hanging a carrot on a sdek in front of a horse).
C) Better animation performance. I know that since it is an
interpreter and not a compiler, you are constrained by what
you can do to provide faster, smoother scrolling and object
animation, but AT LEAST give us collision detection that
ACTUALLY WORKS predictably.
D) Mixed data type support. Let's have a TYPE-END TYPE data
record statement pair so we "lowly” BASIC programmers can
shorten the gap between C and BASIC.
E) Support for BINARY file type I O.
This is a must for any serious data manipulation programs.
D A SHELL statement so we can execute CL1 commands easily from within our programs.
G) Keyboard event trapping so we can painlessly incorporate
keyboard shortcuts into our programs.
H) A PIXELREAD function so we can determine what color is being
displayed and make decisions based on it.
I) A PALLETTE READ function so we can restore the user’s color
scheme on program exit.
J) Built in FONT support statements functions for opening and
changing fonts (another carrot in front of the horse type of
K) Finer text placement control down to Lite pixel level (not
just by line and column numbers).
1) Built in IFF eraphic load save routines- for OBVIOUS reasons.
1 can go on a bit longer but I think you get the message and this should be enough to keep you busy working for your customers for awhile. I have a strong feeling that a great deal of AMIGA users agree with me on most of the points above so let's get the ball rolling Commodore. SPEND a little money to SATISFY YOUR CUSTOMERS because that’s what business is all about-right?
Spend a little now and make a lot later.
Either have your own fine engineering people upgrade the code (I wonder if you even have any DEVELOPMENT SUPPORT staff assigned to AMIGA BASIC...?) Or pay Microsoft to do it-but just do it!
FLAMF. OFF In closing, I’d like to say a word to the third party BASIC compiler developers out there. You guys are light years behind your counterparts in big blue land (QUICKBASIC and TURBOBASIC both have fabulous integrated environments) so start catching up.

- Many of these demands’ can be accomplished through the use of
library calls or by using a third-party’s BASIC.
There is an AmigaBASIC command to read pixel color called POINT. Commodore does have many talented develope- ment supportpersonel, but not enough to do it all.
I have to agree that it is time Commodore worked out a deal with Microsoft to upgrade A migaBASIC. After all, it is the only language that is shipped with the Amiga, and should therefore put the power of the machine at owners fingertips. --MM Dear AC: Three cheers for your February 1989 issue! Not only did we witness the return of that most helpful column Bug Bytes, but for a change there are no reviews of games in Amazing Computing. Without denying the great allure of the Amiga as a game machine, there has been far too much attention paid to games by Amiga publications and software
The area I would like to see more growth in is educational and scientific software, which remains to be in pitifully short supply despite the hardware capabilities of the Amiga in those areas: there is to my knowledge not one commercial package that makes use of the Amiga's audio capability for music education or one that supports scientific plotting (i.e. log-linear graphs).
One suggestion for ait Amazing column: public domain programs and shareware. A question that may be of interest to many readers; are ARP and Conman still useful with the advent of Workbench 1.3?
Sincerely, Robert Y. Eng Redlands, CA
- Commodore is trying hard to implement many of the concepts
found useful in programs like Conman in VI .4. ARP will
essentially become part of the new ASL.Library in VI.4, see
“VI.4: A Prepreview" and “A New Attitude: DevCon SF ’89" in
this issue for more info. -
- MM Dear AC: 1 would like to congratulate you on a great
magazine, and make a few suggestions about your programming
I would like to see more articles that relate to programming the Amiga, but also I would like to see more variety in the languages used for examples. While ‘C language is the de-facto standard for Amiga programming, I am sure there are many people (like me) who dislike the style of ‘C’. Why not use different languages for y'our examples, there are many that have received bare notice. 1 think more attention should be paid to such languages as Compiled Basics, Assembler, Modula-2, Fortran, Forth, Draco, Lisp, Pascal etc. There is a multitude of programming examples in die public domain for the
new C* programmer, but these odier languages remain virtually ignored. In order to show off die versatility of the Amiga, it is necessary to show a wide diversity7 of languages for it. Some languages are particularly suited to individual needs, by using ‘C* in most examples, it seems you are giving out a biased impression. In many' cases a new user who wishes to program the Amiga will be better suited with a language other than ‘C’ Dear Mr. Castonguay, I just wanted to respond to your "Amazing Computing" article on Fractual Fundamentals. 1 have Absoft's compiler version 1.3. I compiled your
.AmigaBASIC listing, the run dme was cut down to just under 2 hrs 33 mins. Below is a picture of my computer set up A1000 w 2.5 meg. I do not have a math chip or 68020 68030 cpu. I would recommend anyone that is comfortable with AmigaBASIC and does not want to take the time to leam another language get Absoft's compiler. I am looking forward to your next article on fractuals, hope this informadon is of some use.

- AC wants to have as many articles on different languages as
possible. Because we rely on freelance authors there are
occasions when we may have a dty spell ora complete drought
concerning certain languages. In this issue there are articles
in AmigaBASIC, True BASIC, and C. In next months issue there
will be an article in Fortran, Fourth, C, AmigaBASIC, and we
will break new grounds with an introductory programming article
in APL. We tty to support as many languages as possible and we
appreciate your concern. MM Dear AC: John Steiner’s Super Bug
Bytes column in Amazing Computing, V4.2, described a
work-around that permits using Fast File System on the first
(user’s) partition of a hard disk. It involves Lise of the
public-domain program ASSIGNDEV. 1 tried this withoLit success,
receiving a message to the effect that “DHO; cannot be
removed,” (I used the later version of ASSIGNDEV, a
modification by Olaf Seibert, as found on Fred Fish Disk =111).
Remembering that the original .ASSIGN command can be used in the form ASSIGN name: to remove an assignment, 1 tried “ASSIGN DHO:” with each of the AmigaDOS 1.2 and the ARP 1.1 versions of ASSIGN, and the revised ASSIGN of AmigaDOS 1.3, but each time was informed that DHO: could not be removed. Then 1 tried the new form available in AmigaDOS 1.3: ASSIGN DHO: REMOVE and it worked!
All I had to do then was MOUNT DHO: (making sure that there was a mountlist entry for Fast File System), and 1 was able to use all hard disk partitions at high seed. In two weeks of use, I have encountered no side-effects, Sincerely, George W. Zopf Arroyo Seco, NM

10 Amazing Computing V4.8 ©1989 Amazing Reviews Superplan Spreadsheet and time manager for business use by Marion Deland Superplan is a new spreadsheet, time management, business graphics program from Grafox Ltd., a British subsidiary of Precision Software.
Precision deals primarily with PC- compatibles, and that’s where this program originated. Superplan is a powerful program designed for business use, but it is clearly a PC-style program (and a British PC program at that!) With a mouse menu interface tacked on top.
Intuitive Superplan is not, and it has some stiff competition in MaxiPlan, which has an excellent Amiga interface.
Superplan evolved from Logistix, also a PC port and one of die first spreadsheets for the Amiga. Logistix was praised for its power and condemned for its lack of an Amiga interface. With Superpian, Grafox has tried to add an Amiga interface (Phil Reynolds is credited widi the “Amiga conversion”), but they have not taken it far enough.
Precision emphasizes the time management aspect of Superplan, and at die moment it is die only program available in that category. If you are an experienced spreadsheet user in need of project time management, this may be the program for you. Odierwise, you will need to put in some study time. Don't expect Superpian to compare with Precision’s Superbase line for ease of use.
Frankly, 1 was disappointed. I had looked forward to reviewing Superpian because i had worked with the various versions of Superbase and found tiiem to be everydiing Amiga programs should be. I have also worked with a number of spreadsheets both Amiga and PC but Superpian made me feel like a novice.
Although I liked die program’s time project management aspects, I found the program frustrating to deal with and tiie manual useful only as a tutorial, not as a reference.
Using Superpian Wliiie I was waiting for my copy of Superpian to arrive, I made two lists: (1) What I expected from a spreadsheet program, and (2) What I expected from an Amiga program. Superpian meets most of the first list and almost none of die second.
Facts andjigures Protection: The copy of Superpian you buy is dongle-protected. As tiiey did widi Superbase, Precision offers a nonprotected version (encoded with your name) for S10.00 when you return die registration card. Precision expects to upgrade Superpian regularly, as they have done with Superbase. Although Precision is a young company in the
U. S., dieir customer support for Superbase dius far has been
good, and tiiis may be die key to success for Superpian.
Size: A Superpian worksheet is 2048 rows by 1024 columns, for a total of 2,097,152 ceils. Cell count is the same as Lotus 123, but much smaller dian MaxiPlan’s 8,388,608 cells. Recommended is 1 meg of memory; die “readme” file warns that the charts take a lot of memory.
Speed: Superpian is slow. I am not talking about benchmark comparisons of recalculation speeds, etc., which I did not do, but about the time it takes to enter data in cells and move around the sheet. Often I pressed return twice, diinking die first had not taken.
Startup: There are a variety of startup options: number of colors, interlace, custom screen, etc. The default mode is a custom screen widi 8 colors, but because the status area takes up 4 rows, 1 soon switched to interlace.
Worksheets are not saved with icons, so there is no option to click on the file icon and have it load Superpian.
Slash commands To use Superpian, you type “ ” for an alphabet of “slash" commands, some of which access another series of commands. This sounds like Lotus 123, but the commands are quite different.
When you first press you see an alphabet. You cursor through the letters to find what each one stands for. If you dick on letters with die mouse, they execute. (Doesn't Phil Reynolds know about “one click to select, double click to execute”?)
Superpian is a powerful program designed for business use, but it is clearly a PC-style program (and a British PC program at (bat!) With a mouse menu interface tacked on top.
This alphabet of slash commands sometimes seems a little forced. Critical path commands, for example, are accessed by “ k” (for Kritical). Graphs are accessed not by 7g”, but “ v" (View), Not intuitive, but you get used to it. All the expected spreadsheet manipulation commands are there, though sometimes the terms used are unexpected, like “Prefix” for the directory padi.
Time management Time and project management is where Superpian really becomes useful.
(I wish I had had Gantt charts when I was managing a corporate publications department!)
You create timesheets widi the Calendar commands, accessed witli u c".
A calendar can reflect time periods from half-hours to years (or non-standard time units using a look-up table), and a five, six, or seven-dav work week.
Creating a timesheet is fairly straightforward. The default start date is 1 1 84 (presumably, this dates from Logistix’ introduction), so the first step is to change this and other options. Next, you edit the calendar to change working hours or days. Next link die calendar to columns of the cument worksheet. The calendar is invisible on the worksheet until you enter commands. For example, DOMOY(COL) displays the day month year of the current column.
It becomes a timesheet when you assign rows to different people or equipment. A Gantt chart displays the timesheet graphically as labeled boxes.
PERT charts, which show the project as a network of intersecting padis, are not mentioned.
Critical parli analysis lets you see the shortest possible time the project can take, and the various jobs involved.
(Time functions in Superplan let you indicaLe die stan, end, order and lengdi of die jobs.) Example files help demonstrate this useful facility'.
Other spreadsheet functions Superplan has one difference in approach diat may prove confusing. With most spreadsheets, you select a range, then use a command like “copy”, “print", "graph”, etc. on that range. Superplan does it the other way round you select die command, then choose a single cell, a range or the entire worksheet. This is fine once you catch on, but it does not help with the learning curve. (By the ¦way, you cannot select a range by- dragging with the mouse, but you can click on die “corner" cells.)
Worksheets can be linked with the Vj” 0°in) command, “consolidating" or subtracting data from the worksheet in memory'. The example in the manual consolidates data from diree mondily worksheets to produce quarterly figures.
Superplan also includes database capability, and here it seems more straightforward than MaxiPlan. You simply lay out die records as a table, and use the Vt” (Table) commands to manipulate diem. You can sort, find and extract data, and load records from a dBase file. Database functions allow for statistical analysis of records: counting, averaging, etc. Programming Superplan was intended for use in custom applications. As with most spreadsheets, y'ou can write macros that control user access to die program. You can also rew-rite the drop-down menus.
A friend of mine who is a Lotus user suggests diat diis could be die reason for lack of a useful Amiga interface in Superplan. It may be that Grafox expected die macros to become the real interface, as diey often are in PC spreadsheets, especially in a business environment. From this viewpoint, the Amiga interface becomes a nice extra, but not really important. Whedier Amiga users agree remains to be seen.
There are two ways to create macros in Superplan. “Autos" are shortcuts for commonly used key sequences; they are defined quickly and easily. Superplan remembers y'our keystrokes, and you add commands for cursor movements, returns, prompt line messages, etc. Autos are loaded widi the program, and listed as menu options, with CTRL or ALT keystroke combinations. (No AiVIlGA keys, of course.)
“Macros” are more extensive. They arc written into the worksheet as a series of commands (a “macro language”), and offer more options, allowing you to automate a -worksheet. One command, for instance, allows you to protea your macro from accidental changes by die user. Another blanks the screen so you can hide the workings of the macro. A chart in the manual lists some Lotus SuperPlan macro equivalents.
A “Learn” option enters macros into the worksheet automatically, saving on typing and the risk of errors. This is a nice touch, available in several business- oriented spreadsheets. You can also Step through the macro invaluable for debugging!
You can run other autos macros from widiin an auto or macro, to build detailed applications. The manual includes a macro tutorial for building a mailing list in Superplan.
One point may confuse Lotus users, Macros are accessed by the Vx” (Execute) command, and options include “1" (Learn). Combined, die two mean something entirely different from die Lortis macro command 7x1”.
Superplan also has an Arexx port, so data can be passed to Superbase Professional 3. (ARexx itself is not supplied.) Por example, data can be passed to Superplan, where a graph can be created. Then the graph can be displayed in Superbase as an external graphics file. An example Arexx program is included.
Precision is putting a lot of emphasis on tire program’s Arexx comparability, but the truth is that Arexx, while it lias enormous potential for the Amiga, is not easy to learn. Will Superplan users want to leam another language to communicate with Superbase?
Charts Charts are not easy to set up in Superplan, but you do have a lot of flexibility. Those of us who are used to selecting a range graph type and having the program create the graph, as in MaxiPlan or even a PC spreadsheet like Quattro, have to put more thought into creating Superplan graphs.
Graph types include bar (6 types, with 3D option), pie, scatter, area, line step tick, spread, Gantt and text-only.
Each element axes, labels, titles, grids, frame, etc. is entered separately as a command in the worksheet. Each element can have its own font, size, color, hatching style, etc., and any individual segment of a pie chart can be “exploded".
There are limitations. For example, you cannot use your Workbench fonts, but Superplan provides ten fonts including several serif and sans serif typefaces, two scripts and an Old English style. Style commands for text can be entered in graphs but not, as far as I could tell, in regular worksheet cells.
To view graphs on die screen, you must run Superplan on a custom interlaced screen. In the default low-res, they are barely legible. This is probably why 1 meg of memory is recommended.
Printing 1 looked forward to printing out gorgeous full-color charts on my HI3 PaintJet. It was not that easy. Here's my sad story.
The “readme" file advised me to use Superplan’s printer drivers; my Amiga Preferences printer driver would simply give me a screendump. Fine. But there was no driver for any of my three printers HP PaintJet, Panasonic 1091 and Okimate 20, all common Amiga printers. Nevertheless, there were 12 Epson drivers, 9 NEC and 4 IBM! There are also drivers for plotters. How many Amiga users that you know use a plotter?
1 would settle for a Preferences version, but there was no information in the manual abouL Preferences; it’s not a PC concept. I had to search the interminable list of printer drivers by hitting the spacebar. I eventually found it under “Screen- dump", right at the end of die list.
Using Preferences did not help after all. Ali I got was a “printer initialisation error” (British spelling and ali). As a last resort, [ tried die “Dump” option to dump the graph to disk and print it separately. When I loaded the file into Butcher to print it, the graph was small, illegible, and the resolution did not match the original. It turns out that this option is really useful only in interlace, where it works fine. There is no information on this in die manual.
Next, I wanted to print out part of my worksheet (text). I looked in the manual to find out how to select a range, and began to struggle with die index. It took four attempts “Range", “Print”, “Output range”, and finally “Outputting to the IF YOU THOUGHT WE WERE HOT BEFORE, COME SEE US SIZZLE NOW!

using the default printer driver (which works for text, but
not for graphics), I got my printout.
The aiming interface Menu options act as autos, executing the slash commands for you. This has pros and cons. It is helpful to see the commands appear and execute. You get a feel for how the program works. On the other hand, it is painfully slow, and you have to keep track of where you are in the program. Several times I had to wait while die graph displayed twice, because I used die menu to save a Superplan worksheet ( SS) while I was still in die graph commands. (“S" displays a graph onscreen.)
Only one worksheet can be loaded at a time, and since the menu options ignore warnings, it is easy to wipe out your current worksheet by loading another from the menus. Amiga users expect multiple files; we do not expect a new file to wipe out die current one at least not widiout warning.
Superplan does not use die Clipboard to copy a range from one worksheet to another. To do diat, you make a note of the cell range, load in the new worksheet, and merge the cell range from the first worksheet stored on disk. Clumsy by Amiga standards.
Windows Some use is made of Amiga-style windows for the help screens and graphs, but they are not well thought out. The help window has a gadget that pops it to full screen size if you have made it smaller. Nice, but why doesn't die graph window have one too? The graph appears in the lower right comer by default.

The worksheet window can be resized, but only vertically.
This means that if you have loaded Superplan into a Workbench screen, which many people prefer, you cannot open a space at the right to get at the disk icons to multitask another program. (Did Phil Reynolds ever use an Amiga?)
There are no requesters. File directories and such are displayed in the worksheet area. If you want to open a worksheet from die keyboard, you type “ " for the slash menu, then type or select “z” to clear (zap) the current worksheet, “y” to confirm, followed by “ l" to load die new one and “s” for “Superplan file". Then you press F2 for the list of files, wait while the worksheet clears (slowly) and the list appears, then select the file you want.
Color Believe it or not, you cannot adjust colors within Superplan.
Superplan assumes you are working with PC colors (red, purple, light cyan, dark cyan, etc.), Your Workbench colors will replace the first four colors, though the program will continue to refer to them as black, white, cyan and orange. (Confusing?

Ground “white”, die border “red”, etc. This is one area where die mouse interface works. You can select color combinadons by clicking on them.
Help The manual and help screens vary very detailed and helpful on some subjects, and irritatingly vague on others, especially those that deal widi the Amiga. It is clear that this is the manual for the PC version of Superplan, with the addition of an Amiga introduction and a few insertions. (References to PAGE UP and PAGE DOWN keys, not available in the Amiga version, remain.) The mouse is mentioned at die beginning and thereafter ignored. Everything else, even the help screens, assumes you will be using the keyboard the PC keyboard.
The index does not contribute much. It was evidently created automatically with a word processor simply by listing all headkigs and subheadings. For instance, the single word “text” in die index refers to a minor point how to include text in an “if then” expression. I found what I needed on the second try, under “Entering text”. I could not find out how to copy a range from the index at all. And pie charts are not listed under “pie" or “charts", but “common pie charts”.
The help screens are more useful. They are context-sensitive.
For instance, if you ask for help while you are in die V (View) command, you will get a help screen on that subject. For the most part, help screens repeat information from die manual, but sometimes they provide more detail.
A “quick reference” card helps too, especially in explaining the menu of slash commands.
There are also extensive example files on a second disk- most of them very business-oriented. For example, one demonstrates a macro diat calculates and displays a “best fit” regression line. (Will many Amiga users need this kind of analysis?) Another evaluates an investment proposal, first in terms of a profit and loss projection, then as a detailed cashflow analysis. A more immediately useful file shows examples of die various graphs available.
Will Superplan meet your needs in a spreadsheet project management program? That depends on your needs. It would have a valid use in a business where a worksheet template is used over and over for various projects. Precision sees it as particularly useful for, say, a video production company with a number of clients and projects. But the time it takes to leam and set up will be too much for most of us.

Ago on a remote planet lived the Ancients, a group of intellectually inclined folks who enjoyed delving into collective thought worlds, dreaming of utopian-like existences where the could meet, relax, and drink tea (and possibly do their best William F. Buckley impressions). Eventually these thoughts became real, and 10,000 of these “perfect" islands, or archipelagos, were produced.
Then the ancients began to dream of a cloudy planet to the north. This place also became real, and one day its inhabitants came to die archipelagos.
The visitors liked arclilpelagos so much that they claimed die islands for their own by placing an obelisk on each island, and ridding the place of its inhabitants by draining the Ancients' blood into die soil (so much for non-violence).
Archipelagos shows an overhead (actually hovering) view of the checkerboard terrain that can be rotated 360 degrees. Your goal is to fulfill the last wish of the Ancients and clear the obelisks from the archipelogos. To do so, you must destroy the obelisks’ power source the standing stones by draining die stones of their energy. But before you can do this, you must connect the standing stones to the obelisks.
This may involve building a variety of complex structures, such as a vast landbridge from island to island. Odier obstacles include “corruptions” formed by the blood of the ancients, neuro- mancers (tainted bodies of the Ancients), and lost souls. The Ancients are obviously in rough shape, so make an Ancient’s day, cast a stone or two.

electronic in their quest to improve the reading skills of children. The latest in Hilton Android’s Robot Readers series has those gregarious Grizzlies and Goldilocks helping teach die youngins' to read using computer graphics and an electronically generated voice.
The Three Bears edition places the traditional story of the young towheaded lass who sabotages the home of the three mild-mannered bears in a format designed to introduce and improve children’s reading skills. While porridge flies, children learn early reading skills, vocabulary, and word recognition not to mention lessons in social behavior. The program is designed for use with litde or no adult supervision; all features are operable by mouse, with either control button initiating action.
Scenes from the story are displayed and accompanied by text. Each word in the text is highlighted as it is read aloud by the computer. Other features allow the child to select a specific word for entire word, syllable-by-syllable, or letter- by-letter pronunciation. The program also features a “find die word” game in which the computer voice asks the reader to find a word included in the text. When the task is successfully completed, the kids are awarded as the word is illuminated and a “beep” sounds, Also, by moving die pointer to a particular section of the illustration, the program will
identify the character or object.
The reading rate can be altered as well to suit the reader’s skill level. While die default rate is 125 w'ords per minute, the reading rate can be set for anywhere from 40 to 400 words per minute. The program runs on all Amigas with 512K required.

AllocMaster: Allocmaster is a memory control program. It allows
you to change tire amount of chip memory and other memory
available to the system by adjusting sliders for each. The
program then allocates the set amount of memory for itself.
This is a nice tool to help you test your programs in low

you can use to take a picture of memory before and after a
program runs. You can then assure that all memory being
allocated by a program is being returned when it is done.

MorelsBetter: These two hacks work with More.
One is called V: it’s a small “pure" CLI command that acts as a front end for More, causing it to create its own window. The other is Fenestrate, which alters the CON: window parameters inside More enabling it to, for instance, use ConMan features to create a borderless window on the topmost screen. Includes source. Author: Paul Kienitz, red Fish disk *-22 3 f, The Contents file on tire Fred Fish disk says "Amiga port of the former arcade game named Click", I don't remember ever seeing this game, but it did remind me of the arcade game Qix. The idea of the game is to capture 75% of the
screen by moving your player (one pixel) with the joystick.
Once you enclose a certian are of the screen it gets colored.
But beware of the enemy, There are two border patrols and two area patrols. The border patrols kill you if they run into you. The area patrols bounce around in whatever area you haven’t captured. They can kill you by hirting any part of your trail while you are capturing part of the screen. After each round both area and boarder patrols are increased by one and you start over with a blank screen, The only other way to die is by turning back on the line you draw while trying to capture part of the screen.
There is a high score screen, digitized sounds, start-up music, and some neat effects when you exit (ESC key). The digitized voice and instructions are both in German. I can’t read German (the game is pretty much self-explanatory), but it looks like tire game was written in assembly language. This is a fun game, and you can't beat the price (don’t forget: if you use the game, please remember dris game is shareware).
The contents file also says that "This version adds a "cheat” mode" which I didn't find. This is version II+, an update to the version released on Fred Fish disk -205. It has binary only and is shareware written by Oliver Wagner.

- =MM=- by R. Bradley Andrews Amazing Game Reviews SNAPSHOT Four
Amiga Game Reviews The future looks good for Amiga action game
fans. Many new conversions are on tire horizon, and most
promise to maintain the arcade standard for graphics and sound
. While most will require a full megabyte of memory, the cost
should be worth it. But now, on with die show.
Hostage Rescue Mission First on this month’s list is Hostage Rescue Mission. Originally developed by Infogrammes in Europe, it is distributed in the U.S. by Mindscape.
International terrorism is alive and well. Tire U.S. embassy has been stormed and its workers taken hostage.
You must lead an elite team of six commandoes in an attempt to secretly penetrate the building, free the hostages and bring the terrorists to justice.
You will start as a Lieutenant, but successful game play will let you advance to the Captain and Commander levels. As you would expect, at each level the missions are more difficult to add challenge to the game. Within a level, missions also vary in difficulty.
The harder the mission, tire less time your team has to successfully complete it. To simplify’ things, tire first scenario, Training, has no hostages so you can focus on fighting terrorists.
Game play is divided into two basic parts. The first involves placing sharpshooters at various locations around the embassy. They are so macho that they insist on moving into position while dodging the terrorists searchlight beams, so this process can become tense at times.
Traveling down the street can also be dangerous. Fortunately, the terrorists can only shoot what they see. By carefully avoiding the fixed pattern of the many searchlights, a skillful player can use dives and rolls to throw off the enemy’s aim. Team members can also dodge into windows and doorways for temporary protection from the probing beams.
Once all three marksmen have either moved into position or been slain by terrorist snipers, you can send in your three man assault team to storm tire embassy. The team begins on the roof, where they must rappel one by one down the side of the building, carefully timing their fall to smash through one of the windows and swing into tire building. Once the player is in the embassy, he must maneuver through the many rooms, shooting any terrorists encountered. Hostages must also be led, one at a time, to a safe room on tire third floor, from here they will be taken to safety.
During this stage, die player can quickly alternate between any of his available team members. The outside marksmen can be used to quickly scan lire windows to identify possible locations of terrorists or hostages. They can also shoot out the windows, aiming at any people inside. This is dangerous, though, since you can acddendy shoot a hostage or even a team member.
In the embassy, an overhead view of the current building level is displayed.
Lieutenant level show’s all people on die level, team members as red arrows, hostages as white dots, and terrorists as red dots. On the higher game levels these dots are only shown when you are in the same room.
While each team member is a skilled professional, none will act without your intervention. It would have been nice if die members -would at least defend themselves and guard any areas diey are facing. As it is, so much attention must be placed to each member that it is often good to just drop one member into die building and let him clean it out single-handedly. Bring in another member only if the first man is killed, or, if needed, to guard the hostage safe room.
While each level can be replayed as many times as desired, there is no key available to abort the current level and restart it. This feature is desirable, because losing even one man causes your mission to fail. Often. I had to kill off the remaining team members so I could retry die level and attempt to complete it without losing any men.
The graphics are well done and realistic. You can almost feel yourself hopping over the wall or ducking down the hah. The sounds are limited, but more than adequate. Some nice touches are included, terrorists scream as they are shot, and your vision blacks out if you are shot. The joystick is used for all control and is fairly effective, though it does take a bit of practice to get used to its use in the embassy section.
On die whole, Hostage Rescue Mission can be enjoyable. The basic game mechanics are easy to learn. The Lieutenant level is sufficiently easy that I performed well after only a short time.
But the higher levels should remain challenging. It is extremely frustrating to be blasted just as you walk in the room, but careful practice will almost make you an expert team leader. The limited theme does limit replay value, but on the whole the upper levels remain challenging and should please many game players.
Combat Course You have just been drafted, and off you go to boot camp and Midscape's Combat Course. Here, a wonderful drill instructor will mm you into a lean, mean, fighting machine. Your goal in training is to master die five different courses. The first three each cover one of the basic skills you will need. The Physical course tests your ability' to scale brick walls, crawl under barbed wire, and avoid guard dogs. Next comes die Risk course, with fewer obstacles, but more danger. You must lay dynamite and throw hand grenades, and die course is littered with land mines that can easily do
The final basic course is the Combat course. Here your hand-to-hand and rifle skills will be honed to smooth efficiency. The two final courses combine ail three skills in one intense experience. The combined course is die easier of the two and simply involves running the first three courses consecutively. The final is the Cobra Construction Set. This is an even more intense course with sufficient challenge and nonstop action to keep even die most skilled recruit humble.
Play in Combat Course is centered on the Options Screen. The bottom is an area that looks like the front panel of a VCR, with the top area used for visual feedback, including die actual running of die selected course. The reason for die similarity to a VCR is that many of its controls are used by the Instant Replay option, allowing the player to run through a video tape of the most recent course attempt. While not entirely necessary, it does add a nice feel to die game and can be useful in learning die course’s layout.
Another useful feature of the game is the inclusion of a Course Construction Set. Here a player can construct any course, tailoring the obstacles to his own particular desires. All die various types of obstructions are available and the only limit is the player’s imagination.
Other available options include the ability to change players names, view players scores, save load replays, save load courses, and save load high scores.
The last should really have been done automatically. A separate action should not be required to enable the saving or recalling of die high scorers. The joystick is used for all game control. While it Figure Tivo Fly the world's most powerful helicoptor to take your country's ground and skies Figure Tfjree Whip yourself into shape on the combat course works fairly well in most cases, the necessity to change between many modes during game play' can sometimes get confusing.
For example, when in fighting mode, moving die joystick causes various kicks or punches, and only by pressing die fire button will the player be sent back into movement mode and allowed to proceed. The designers did avoid using diagonals for separate actions, making control a little bit easier. The graphics compliment and game play are comparable with most other Amiga games, providing a good feel for the 011 screen action.
Part of die included manual contains a kind if induction speech from die drill instructor. The rest covers the various courses and game mechanics.
Combat Course is the kind of game that likely has a limited audience. While play is relatively smoodi and enjoyable, real challenge seems lacking. The play'er never truly dies, time simply runs out on the course. The theme just does not, in my opinion, hold as much gravity as blasting a real enemy in a real war.
Mind-RoU Next on the list is Mind-Roll, by Epyx. Similar in appearance to Marble Madness, this game features an eyeball which a player must guide in its quest to accomplish several predetermined quests in ten different dimensions. You can attempt diese planes or dimensions in any order, and players must accomplish a different set of tasks in each plane.
Once tasks are completed, an exit area becomes available which the player can roll onto in order to close die plane.
Tasks range from simply destroying all the obstructing blocks on the level by colliding with diem to finding all die keys hidden about the plane. Many times, certain objectives must be accomplished before others become possible. Sometimes collecting a key will open a corresponding door, allowing access to other sections of the plane.
The main opponent is time. A fixed amount of time is allowed to complete each level. While leftover time can be carried on to later planes, each subsequent plane allows less time to complete it, requiring more speed from the player.
Each level also features its own special obstacles. While some are invisible walls that can make negotiation of the board extremely difficult, most are visible and can be avoided with a little care. Obstacles include walls and pipes that block movement, death symbols that instantly kill off your eyeball, transporters that will instantly beam you to another spot on the plane, electric seas that will quickly drain away your life force, and platforms that can raise or lower the elevation of your eyeball.
The platforms can prove useful, enabkng your eye to sail right over other intervening obstructions.The joystick is used for all game controls and works fairly well. The graphics are well drawn and also add to the feel of the game.
The game falls short in two areas.
First, several planes are nearly impossible to complete. One contains a suction system that is activated if tire keys are picked up in the “wrong” order. The problem is diat there is no clue as to what correct order is. So tire suction usually kicks in early in tire game, eliminating any chance the player might have had to complete tire level. Plane One supposedly features a vertical run, followed by a drop to several subplanes.
But when attempted, a player’s entire life time is spent rolling up the screen, never reaching the path to tire sublevels, but simply dying as time runs out.
I may have missed something, but the sparse rules indicated no way to reach the subleveis and complete the plane. While there may be some way to complete this plane, putting it first in the sequence may discourage many players from trying die game any further. The other problem I have with the game is its occultic overtones. Many of the symbols in the game and opening screens features symbols that have an eerie similarity with Egyptian mythology that does not sit well with me. While this may not bother many people, it pervades the game and should be taken into account by potential purchasers.
Thunder Blade Next is Thunder Blade, by Sega.
Your enemies have surrounded the cities, infiltrated the forests, and filled the canyons. Flying the world’s most powerful combat helicopter, you must eliminate the enemy from the ground and skies of your country! Only then can you take the battle to the enemy himself and destroy his offshore base, forever ending the threat to your homeland.
An interesting mist in Thunder Blade is the use of both overhead and forward view perspectives. Some missions are flowm while looking down on the opposition, while others actually have your aircraft flying straight at die enemy. Both views have different benefits and drawbacks, and require slightly different skills to master.
Other than the perspective change, game play' is basically the same as that in most shoot-em-ups. The main idea is to maneuver quickly and shoot as fast as possible to destroy targets on your way to die final objective. The graphics are arcade quality, and they provide a nice backdrop for game play. While die joystick works reasonably well as die controller, it seems sluggish in some of the levels. Add to diis the seemingly unpredictable enemy fire, and die game can be extremely frustrating at times.
Often, it will seem you are flying safely, only' to suddenly be shot down by an aggressor appearing from nowhere.
At other times, so many shots approach that there is no way to avoid being destroyed. While Thunder Blade can be enjoyable at times, the awkwardness of its controls hinders its true value and I would recommend one of Sega’s other tides instead. This game is OK, but diere are better ones available.
Author’s Note On a closing note, I would like to respond to a sentiment I saw in a recent letter to die editor that may be shared by many readers. The writer alleged that game reviewers tvould never put down a game for fear of being cut off from receiving review copies of new' products.
While I cannot vouch for all reviewers, f am in no way afraid of alienating a games publisher. I try to call them as I see them, and I have had publishers angry with me on more than one occasion. Manufacturers may not like to receive a negative review, but diey generally realize that it will sometimes happen, especially if the game is not of the highest quality, I do, however, sometimes hype a game that when I look back several months later may' not have deserved it.
Why is this? As far as I can tell ,it is because I and other reviewers like games so much that we t:y to find the good in nearly every game that we play.
Thus, we can sometimes gloss over the rough edges because of our enjoyment of die game overall.
Tastes also differ between different play'ers: one player's favorite might be on die bottom of another's list. This focuses us on die need for a local computer store where die games can be tried before they are bought. While stores are not as cheap as some mail order operations, this hands on testing should easily pay for the cost difference if even one dud is avoided.

Derek J. Perry Amazing Game Reviews International Microdeal’s
International Soccer is a soccer game with great graphics and a
number of likeable playing options. The game is autoloading,
requires 512K, and can be played on all Amiga s (500’s-
2000’s). I don’t think I have come across a game with as many
You can play one to three players against the computer, or one-on-one, one-on-two, or two-on-two. Other options include team color choice, field conditions (wet or dry), wind (and direction) or no wind, formations choices, night or day games, and time per half an impressive list of options that are incorporated into the game very well.
Gameplay At the start of the game, you must choose the skill Level at which you want to play. The ball’s speed increases at different levels, with Level One being the slowest and Level Nine the fastest. The skill level also determines the quality of the computer team’s passing and defense. I started at Level One and was able to defeat the computer at least 50 percent of the time up to Level Five.
From then on, the computer’s team dominated play, scoring three or four goals to my one.
The game clock moves along at about three times normal rate of time.
During gameplay, you must press “T" on die keyboard to see the game clock. This will also display the score, half, and field conditions. I found this distressing especially in close games with time running out. Otherwise, the only time you see the time is after a goal is scored.
Soccer fashions Team uniforms can be chosen from a wide range of colors and shades. Not only do die players wear their colors on the field, but die fans in die stands show support for their team by wearing dieir teams’ colors. But there is no home-field advantage regarding the number of fans.
The fans are divided equally between the two teams, with half the fans wearing one team’s color and die other half wearing die other. Fans cheer equally loud for each goal that is scored. One last note on uniforms: While I liked the available colors, I would have liked die choice of striped uniforms. I was surprised that option was not available, since quite a few international soccer teams have striped uniforms.
Stra tegicformations The formation option allows you to choose your team's field formation. You can only choose the formation at the beginning of die game, so if you chose an offensive formation at die start and dien find you must play better defense, you are stuck. On several occasions 1 wanted to pause the game and change formations, but was unable to do so.
However, the option does allow for a few formations diat provide a medium between offense and defense.
Playing conditions The options controlling die field conditions are excellent. The wind option gives one team the wind advantage for half the game; the otiier team gets the advantage in die second half.
The wind speeds up or slows down the ball movement. You can also play a game under day or night conditions.
Under daylight, the players and ball do not cast shadows on the field; at night, the lights produce small, four-way shadows.
My favorite option is die wet or dry field option. On die dry field, players are sure-footed and never slip. On a wet field, sharp changes of direction cause a player to slip and loose control over die ball. But a wet field also causes defenders to slip, leaving the offensive player ¦ Left: A player attempts an ouer-the-head two-handed pass during a night game under normal conditions.

Unmollested. Visually, a dry field is well- groomed and even; a wet field has numerous puddles and a sloppy appearance. Play on a wet field is a little slower, but more challenging because players often slip. It would have been nice if the wet field actually deteriorated and became muddy, and if tire players’ uniforms became dirty as they slipped or attempted to tackle another player.
Maybe this will be added in die revised addition of die game.
On the field Players look and respond just as real players would. They fall when tackled, they inbound the ball with a two-handed, over-the-head pass, and die goalies dive to make saves at the net.
The only element of play that I found missing -was the players’ ability to head the ball. To kick the ball, press the fire button on die joystick. The longer you hold down the button, the harder the bail is kicked. After a few minutes of play, you will develop the touch needed for passing and shooting, At lower skill levels, it is easy for even first-time players to "weave Lheir way through die defense for a shot.
However, at higher skill levels you must pass to teammates more often. Passing is probably the hardest thing to do effectively. A perfect pass automatically gives the receiving player control of the ball. But on a missed pass you must change control of die players by pressing the fire button with the joystick in the centered positon, and chase die ball down before it is picked up by an opposing player or goes out of bounds.
If die ball goes out of bounds or a goal is scored, appropriate window's instantly appear on the screen. After a ball is kicked out of play, it can be put back into play in one of three ways: by an overhead pass on the sidelines, by a comer kick if the offense maintains possession, or by a goal kick if the defense controls possession on the base lines. A direct free kick is awarded for penalties. Tackling a player improperly will result in a penalty. .After a goal is scored, the team scored upon will receive a free kick at midfield to resume play.
The only problem I had with the program was in booting the system.
When I used the Minimegs two-meg memory expansion, the graphics would come up distorted, and when the options board tried to come up, Whammol, Mr. Guru would appear. I don't know exacdv why this happened, but when I rebooted without the expansion unit, the program ran fine. (The expansion unit worked well with other software.)
Since 1 am regularly active in athletics, sport games have long been my favorite type of computer game, and as long as the)- are accurate and fun to play, I am usually happy. Nonetheless, I always want more and expect more from sports games, International Soccer gave me what I expected, and left me wanting a little more. It is fun to play and has my recommendation. It Is a most for any lover of sport, especaillv a person with a background in soccer. I give it and Microdeal a high five!

Overview of MediaPhile 1.3 Getting Sta AMIGA iHmuftARI Amazing Video How-To Getting Started k fiat tfoa to Know by Richard Starr The good news is that desktop video is here, and your Amiga can be a big part of it. Recent developments in software and advancements in computer and video hardware give anyone the potential to be a George Lucas. If desktop publishing has democratized the printed word, then home video production has put the movies within everyone’s reach.
You already have a superb computer, capable of contributing to video production. An Amiga can function as a titler. It’s terrific for special effects, animation and all die other exciting new possibilities you’ve been reading about. You can put it to work in audio production, an application I’ve just begun to explore. It is almost essential as a tool for logging, scripting and record keeping.
You don’t absolutely need an Amiga to do desktop video, but it sure helps in lots of ways. You can, in fact, generate interesting video entirely on the Amiga, without benefit of a camera or editing facilities, so you don’t need to know much about video equipment.
All is not roses in home video. Desktop publishing really does come up with work as good as that done on professional hardware, but in video the same is not true.
The amateur-affordable formats, VHS, Beta and 8mm, with their upgraded equivalents, S-VHS, ED-Beta and Hi- Band 8mm, are nowhere near the standards required for broadcast. Amateur VCRs put up a pretty good picture, but next to a professional format machine anyone can see the difference.
Probably the most serious deficiency is the amount of picture quality lost when you copy amateur- format tapes. The best pro systems can still look pretty good after ten generations; ours are mud after three. For desktop producers, the first generation is the original footage, the second is the edited master, and die third is die distribution copy. So you see, we just make it in under the wire. Tilings are getting better quickly, but it will be years before you can produce a documentary' for Public Television at the desk in your den.
Above The studio of a desktop video gum Even with its technical limitations, 1 find that there is a strong and largely untapped market for creative small scale video production where real money can be made. I've done fund-raising videos for non-profit agencies in our community. 1 hope to be working on some pieces for use in local schools, funded, widi luck, by educational grants, There are organiza- in tions Uiat will distribute such videos if they are good, even though they were produced in non-professional formats. The key to making it work is quality production.
A guy like me is no threat to professional video producers.
Our local professionals must get about SI500 per minute of finished footage. They have even7 right to charge big bucks.
There is very expensive equipment to pay off, there’s studio overhead, and video is their full-time bread and butter. And, tlrey deliver an excellent product.
In contrast, my entire video ensemble cost less than one of their professional cameras. I work at it pan time, and 1 make my meat and potatoes elsewhere. Obviously, I can afford to work for far less than they must charge. My clients don't require video that meets broadcast standards. Usually, all they need is half a dozen copies to pass around to prospective donors, customers or classrooms. And there’s no way they could afford to pay the big time freight. That's why I’m not in competition with die fast lane professionals. I do work they would never get. Work that would otherwise not get done.
The acclaimed photographer, Ansel Adams, could have made superb pictures with a box camera. You can work to high professional standards, even within the limitations of today’s desktop equipment. Ail it takes is taste, imagination and good sense to produce work drat people will appreciate without reservation. If you do; they’ll be willing to pay for it.
I’ve learned that just as you don’t need to be a programmer to use your Amiga, you don’t need a heavy techie background to produce good video, but you need to know what you're doing. You need a guide to die tangle of nuts and bolts to know what equipment is required and to have a clear, accurate idea of how it works. I’ve had to learn the ropes in bits and pieces, because most sources of information, magazines or books, are either too technical or too elementary. In drese articles, I’ll try to give you the lay of the land in desktop video as I've learned it. Much of it will not relate to
the computer, but video is a large part of our Amiga’s considerable talent, Knowing just die computer isn't enough to get started. Here's the rest of the story.
Formats Deciding which video format to work with is like choosing among computers: Apple, IBM, or Amiga? In video, die best choice is less obvious.
There are many video formats available, but we're talking consumer not professional. That leaves us with VHS, Beta and 8mm. Beta and VHS both use the same half-inch wide tape, but diere are differences in the cassettes and the method of recording. Beta is said to put out marginally better quality than VHS, but it is almost defunct as a popular system, while plain vanilla VHS recorders are as common as refrigerators. 8mm, recorded on tape much narrower than VHS or Beta, is a minor part of the market, but gaining because 8mm camcorders are tiny and weigh next to nothing. There is editing
equipment available in each of the three basic standards.
Video Which format is best? My experience is with VI IS, but I haven't done side by side comparisons. Besides, to compare fairly, you'd need to use the absolute best equipment in each format, tuned to perfection. And then you’d need super technical equipment to find the real differences. I can only judge by what I’ve heard and read. As far as I can tell, the differences in actual quality among consumer formats are quibbles, especially when compared to professional equipment.
Comparing formats hv performance isn’t the answer.
All three formats have come out with enhanced versions, known as Super VTIS, ED Beta and 8mm Hi-Band. These are capable of producing horizontal resolution of better that 400 lines, compared to under 200 for the original systems and broadcast TV at 300. In fact, it's better than most consumer color cameras can manage.
In video, the numbers for horizontal resolution don’t mean the same as on computers. Television screens, like computer monitors, are not square. They are wider than they are high in a ratio of 1.33 to 1. TV folk want to make the figures for horizontal resolution represent the same degree of sharpness as those for vertical resolution. To do this, they count die number pixels in tlie length of a horizontal scan line equal to the height of the screen as though the screen were square.
Video resolution is actually measured by pointing a camera at a test pattern which has two identical fan shaped rasters, one horizontal, die other vertical. When you can barely see the lines in the fan, that’s the resolution. (There’s a lot more to it, but that’s the general picture.) Computer folk, on die other hand, need to keep track of frame proportions and memory requirements, so for them horizontal resolution is the full number of pixels their machines produce on a whole scan line, That is the big difference between video and computer resolution numbers.
So in terms of computer resolution, those new formats can put about 530 pixels across the screen 1400 x 1.331, while your living room tube is doing well at 400 1300 x 1.331. In comparison, the Amiga produces 640 in High Res and we consider that pretty' sharp. You can see that those new formats are actually quire good with respect to resolution.
Color is still recorded tire same old way, therefore color sharpness is still well below professional standards. But the super systems also do a better job of separating the ‘luma’ and ‘chroma1 segments of the video signal, which results in cleaner color and lets signals survive multigeneration copying. For desktop producers, that may be the most important advantage of all, Part of die trick is the use of a new recording tape which accepts higher frequencies, but this tape costs about four times more than grocery store video cassettes. Enhanced format camcorders cost around 25% more, and
editing systems for diem are currently too expensive for most people to consider.
Super Video Formats The ‘super’ formats are a genuine advance, but diey still suffer from die same amount of Time Base Error as their parent formats. TBE, visible as wiggly vertical lines in the picture, is die result of small speed variations of the mechanical parts of die video recorder. It’s the video equivalent wow and flutter in sound reproduction, and every VCR has it to some degree, even 2 inch professional models. Every time you copy a tape, new TBE is added atop the old, Time Base Error makes accurate The good news is that desktop video is here, and your Amiga can be a big pad of
it...If desktop publishing has democratized the printed word, then home video production has put the movies within everyone's reach.
Editing difficult and causes titles genlocked over such video to distort or flicker. Help is coming soon.
Consumer priced Time Base Correctors (TBCs) are about to hit the market and, using them with die super formats, home produced video may soon begin to approach minimal professional standards. It will increase the present standards for home production video. Home TBCs will also make true A B editing mixing the output from two VCRs available to desktop producers. We’ll be able to do dissolves and all kinds of other effects. To me, that's the most exciting news yet.
There is plenty of competitive volatility in the video game, so which format will win, and for how long will it reign, is a critical question when buying expensive tools. Most newly introduced electronic equipment comes down in price with public acceptance due to increased production. In a couple of years, beginners will probably find super formats affordable, but they will still be an expensive upgrade for part-timers like myself. We won't just have to replace our VCRs. To reap the full benefits of the format, most video processors, including genlocks, will eventually have to be replaced or
rebuilt (there- are several S-VHS compatible genlocks avaiable on the market).
That’s because, to simplify a bit, the new formats transmit the Figure Two Tape Path on a VHS Video Recorder Compatible with Dpaint Ilf animation... “If an Oscar were to be presented for Technical Excellence in Amiga Graphics, the winner would certainly be (the envelope, please) - The Director.. an exciting, unique program.. likely to become a classic.

Video signal over two wires, rather than one. More on drat later.
All the enhanced systems are downward compatible. For example, S-VHS machines will play and record VHS tapes but a VHS player goes out to lunch if fed capes recorded in S-VHS.
There is also VHS-C which is standard VHS in a smaller package, allowing for miniature camcorders. These tapes will run in a standard player with a special adapter. And then there's S- VHS-C. Confused yet? You can’t, however, play tapes recorded in one format in a machine of an entirely different format, Beta in a VHS machine, for example. The cassettes won’t even fit.
Video Compatibility Video systems are actually mucn more compatible among themselves than are computers. You have to stand on your head to bridge MS-DOS and AmigaDOS, but all American video systems can produce die same composite NTSC signal. (The PAL and Secam standards and their variants, used in other countries, are different but suffer little when converted properly.)
This is why 2 inch professional tape can be copied down to VHS and vice versa. Video processors, Amiga genlocks and frame grabbers will tvork with the signal put out by any NTSC machine, regardless of format. (The enhanced format machines put out single wire NTSC signals as well as the two wire ‘Y connector* signals, so those peripherals wall still work, but you loose some of the ‘S’ advantage). The point is, you can edit a master tape in a Super format or standard Beta or 8mm and, by connecting the machines together, make VHS copies for distribution, for everyone's grandmother to watch.
Revoln tio na ry Develop in ents On the horizon are a couple of developments that may revolutionize the field. One is pure digital video, in which all the picture values are recorded in binary code, sort of like a super high speed Amiga frame grabber. Aside from incredible quality and the ability to manipulate the picture like an RGB image on your computer screen, digital video will make generation loss extinct as the Studebaker. It is just now' becoming available to professionals.
The other development is the recordable compact disk, which could eventually make video tape, (as well as computer hard disks) obsolete. Tandy claims to have one almost ready for the audio and computer markets, A perfect medium for recording analog or digital video, the disk would make any frame instantly accessible, with no tedious tape winding. When? Probably not for years, but w’ho knows? For an amateur, spending big bucks on equipment that may soon be obsolete is always a risk.
Howr to decide? If you build onto equipment you already own, as I did. The choice of format is moot. If you’re starting from scratch, check out the features of the least expensive editing systems in each format before taking tire plunge. VHS is my default format and, luckily, there's a great editing system available, as we’ll see. Also, it’s the people’s choice and slightly cheaper.
Editing in Video Dump die garbage and put the goodies in the right order that's editing. You can't do good work without it.
Video editing is copying the picture and sound from one tape to another, so you need two VCRs: a player and a recorder. The heart of any system is the recording VCR. You may have heard die latest hype about how nice it is to have a flying erase head on your camcorder, but where you really need one is on your editing recorder. Flying erase heads make clean edits a sure thing. To understand why , it’s important to know' how' video is recorded on tape.
Edison discovered a century ago that recording analog sound is easy because the signal is simple enough to transmit along a string stretched between two tin cans. Today, you can record good sound or your Walkman, by slowdy dragging magnetic tape past a stationary recording head.
But it’s different with the very complex signal required for video. You need super fast tape speeds to record all that information; the earliest video recorders used huge reels for just a few' minutes of TV. On modern VCRs it’s done by recording a very narrow' magnetic track diagonally across a wide tape, rather than lengthwise along a long tape. That’s how you pack a huge amount of information at great speed in a very small space.
Look at the numbers: your Walkman audio cassette moves tape past the head at 1 7 8 inches per second and sounds great.
In VFIS video, the high speed mode (SP) is 1.31 ips, which is slower than an ordinary audio cassette. But the video heads zip past the tape at something like 170 times the linear speed of the tape, over 200 inches per second. That's how' the very' high video frequencies are packed onto magnetic tape, and on some machines, w'here the superb Hi-Fi sound comes from. It’s done by mounting the video and Hi-Fi audio recording heads on rotating drums.
Tlje Video Signal at Work Every video signal carries a control signal that your VCR uses to force its head drum to rotate exactly in s rnc with the picture information. The control signal is recorded along the edge of the tape, so that sync can be reestablished when die tape is played back. The control track also regulates the linear speed of the tape, to allow die heads to lay down evenly spaced diagonal tracks.
Because die tape speed is ‘servoed’ to the control track, two video machines will run at exacdy die same average speed even if not connected to each other. They are far more consistent than even die best non-servoed professional audio tape recorders. (Knowing diis, I’ve learned to use several VCRs in tandem for multitrack audio production in my videos.)
The other edge of the tape carries the linear audio track, recorded the same way as die sound on your Walkman, but at a lower speed. That’s right, it means that the video sound won’t be as good, unless you have a VCR with Hi-Fi audio, recorded at high speed along with the picture.
Certain 8mm machines even record sound digitally. But all VHS and Beta video recorders carry a linear sound track in addition to Hi-Fi. Some machines divide this track in two for stereo.
Interlaced Video A single video picture, or frame, is actually made up of two separate, interlaced images. We know that die Amiga is talented enough to produce an interlaced screen when we need it, which is one of the reasons it is so appropriate for video work. On the computer, an interlaced image seems to flicker because the sharp picture elements on each scan line arrive and depart thirty' times every second, which is too slow for eyes to interpret as a steady image.
But interlaced video was created to reduce apparent flicker. The eye blends flashing images into a smooth flow at about forty frames a second. Movies, which are shot at 24 fps, get around diis by projecting each individual image two or three times before moving on to the next one. Interlace does its trick by renewing the screen every 1 60 second instead of every 1 30 second.
Actually, only half die screen is being renewed that quickly but it’s good enough to convince our eyes. It’s not the top or bottom half that's renewed; it's every other scan line. The odd numbered scan lines are painted on the screen first, w'hile the even ones are blank. That’s video field A. Then these disappear and field B fills in the spaces, all within 1 30 second.
Unlike computer graphics, video images usually aren’t sharp enough for details to be unique to a single scan line and they’re usually moving around, so individual elements of the picture don’t seem to disappear unnaturally. That’s why the interlacing trick svorks fine for TV even if it is distracting on the computer. Each diagonal track on a tape is die recording of one video field, two tracks to a frame.
Recording Interlaced Video To record or read these various types of information on the tape, the VCR must have a separate head for each kind of track. Each head can both record and play back. There should be an audio head (writh its own private erase head) for sound, a head for control, and a pair of heads on die rotating drum, one Remember... Dedicated to the AMIGA Nothing but the best!

For each field. Some machines have additional heads on the drum for Hi-Fi sound and still-field playback. The drum makes one complete rotation for each hill frame of video, i.e. 30 turns per second, 900rpm, Most VHS camcorders have four video recording heads on a half size drum that rotates twice as fast.
Each head records half a field.
Adding it up How' does this all relate to editing? Edits in film are actual cuts, with the last frame of one scene literally glued to the first frame of the next. Video ’cuts' need to be as accurate and as clean as though they w'ere done on film; a full frame ending and the next one beginning, without garbage on the screen to distract the viewer. The picture mustn’t roll, tear, show noise or discoloration. In electronic imagery', this isn’t as easy' as taking scissors to celluloid.
Before recording a track, you should erase that section of tape to clean up any previously recorded material or noise.
Every VCR has a full erase head that u'ipes off everything across die width of the tape. Because tire video tracks are recorded diagonally, this head leaves a series of partially erased diagonal video tracks where it begins to work when you start recording.
The newly erased tape slowly makes its way over to the video record heads, a trip of a couple of inches on a VHS machine. That means die video heads must record over unerased tape for several seconds before reaching even partially erased video tracks and, finally, a fully cleared path.

Picture, in the form of shimmering, vertical rainbow stripes that dance across the screen and decrease in height as the old tracks pass by. (photo Shimmering rainbows, orange and blue appear over the woman’s left shoulder, a result of recording over unerased video) Most newer VCRs have features that allow' you to start a new recording over an old one, in sync (frame servoed) so die picture doesn’t usually break up or roll w'hen you play it back.

But it’s not bad.
What happens where you stop the new' recording before the end of the old one? You get a lengthy blank space in die control track after the end of the new' recording, as well as a section of erased video. (See Figure Three) When you play it back, it looks awful on the screen, as die head drum looks in desparation for a control signal, meanwhile reading garbage from the video portion of the tape.
Some machines get around this by not turning the erase head on at all w'hen you choose 'insert edit’ to record over old video. You get rainbows during the whole sequence, but no blank spaces. Then there are VCRs widi an ’insert’ feature that turns off the erase head a couple of seconds before allowing die tape to stop, so there’s no blank video and no blank in the control track. Instead of ugly noise at the end of die insert, you just get rainbows and the picture may roll a bit. This is better, but it’s not true insert editing, as we’ll see.
Some machines, especially camcorders and portable VCRs, offer a ‘back spaced edit’ feature which backs the tape to before the end of the last recording, and plays back a section of it, which you then get to see in die electronic viewfinder.
The new' recording begins just before the end of die old recording, That way die rainbows don’t last very long and diere’s no blank space in the control track.
Near Perfect VCR Editing Here’s a way you can get almost perfect edits on most consumer VCRs. After copying the first scene lo the recorder, you hit the pause button, instead of stop. The machine halts after recording a full frame, and is prepared to start the next full frame on tape it has already erased: no rainbows. You must leave the machine in record pause w'hile cuing up the beginning of die next scene on the player. Back up die player and run the scene by, releasing pause on die recorder a moment before the new' scene begins.
The problem is, you have to work fast or the recorder will aim itself off. That’s because when a machine is in pause, the head drum continues to rotate in one place on die tape: to keep from scraping a hole in the tape and avoid excess head w'ear.
Most VCRs automatically go from pause to stop after about 5 minutes.
If the machine drops out of RECORD even once during your session, your next edit will have a rainbow' and may roll a bit. If you want clean work you’ll have to start the whole production over again. It’s an awkward way to operate, especially for long work, but you can get quality' results. At least it can give you a taste of how exciting quality video editing can be. If your video production is generated entirely on the computer, this kind of editing may be all you’ll ever really need.
Just the Facts... WWWW is a phone book, bulletin board, address book, calendar, appointment book, autodialer, and alarm clock.
Fact: The key to practical editing is a machine with a ‘flying erase head’. IMounted right on the rotating drum, it clears a path just ahead of the video recording heads. As a result, diagonal tracks are erased diagonally, frame by frame (two fields at a time). All professional editing equipment is built around this feature. Most 8mm consumer decks have it now, and all S-VHS and ED-Beta equipment are so adorned. The only consumer-priced VH5 machine with a flying erase head is the Panasonic AG 1950. I’d guess that most of today's serious desktop video is produced on this machine.
The AG1950 is a full}' equiped consumer-type VCR with a tuner, tinier, wireless remote control and all usual the bells and whistles, including Hi-Fi sound. It also has most of the features that you would need on a full professional editing VCR. It has a jog and shuttle control that allows you to move die tape frame by frame or in slow or fast motion in either direction, for perfect cuing. Almost as important, it has a dead accurate, real-time counter (Hours-Minuies-Seconds) that works by counting pulses on the tape's control track. Of course, there's the flying erase head and the complex
electronics that go with it. In addition, two 1950s can be connected to a dedicated automatic editing controller to give you a competent VHS editing system costing less than S300Q.
Editing Modes With a flying erase head VCR and a decent playback machine, you can produce glitch-free video. You'd use the method I described above, but you can stop and restart the recording machine at any time without destroying the integrity of the tape. The problem is accurate editing. On an AG 1930, you can choose the exact place in tire master where your next VW V V prints out address labels, appointments, phone numbers, tilings to do, and a monthly calendar.

Scene will begin, but landing the correct frame from the original footage at that point is tough.
Here’s why: to record a new scene without any glitches, the recording VCR must synchronize itself perfectly to the control track of the playback machine. This is done by rewinding the player seven or eight seconds, then running die tape forward at normal speed. The recorder, waiting in record pause (or, in some cases, automatically rewround the same number of frames as die player, then run forward), reads the incoming signal and matches it. When the tape hits the right place, re- Figtire Three Ending a Recording Over Old Video Leaves a blank space in the video track as well as the audio and
control tracks R e c o r d i n q U v 0 r 0 I id V i d e id End Jia cording begins. Editing controllers, like the one available for the 1950, take care of all that for yon. Without one, you're on your own.
There are two recording modes in which an editing machine can operate and it is essential to understand the differences between them. In an assemble edit, the recording machine lays down a new control track as it records new video, the same as when you press RECORD. When insert editing, die recorder syncs itself and the incoming video to the control track that already exists on the master tape. Every editing machine, including die AG 1950, can do either kind of edit.
Assemble versus Insert Editing: Assemble edits normally replace die existing linear sound track with a new one.
The insert function replaces only the picture. However, it is possible to choose audio dub while insert editing to create a new linear sound track at the same time. There's an audio erase head positioned a fraction of an inch upstream of die linear audio head to allow accurate audio inserts with minimal overlap of old material.
The Hi Fi sound track, if your machine has that feature, is always replaced when you record a new picture, whether in assemble or insert mode. You may choose to turn the volume down to zero so no sound is recorded on that track, but the original Hi Fi track will still be erased. That means you can insert new sound on the Hi Fi tracks without disturbing the existing linear sound, then mix down the two tracks later. For example, you show a sports arena with crowd sounds. Over this you insert Joe Jock talking about die trophy. You can record his voice on the Hi Fi tracks, without intenupting
stadium noises (called ambience) on the linear tracks, (note: Hi-Fi sound is multiplexed into the video signal, therefore you must insert new video material when adding Hi-Fi sound.)
How do you use diese edit functions? If you are putting together a video on raw tape, you make assemble edits. You would let each scene run at least a few seconds longer dian where you plan to end it. That way, the next scene begins on already recorded tape, so die machine can make a clean transition.
Figure Four Editing VCR in Insert Mode The full erase bead is off, and the flying erase head erases two tracks (one video field) ahead of the video record heads. Audio and record heads are left alone INSERT MODE Editinq VCR i If you decide to go back and add a scene over already assembled sections, you’ll use the insert mode, since it leaves die existing control track undisturbed and, at its end. Neatly reenters the existing scene. Inserting a scene in assemble mode would leave a blank section in die control and video tracks tit the end of the scene, reflecting the blank space between the fu
11-tape erase head and the respective recording heads, just as when recording with a regular VCR. When assemble editing, the mess is covered over by recording the next scene.
Most video professionals fear that the patched together control track left by a series of assemble edits may not be perfecdy smooth, which risks instable playback. To avoid this, they put a control track on the tape before recording any scenes. This is called editing into the black. It’s done by recording a stable, unbroken video signal along as much of die of the tape you intend to use.
You can do this by leaving die lens cap on your camera and recording a tape with no image on it. Your machine must be in RECORD mode (which records video, control and sound, die same way Assemble Edit does) and set to the speed at which you intend to edit (which should always be high speed for best quality). Turn audio volume levels to zero so you don't record room noise from your camera microphone. Instead of black you can lay down color bars or a test pattern produced by your Amiga; any stable video signal will do.
When putting together the video, use only the ‘INSERT’ mode. If you forget and make even one assemble edit, the control track is broken and you'll have to continue with ‘assemble’ for die rest of the tape. Or you can lay down another non-stop control track in assemble mode, beginning before the end of the last assemble edit. Once this is done you can resume editing in insert mode.
A fringe benefit of editing into die black is that you can record any section of your sound track before the picture, which is necessary if images on the screen are to match narration or the rhythm of music. You can’t dub sound on a section of tape that has no control track, Most machines will just turn themselves off.
OK, so you can conveniently produce clean edited video using a flying erase head editing machine and a standard VCR.
Editing accuracy is still a problem, You need to release the recording machine from pause a moment before your playback scene begins because the recorder takes time to start up. On the AG 1950, die delay is more than two seconds.
Here's how I solved the problem. I have a Zenith portable VCR which, to my good fortune, can be set to run backwards at normal speed. By experiment I was able to come up with a stopwatch sequence that gives me reasonably accurate edits.
First 1 cue up the entry frame on the player and leave it in pause. The editing machine is cued to where the scene begins and set to insert pause or record pause (for assemble edits). I start die stopwatch and, at die same moment, punch the reverse play button on the Zenith. When the clock reaches ten seconds, I hit 'forward’ on the player, and at 17 seconds release the recorder. I zeroed in at 17 seconds experimentally, by counting the number of frames I overshot or undershot (30 frames per second) and making corrections.
To determine editing accuracy, define your target as the first frame before an edit on the source tape. If you get only that frame, then the next scene, you're right on. Refine this method by using footage of a dial-type stopwatch. My sequence takes into account all die odd things that happen in each operation, like startup delays, the time it takes to reverse die player, and my own ragged reflexes. I watched the fractional seconds on die timepiece and practiced. 1 could usually land in the original footage within three or four frames of die target. That's about as accurate as the automatic
editor I have now. Editing this way is tedious but it gives good results. You might comes up with a similar workaround for your equipment.
The editing controller (AG-A95) made by Panasonic to work with two AG 1950s, does all these kinds of things automatically. It puts most of the controls for bodi machines conveniendy on a single panel. It has a direct access system diat will wind the tape to a dialed-in timer setting within about three seconds accuracy, provided the timer was set to zero at die beginning of the tape. If you have put together an accurate log of your shooting footage, scene by scene according to counter location on a tape, this feature can save a huge amount of time.
Your Amiga is a big help for logging.
The controller can be set to Assemble, Insen or Audio Dub, and to combine Insert and Audio dub. It will remember the 'edit in’ points on source and master tapes and the edit out points on either one. Or you can start an edit and stop it manually when you like. The controller can also memorize and automatically perform a sequence of up to eight edits, but you begin to loose accuracy as the tape is wound back and forth.
Quality work requires precision editing, so it's a feature you might not find useful.
The AG 1950 is a wonderful machine, costing less than half as much as next cheapest professional VI IS editor. What is it missing? Not much. The biggest problem is lack of frame- accurate editing which is expected of professional machines as a matter of course. The AG-1950 system will come usually within three frames of the target on the source tape and often does better. This is close enough for most work but absolute precision is necessary' for some edits.
Since the machine is usually frame-accurate on die edited tape, you can usually try' again without rerecording the previous scene. Panasonic technical support said editing is more accurate from good quality' master tapes. Video recorded in camcorders are not considered as good as those filmed with a substantial portable VCR. I’ve had problems with camcorder tapes rolling when edited. A digital stabilizer, made to bust copy-protected tapes, has helped. It might also improve editing accuracy.
My other gripes concern the audio system. The AG 1950 has a terrific Hi-Fi sound system, but only monaural linear sound. Two track linear sound would not only simplify audio post production, it would make a channel available to record a SMPTE time code, or another indexing system that would make locating scenes easier.
Another problem is that the machine doesn’t provide separate outputs for linear and Hi-Fi stereo sound. You can choose either, and you can even mix them within the machine, but you can’t mix all three channels outboard. That's a real handicap for audio work. I’ve installed a separate linear output on one of my machines, but it’s risky to hack around inside an expensive VCR (buy' and Study the manual first.) And, sometimes you have to locate frames by audio, rather titan visual cues.
That’s why I’d dearly like to have a switch to disable the audio mute function, which turns off the sound when the machine is in ‘jog and search’. This amateur professional machine is an elegant and economical compromise. I’m grateful that an affordable system is available. If I wanted everything, I’d have to bite die bullet and spend the big bucks.
Buying my first AG 1950 was a big step. It was a yrear before I had enough work to justify purchasing a second one.
Once I had the editing controller, I felt I had arrived. Then came the Amiga, a genlock, and some sound equipment. George Lucas, look out!
In upcoming articles, we'll look at the video signal, setting up your desktop, signal processing, titling and special effects, editing procedure, audio production,and more. The Amiga is pan of it all.

Amazing Reviews Magni 4004 (je«iocl review by Oran J. Sands III I love the feel of a fine tool. Its heft, its balance, all the little tilings that make clear that this tool is designed for those who will appreciate die little details. Made properly, a good tool makes work a joy. The Magni 4004 is the genlock equivalent of a Snap-On box- end wrench a pleasure to hold and a privilege to work with.
The Magni 4004 does the usual genlock chores as well as any genlock, and better than most. But once you start using it, you will discover the depth of thought that produced it. The Magni 4004 genlock system simply approaches video from a different angle than most genlock manufacturers do. The people at Magni are video professionals making a professional video device, not computer- types attempting to wrangle video to do their bidding.
The Magni corporation designs and manufactures test and measurement equipment for the television industry', and nearly verey network relies on their expertise . By its very nature, test and measurement equipment must be more capable than the gear it intends to test.
Magni is one of the firms that defines the term “broadcast quality” for the rest of us, so it’s little wonder that they can design a "broadcast quality” genlock.
For those new to the desktop video scene, a genlock is a device for synchronizing the Amiga’s graphics with an external video signal and then allowing the two to be combined. The Magni unit doesn't stop there. It has more than one mode of genlocking, and it provides optional outputs as well. An optional remote control unit is available, as are diagrams allowing you to build your own custom remote control. The unit is controlled by hardware and software, not just hardware. But as any finely crafted tool should, it does its job and does it well.
The Magni 4004 genlock system is available for NTSC and PAL video systems. It is designed for use only with the Amiga 2000 computer, because it depends on signals found at the video slot that are not available at the RGB port. This is perhaps the biggest drawback to using the Magni genlock, because many of us started using the Amiga for video back during the A1000 era (and we’ll give them up when they pry' them from our cold, dead hands).
Newer Amiga video professionals however, seem to be snapping up 2000’s and 2500’s by the carload, so it really doesn't cramp Magni's sales.
If you’ve heard of the Magni but haven't seen it, that is because Magni has marketed it through its broadcast equipment distributors and publications. Its higher price is considered spare change by the video industry', so sales are brisk in that market. However, many Amiga dealers have begun carrying the Magni due to its reputation and customer demand.
The genlock consists of two printed circuit boards that plug into the video slot and one IBM expansion slot.
(The slot is located there to receive power and not data. It won't disturb Bridgeboarcl operation), These two boards, connected with two ribbon cables, have the remote control and video output connections poking out the rear of the 2000, The video signals are found on the 4 BNC connectors at the end of a “break-out" cable (supplied with the genlock) that attaches via a 9 pin connection. The remote control connects via a DB2 jack.
Installation is quite simple, just follow the manual. But before you plug everything in, READ THE MANUAL!! The Magni has several modes of operation that are preset at the factory-. Should you desire to use the genlock differently, you may need to reset these settings, and this could mean unplugging everything.
So please, save yourself some trouble and read the manual. You'll have a better understanding about where all the switches and jumpers are located if you can have the boards sitting next to you while you read die manual.
The manual is not die typical manual found with most computer equipment. That’s probably not a bad thing given that most computer manuals are a waste of a tree or two. But the manual does not give you example after example of how and when to use the genlock. It assumes you know why you bought it in the first place. It does, however, give you every little last bit of info about its technical operation and functions. Video professionals will recognize it as a standard video equipment manual, filled with schematic and wiring diagrams, photos and a troubleshooting guide.
Magni is used to getting calls from users about their equipment, but die calls are usually from Chief Engineers of networks and stations. They told me it was a bit of a surprise when they started to field questions from average computer users, whose knowledge of video was limited at best. They have since prepared several publications about different aspects of video diat may answer some questions that the manual doesn’t.
Many of those questions will be about the different modes of operation for the genlock. There are four methods of genlocking with the Magni and each is concerned with where the output signal gets its sync timing information.
Sync and Burst Lock This is the most desired mode.
The output video sync is referenced to die incoming video (if present). Output signal sync is not necessarily locked to burst (VCR) unless the incoming video is diat way (camera signal). The SC H phase (see sidebar) is the same as the input signal. Therefore, if the incoming signal is not present, the Amiga graphics are synchronized to the internal sync references (in which the sync and subcarrier are locked togedier). I would expect you to use diis mode about 90% of the time.
Burst Lock In this mode, die subcarrier of die output signal is locked to the input subcamer, but the sync is regenerated and re-synced to the subcarrier to produce the correct SC H phase whedier die incoming video was correcdy phased or not. This mode may be of great significance for users of editing systems diat need to maintain correct SC H phasing.
Sync Lock This is mainly for use when laying computer graphics over a monochrome signal which has no subcarrier to reference. The output sync Ls locked to the input signal's sync and the output subcarrier is then produced and referenced from die internal sync generator.
The output sync and subcarrier will therefore not be locked together. You probably won’t use this option often, but it’s nice to know you can mix color and monochrome signals (which can produce a tasty effect).
Interna I Reference The output signal's sync and subcarrier are locked to the internal reference and has the correct SC H phasing. Since no reference is made to the input video, any attempt to key or fade with that signal will produce great picture disturbance. Since this type of signal can lie produced by merely removing the input video when in the first mode, it probably will not be high on your list to use.
Special Effects The Magni offers several methods SC 11 refers to the phase relationships of the subcarricr signal to the horizontal sync. Although it takes a frame made of two fields to display a complete picture, it lakes two sucessive frames to comprise what is known as a color frame. This is because each frame consists of 525 lines of video, an odd number. The subcarrier to horizontal phase changes every other line therefore the phase of line one will lie different than the phase of line one of the next frame.
When editing two diferent sources of video together, it is important to not only edit during the vertical interval (between frames), we must also edit between color frames. If the SC H relationship is off, it will be harder for editing equipment to discern which frame to edit and the result may Ire a picture disturbance at the edit point.
Improper SC H phasing may occur due to maladjusted equipment, systems delays, mismatched terminations or as the result of a recorder output. Although somewhat esoteric, it has been proven to cause many of the otherwise unexplained editing problems we commonly encounter.
Oran Sands III of combining and manipulating the Amiga’s video and that of your source video. Like other genlocks, the Magni considers all pixels of color 0 (zero) to be transparent, allowing tire input video to be seen. The overall effect is that the Amiga graphics appear to be overlaid on the input video picture. The overlay can be faded in and out if desired. It is also possible to dissolve between the input video and tire Amiga graphics.
You can also change the overlay (or keying) from using pixels of color 0 to pLxels with a certain amount of luminance or brightness. You can also use the INVERT mode and reverse the keying effects, and make opaque areas transparent and vice versa (regardless of type of keying used).
External Key The external key input is used to determine what picture is shown w'hen.
Suppose your external key picture is a white image of a keyhole on a black background as the external key picture.

Many special effects units and editing systems now- interface with GPI capable devices to allow berter coordination of special effects during post production.
Software control You may also control die Magni’s effects and modes via software. Shipped with genlock are several disks, a demo by Magni (being redone when I reviewed it), a demo of Sherreff Systems Pro Video Plus (now Gold) and a disk with a program for controlling the genlock. Once started, this program will give you a half-size screen with sliders for setting levels and timing and a menu bar with puil-down menus for selecting modes of operation.
Having your control software covering yrour picture or animation is not desirable, so diere are hot-keys to push the program Into the background and to permit operation while it's hidden.
Here is one of die few problems you'll find with the Magni system.

After speaking with Magni about die conflict, 1 was assured dial this was being corrected, since I had the first version of the software. If this is cured then the software will be welcome at my place. The only other problem I experienced with the software was an annoying tendancy to need to give it several keypresses to start a feature. This seems to vary from machine to machine and also depends on die keyboard you have and what programs may also be running concurrently.
Another word of warning here.

Not because it was convenient, but because the slot allows access to the 4 bit digital signals the Amiga normally converts to the RGB analog signals other genlocks use. Magni determined that the Amiga’s RGB signals weren’t stable enough for them, so they use the orignal 4 bit data and perform their own Digitai-to-Analog conversion ensuring more stable color. They then transcode the RGB to Y, R-Y and B-Y signals (an interim step in producing the final composite video signal). At this point they can filter the separate components to reduce the
normal NTSC artifacts we would normally see disturbing the picture. Thus, they can ensure not only the best in Amiga video but also meet all braodcast standards.
The Magni 4004 genlock deserves to be considered tire genlock of choice for tire video professional who demands the best. Amateurs wishing to eventually use their video for more than home movies can’t go wrong picking the Magni. The only problems with the Magni are the software driver and the price. Throw away the former and save for the latter, it'll pay for itself soon altcrwards. ‘AC* Magni Systems, Inc. 9500 SW Gemini Drive Beaverton, OR 97005 Magni 4004 Genlock, S1695.00 | Inquiry 250 a I::::":::-:-:-:-;-;:-;:-'::-::'":...... : .....~Tr:::v:-c; by Oran J.

Reviews Sherejf Systems' Pro Video Gold I’ll never forget the day my local Amiga dealer called me and told me in an excited voice that he had a demo of die most wonderful program he’d ever seen. Two hours later, he arrived at my studio and we proceeded to watch the demo of JDK Images's CGI, marveling at graphic and text manipulation the likes of which we'd never imagined. That was 1986 and now 3 years later I’m once again awed by a demo of the same program now upgraded and transformed into Pro Video Gold.
If you never saw CGI you missed die first character generation emulator program for die Amiga. It allowed you to choose fonts, sizes and colors, and mix them as desired. After you created page after page of such text, CGI let you change diose pages creatively. Pro Video Gold does all that and so much more.
Pro Video Gold (PVG) is die latest in Shereff Systems' line of character generation software designed for the video professional. It offers the features a pro would want: color fonts, graphics, importable backgrounds, and most importandy, anti-aliased fonts.
Anti-Aliasing Anti-aliasing is the ability to reduce die "stairstepping" of slanted and curving edges of digitally created graphics.
(Figure 1 shows the letter A in both aliased and anti-aliased form.) Look from a distance and you’ll see diat the letter on the right looks smoother than die one on die left. Look even closer and you’ll notice that at each “stairstep” there is a pixel of color whose contrast is midway between die letter and the background.
The effect is to fool the eye into “smoothing" the jagged line. The resolution of the two images is the same, but die anti-aliased letter appears to have much higher resolution. So although Pro Video Gold operates in high res, it looks much better. While some programs using anti-aliasing have chosen to confuse everyone with huge claims of megaresolution, PVG advertises only its 720 x 480 Amiga resolution, but that doesnt mean it doesn't look as good as die others.
PVG now operates in overscan hires and accepts standard 16 color (or fewer) hi-res IFF flics as background graphics. However, those graphics need not be overscan size. Horizontal measurements may be 720, 704, 672 on down to 600 and the vertical specs may be 480 Anti-aliasing is the ability to reduce the “stairstepping” of slanted and curving edges of digitally created graphics.
Thru 400. Any pictures smaller than 720 x 480 will be centered within die display area.
Text Generation The most important features of a character generation program are its fonts. They must be very clean, nicely designed and optimized for the resolution used. Since few clean hi-res fonts have been designed over the years, Shereff Systems made their own and have righdy earned high praise for them.
PVG has four typestyles, each in four sizes, including graphics characters and often used symbols.
Typesty les: The number of typestyles used in television tiding is small. These usually include something resembling Helvetica and Times. PVG has its own versions of these fonts plus two odiers. There are 8 additional typestyles available at an additional cost.
At first glance, some might find this limiting, but let's see what diey can do.
You can enter on a line any font resident within the program, and use any of the 16 colors of the current paliette (chosen, of course, from the Amiga's 4096). Each letter may be a different color or size as desired. You may also choose die italics option to slant all the letters.
Color Fonts: PVG also offers multi-color fonts, similar to die Color- fonts you’ve seen. The advantage with PVG’s colorfonts is the ability to choose the multi-color option letter by letter for any of the resident fonts. Witii die multicolor option you have two choices, 2- color fonts or 4-color shaded fonts, The 2-color fonts are patterns such as cane, swirl, wave, metal and cobblestone.
Select both of the two colors from die current paliette. The 4-color option gives you letters that appear to be 3-D shaded or reflected surfaces. Choose these colors from die current paliette.
Anti-aliasing: The best font option is the anti-aliasing. You may turn on the anti-aliasing option and choose the color to use for die “mid-way” choice. Instead of doing special calcula ¦ tions to select where to place these pixels, PVG’s fonts have this information built-in. Turn on anti-aliasing and they suddenly appear. Because of the nature of die multi-color fonts, aliasing isn’t available when in multi-color mode.
You can design each page with any combination of lines, You can select 80, 64, 48 or 32 vertical lines in height for your fonts, as long as the page doesn't exceed 400 lines. You are not limited to using only that size of font however.
Options let you place a smaller letter on a larger text line. Letters may be put on the baseline or used as a subscript or superscript to create chemical and mathematical formulas. All text is within the normal 640 x 400 area which serves as the '‘safe tide" area. Since different televisions overscan at varying rates it is prudent to make sure your text will always be viewable.
An Amiga Program for Video Professionals Using PVG The most pleasing feature of this program is its ease of use. A video professional must not only have quality' but speed as well, Pro Video Gold uses the same user interface as CGI but refined and expanded. You access all program functions by selecting a function key (a novel idea, eh?) Which will result in a selection box appearing at the bottom of die screen (or at the top if it would obscure the current edited line ).
In this box. You make seiecdons using the cursor keys and the plus minus keys as necessary. Pressing the return key will complete your seiecdons for that line or letter. Pressing the “p" key in most boxes will select those choices for the page, from die down cursor position, I Figure One: Figure Two: A title generated in PVG Gold Tlje Letter "A" in aliased and anti-aliasedform Aliased Anti-Aliased (stair stepped) for time-saving global changes. If you select the wrong function, pressing the correct function key will immediately take you to diat function. There is no need to step backwards
through the selection menus to get to another function. The consistent use of these selection boxes and die selection function keys makes for faster learning and use of the program.
Another time-saver is the ability to copy a page to odier pages selections, text and all. If you are using identical pages where only the text changes, you are miles ahead of the game using the Page Duplicate feature. The Page Clear feature only affects the text from a page, leaving the selected features intact.
Pro Video Gold can create 100 pages of text at a time. Once created, pages may be saved to disk as a Job.
Jobs also load in from disk. The file name has no suffix, so it is difficult to distinguish between jobs or other files. I suggest that you tag each file with a job suffix or something similar.
You can't save 100 hi-res pages on a disk or place them in memory simultaneously. So each job is a description of the pages which are then "built" when they’re needed. With S meg of memory, die program can keep over 2500 pages in memory at one time.
Quick Backgrounds We've already mentioned using pictures as backgrounds, but they take up memory space. Using the Quick Background feature lets you use a background at no memory expense. The quick background is a ‘‘brush" taken from a current line of text or graphics and then "tiled” or "wallpapered” to create the finished background. Place your text over it as desired in the normal manner. This information is also kept when you save a job to disk. The graphics characters are also usable for quick backgrounds.
Options Most features are selected line byline and may be used in any combination. Features include shadowing, underlining, grids, and color backgrounds. Shadows make tire letter appear suspended above the background or ext aiding (called “fill”) from die pallette. Shadows can be any color and any size up to 10 pixels thick. Letters may be edged in any color from the pallete up to 10 pixels thick. Any combination of shadow and edge may be used as long as the final number of pixels doesn’t exceed 10.
Underlines or “accent” lines may be added to a line of text or graphics. The line may be any color from die pallete, and it may be under die letter, under but touching, diru the middle, at the top or above die letter as desired. Use the space bar to create lines without text.
Grids are composed of lines slanted, vertical, horizontal, or crossed which may vary in color and diickness. If adjacent lines have the same grid, the grids will line up for a continuous look.
Grids need not cover the entire screen, but can be small and placed where needed.
Backgrounds are selectable stripes of color that are one half of a line's width. You can color the top half, the bottom half, or bodi halves. They do not have to be die same color. Like grids, background sizes can vary.
It is not unusual to use all diese features togedier to accomplish the effect you want. As mendoned before, when selecting any of diese features, pressing “p” will preselect them for any remaining lines.
Display modes The difference between a character generation program and a text slide program is that the slide program needs a second program to display the pages of text and change between them. A character generator should be self- contained, allowing immediate use of die created page if necessary. PVG meets this criteria and exceeds it. Not only can you change between the pages, but the variety of transitions at your disposal is truely overwhelming.
Transitions range between simple changes like popping on die new page to digital-style effects like slides and page pulls, but PV Gold doesn’t stop there.
The digital-style transitions also include page flips and peels. It's quite difficult to describe the effects; diey need to be seen to be enjoyed. For that reason, Shereff Systems offers a two-disk demo set.
There are 99 separate transitions.
While many of them change or move the entire page at once, many of them will do the transition line-by-line. One transition is customizable; just select the line for transition and the time. A new “window” transition allows a preselected portion of the picture to change.
PVG groups die pages in groups of ten. Pages 00-09 comprise the first group and 90-99 makes up the last. To begin die display press the escape key. This makes the cursor disappear and fully displays any overscanned background.
To start a transition merely chose one of die following: Starting a Transition
1. Press the up down arrow key for the next previous page and
press the return key at the exact moment you want to change
2. Type in the number of the nex- page to be displayed and press
the return key at the exact moment for ihe change.
3. Press the function key for the group you wish to show. All ten
pages of thGt group will show, for a predetermined time
period, in numerical order.
4. Press the shifted function key for the group you wish to show
5. In global show mode, hit the help key for a showing of ail the
preselected pages of the entire group of 100, This is most
commonly used by cable systems using Pro Video Gold to display
messages on an unused cable channel.
If you don’t wish to include a page in any display group, exclude it by using the PASS transition. All group display modes will then ignore and bypass that page.
While a slow and lingering transition iooks pretty, it is little use to the video pro. Today's video requires a fast snappy change to maintain the pace of the production. PVG’s transitions are the fastest you’ll find. Speeds are variable on all transitions and may vary by page.
Dwell times are also selectable.
Tbe package Pro Video Gold comes packaged with a black, diree-ring bound manual and a keyboard overlay for the function key assignments. The manual itself is straightforward and includes a tutorial to help you leam the program. The appendices contain a lot of useful info.
The program itself comes 011 one non-copy-protected disk. (The program is copy-protected.) To begin, boot the disk and type PVP PROG (space) and the easy to remember serial number to start the action. The serial number is on Ibeloiv: Tbe many text options available in Pro Video Gold the registration card enclosed with the manual.
The manual includes instructions about using PVG from a hard drive. The 2090 hard drive controller problems with overscan programs are now legendary, and lo eliminate them PVG bypasses the problem by turning off all video DMA while using disk I O.
Memory requirements Pro Video Gold will multitask if the other tasks don't need to write to a Screen (i.e., they run in die background).
Because of PVG's memory requirements it’s unlikely that you'd be able to get it to work. Gold needs a ton of CHIP RAM and plenty of Fast RAM to work. It is possible to operate it in a lesser fashion with less memory. But trust me, get plenty to start with; you’ll be glad you did.
The program requires 445K CHIP RAM and 415K Fast RAM for non-aliased fonts. Aliased fonts require 90K more Fast RAM for a total of 505K. The 4-color shaded fonts need 3SK more, bringing the total of Fast Ram to 543K. For full function you'll need 1.5 meg of RAM total. If you wish to use background pics, you’ll need even more. On my 2.5M machine I've experienced no problems.
I have not mentioned the mouse because PVG doesn’t use it. In fact, it's recommended that you ditch it (for at least tire session). Intuition would slow down the program and eat memory.
Conclusions Pro Video Gold is one of the most professional programs you'll find for the Amiga. It performs flawlessly based on three-year-old, constantly refined code.
It’s quick, dean and easy to use, with high-quality graphics. No wonder that aldtough Shereff Systems markets almost exclusively to video people, its sales have often surpassed those of other programs whose ads grace even' Amiga magazine.
Although written for use as a character generation program, PVC also makes a fine business graphics program.
Most business graphics are text-oriented, and with PVG’s ability to save any screen as a IFF pic, it’s a natural for making text slides. PVG’s IFF files are unique as any anti-aliased letters retain their antialiasing after saving to disk. This is the key to making high-quality' slides.
PVG is one of the first Amiga programs for video professionals. Video hobbyists can use it to good effect titling weddings, home movies, and the odd birthday party or two, There's no reason your tapes shouldn’t look like the networks', Don't forget that PVC works perfecdy with any genlock for overlaying those titles, Would I recommend it? You bet! Invest in Pro Video Gold and you’ll never forget it.

297 .mazing Video Overview MediaPhile MediaProcessor An
editing system for the Amiga at an affordable price.
By Larry Krieff Welcome to another fine Amiga video product. At first glance, MediaPhile doesn’t look like much, but it does a lot for tire price. The MediaPhile 1.3 infarred contol unit costs $ 195, MediaPhile 1.3 MA s-port contoiler costs $ 99, and MediaProcessor software is $ 149. For those who use Superbase, the dongle is included in the hardware.
Memory to operate.) For video equipment I used a Sony EV-A80 for my source deck and a Panasonic AG-1830 editing deck for recording.
To get started, you must read the manual to install into your source deck a cable called the “sense cable". This cable feeds back information to the computer that gives you the counts or the hours, minutes, seconds, frame numbers so you can edit (or remove) the portions of die tape you don’t want to be For this review. I used an Amiga 2000 with a 20MB hard drive and 5MB RAM. (The program needs 1MB of Top The MediaPhile screen showing the Preferences menu and the current video deck configuration files.
Bottom The MediaPhile screen showing the start and ending edit points from the source tape.
Recorded to your copy. You must make two more connections to the Amiga one to tire second mouse port and the other to the left audio output. 1 have found only one problem with tlie.se connections: if you use your second mouse poit for Digi-Droid or Framegrab- ber, you will have to do some cable swapping.
Installing the program Installing the software to your hard drive is a snap. Open die program and double-click on the install devs icon and install libs icon and die program does the rest. Once this has finished, double-click on the icon that looks like a TV and the MediaProcessor program is enabled.
Inside the media screen you must go to the preference pull-down menu to see die names of the players and recorders you will use.
Now you are ready to learn the icons that determine what you want to do. These icons include power on off, eject, player recorder toggle, record, single frame step, slow play, X2 speed, play, rewind, fast forward, stop, and pause. Insen a tape into your player and rewind your tape using the icons described above. From this point on, use the icons on the computer screen to get your VCRs to do what you normally would do if you pushed buttons on the VCRs.
Setting up a Media-Base The next step is what makes the program unique among editing systems: it allows you to call up a "media base” of information by using "order files" to keep track of the editing starts and stops.
Use the order file to give each start and stopping point a name, an order number, and either the counts start and stop or the hours, minutes, seconds, and frame number.
Recording Animations to Tape with MediaReeorder-VS3D These “order files" can be placed in any numerical order way you choose.
For example, say you want something at the beginning of your copy, but it is currently the last thing on tape. Just change the “order number” to 1 and it will now go to that position on the tape first and then go back (or rewind tire tape) to the next starting point.
While shooting my own projects, I found that this feature is quite time efficient. On other editing equipment I have tried, you had to manually rewind the source tape, which meant you had to be near the machine at all times. Now I can edit a tape during the day and let the machines record at night. You can do all of the above using one tape as a source.
When I needed to use more than one tape as a source, I used tire same “media base" name and gave the second and third tapes new “order file names".
.411 of this works easy because of the pop-up menu to select from.
Fast and Accurate Based on my use of this editing system, I strongly recomend it for anyone who does a lot of dubbing. It is not only fast, but accurate as well. In the time I used the system, I dubbed numerous weddings, and used the seconds on the system to give me play time of exactly 30 second intervals of single pictures. One more helpful feature is being able to preview ever- thing before the final dub is made.
There are other fine features I did not get time to try on the system, like being able to transfer Sculpt-Animate's animation to video tape and the ability to take IFF pictures and put them to tape via. Die program.
The one problem I did encounter was that my Vidtech genlock did not let the program ntn correctly, 1 have been in contact with Dr. James Rickman, Jr. The president of Interactive Microsystems, By Michael Morrison Media Recorder-VS3D (MR) is a software package that works with the MediaPhile MediaProcessor and Aegis' VideoScape 3D (VS3D) to record animations frame by frame. To record frame by frame animations, you Will need MR software, the MediaPhile 1.3 Control Unit, and a VCR with flying erase heads.
Hotv It’s Done To begin recording, put your VCR in the record pause mode then doubleclick the MediaRecorder icon to get it running. Then start VideoScape 3D.
When your animation is ready to be generated, use a menu selection or keystroke to tell VideoScape 3D to start generating your animation. MediaRecorder will do the rest. Once a frame has been generated, VideoScape 3D will wait for a response from MediaRecorder: before continuing. MediaRecorder will tell the VCR to record the frame for about 1 second and then return to pause mode. When this happens, tire VCR will automatically backspace a few spaces.
(The ideal is about 2 frames, but this will vary depending on your VCR.) VS3D is signaled and it moves on to generate the next frame of the animation. This process continues until the entire animation has been generated and recorded.
Drawbacks The quality of your recordings will depend greatly on your VCR. Your VCR will need flying erase heads, and it will also need to backspace when put into pause record mode. The number of Inc. and he is looking into diis. If you encounter any problems while using die system, telephone support is excellent.

• AC* frames recorded for each frame of animation will again
depend on your VCR. This value can be anywhere from 10 frames
to about 2 frames. Any animations that you record will be
played back at a set rate according to this value. For example:
if your record time allows 6 frames to be recorded for every
frame of animation, the playback time of your animation on
video tape will be 10 framesy'second. Your animation will not
be able to play back on a VCR any faster.
Plusses By using MediaRecorder and VideoScape 3D, you can record a long animation that is limited only to the length of your video tape. One of the nice things about this method is that you can record without being there. Just start die VCR, VideoScape 3D, and MediaRecorder; then go to bed, have a snack, or walk the dog while they do their thing, MR allows a dean way to get your animations to tape. You don't have to have VS3D to record your animations to disk (although it is the easiest way). MR allows you to manually record a frame at a time. This means you could display and record each
frame of your animation one at a time. Xot the most efficient way to do it, but if you had to have it done it will work.
MR also comes with a small version called VS3D_Tiny. This program, run from the CLI, doesn’t open any windows and runs in the background. It is functionally the same as the larger version, but you can not interact w!idi the recording of the animation once it starts.

TITLtK review by R. Sbamms Mortier. PhD.
Graphic Designers work with alpha-numerics (letters and numbers) more than anything else. In fact, to be involved in the graphic arts at all, you must have a certain obsession with letters. When presented with a bundle of text, the graphic designer notices die ‘message" only secondarily. Truly, the medium becomes the message.
The shape, form and color of tire text takes on as much value, as much symbolic power, as the verbal content. In our society, this addiction to the visual is geometrically compounded, and reaches for its zenidi with die addition of movement (the first evolutionary seduction of die eye) in the videographic arts.
“Pure” graphics are like “pure” science. There is a danger of getting so caught up in die seducdve visualization of the world that the implications of die verbal content of the message can be overwhelmed. For proof just look at die graphically alluring posters and leaflets produced by demagogues the -world over, and the useless flurry of products in die marketplace all graphically advertised with remarkable expertise and craftsmanship.
No, the medium is not the only message we are responsible for as graphic and videographic designers.
Hopefully, we will be aware and responsible enough not to use the best means for the worst ends.
The medium helps Be that as it may, it is also a surety that the best intentions and the most necessary message can be w'asted and detracted from by less than professional treatment. That is -why even the smallest item cries out for the best design. Tiiat is why we go into debt to buy laser printers, color scanners, meticulous desktop publishing wares, and state-of- die-art character generators. That is why we lose sleep at die helms of our Amlgas, and that is why the technology keeps pushing ahead.
If the Wtong people are the only ones able to afford the means with which to shape the knowledge of the future into suitable form (which, in our era, means video-graphic form) then w'e’re all lost.
Probably the three items that are most worthy of attention in Broadcast Tiller are the number of colors that one screen can have when dumped to video, the effective resolution of the screen, and the importation of all Amiga- compatible fonts.
This is why the Amiga and other systems like it are so important. They are reasonably priced tools that allow democratic access to die information marketplace, spreading the capability to shape everyone’s message into a pleasing visual format. The advent of professional home video may be one of die strongest forces in assuring all of us die exposure to viewpoints and cridcisms from the widest possible sources, Now, to be certain, not every message needs all die glitter and pizzaz that computer graphics are more and more able to invest into it. A good story is a good story, and it can be dtled
with cardboard cards and crayons. But aside from die level of professionalism demanded by the videographic guilds, audiences on the brink of paying attention to a good story can be made to sit up straight if the form matches the level of design that has become the standard of acceptability. That’s just the way it is, period.
The best we can hope for (especially those of us who have unborn stories to tell, and animated dances to share) is diat die cost of the best tools will stay within our reach, and be developed and offered to die marketplace by able and caring creative people.
Tools for the task Enter die folks from InnoVision Technologies. I heard of Broadcast Titler about a year ago during one of my frequent calls to InnoVision, trying to uncover some new' information for my columns. I had previously purchased their “Video Effects 3D", and had filled up about forty' disks with tumbling, spinning and flying graphics. This program was so well designed and crafted that I wanted to be sure to remain in contact with InnoVision for any future wares diev might be dreaming of.
Up until diat time, I had never seen this kind of broadcast-qualitv generation on my' Amiga, not even on systems costing several thousand dollars. If you are not familiar with “Video Effects 3D” and think I am just offering unw'arranted praise, then check it out at your local dealer. “3D” remains a standard of Amiga software and professional videographics, So here it is, another InnoVision release. This one will indeed cause you to take leave of your socks. Like Video EFX-3D, Broadcast Tider is accompanied by a big classy binder that holds die manual. The manual is dearly written and amply
sprinkled with graphics. It also has a very' complete table of contents and a very useful index.
If you cannot understand the manual's terminology or run into Guru City, InnoVision has some of the best phone support in die business. I had one problem (which I’ll mention later) and got hold of them on a Saturday! As usual, they were quick to walk me through the possibilities.
The software is copy-protected by the "key disk" method, but the original program is only called up about every eight times you boot the software. Given the climate of ignorant piracy, I am in favor of protection schemes, though “key disk” protection makes me a little nervous. However, this “not-all-die-time" method is better than the constant requirement for die original copy.
Broadcast Tider sees Shereff System's Pro-Video Plus as its nearest competitor, so I have taken pains to compare both of them in an accompanying figure (I own and use both). I see no real competition for eidier of them, except from each odier, although a few other packages offer some similar capabilities (Martin Hash’s Animation Tider and Aegis’ Titier).
In their league, however, they really do stand alone. They also both operate via the Video Interrupt (the Amiga “Copper” chip), though Broadcast Tider pushes the Amiga's innards to unheard-of resolutions and performances. There seems to be a good-natured casting of the gaundet in the BT manual, as if daring Pro-Video to take the next upgraded shot. This is great two superprofessional Amiga developers challenging each odier for the prize. All Amiga videograpliic users are sure to win. As you can tell by the chart I have included, InnoVision is the undisputed leader at this juncture.
BT highlights Probably the three items that are most worthy of attention in Broadcast Titier are the number of colors that one screen can have when dumped to video, the effective resolution of die screen, and die importation of all Amiga-compatible fonts. These are die diree areas which Pro-Video will have to pay the most attention to when they burn die midnight oil.
Broadcast Tider can give you 320 Hi-Res colors per page, Virginia! That's right, 320 not the 16 colors that Hi-Res users are accustomed to. It can address 16 colors (a separate Hi-Res palette) per each line of text. There are controls that allow you to set die color ranges of each palette as you create the text. You can also SEE diese colors as you go, but if you save the work as an IFF file, you lose die multicolored vision. Better to save your work to video for your portfolio.
I do not pretend to understand the “Super Hi-Res” format the Broadcast Tider uses, except that it requires every bit and every corner of memory in the system. The programming task, as it addresses the hardware at die lowest Broadcast Titier can give you 320 Hi-Res colors per page.
That’s right, 320 not the 16 colors that Hi-Res users are accustomed to. It can address 16 colors (a separate Hi-Res palette) per each line of text.
Level, must have been intensive to say the least. The effective resolution of 2160 x 1440 can be alluded to, but it has to be seen to be appreciated. The real-time EFX will be mentioned, but only moving images do justice to their descriptions. I am not kidding when 1 say you will be astounded (excuse me I meant Amazed!).
As for the third capacity, isn’t this what we wanted all along the ability to reformat and use standard Amiga fonts?
Not that InnoVision will not offer its own fonts as well. It will. These are said to be of such high quality' that they will be totally antialia.sed (meaning no discernible jaggies). They will be constructed in a way that will all but remove die stairstepping ugliness of rounded and diagonal character attributes, and they will be available soon.
Meanwhile, take a look at all the lovely fonts sleeping in your Amiga libraries, especially die "ColorFonts" that most Amiga visualizers use by the bucket. Of all of these, die KARA fonts stand out as the most exemplary, and dtey look sharp and shiny in die Broadcast Titier environment.
All Amiga fonts must undergo a translation process to make them compatible with BT, but that's easily accessed from the first opening screen.
"ColorFonts" take more than four minutes a piece, but if you create a whole library of these fonts, you will have diem forever.
I spent the better part of an afternoon translating about twelve disks oi fonts. Most dedicated professional character generators (which cost about three to five times as much as this software) have only a set number of stored fonts. With this software, the Amigan has access to over two hundred Below IjflE Broadcast Tiller's 'Opening .’SK*' Screen" alpha-numeric symbols and there's more coming every day.
Obviously, this program (like most recent offerings at this end of the market) is hungry for RAM. It says it needs at least 1.5 megs, but don't be fooled. I was able to force it to crash after extensive fooling around, and I run
4. 5 megs. But believe me, I was able to stretch it way beyond
any normal boundaries with my expansion RAVI.
Hopefully, the price of RAVI chips will drop a bit in the near future. That would certainly help to sell more of diese packages.
Other features Character generators are known for making letters and words do all sorts of things in front of your eyes spins, turns, dribbles and many more choreographed movements. Like Pro-Video Plus, BT allows these movements to be generated by both lines of text on a page and by the whole page itself. BT allows for eight “line” effects, which are ways that lines are invited to enter and leave the page.
They include: Cut (sudden appearance), Teletype (typed one letter at a time), Slide (Sideways movement), Ease (acceleration deceleration), Wipe (screen pattered movement), Random Stripes (horizontal wiping pattern), Stripes (vertical stripes) and Cycle (palette changes for colors 2 thru 7). Effects can be timed as to speed and delay on screen.
The "EdgeMenu"for 1 adjusting"characteristics" The page effects are more numerous (70 full page transitions with 9 speeds each). Both Line and Page effects can be real-time previewed before assignment. It is very easy to set up the transitions, and it’s great fun to watch your work move on the screen. It’s so much fun that it is easy to get carried away, and make the novice’s mistake of doing too much at once. Remember, professional applications seldom require more than two or three different effects in any one sequence.
Both lines and pages can have backgrounds generated behind the text.
These backgrounds are as smooth and colorful as silk flags, and come in several choices and a multitude of palettes. You can also import any Hi-Res picture or brush as a background or as a standalone screen. Pictures should have the BT screen resolution in mind: 736 x 480.
This is the first really “borderless” Amiga screen on a character generator. Your artwork should be designed accordingly.
Now, back to that problem which forced me to call InnoVision. I tried loading some digitized 16-color images, and wound up with a screen, full of garbage. I checked with InnoVision, and it seems that BT has a problem with certain formats of digitized imagery. Pro- Video had no problem with these same images. InnoVision said thev were aware of the problem and that it would be redressed in a coming upgrade. I successfully loaded some Caligari backgrounds, however, as well as some of the previously saved BT pics.
Since no review is said to be complete without at least two complaints, I have another small gripe.
InnoVision should make sure that the “save" requesters list all previously saved material on the disk, so we can remember where we have named and where we are naming. It wouldn’t be a bad idea to also have a fill gadget to tell us the storage space remaining on a disk.
Well, that’s three ink blots, and even those will not stop me from raving long and loud about this product to eveiyone interested.
Oh yes, one last tidbit. Years ago, when 1 was just starting to feel die itch that would later develop into a full Vmiga compurer-graphics rash, I was mesmerized by another computer the fabled "Mindset”. I did everything I couid to attempt a purchase for the University of Vermont, but no go. Only now’ do I read in the BT manual that Jim Schneider, the head honcho of InnoVision Tech, designed the title and animation packages for the Mindset. What goes around comes around, and at last we re able to do fun business together.
Well I’ve got to stop writing now, because I’m in the midst of two short deadlined video productions in which Broadcast Titler will play an important part. See you in ROMulan space.

Melbourne House 1») 1T-' 7irWest'r Unit G9, Cc CA 92627-'(714) 631-1001 MELBOURNE HOUSE V1.4: A Pre-preview by Mike Morrison Let me start by stating the following: Commodore is working hard to implement as many of the following features as possible into Amiga operating system 1,4. Some are already done and many are being worked on at this very' moment. However, one cannot tell if alL of this list will make it into VI .4. as CbiM doesn’t know what kinds of problems may develop during this OS upgrade.
This list is the proposed list of new features; some of these may not make it into VI ,4. With all that said, lets move on.
The planned features list for the release vl.4 is substantial! Everyone I talked with at DevCon (See New Attitude- Devcon SF 89) seemed very impressed with the plans for Vl.4. Workbench 1.4 Workbench 1.4 underwent a dramatic transformation, not so much visually as functionally. Here is a run down: Select All Selects all the icons in the selected 'window. (Forget about holding dowm die shift key while clicking with the mouse.)
Drag Select Hold down the left mouse button and then move it. This forms a highlighted square, like those in a drawing program. When you release the mouse button, every icon that was within the square is highlighted.
Cancel Operation The right mouse button cancels what the left mouse button is doing. For example, if you are moving a tvindow' and still holding dowm the left mouse button, you can click the right mouse button to cancel the operation and return the window to its original location.
Workbench window- Workbench is now a window. It can be sized, dragged, and layered like all oilier windows. You can even use the new and improved cleanup (see below) on it.
View By You can now sort files by icon, name, or date. You can still drag them around like icons.
No Icons This allows you to display all files on a disk that do not have icons with a default icon. That’s right!
You can now access every file on a disk from Workbench whether it has an icon or not.
Patterns You can select a different backdrop pattern for both screens and windows. This helps you customize your own WB.
Title Bar The WB title bar now features a clock and displays of die amount of available CHIP RAM and other RAM.
Out of Gas The window fuel guage is gone. Each window shows the disk or drawer usage in the title bar. For a disk, the amount of free disk space available in K is shown. No more, "1 think it will fit”.
1. 4 Alpha 15, ho not redistribute Copyright 6 1985
Coiwodore-Aniga, Inc. All Rights Reserved This screen replaces
the hand holding the Workbench disk that comes up when you
fiistpower up, The disk moves back andforth from where it is
shown above into the drive until you put in a disk. The final
version will probably change.
The preliminary Vl.4 Workbench screen. Tire new option to show files without icons is shown.
The GUDU is dead. He died painlessly in the upgrade of the OS to V1.4. Multi-tasking You can click on the icon you want while a window is opening instead of waiting for all the icons to come up. Clicking on the close gadget while the icons are coming up and the window will close.
Quit WB This menu option sends WB away. You can re-run WB from tire CLI with the LoadWB command.
Reformat Disk: This is essentially the same as the ‘Format QUICK NOICONS’ CII command. It is used to re-format a disk that has already been formatted.
ResetWB This closes and reopens WB if possible. When WB reopens, it uses the current font, font color, and background pattern.
Error Info The DOS error numbers now have meaningful text strings displayed with them.
Window Arrows The window arrows have been redrawn and moved to the lower right of die window next to tire sizing gadget for convenient.
Icon Text Icon text and style is selectable from Preferences.
Startup Drawer Any icon in the startup drawer is executed when WB is loaded. This means if you purchase a program that needs to be run automatically, such, as a reminder program, you just drag the startup icon into the startup drawer. Nice!
Asynchronicity Rename and Info are now asynchronous. Refresh events are also asynchronous. Example: You double click on a disk icon. It first opens die window then adds the icons as it finds them. Before, if you moved or resized the window, some of the icons would disappear until disk access ended, when the icons would be redrawn. Now drey are redrawn as needed.
Icon file The icon file contains the location and imagery of each icon.
This means that icons are almost instantly displayed when a drawer is opened.
Arexx CBM has decided to implement Arexx, die high level macro language, as a standard part of the system software. 1 was going to try to briefly explain Arexx and dien I decided to let Bill Hawes do it, since he implemented Arexx on the Amiga.
"ARexx is a high level language specifically designedfor script processing and software integration. It is an implementation of Rexx (a language that enjoys an enthusiastic following in IBM mainframe environmentsj and thus provides compatibility with an emerging I It is difficult to grasp the ramifications of having Arexx at the fingertips of both developers and users.
Standard in mainframe and PC computing. Arexx provides both a system-wide scripting; language and a standardfor communications between software applications, and alloivs the end user an unprecedented opportunity to extend and customize their software.
Since its introduction on the Amiga in 1987, Arexx has grown in popularity with both end users and software developed. End users enjoy the flexibility of use and the open-ended design of Arexx compatible software, and developers appreciate the extra functionality that Arexx brings to their applications at a minimal extra cost in development time.
To date, over two dozen software packages have provided support for Arexx.1' It is difficult to grasp the ramifications of having Arexx at the fingertips of bodi developers and users. This is another example of the Amiga leading die way. Odier home computers don't have anything similar to Arexx, or if they do, it isn’t widely used or distributed.
ASL Library The ASL.library is a collection of commonly used Amiga routines such as requesters, file requesters, sorting, random numbers, and possibly a color palette. This will help different programs look similar so die user gets used to a familiar interface. This will also reduce the overhead of a programmers code.
Most of these rouunes will seem somewhat familiar to most people.
Charlie Heath is working with CBM on diese routines. Charlie has worked hard to improve the Amiga. Some of diis work has been done free because Charlie wants to bring the power of the Amiga to the users. It’s nice to see that all his hard work is starting to pay off.
Enhanced Chip Set (ECS) The ECS consist of the 1 meg Agnus chip (8372-R3) and the new Denise chip (8373-R2a). The chips are plug compatible with all models of the Amiga, except, unfortunately, the A1000.
The new Agnus chip supports 1 meg of CHIP RAM, as most everyone knows by now. It also supports rectangular blits up to 32k by 32k! The new Agnus chip is now available at your local Amiga dealer nowc The new Denise chip will provide SuperHires mode, Productivity mode, and four Genlock capabilities.
SuperHires mode (35 nanoseconds pixels vs the old pixels at 70 ns) will support up to 1280 horizontal pixels per scanline on a standard NTSC or PAL display. All of the old modes are still supported.

Productivity mode will allow 640 x 480 non-interlaced screens with up to four colors on a multi-sync monitor.
CAD CAM and desktop publishing are two applications that come to mind as taking advantage of this mode.
Genlock The new Denise chip allows four genlock modes.
CliromaKey allows any color register to control the video overlay.
BitpianeKey allows any bitplane to enable video overlay.
BorderBlank creates a transparent “frame" surrounding the active area of the screen.
BorderNotTransparent makes an opaque ‘frame” surrounding the active area of the screen.
The Denise chip will be available with the release of V 1.4, with no date given for either. After speaking with many developers and CbiM employees, the general consensus is “possibly before Christmas".
General Improvements There are many improvements scheduled for V 1.4 that I didn’t talk about above, and here they are.
EIW: This device now handles notification. This notifies a program if a file has been accessed (i.e., copied, moved, appended, etc). The new Preferences will use this to know when to update system information after a user modifies it.
File System: Fast file system is now in ROM and supports both the ‘old’ AmigaDOS files as well as FastFileSys- tem files. This will allow FF to work with floppies! DOS will support record locking, which is useful for networking (as well as multitasking) enviroments.
Exec: General performance improvements and fine tuning. Exec checks memory and ROM before using it, and checks for a 68030 68882 and enables instruction burst. Preparation for Virtual Memory support in a future version of tire OS have been added to Exec. Exec was already pretty stable in V 1.3, and therefore didn’t need much work.
Graphics: In addition to the features listed above, there will be support for different resolution monitors as well as different scan rates. The Zorro II Prototyping Board

A2024 monitor has built in support. Text speed has been improved and color fonts will be supported. Scalable (outline) fonts will probably come after die release of VI.4. Intuition: Screens will support auto scrolling for areas larger than the viewport. There are now custom gadgets and a new string gadget. These gadgets are easy to cusomize, such as custom editing for string gadgets. There is also a new EZRequester which is an enhancement of the AutoRequestor.
Preferences: Preferences will be broken up into smaller modules that will allow greater control over more items.
There will also be support for third-party' preferences screens. The new Preferences wasn’t far enough along to show how versatile it will be.
Trackdisk: The trackdisk device is now slightly faster and has better error handling for marginal diskettes drives.
The trackdisk also offers a no-click option for drives that support this. You can now have a variable number of buffers, and can get this buffer memory back when not in use.
R. I.P: I am sorry' to say the GURU is dead. He died painlessly
during the upgrade of the OS to V 1.4. He has been replaced by
“System Messages”. He was such a nice guy.
Wrap up There is so much information on V 1.4 that it is difficult to cover everything. 1 tun sure i have may have left out something out. Even so, die upgrade to V 1.4 is a substantial one that will help further distance the Amiga from tire rest of the pack. I cant wait to get it.
• AC* by John Steiner Bug Bytes The Bugs and Upgrades column The
one megabye Fat Agnus is causing a few minor, but annoying,
problems for software developers and new' users alike. The
instructions that arrive with the machines containing the new'
chip describe a modification to the startup sequence file that
must be performed if you attempt to use RAD:, the recoverable
RAM disk, As reported in an earlier Bug Byes, it seems that
RAD: will not survive a reboot with the standard A2000 2500
startup sequence. A simple modification to the SETPATCH command
in the startup sequence is required. The newly modified command
should read SetPatch nil: r. The AmigaDOS 1.3 Enhancer manual
says the r option is required for use with die Fat Agnus and
One tiling not specifically mentioned is that the “r” must be in lowercase, as the SetPatch command will not work properly if an upper case “R” is used. In fact, in the previous Bug Bytes, when 1 documented the requirement of the r option, I used die upper case letter in the sample command line. It is easy to ignore a simple thing like this and then be frustrated while trying to get the command to w'ork, Also, lie sure that the version of SetPatch you are using is
1. 32 or later.
According to the notice sent with die new' computers, several vims checking programs wiil respond widi an unknown vims alert, w'hen you use the SetPatch r opdon. This includes the program VirusX, version 3-2, the popular public domain virus checking utility written by SteveTibbet. If die virus report does noL point to a floppy drive, and occurs upon startup, you can simply click on ignore, wdien die vims alert requester appears. Be sure you are booting on a vims free disk, by checking die boot disk on a regular basis.
You can now order a new Fat Angus chip for your A500 or A2000 from any Commodore Amiga authorized sendee center. The chip retails for $ 130.00. and includes instructions for proper installation in both the A500 and A2000. The A1000 does not have the correct socket type to accept the Fat Agnus.
Although you could purchase and install die chip yourself into a 500 or 2000, lie aw'are that you will need access to a special integrated circuit removal tool, and you must cut a circuit trace or two, as well as move an internal circuit board jumper to complete the installation. Labor for installation of the chip seems to run between $ 30 and $ 50, according to a random sampling of individuals around die country who have already had the modification done.
Now that the Fat Agnus chip is readily available as an add-on, several software packages have been discovered to work incorrectly with a full megabyte of CHIP RAM. In fairness to the companies said to have problems with die Fat Agnus, newr versions of the software and upgrades will be available by the time you read this.
If you are considering purchasing any of these tides, and have the Fat Agnus, ask your local dealer, or call the software manufacturer if you are not sure whether the problem has been repaired or not. Wayne Gretky Hockey has been reported to be non-functional with the Fat Agnus. On a computer diat has the new' custom graphic chip installed, die program does nothing but spin the drive.
Deluxe Paint III works fine with the full megabyte chip installed, but unless you also have fast RAM In the machine, animation capabilities are reportedly disabled. Pro Video Pius, and its latest version, Pro Video Gold, botii have problems w'idi die one megabyte Fat Agnus. A repaired version was expected to be available in July at the latest, and the upgrade will be made available at no charge to those who need it, according to a press release by the program developers.
While on the topic of Pro Video, Sheriff Systems is offering the newly- released Pro Video Gold to registered Pro Video Plus owmers for a ten dollar upgrade fee. If you have die original Pro Video, you can upgrade to Pro Video Gold directly for a slightly higher upgrade fee. New features include two and four color fonts, anti-aliased fonts, several new' transitions and many other features. You will need to provide your Pro Vicleo Plus or Pro Video serial number when making the upgrade.
Contact Sheriff Systems for upgrade details.
Several packages seem to have trouble running in die A2000HD and A2500 with the Fat Agnus and no expansion memory7. It seems that the 50 disk buffers allocated to each partition of the 40 MB drive eat so heavily into tine available memory being allocated, that some software packages diat require one MB to run may' think die re is not enough RAM in the syrstem.
Packages with this problem will report not enough memory' errors.
.Allocating fewer buffers in the hard disk mount list is a w'ork around that will slow down disk access, but will also allow these programs to run properly.
According to a letter from Christopher Piper of Washington, DC, Super- base Professional version 3-01 has a problem with die DML command “?
Merge Text". Printer codes from text and fields such as bold and underline are not picked up as they are in the “Text Merge” command. According to Christopher, die tw7o commands are supposed to be similar. The problem was duplicated and confirmed by Precision Software, the developers of Superbase. Precision told Mr. Piper that diis bug should be fixed in version 3-02.

• AC* by Alike Morrison filew Attitude DevCon San Francisco '89
Commodore held its latest DevCon (Developers Conference) at the
Holiday Inn. In the rolling hills of San Francisco.
The location was fitting the rolling San Francisco hills exemplify' the up and down attitude of the Amiga community'.
But if this DevCon is any indication of Commodore’s planned direction, maybe next years conference will be held in Denver, Colorado, The Mile High City.
When I first arrived in San Francisco, people I talked to before DevCon were expectant and eager blit not too eager. Most attendees had been at the last DevCon, and heard a lot of things promised but never delivered, and diey weren’t going to fall for it again this year.
This attiLude faded with each seminar as Commodore showed us what they have done and what they' are planning to do. Commodore employees sent die same message in their individual seminars: “We are a team, and we want your input and feedback; we want to make the Amiga great with your help."
Most impressively, this didn’t seem like a bunch of hot air, as Commodore showed us how they have been doing it, and how they' w'ant to increase this ‘partnership' further.
Gail Wellington (General Manager, Worldwide Software and Product Suppoit, Commodore International, Limited) began by introducing Dr. Henri Rubin (Chief Operating Officer, Board of Directors, Commodore International, Limited). Dr. Rubin started by saying that Commodore and the Developers are partners, and stressed that this relationship will benefit everyone involved. He told how' a recent illness gave him more time to use the Amiga, and he explained how' he found tilings that should have been relatively easy to do, aggravating and frustrating. He said that he has a new respect for developers
who have Commodore employees sent the same message in their individual seminars: “We are a team, and we want your input and feedback; we want to make the Amiga great with your help."
Do it with 4 meg". Rubin believes 1.4 will solve many problems, adding that, “we’ve got the slickest machine around".
He noted that the addition of Arexx, scaleable fonts, and other features in
1. 4 along with monetary' developer support from Commodore the
Amiga could become the machine that we all know' it can be.
Dr. Rubin finished, then introduced the newr President of CBM USA, Harold Coppeiman. Mr. Coppennan is a 20-year IBM veteran (he left as National Director of Marketing-Academic Information Systems Business Unit), and for 2 y'ears served as Apple Computer’s Vice President ol Eastern Operations. Although Mr. Coppennan has only been at CBM for about 40 day's, he has already put his finger on some of the major problems at CBM. He started by citing marketing as the main problem w'ith US sales. (He almost received a standing ovation.) He rhen outlined five goals for the next year:
1) Improve CBM’s image.
• Institute an umbrella ad campaign with a single message. He
also said that Fall and Christmas advertising campaigns are
underway, headed by' a new ad agency from NY.
• Answer the phone on the first few rings.
• Hire more people.
2) Focus on the Amiga product Line.
• Copperman doesn’t want to abandon the C-64 128 line, but wants
to focus on the Amiga. He feels success is based on the
proprietary operating system of the Amiga.
• Plans to develop the 5 or 6 different vertical market niches
that the Amiga can become strong in.
He also wants to give the dealers training in software and hardware.
3) Improve distribution.
• Clean up dealer base. Get rid of the dealers who aren't
properly supporting the Amiga.
• Support dealers with training and ask the dealers to do more.
• Look for broader distribution without going to mass markets
like K-mart or Toys-R-Us.
4) Reposition CBM in the market place.
• Increase sales to schools grades K-12. He has already hired an
executive whose job is education.
• Get Amigas into higher education with sales to universities.
• Create Government sales.
5) Emphasize customer satisfaction.
IYIt. Copperman said “Happy customers buy, unhappy customers also buy, but from someone else".
• Copperman will hire a VP executive whose only job is customer
Mr. Copperman finished up by stating that developers should try to increase the image of their products with a professional look, name, and better quality manuals. He suggested that developers incorporate consistant user interfaces, to make users feel comfortable when using different programs. Programmers should write code that takes advantage of the Amiga (no more ‘me too' products) and create unique packages that can't be done on other machines.
Having been with CBM for only 40 days, it seems that Copperman has quickly evaluated some of the troubled spots with the Amiga and CBM. His speech was uplifting and had many attendees saying to themselves “maybe this is the right guy”.
If Gail Wellington has any say, Mr. Copperman will be around for quite a while. Site was quoted as saying “Some people think there is a revolving door on the Presidents office, well, I’ve got my foot in the door, and Mr. Copperman isn’t going anywhere'". Support from people like Gail and her staff will make Mr Copperman's job much easier.

Gail Wellington next listed die new products that Commodore has been or will be releasing (see box on page
65) . The list is rather impressive, and we can hope diat die
‘real soon now' really is real soon.
Commodore seemed adamant about not giving release dates for products that are not available now. It seems they have learned from the past. Anodier missing bit of information was pricing.
Andy Finkel (Manager of Amiga Software, Commodore- Amiga) oudined die changes and new features of 1.4. Please see "Vl,4; A Pre-preview".
The rest of DevCon was a series of seminars giving on different aspects of Commodore’s products and VI.4 of die operating system. Each seminar was headed by a Commodore employee who is actually working on the topic being covered.
This was very* nice for developers because it gave diem an opportunity to ask questions, give feedback, and make suggestions. Not only did Commodore welcome die feedback, but it wanted die feedback.
The show on a whole seemed to be upbeat and had some atendees walking out at die end of seminars saying things like “They actually implemented such-n-such” and “They're actually listening to us". It certainly seems as though Commodore has taken a step in the right direction, and a big step at that.

Notes the C if rout) Directing programs via the Command Line by Stephen Kemp In previous columns, only a few' (if any) of the programs presented required any user input during execution. Everything was “hard-coded”, which usually makes a program very limited in its usefulness. There are, however, a number of ways to increase a program’s usefulness by providing it with external (and variable) information. One way to direct a program is to provide information via the “command line".
The command line refers to anything included after you type the name of the program to be executed, and before pressing enter.
1 GENERIC TEST.C TEST.BAK In the above example, the command line contains the characters that occur after the “! " which represents the DOS prompt. Note two things about the command line. First, it includes the name of the program that is executing (in this case, GENERIC). Second, in C the command line is not provided as a whole, but is divided into multiple elements. (We’ll discuss this in detail later.)
Any C program can reference the command line by adding two parameters to the “main" function at the program’s beginning. These two arguments are usually named “argc" (argument count) and "argv” (argument variables), As I mentioned, the command line is divided into individual elements.
The number of elements is reported in the count variable (usually a short integer). The second parameter is an array of pointers to the individual elements. Thus, the declaration for the main function for a program which intends to read the command line should look like this: Deciding which definition to use is a matter of personal preference since they both define essentially die same thing.
The advantage of the first method is that die array can be indexed any number of times via subscripts. The second method can avoid subscript overhead but will require “extra” code if the program needs to examine the command arguments more than once. What the program intends to do with the elements usually determines which method will be the best to use.
The names you choose for these two variables is only important if you wrant other programmers to understand your code. I strongly recommend that you use the normal naming convention of argc and argv. Be sure to check in your C compiler manual whedier the argument count is a short or long integer. If the documentation merely states “integer", die count will be die default type used by the compiler.
Standard C provides the "startup” code necessary to divide and count the elements named on the command line. The standard practice is for this startup code to parse die command line into groups of non-spaced characters. This -was probably die difficult way of saying that the elements of the command line are space delimited, A null (0) is placed after each group making it a valid string variable. The array of pointers merely contains a pointer to the beginning of each string of characters.
This means the number of spaces between the words are not important. The command line displayed earlier couid have looked like the following example and accomplished the same thing.
1 GENERIC TEST.C TEST.BAK main( argc, argv) short argc; char "argvQ; Alternatively, die second parameter can be declared as a pointer to a pointer of characters: * argument pointers" char "argv; * program start ’ * argument counter * * argument pointers * You might wonder how you can include a “phrase” or sentence on the command line without it being chopped up.
Well, most parsers recognize and require “quoted” strings to be one element. By preceding the first word of the phrase with a quote and trailing die last word with a closing quote, we could include any number of words and spaces as a single element.
(Note: You can write programs like ECHO (provided on your DOS disk) which accept a string without quotes, but Lite original command Line must be used before parsing. If you are interested in tliis approach, read througli your C compiler manual to determine whether such a variable is available.)
Remember, the program name is reported as an element from the command line. Therefore, if the argument counter reports only 1 element, then only the program name was entered on the command line. A check for the proper number of arguments should probably be included very early in a program. Why spend time making die user wait for any number of startup events only to discover that the parameters were insufficient?
In my programs, I like to include a short set of instructions that can be printed to the console if too few or an incorrect number of parameters are included on the command line.
Usually, this “note" contains the tide and version of the program as well as an example of die required command line. This usually saves me from having to answer that “How do I start this thing?" Quesdon from everybody that gets die program.
Since we know that the beginning index for arrayed variables is zero, it should be easy to deduce that argv will contain (or radier point) to die name the program was invoked by. At first glance, it may seem odd that die name of the program is included as one of the command line arguments.
Actually, drere are several reasons why this is supported.
Some operating systems provide ways to give one program multiple names. These synonyms all execute the same program, but the program might perform alternate tasks depending on die name it was called by. Also, by examining the name, the program may determine whether it was executed from a specific drive or directory not included in die search path.
Finally, the first argument may also help to determine whedier the program was called from die DOS command line or executed from another program. For our purposes, your programs will not care what name is used, so assume that indexing into the argument variable array begins with one.
Referring back to the command line that I have already used, you should be able to describe what the program will know once it has started;
1. Argc will be 3
2. Argv is a pointer to the word GENERIC
3. Argv[l] is a pointer to the word TEST.C
4. Argv is a pointer to die word TEST.BAK For your perusal I
have included the source to a small program demonstrating the
use of the command line. This program is named GENERIC because
it forms the basis of many programs I hope to describe and
include in this column in the future. The arguments on die
command line are assumed to be file names or file patterns
that might match multiple files. The pattern matching is
provided via the library that accompanies die Manx C compiler
If you have Latdce C, you may need to replace the funcdon “scdir" with a function of another name, or you may have to write an "scdir” function using several funcdons provided in the Lattice C library'. Be sure to check your reference manual to see what is available. Also, the function named “access” is merely a function to determine if the file exists. If Lattice does not provide a similar function, substitute and open and close function (diis is probably what we will eventually do anyway).
Type it in and try the program. Once you are satisfied tiiat it works correcdy, set it aside and make a copy of die source to anodier name. Then use the new copy to do further experiments. You can learn a lot from experimentation.
Listing One GENERIC,C * GENERIC.C is a program intended to be used as a starting point * for a variety of "utility" programs.
* This version uses the MANX 3.6 standard library.

The bits of information are gathered by a third party source from whispers inside the industry. At press time, they remain uncomfirmed and are printed for entertainment value only. Accordingly, the staff and associates of Amazing Computingr'' cannot be held responsible for the reports made
in this column.] The story of the secret Epyx machine can now be told in full, and it will no doubt become another Silicon Valley legend. As you may know, some of the original Amiga development team (Dave Needle, RJ Mical, and Dave Morse) were hired by Epyx about a year ago to create a super-secret hardware device (code name: Potato). Lips were zipped tight, but everyone agreed that whatever they were working on would be stunning. Well, the Bandito’s sources were correct they were working on a revolutionary hand-held video game computer.
The specs look something like this: a 65C02 running at 4 Mhz (four times faster than a C64), 64K of memory, a 3", color LCD screen with a resolution of 160 x 102 pLxels, 16 colors out of 4096 color palette. Dave Needle created a nifty sprite engine for the Potato, allowing unlimited sprites drat can be flipped, rotated, distorted, etc. in hardware.
Hardware collision detection, double-buffered animation, color cycling are included, as is a serial port that runs at up to 62,500 baud to connect up to 16 units for “network" games. There's a “joy pad” and several buttons available for controls. Game cards (about die size of a credit card) can hold up to 2 megabytes of ROM or battery-backed RAM or a combination of the two. The unit would run about 4 hours on batteries (rechar- gable widt an adapter). Four-channel sound output (mono, not stereo). Target retail price: $ 149-95.
Of course they used an Amiga- based development system to work on the hardware and software. The screen resolution is almost exacdy one-quarter of a low-res screen, and the Amiga's multitasking makes software development much easier. The work progressed, and according to reports they even brought die project in on urne and under budget. But all was not well in Epyx land.
Unfortunately, Epyx did not have a good Christmas this year no hits to speak of. So they began to get nervous about dieir big expenditures on this unproven hardware project. They were even more nervous at die thought of the money needed for production and especially promotion, and die effort to get people to develop software for the machine.
Then came the news that Nintendo was also developing a handheld video game machine, called Game Boy (quickly dubbed Lame Boy). The Nintendo machine is technically inferior black and white, no sprites, and so on, but it's priced at $ 89.95 and has die enormous monetary mass of Nintendo behind it. So between die lousy cash flow and the looming Juggernaut of Nintendo, Epyx decided to sell their technology to a larger company, one that had good distribution, a track record in the field, enough money for good promotion, willing to battle head-to-head with Nintendo, and of course a company headed
by people who are genial, friendly, and trustworthy. Epyx sold it 10 Atari.
You can well imagine the chagrin the loyal Amigans on the project are feeling. (This isn't die first time they have had to seil their technology for another company to market, if you get the drift.)
However, it appears diat Atari is really going to try hard with this product, if for no other reason than they don’t have anydiing else interesting to sell. The one redeeming point in the whole deal is the fact that the development system is on an .Amiga and cannot be ported to an ST for performance reasons. So if Atari wants software developers, they have to sell them an Amiga system. (That distant sound is the silver}' tinkle of laughter).
All software development efforts will apparendy be coordinated by RJ Michal at Ep}x. The target is to have a number of machines and game ddes in die stores for this Christmas. The Bandito will be watching to see if it happens.
Hmm, wonder if you could hook it to an Amiga to play games against an Amiga opponent?
What else does Atari have going?
Well, they have high hopes for their IBM-compatible portable that’s about the size of a video cassette. It s called the PC Folio, and it should be out this summer of course that's only if you believe Atari (the company famous for announcing and never shipping). Supposedly the Epyx machine is a much better bet to ship soon, since the design was completed already by Epyx.
Oh, and according to recendy published interviews with the Tramiels, Atari thinks they are going to make a comeback with the ST in the U.S. market.
They must be a few bits short of a full byte over there, or maybe they have some RAM errors. Any support for the ST now is too little, too late. There’s no more software support from any company big enough to have a payroll, so it's going to take a miracle to revitalize Atari ST sales.
One final piece of Atari news: Atari has lost its lawsuit against the former owners of Federated stores. You remember, they said Federated had overcharged them for the chain of electronics stores, and they wanted a rebate. Well, since Atari cannot get any money from them, Atari is closing the stores and looking even harder for a buyer, but nobody's interested.
Nintendo is really making the entertainment software business run scared. Especially since Christmas was rough for many of the big publishers (Mindscape and Epvx in particular had a lot of software returned unsold after Christmas).
Even Up The Score!
Predictably, the publishers tended to blame somebody else (Nintendo) for taking away their software sales. The publishers would love to see Nintendo replaced by something that offered an open system (where anybody could develop software and not have to be licensed by Nintendo). What will replace it? Leading candidates all look like closed systems (Nintendo's 16-bit, NEC's PC engine, Sega’s Genesys box) except for Amiga. Will Mr. Copperman decide to take the plunge and make the Amiga- based game machine?
While we're talking Nintendo, they are negotiating a deal with AT&T to provide a Nintendo-based teletext service. All the usual stuff home shopping, etc. The difference is that there's a huge base of Nintendos out there. What's next? Will they be adding keyboards and disk drives? How will they make the jump to tire next generation of hardware? That’s where other manufacturers hold out hope. They have basically given up on trying to beat Nintendo with their current hardware, and they are trying to outflank them to win the battle of the 16-bit machines.
What does the new generation of home video game hardware look like?
The Bandito digitized some photographs of NEC’s PC Engine on a secret test drive in the U.S. and here are the results.
The PC Engine is based on a 7 Mhz 6502 with a graphics coprocessor for fast sprite action. It hooks up to a regular TV and offers a 5)2 color palette, all on screen at once (individual sprites can have up to 16 colors). Lower resolution than Amiga (at about 256 by
160) , and the sound is nowhere near as good.
The most interesting part is the CD ROM player option for $ 500. This player can play CD-ROM's created for the PC Engine or it can play standard CD audio discs. And with an additional interface it’s also a CD-ROM player for a PC. Retail price is $ 200, and it should be introduced this fall. Games can be on CD- ROM or on credit card-like ROM RAM cartridges with up to 2 megabytes of memory.
The new Sega Genesys unit is even more impressive. It’s built around a 68000 with a 256 color palette (out of 262,000), higher resolution than the PC Engine, and a Z80 dedicated for sound output, There is also a modem option to encourage 2-player gameplay over the phone lines. It’s due this fall, too. And Nintendo's 16-bit machine is rumored to be even more technically impressive, though it will not arrive until sometime next year.

So it looks like die Amiga is going to have some tough competition in the game machine business. Commodore still has a window of opportunity to make the Amiga 2500 a player in the marketplace, or better still drop the price on the Amiga 500 and push it into the mass markets. But that opportunity will be gone by the end of this year.
In other news, things have been tough for some people in the Amiga magazine business lately. One newcomer has succumbed to the pressures of the marketplace, and another major magazine is undergoing a major editorial shake-up, The magazine business is tougher than it looks, says the Bandito.
Big game makes a killing Speaking of tough businesses, the 1988 sales reports are in for the big entertainment software companies, and it’s very interesting. Electronic Arts is number one with $ 67 million, Medi- agenic is next with $ 60.6 million, then Broderbund at $ 46 million, and Epyx at $ 36 million.
Don’t expea these numbers to grow at the heated pace of the last few years; sales will be up, but probably on the order of ten to twenty' percent. This year Electronic Arts is expected to go public, and Broderbund may revive their attempt to go public as well.
The European software market is accelerating faster than die U.S.market, and American software companies are scrambling to take advantage of the situation. Electronic Arts has given up on their attempt to establish direct distribution in England. Apparently, the Brits just like to buy things through distributors, rather than direct. Accolade has cancelled their distribution agreement with Electronic Arts in Europe; they're setting up their own office to handle European sales.
Software Toolworks Iras become an independent software publisher and will no longer distributed by Electronic Arts.
On the other hand, Electronic Arcs has picked up New World Computing, formerly distributed by Mediagenic.
Dynamix, a software development group known for simulations like ArcticFox, has become an Affiliated Label of Mediagenic. And Microlllusions is no longer distributed by Mediagenic because of poor sales. Round and round they go, where they stop, nobody knows... VIDEO SOFTWARE 3D Options

110. 00 Mediagenic announced results for their fourth quarter
ending in March, and for the fiscal year. Sales grew 11%
over die year-earlier quarter, from $ 13.1 million to $ 14.6
million. But income headed in the opposite direction, from
$ 874,000 last year to $ 25,228 this year.
For the year, their sales were $ 60.6 million, a 34 percent increase over last year’s S45.3 million. But their income this year was $ 1.1 million compared to $ 3.6 million last year.
According to the Bandito’s 7.16 Mhz calculations, diat’s a profit percentage of a measly 1.8%. Grocery stores do better than that. The Bandito chinks the managers at Mediagenic are feeling the pressure, fingering their necks when the Board of Directors walks by. If their profit picture doesn’t improve by die fall, watch out for rolling craniums. In a sign of the pressures, their Infocom division moved to Mediagenic’s California offices in a cost-cutting consolidation.
2414 Pendleton Place ¦ Waukesha. Wl 53188 ¦ 9 AM to 5 PM M-F All is not rosy at some of the other publishers. According to sources, Mindscape had a rough Christmas and dumped a large number of its employees recently. Epyx also tightened its belt after disappointing year-end results. The big guys are trying to look lean and mean, anticipating a tough battle for market share this year.
Another piece of news that makes it tough for the entertainment software business: Toys "R” Us is no longer carrying MS-DOS software. Does this mean they'll drop Commodore’s Colt line? Why did diey do this? Well, tine stuff just did not sell. It seems that MS-DOS owners buy maybe one game when they get the machine and that’s it, unlike C64 or Amiga buyers, who keep on buying games. Toys might be interested in marketing the Amiga if the price point was right. But is Commodore still interested in marketing die Amiga through Toys? We shall see.
Yet another publisher joins the fray: Gold Disk, not content with professional productivity and home creativity, has launched a new game line called Hardwired. Their first titles appear to imported stuff from Europe, Jeepers, there must be a whole lot of games being wrirten in Europe that we never see over here. It’s probably a good tiling, too.
News from Europe Cinemaware is also expanding its product line by importing products from Europe. They’re trying to pick the more technologically advanced games, though diey will be in categories unlike their current software. Look for more European imports from many companies, as they use the greater popularity of the Amiga in Europe to meet their software development needs.
Several of die big .Amiga developers are already getting more of their sales in Europe than in the U.S., and there’s no sign that this will change any time soon.
The sawy developers are strengthening dieir presence in Europe to take advantage of the larger market.

414-544-6599 Visa MC COOs While we’re talking about Europe,
the Bandito has heard about another disturbing situation.The
European market is very different dian the U.S. -Europe sees
the A500 as a game machine, mosdy with one disk drive and
512K. Of memory, with a TV set as die monitor. The
U. S. sales are oriented more toward A500's or AZOOO's widi at
least two drives and maybe a hard drive, and almost everybody
has a megabyte or more of memory. So the game players are in
Europe, and die productivity machines are in the U.S. Circle
134 on Reader Service card.
Seems like Commodore could make some real bucks by learning howto sell A2G00’s to European businesses. It shouldn’t lie hard since they already have a longstanding reputation diere as a business computer manufacturer, and their PC done line has done well. In die
U. S., they should position the A500 as die home computer of
choice, and sell it through the mass-market channels just as
they did widi the C64.
So what’s the hold up? Why are they waiting to use this rather obvious strategy? The recent management reshuffling must, by necessity, slow down high-level decision making.
Hopefully, it won’t kill decision making entirely. Let's hope we see tire Amiga firmly in the mass markets for hearty Christmas sales, with the more profitable A2000 being pushed even more heavily through the established dealer network, along with all the profitable peripherals.
But A2000’s already sell quite well in one country West Germany. Check out these West German street prices: Amiga 500 = 97SDM, and the Amiga 2000 = 169SDM. At the current rate of exchange, dial’s an A500 for under $ 500, and an A2000 for less than $ 850. Now, the A500 price isn’t much different than the U.S. price, but the price difference for die A2000 from die American street price is amazing. At those prices, die Bandito wouldn’t be surprised to see some West German A2000’s showing up in the U.S. soon.

OK. OK, the Bandito has gotten the word about X-10 control programs.
There are at least two out there- one from Complications in Redlands, CA and one from Digital Dynamics in Santa Monica, CA. See? All ya gotta do is ask, So if you want your .Amiga to control your home, all you need is one of these programs and the X-10 modules to plug into your coffeemaker, lamps, TV set, and so on.
HAM Paint Wats Latest salvoes come from NewTek, promoting Digi-Paint 3 bv offering owners of PhotonPaint, DeluxePaint II or Deluxe PhotoLab to upgrade to it.
Predictably, Microlllusions and Electronic Arts are not amused. According to spectators, Digi-Paint 3’s “Saclisy" interface looks much nicer than die usual two-color job. The Bandito likes die way die interface doesn’t scrunch down when you’re in interlace mode more programs should do it that way.
Electronic Arts has done some limited advertising for DeluxePaint III and has continued to sell DeluxePaint II at a reduced price, since DeluxePaint III primarily adds animation features rather than new paint features. Digi-Paint 3 lacks animation but has all the HAM features. Photon Paint has HAM animation, but not with all die tools of DeluxePaint III or the sharp interface of Digi-Paint 3. You're paying; take your pick.
Tije World of Commodore The World of Commodore show in Los Angeles was a bust in die opinion of die exhibitors. Commodore pushed developers into displaying there, but attendance was dismal. As an example of the sterling marketing efforts, flyers promoting WOC arrived at people’s homes after the show was over.
Many exhibitors swore they would never go to another World of Commodore show, at least not in the U.S. The Toronto version always attracts huge crowds, but for some reason WOC can’t get going in America.
Amigas are being used in a new type of arcade game control pods called BatdeTech, shown at CES. These are fu 11-enclosure video games with a couple of monitors and tons of controls.
The twist is that these pods are hooked together, and the players are in two teams controlling simulated giant robots in futuristic warfare. It's expensive to play ($ 6 for 30 minutes). The units are also very expensive to construct (diey contain 2 Amigas a piece, bur it’s die enclosure itself and ail the controls that are so expensive). Will there be a home version someday?
The Bandito doesn’t keep a vaporware list, but it is worth noting that the long-awaited Music-X has finally shipped. Many cheers from patient fans.
After they use the program a while, we'll find out if it was worth the wait.
On the hyperprogram front. Look for at least one HyperCard clone on the .Amiga that will read and use Macintosh HyperCard stacks. It requires some interesting conversion algorithms, but die potential is huge.
There are many stacks out there, and HyperCard has given the Macintosh a big selling edge in a lot of situations.
Now die Amiga can say, “Yeah, but take that HyperCard stack and run it in full color, full overscan, with really fast ray- traced animations and stereo sound."
That may take a bite out of the Apple.
• AC* Amazing Programming Software Development with m Lattice 5.0
by Gerald Hull For the last couple of months I have been
working on a program that should be commercially available by
die end of the year. I have been using die new 5.0 Amiga
68000-68020-68881 “Lattice C Development System” for dais
project. What follows is an account of some of die benefits and
some of the problems I have encountered.
Lattice 5.0 is a wonderful, synergistic, and sometimes state-of-the-art collection of tools for software development. It really is, as the PR says, “a complete programming environment for the Amiga." The package includes compiler companion tools, code profiler, traceback utility, source-level debugger, integrated screen editor, assembler, and optimizing compiler.
The documentation is spotty despite two full 3-ring binders. And after two revisions (5.01 and 5.02), some parts of die package (especially die compiler) remain buggy. Nothing is free in diis world. On the one hand, you get considerable power and control over software design and development. On die other, you face a stiff learning curve, and may spend time tracking down Lattice’s bugs in addition to your own.
But I would radier have 5.0 widi some problems than not have 5.0 at all, Compiler Companion Plus Lattice 5.0 includes the Compiler Companion collection of utilities (BUILD, EXTRACT, CXREF, DIFF, FILES, GREF, LMK, SPLAT, TOUCH, and VC), whicli were previously released as a separate package. Aldiough recompiled, these programs appear otherwise unchanged, and the documentation has not been updated. The FILES program remains brain-damaged; it cannot handle trailing wild-cards.
Since I recently reviewed the Compiler Companion in AC V.4.1, there is no need to go over diese programs again. It's a pretty useful collection, especially LMK, die compilation management program, and GREP, the regular expression parser. Those who bought them separately are probably kicking themselves for not waiting to get diem “free” with 5-0.
These tools are joined by others just as useful. They include LPROF, LSTAT, TB (traceback), and OMD. (The first three are new with 5.0.) LPROF and LSTAT generate an execution profile of your software. To take advantage of dieir analysis, you must first compile your program using the appropriate debugger mode of the LC compiler.
Since odier Lattice utilities use these debugger inodes, I will jump ahead a bit to describe them. By compiling with options -dO to -d5, you can control the amount of additional line number, symbol table, and data structure information included with your object files. The penalty you pay is increased compile time and enlarged program size, die latter affecting speed of execution.
However, the BLINK linker has a switch, NODEBUG, that will remove all die excess from die final executable image. It is generally a good policy to compile with the appropriate debug option, and then link under different names bodi with and without NODEBUG. This way you will have one ponderous version for die utilities that need diat extra information, and one “clean” version. By running iprof yourprog your program will execute normally (though more slowly) and you can take it through its paces. While it is running, LPROF takes a peek thirty times a second to see which line of C code is
When you quit your program, LPROF will dump its results in a file called PROF.OUT. Now you can run fstat yourprog and get a routine by routine even line by line breakdown of where your program is spending its time.
LPROF and LSTAT represent just pan of a swarm of capabilities Lattice 5.0 provides for optimizing code, a theme we shall come back to. If you are interested in making your code as fast as possible (and every programmer is), you can determine from LSTAT’s profile statistics which routines should be redesigned or downcoded into assembler.
Lattice's old and familiar OMD (object module disassembler) utility becomes extremely useful in conjunction widi LPROF and LSTAT. If you have compiled your program with debug option -dl or greater, dien omd yourprog.omd yourprog.o yourprog.c will generate a listing showing the line- by-line breakdown of your source into assembler and machine code. If you do intend to downcode, the OMD listing will show you exactly what your interface must look like.
However, when you interpret die results of LSTAT in light of an OMD listing, you must take into account that LSTAT correlates each line of C source with the machine code preceding it, instead of following it. In my program, diis resulted in the most frequendy executed line being a blank.
You implement the new TB (traceback) utility by linking your program with CATCH.O instead of the more conventional startup routine. C.O. Then if your program abnormally terminates, it will automatically construct a file SNAPSHOT.TB containing crucial information in IFF format concerning where and why the problem occurred, including die contents of all die registers and the entire stack. By running TB with various options, you can generate different readouts of that material.
The amount of information available also depends upon the debugging mode. With option -d2 or greater, you can find out which line from which routine at point led to catastrophe.
However, whether traceback works depends on the severity of the error. If it's the kind that usually results in a “Software error Finish ALL disk activity" requester, you will likely catch it with TB, Unfortunately, if it's the kind that crashes straight to a GURU, you may be out of luck.
Symbolic debugging One of the more important additions to the Lattice C package is the CodeProbe symbolic debugger, ingeniously nicknamed CPR. Until now, my debugger at the C level has been “print .” ! Output to the screen the values of critical variables at critical junctures, then try to figure out from there what's happening.
CPR is a much more powerful and useful way to debug C code. Here again you need to prepare by compiling with - d2 or greater, and linking with the ADDSYM switch. This will swell the size of the executable image by as much as a factor of 12.
In one reported instance, a program of 100,000 bytes ballooned to 850,000. This seems excessive, even given the amount of information required by CPR, and we can hope it will be reduced in future versions. Meanwhile, you will need a lot of memory to take full advantage of the debugger.
Assuming that's not a problem, you will find CPR a delight to work with. It’s a real-time version of OMD that you can interrogate at the symbolic level. The program puts up a Source window showing the code you are stepping through, either C, assembler or both (my usual choice). The line you have stopped at (in C and or assembler) is highlighted.
Breakpoints show up in yet a fourth color.
There is also a Dialog window providing a command-line debugger, a full-featured descendent of the original Motorola MACSBUG. To step through code you just keep hitting return; command line history is available through the up and down arrows.
Above both windows are a set of function key options attached to the screen and always available. They are often very useful, showing that attention has been given to interface “friendliness".
You can call up a Register window, or a Watch window that maintains the current value of user-selected symbolic variables.
You can Zoom into a window make it fullsize and bring it to front and back out, Swap back and forth between debug screen and application screen, and so forth.
The screen’s menus provide a useful subselection of command line (Dialog window) options including setting and clearing breakpoints, watching addresses or symbolic variables, proceeding to a location. Many of these commands are also available through keypad equivalents.
To go through all the capabilities of CPR would require another article. In brief, it is an excellent way to step through your program to a problematic area and probe for the causes of trouble.
It is a full-featured symbolic debugger that is as useful at “C level" as Metadigm’s METASCOPE is at tire assembly language level.
Of course, there are things you can do with METASCOPE that you cannot with CPR. For example, with the former you can position as many windows as you want over sections of memory, and watch them change in real time. You can also call up a listing of the svmbol table and go straight to the routine you want to debug.
However, with CPR you can set “watch break” points, which trigger a halt whenever specified variables change value. (This slows down execution speed tremendously, so it should be used with caution). Also, CPR allows you to snoop around in other, independent tasks, and in principle you can even switch debug control over to them.
The ideal wouid be a symbolic debugger with the power of CPR and the intuitiveness and facility of METASCOPE.
Until that comes along, CPR will do nicely. The 140 pages of documentation for CodeProbe are generally clear and well written.
LSE and ASM Two final important members of die Lattice 5.0 supporting cast are the integrated editor LSE, and the ASM assembler. The Lattice Screen Editor is a full-screen editor integrated with the compiler: it will step you through each line that registers a warning or error. It also has on-line help information, but in my environment LSE had difficulty finding its help file.
It is user-configurable via a companion program called LSEINST, so diat to a certain degree you can emulate your favorite editor. However, there me limits to this reconfigurability. For example, you cannot use the same command for more than one function, and you are not allowed escape combinations.
Once you become comfortable with LSE, you should find it a convenient way to code and debug new routines, i do not use the editor that much, however, I already use three different editors with entirely different command sets, and that seems to be about my limit. Since my program consists of a large number of different modules, I customarily compile and link with LMK instead.
ASM is Lattice's 68000, 68020, and 68881 macro assembler. It is a fully capable assembler, but requires a syntax that differs from the Amiga Macro Assembler (MetaComco) default standard. This means you will need to make some changes if you want to use it on code written in the standard dialect.
You will have to replace SECTIONS with CSECTS, get rid of EQUR and REG, and local labels. The word “MACRO" has to appear on a line of its own, unlike conventional 68000 usage. It wouid be helpful if Lattice provided a list of these and other differences. Unfortunately, their assembler documentation remains sparse and error-prone. For example, despite page G6S, the LIST, NOLIST, and SECTION directives are not recognized.
Largely for these reasons, 1 never use ASM. Instead, I stay with assemblers that coirform more closely to the default standard syntax, such as Metacomco, CAPE, and DevPac Amiga. However, if you are willing to work within those limitations. Lattice's ASM provides a perfectly satisfactory'' assembler.
Precompiled headers Of course the star of the Lattice 5.0 release is the LC compiler. There are actually two versions of the first phase of the compiler, LC1 and LOB (“B” for big).
If you use LC, LC1B is automatically invoked whenever needed to generate listings, prototypes, and so forth.
Here we find some of the most ambitious new improvements, but not without drawbacks. Lattice has gone all out to both speed up the compilation process, and help you produce tight, fast code. However, the changes have left a few bugs in their wake, and you cannot always find clear instructions on how to 0 neTS'

However, optimizing is a bit of an art, and what works best in one situation may not be appropriate in another.
According to a BEX notice by John Toebes, Manager of Motorola C Compilers for SAS Institute, the owners of Lattice, the compiler works best for subroutines of forty lines or less. You should work toward that target if you want to take best advantage of this capability.
Multitudinous insects The major drawback of Lattice’s new compiler is a disproportionate number of bugs. Everyone recalls the Orson Welles wine commercial in which Welles solemnly intoned, “We will sell no wine before its time. ’’ Lattice is no Orson Welles. After two revisions and closing in on a third, they have already corrected well over a hundred different bugs.
Now this is just too much! They are making their established base of users debug their software, and they are making the users pay for the privilege to boot. Of course the good news is that you need not worry about all diose bugs if you get the latest release.
The bad news is that the compiler Circle 140 on Reader Service card.
Is still not bug-free after all this. I have come across three bugs in the compiler so far that are not included in those already fixed. I have mentioned two; the third is the tendency of LC1B to crash when you ask for a cross-reference symbol table C-gx). Since I have made no special effort to ferret out bugs, unless I am cursed, other Lattice 5-0 users should expect to run into similar difficulties.
To some extent the problems with bugs and documentation are countered by Lattice's excellent software support.
They maintain their own BBS and have a technical support hotline, in addition to their conference on BIX. They are also on other networks. For example, you can find JTOEBES and CARLATTICE (Carlotta Deconcilis) on PeopieLink.
You can learn a great deal from these sources. In particular, I have gained a lot by monitoring tire conference on BIX. However, you can work up a pretty healthy phone bill in the process. Also, you may not always get the response or the information you are looking for. So far, only one of my bugs has been “officially” recognized: there has been no reaction to the other two.
Under die circumstances, one would til ink that Lattice would be extremely interested in confirming or denying new bug reports.
Conclusion I do not regret having chosen die Lattice C 5.0 Development System for my commercial efforts. As I said at the start, I’d rather have 5 0 with problems than not at all. I suspect many programmers would agree with me. It provides a powerful range of development and

Programming Executing Batch Files in AmigaBASIC by Mark
Ayelellotte Many times I have wished drat I could copy files
with an AmigaBASIC program, format and copy a disk, or perform
some other AmigaDOS trick. Unfortunately, most .AmigaBASIC pro
grammers are led to believe these sort of complex operations
are better left to other languages. They are told that BASIC
lacks the proper commands, or simply is not capable of such
Fortunately, these pessimistic accusations can be laid to rest. Indeed, .AmigaBASIC is capable of executing .AmigaDOS commands from within a program. It can even execute a batch file chock-full of AmigaDOS commands. Furthermore, it can pass parameters or variable values to these batch files, allowing the user to customize disk operations.
How can this be accomplished? Well, it's a long story, so let me start from the beginning to make comprehension as painless as possible.
AmigaDOS batch files An AmigaDOS hatch file is simply an ASCII file containing a list of AmigaDOS command strings. A batch file is executed using the AmigaDOS EXECUTE command. Executing a batch file is equivalent to typing each command in that file, into the CLI, one at a time. It's obvious that a frequently-performed and time-consuming task, such as creating a new Workbench disk, could easily be reduced to a single-command operation: EXECUTE MakeWbDisk The batch file MakeWbDisk may contain the necessary AmigaDOS commands to initialize a disk, create several directories, copy vital Workbench
files and install the disk.
However, what if you want the file to custom-name the disk? You could change the file with a text editor each time you want to make a new disk, but that would negate the convenience of using a batch file. Thankfully, there is an easier way.
The .KEY statement lets you define variables to be used in a batch file. This statement should appear as the first line of a batch file so that no attempt may be made to access variables which have not yet been defined.
There seems to be no limit on the length of variables, nor on the number of variables that can be declared. However, all variable declarations MUST appear on the same line as tire .KEY statement. There also MUST be only ONE .KEY statement. After you declare a variable with the .KEY statement, simply surround the variable name in herringbones when referring to it throughout the file. A few lines of a sample batch file may look something like this: .KEY DiskName FORMAT DRIVE DFO: NAME DiskName NOICONS A batch file containing these two statements would format a floppy disk in DFO:, without
creating a Trashcan directory’, and label it using the name specified in the execution statement.
At this point, you’re probably wondering, "How do 1 execute a batch file containing variables?" Well, this is tire really easy part. Just type: EXECUTE SampleFile NewWB This statement could execute a batch file named SampleFile, consisting of tire previous two statements. The word NewWB would be passed to the variable DiskName. Therefore, a clisk in DFO: would be formatted with no icons and given the name NewWB.
But, what if you wanted tire option of specifying the disk drive where the disk will be formatted? To declare more than one variable, just separate the variables in the .KEY statement with a comma. The new statements would look like this: .KEY DiskName,DeviceName FORMAT DRIVE DeviceName NAME DiskNarae NOICONS To execute this batch file, type EXECUTE SampleFile NewW3 DFO: Notice that the parameters to be passed to tire batch file are separated by spaces. This means that if a parameter contains a space (e.g. NewWB), it must be enclosed in quotes. This makes the execution statement look like
this EXECUTE SampleFile "New WB" DFO: As you can see, passing parameters to batch files is ultimately more practical than changing the file itself for each new operation. Now, you are probably asking one of two questions: 1) What does all dris have to do with AmigaBASIC?; or, 2) I wonder what's on TV? Well, regardless of how interesting this article has been so far, I will proceed to answer the first question.
This has important applications in AmigaBASIC. If you have several Workbench disks (as I do) and each one uses a different ram device (i.e. VDO:, RAD:, and RAM:), a basic program could benefit from using batch files. Particularly, if that program chains to many independent subprograms, it can load drose subprograms into tire appropriate RAM device to speed execution. By prompting the user to choose the destination path to which the files may be copied, it would not be necessary to reboot with the ''correct" Workbench disk just because a basic program insists on using a ram device that is not
AmigaBASIClibrary commands Fortunately for the AmigaBASIC programmer, this version of Microsoft BASIC allows a fairly simple way of accessing AmigaDOS libraries which contain machine language routines.
However, before BASIC can use one of these system libraries, it must have a list of all the routines in die library and a description of each routine’s parameters. This information is supplied in die FD (Function Description) files, found in a special drawer on die Amiga Extras disk bearing the file extension Jib.fd. This drawer is called FD1.2 (on the 1.2 Extras disk), or FD1.3 (on the 1.3 Extras disk). The program that converts these FD files to a format readily understood by BASIC (called die .bmap) is named, appropriately, ConvertFd. It can be found in the BasIcDemos drawer on the Amiga
There is a major difference between the 1.2 version of ConvertFd and the 1.3 version but diis will be discussed a litde later.
Once a .bmap has been created (such as dos.bmap from dos.library), AmigaBASIC may access the corresponding system library with the LIBRARY command. LIBRARY is an AmigaBASIC command that opens a library of machine language routines and adds them to BASIC, thus making them a part of the AmigaBA- SIC “reserved word" list. For instance, LIBRARY "qos.library" would open die dos library. Notice that the library is not referred to as dos.bmap, but as dos.library. This is because the dos.library is die library' to be opened B.ASIC will automatically search for the corresponding .bmap file, either in
the LIBS: directory or the current directory'. Since dos.library is a filename, not unlike a filename in an OPEN statement, it must be enclosed in quotes. The AmigaBASIC programmer uses the LIBRARY statement to tell BASIC the name of the system library diat needs to be opened.
When all work with libraries has been completed, the LIBRARY CLOSE statement can be used to close all libraries which were opened with die LIBRARY statement.
Now that you have an abundance of new' commands at your disposal, how do you use them? Well, after opening a system library, you must decide which machine language routines are to be used. Next, you must discern which routines are subprograms and which are functions. This information, as well as detailed descriptions of all the routines in each library' (up to, but not including, new AmigaDOS 1.3 libraries), can be found in the Amiga ROM Kemal Manual. Discussions on the use of the library functions used in diis article may also be found in The AmigaDOS Manual within die AmigaDOS Developer’s
Manual section under Chapter 2, “Calling AmigaDOS."
Most library routines are functions, but a few are subprograms. A subprogram may be called simply by typing its name and supplying the appropriate parameters. A function, on the other hand, is a liitie more involved. Library functions, like all user-defined functions in AmigaBASIC, must be declared before they may be used. The statement that declares functions is (believe it or not) the DECLARE FUNCTION statement.
An important function pertaining to diis article that can be found in the dos library is the Execute function. This function is used to execute AmigaDOS commands from AmigaBASIC. To declare this function, you would type: DECLARE FUNCTION Executes LIBRARY The Execute function could now be used in a program, provided diat die DOS library lias been opened.
There are a few subde, yet crucial, items to note about this declaration. It should be observed that, although AmigaBASIC does not give a flying flip whether somediing is written in upper or lower case, AmigaDOS gets offended by improper case usage. Therefore, the first letter of the Execute function is capitalized because that is the way Execute is spelled in the DOS library. Also, it is vital to know that all library' functions accept and return only long integer values. Thus, Execute must be followed by &, which denotes a long integer in AmigaBASIC.
Since functions return values, they cannot be used by themselves. They must be used in an expression. The syntax for using the Execute function in AmigaBASIC is: x = Executes ( commandstring, input, output) The value returned by die Execute command is a boolean
(i. e. true or false) value that is stored in the variable x.
There’s no need to worry over what is stored in x. because
there is no reason to use it. It simply satisfies the
condition that a function must be called within an
expression. The commandstring is actually die beginning
memory address of a string, or a combination of
concatenated strings, terminated by the null character
CHR$ (0). Input and output are long integer values that
specify die input and output padis for die Execute command.
For now, these will just be set to 0. Executing an actual
AmigaDOS command from AmigaBASIC would look somediing like
this: x = Executed ( SADD( "Info ram:temp"+CHRS(GJ ), 0, 0 )
Notice diat the command string is in quotes and is followed
by a null character. SADD is an AmigaBASIC function that
returns the memory location of the first character in a
Hence, the Execute function will start reading string information at the memory location specified by SADD, and will stop when it reaches die null character. Executing die above command in AmigaBASIC would be identical to entering die CLI and typing: 1 info ram:temp The result of either method would be a file named temp in volume ram: containing information on currendy mounted devices.
Another function in the dos library' relevant to this discussion is die Open function. Open opens a path to any mounted Amiga input or output device and returns a value, called a handle, that can be used to reference the input or output path. The syntax in AmigaBASIC for Open is: handles = xOper.S ( name, accessmode ) The handle& is a long integer variable tiiat contains the handle used to access the opened path. The name is just a string consisting of die name of die i o device. It is passed the same way as the string in the Execute function; that is, it is terminated with a null character
and the beginning memory' address of the string is passed, rather dian the suing itself. The accessmode may include one of diree values. The first possible value is 1004, which tells the Amiga to open a file for input and output. The second value, 1005, tells die Amiga to open a file Conn act ions Two errors appeared in die article Building tbe Amazing Stereo Audio Digitizer (f AS).

For input. The third possible value, 1006. Tells the Amiga to open a new file for output. Since Open is a function, it must be declared with the AmigaBASIC DECLARE FUNCTION statement before it may be used. The x prefixed to the word Open will be explained shortly. To open an output path to NIL:, one could simply type: OutS = xOpenS ( SMD( "NIL:"+CHRS10) ), 1006 ) The last library routine we will use in this discussion is actually a subprognim. The Close subprogram closes an input or output path opened by the Open function. Since Close is a subprogram and not a function, it does not need to be
declared as a function, nor does it have to appear in an expression, it must, however, be executed by itself - like all other AmigaBASIC subprograms. Closing a path opened by the above statement is as easy as typing: xClose C oii£& ) Because Close does not return a value, there is no reason to append & to its name; but its parameters must still be passed as long integers. But, wait a minute. There’s that little lower case x again. Maybe it's about time I explain this little phenomenon.
T) je 1.3 difference Those who have used AmigaDOS 1.2 with
.AmigaBASIC (I assume I am speaking to the majority) may have
tried to use a little routine that allows BASIC to read a
directory using the dos library’s Execute function. This
routine works fine as long as AmigaBASIC is staited from die
CLI. However, running AmigaBASIC from the Workbench, via
icons, and attempting to execute this routine will cause a
visit from the Guru. Most people purchase die Amiga because of
its Intuition interface and ease of use. The last thing diey
want is to have to do use die CLI and the keyboard to perform
a function better accomplished by two clicks of the mouse.
Have faith, diough, for dicre is an answer.
According to the documentation on the Execute function in The .AmigaDOS Manual, Execute uses the current output window, unless one is provided for it. In either case, Execute MUST have an output window. When AmigaBASIC is run from the CLI, that Clt window becomes Execute’s output window.
However, Workbench does not open an output window for each application that is executed via icons.
So now we know two things; 1) Workbench does not open an output window for AmigaBASIC; and 2) die dos library’s Execute function must have an output window to function (no pun intended) properly. Since Workbench does not provide an output window for AmigaBASIC, the Amiga crashes when an AmigaBASIC program containing Execute is run from the Workbench.
To compensate for the Workbench’s lack of an output window', we must open our own. This is accomplished by using die Open function. There’s only one problem: the 1.2 dos.bmap lists the Open function as Open. Unfortunately, BASIC also has a command called OPEN. An attempt to call the function Open would be misinterpreted as an improper usage of die AmigaBASIC OPEN statement. The same dilemma exists for the Close function. On the other hand, the 1.3 dos.bmap file lists Open as xOpen, and Close as xClose. By prefixing an x to these troublesome names, they may be used in AmigaBASIC without any

Other library functions known to conflict with AmigaBASIC reserved words are: abs Exit. Input Output Bead tan Translate Wait Write Each of diese functions may be used by prefixing an x to its name. If you are skilled enough, you may wish to modify' the 1,2 version of ConvertFd, allowing it to make .bmap files with these changes in spelling. On the odier hand, if that sounds a little too complicated, then this may be the perfect incentive to finally invest in the 1.3 operating system. Either way, die demo program provided in this article may still be executed from the CLI, after some minor
Now that we know why Open is addressed as xOpen.we need to use it to open an output window, The output window we will use is NIL: , or essentially, nothing. Under normal operation, the Execute function will never use this output window, so there is no reason to see it. Also, NIL: requires less memory than an AmigaDOS window; it will not clutter the screen; and it satisfies the Execute function's craving for an output window. Opening a padi to NIL: could be accomplished with the Open statement mentioned previously.
Explanation of the program The program in Listing 2 illustrates a practical application of these library' commands. Its purpose is to read a C: directory and copy' specified commands to die ram device of die user's choice.
The batch file in Listing 1 must be typed into a text editor and saved under the name CopyFiles.BAT before the demo can be run. The first line of die file is the .key command diat declares diree variables: sdir, ddrir and filename. After declaring die variables, the file makes die source directory (sdir) die current directory. If the destination C: directory (ddir) does not exist, the file creates one. Following then, it executes the batch file (ram:Copy.List) created by the demo program and assigns die C: directory to the destination directory*. When it has finished, the file turns the
current directory* back over to SYS:.
If y*ou are going to be using the 1.2 version of dos.bmap, and executing AmigaBASIC from the CLI, then there are a few changes diat should be made to the program.

(508) 851-4580 (603)893-9791 should be changed to and the
statement containing the xClose function should be deleted.
The last thing to be changed is the way the program is
executed. The program must now be executed from the CLI by
typing: i AmigaBASIC "Demo" Other than the calls to
subprograms, the demo program executes in basically the
order that it is written, so it should be fairly easy to
follow. Because the format of this magazine is restricted
to 60 characters per line, some of the command strings in
the Execute functions were defined in previous lines and
then inserted as string variables. As a result, the code is
much easier to read. However, this method takes up more
space in memory, and it really isn't necessary'. A few
subprograms do need some further explanation, though.
The first one is the MountList subprogram. Using the Execute function, this subprogram executes die AmigaDOS INFO command, directing its output to a file in ram: called temp. The INFO command provides a listing of information on currently mounted i o devices. The subprogram loads this information into one variable.
“Why one variable?”, you ask. Because it is much faster than using a separate variable for each line in the file. Also, checking for a mounted device is as easy as using die AmigaBASIC 1NSTR command. If the INSTR command returns a zero, then the device we are searching is not mounted. The information obtained by the INFO command is passed back to the main program through the parameter, mountedS, of MountedList.
The Dir subprogram is the most important of the subprograms. It uses the Execute function to execute the AmigaDOS LIST command, directing its output to a file in ram: called temp. The directory listed is the source C: directory, which is passed through one of Dir's parameters, voIume$ .
Once temp has been created, anodier file. Temp2, is created and used to hold die names of die commands which are extracted from temp. After the commands have been extracted and temp has been killed, the Execute function is used once again to execute the AmigaDOS SORT command. Temp2, which holds die list of C: commands, is sorted, and the resulting list is stored in temp, The final, sorted list of C: commands in temp is loaded into an array called commandSO- This final list is the one from which the user can choose die commands to be copied.
The routine marked as Construction of a Batch File shows how a batch file may be created from within an AmigaBASIC program. The program must open a sequential file and use PRINT (instead of WRITE ) to send die information to the file.
The WttlTE statement inserts delimiters (i.e. commas, quotes, etc.) which will corrupt die batch file in the eyes of AmigaDOS.
On die odier hand, die PRINT statement will send information to the file exacdy as it is specified by the programmer. Those who compile their AmigaBASIC programs can benefit gready from creating batch files under program control.
A program that creates the batch files that it needs would become completely independent; instead of ARCing 2 files (the program and die batch file) for distribution, only one would have to be ARCed.
The final section of the program, just before the subprograms. Is used to execute the batch file CopyFiles.BAT. There are two ways to execute a batch file from AmigaBASIC. One How does IMG Scan work?
With IMG Scon you can use your dot matrix printerto scan pictures.
Simply attach the IMG Scan fiber-optic sensor to your printer, and use the IMG Scan software to digitize photographs and drawings. You can then save the picture in standard IFF format for use with your paint, desktop publishing and video programs.
Which Printers will IMG Scan work with?
IMG Scan will work with any dot matrix printer that has adjustable vertical line spacing and a print head which moves across the carriage. This includes such printers as Epson, Panasonic, Citizen, Citoh, Star and most compatible printers.

One of die slogans I recall from high-school physics is that “Starting friction is greater than moving friction."
This certainly is the case with the 5.0 compiler. Take, for instance, die use of precompiled headers. They are mentioned in the Preface as a way to speed up compilation, but otherwise the Master Index is unhelpful.
Reading through the options for the LC command, you will find one switch, -ph, that will generate precompiled headers, and anodter, -H, drat uses them. Still it may be unclear how to best take advantage of this feature. Keep searching; eventually an item in die Upgrade Guidelines will provide the missing ciue.
Put all the include files used by all your modules in a single file with a dummy routine: include cflrst include files lnclude clast include file void dummyOl) Circle 139 on Reader Service card.
Compile this dummy program widi the -ph option of LC to produce a Q file containing ail the symbol information in those include files. Now', instead of looking through all the include files every time you recompile your program, that informadon is provided in a single file referenced dirough the -PI option.
Since version 4.0, Lattice has provided “compacted” versions of the header files that significandy reduce file size at the cost of ASCII intelligibility.
With 5.0’s ability to precompile the specific headers your program needs, you have the advantage of speedy access without sacrificing the readability of the includes.
Prototyping A number of advantages of die Lattice 5.0 compiler derive from using prototypes (declarations tiiat specify* what parameters of what kinds each function expects). For example; long RecdCBPTR file, char 'buffer, long length); If you look up prototype in the Master Index, you will again be disappointed. Here are some things they can do for you.
The first benefit is error checking.
The compiler will catch calls that use the wrong number or kinds of parameters.
These types of mistakes have bitten me often in the past with C, and I’m sure I’m not alone.
A second benefit comes from using prototypes with “pragma statements.
Once again, Lattice’s “official" documentation is a bit frustrating. However, you will find a discussion of why and how to use pragmas, plus a wealth of odrer information, in a supplementary file called ADDENDUM.DOC. The most direct way to take advantage of this capability' is using the “proto” include files. These contain prototypes of die system routines (like Read, etc.), plus corresponding pragma statements: pragma libcall DOSBase Read 2a 32103 This tells die compiler that the Read function is available at a -0x002a offset from DOSBase library' pointer.
The funny number at the end encrypts the information stating that the input parameters are in D3, D2, and Dl, the output parameter is DO, and diat there are 3 input parameters. You need not worry about these details for system calls, because die proto includes provide it for you. Once included, die prototypes plus the pragmas enable the compiler to simplify system calls.
Ordinarily, all parameters get pushed on the stack for a call to an intermediate routine in AMIGA.L1B that takes them back off and puts them in the appropriate registers. But now die parameters will be put direcdy into the proper registers and you will bypass AMIGA.LIB, saving both time and space.
You can use this approach for your own libraries as well. Lattice recently released information on BIX and PeopleLink about some of the more advanced features, and hopefully it will show up soon in their official documentation. A program called FD2PRAGiMA is provided to simplify the construction of pragma statements.
A third benefit of prototyping comes from using it with the -rr option.
This causes prototyped routines in your own code to be called using registers, instead of with the usual stack conventions. Here again, there is the potential for faster and smaller code (but see the discussion of optimization below).
New keywords Lattice 5-0 implements a number of powerful keywords for controlling the character of variables and routines.
Details on their usage are found in ADDENDUM.DOC. With __chip you can determine the kind of memory allocated for variables. For example; extern char chip buf(BUFLEN]; And with near and far ( huge) you can determine whedier 16 or 32-bit addressing will be used for external data items: extern Int _near 'ptr; There are also powerful keywords for functions. With the regargs keyword you can do on a routine-by- routine basis what -rr does for your code as a whole. That is, providing you have specified a prototype, it will cause a function to be called with rcgisterized parameters: void _regargs
somefunctchar 'a, long b); void _regargs somefuncCchar *a, long b); 1 Or you can use stdargs to guarantee the normal stack conventions for a particular routine, even though you compile with -rr. Even more interesting is the asm keyword. In conjunction with keywords for each of the 68000 registers ( aO to d7), you can determine exactly which parameter gets sent to which register.
For example: long asm foo(char register aO 'ptr); long „asm fooCchar register _a0 'ptr): 1 This is potentially very useful for specifying registerized interfaces for your own assembler routines.
I say' “potentially" because currently there is a bug in asm. If you use something other than the Amiga scratch registers (A0-A1 D0-D1) there is no guarantee that the calling routine will save them first. However, by die time you read this, that bug may have been fixed. .'Also, do not use the -cr option because it is incompatible with the use of asm.
Global optimization We have already seen a number of provisions for optimizing code making it smaller, quicker, or both. This includes LPROF & LSTAT, the use of pragmas with library' calls, and -rr and regargs for further registerizing. Indeed, in one respect Lattice seems to have “over optimized": their 32-bit divide routine CDX33 no longer checks for divide by zero.
Still, diis is a powerful and impressive array of optimization tools. It is topped off with a global optimizer, GO, diat can reduce program size by over 10%, with commensurate speed advantages. GO has some nice capabilities, though there are ways in which it might be improved. It does not replace a good assembly language programmer, but it writes pretty decent code for a machine.
The optimizer is available in LC via switch -O. The first tiling you will notice when using it is that it catches “dead assignments” at die symbolic C level and eliminates them. The second thing y'ou will notice is diat compiles can tzke a lot longer up to four times longer in some cases. To avoid this penalty, you can defer opumizudon until you have odierwise refined and debugged your software.
GO does some nice diings. It tries to make sure the most frequently' used parameters and variables are put in registers, and it favors register over memory' operations. Loop construction is simplified, and index variables arc sometimes entirely eliminated (folded into increments, offsets, and displacements).
One of die bugs 1 found reveals just how clever some of these optimizations can be. The subtraction of a constant from an array index was eliminated, transformed instead into a register offset value. However, because that constant was so large, when it was muldplied by the array size it resulted in a value that overflowed the 16-bit displacement.
There are ways in which GO might be improved. The first optimizing compiler I ever encountered was for Pascal, of all things. It Impressed me by recognizing that if a mod of two values (in C, a % b) was followed by' a div (a
b) , the divide routine need only be called once. GO does not yet
have diis trick.
If you look at code generated by the optimizer, you will see that sometimes it insists oil register operations even when this wastes steps. Though dead assignments are caught at the symbolic level; diey are often overlooked at the register level. Loop construction could lie further improved by moving the initialization of constants outside the loop.
Finally, using D0-D1 A0-A1 as scratch registers sometimes conflicts with using them with -rr or regargs for passing parameters in subroutine calls. In one example, the called routine pushed otiier registers on the stack, and unloaded the scratch registers into them before proceeding. Combined with the use of LINK and UNIX even when no local storage is necessary, die advantage of registerized parameters can be lost.
Way is to use the xOpen function to open an input path from the batch file and use that as tire input path for the Execute function, such as in£=xOpen£( SADD("CopyFiles.3A7"+CHR$ (0) ] x=2xe:uteM SADD (CHR$ (0)), ir.L, outfi)
1005) However, there doesn't seem to be any way of passing
parameters using this method. So, in this program we use
the dos library’s Execute function to execute the AmigaDOS
EXECUTE command. In other words, we are executing the batch
file from AmigaBASIC as if we were executing it from the
CLI, A command string in an Execute function, such as
"Execute CopyFi.les.3AT RAD:c rairuc ra:n: Copy. Lis
e''+CHK$ (0) would have the same effect as typing die
following from die CLI: 1 Execute CopyFiles.BAT RAD:c
ram:e ram:Copy.List One final note: when you use Lhe xOpen
function, it is important that you execute the xClose
subprogram before exiting the program. Each time the
program is executed, AmigaDOS gives the xOpen function a
new handle. This means if you stop the program before the
output path is closed, make changes to the program, then
rerun the program, you WILL NOT be able to close the
previous output path.
Because the handle is stored in an AmigaBASIC variable, it is initialized the next time the program is run. Doing this several times produces several open output paths (which take up precious memory ) that cannot be closed. These paths will remain open until the Amiga is rebooted. Someone may say, “I don't care, I have eight megabytes! I have plenty of memory to spare!” Well, there is one more side effect of leaving those output paths open that will become apparent in a moment.
Debugging hints Before diving into a new and ambitious programming project using these techniques, there is one thing a programmer should keep in mind. Since most of the library operations in a program of this type rake place behind the scenes, debugging can be extremely frustrating. However, there are a few simple things that can be done to help the bewildered programmer.
First of all, if a program seems to have skipped operations in die batch file or has performed them incorrectly, review the contents of the batch file. Misspelling an AmigaDOS command will cause that particular operation to fail, making it appear as though the operation has been skipped. .Also, check for proper pathnames. If die batch file contains a command such as DELETE ram: filenairie then be certain that the name of die file in filename is not preceded by a colon. Otherwise, die .Amiga would execute die above command as DELETE ran::filename Once die batch file has been given a clean bill
of health, die call to the dos library’s Execute function within the AmigaBASIC program should be attacked. The best way to distinguish between a flaw in die batch file and a flaw in the program is to execute die batch file from the CLI, inserting the predicted parameter values into the command string. If the file works, die Use A2000 Cards With Your Amiga 500 or 1000.

Problem is within the program. The most likely suspect, in this case, would be the punctuation in the call statement. One small mistake in punctuation could possibly prevent all parameters from being passed, crippling the operations of a batch file.
Another way to debug this type of program is to monitor the progress of die batch file. Any failures by an AmigaDOS command in a batch file are reported in a brief message that is sent to the specified output path. Unfortunately, the output path normally used for this operation is NIL:, which cannot be seen. However, NIL: may be replaced by CON:. CON: is the AmigaDOS window device that can be used by the xOpen function to open a visual output window. Error messages may then be read from this window as they are created.
Opening a small output window at the bottom of the screen could be accomplished by the following statement: outi=xOpens(SADD("CON:0 150 640 50 Debug Window"+nS), 1006) This statement would open an output path to an .AmigaDOS output window appearing flush to die left of the screen, with its top beginning at the 150th pixel (3 4 of the way down the screen). It would have a width of 640 pixels, a height of 50 pbcels, and an optional title, Debug Window, in the titlebar.
Anv error messages created by a batch file would show up in Debug Window. However, the next PRINT statement would force AniigaBASIC's current output window to die front, hiding the newly created Debug Window. The AmigaBASIC output window, therefore, should be resized to reveal the AmigaDOS output window.
Caution should be taken when using an AmigaDOS CON: window for debugging. As mentioned earlier, failing to close an output padi before exiting or restarting a program can render portions of die Amiga's memory unusable to other software applications. With die addition of die CON: device, screen space is also sacrificed. Moreover, if enough of diese pesky'windows are accumulated, there could be a significant lag in window and screen updates. Regrettably, the only solution to this sort of dilemma is to save anything of value residing in RAM and reboot die machine.
With a litde practice and experimentation, the programming techniques described here can open a multitude of doors for the .AmigaBASIC programmer. Since any AmigaDOS command may be executed using the Execute function, a personalized directory utility program might be an appealing project for a few thrill-seeking souls. Don’t be afraid to try something new it just may work.

Alert: Using System Alerts from BASIC by John F. Wiederhim In
the first part of this series, we discussed using requesters
from BASIC and provided a set of routines which allowed BASIC
programmers to set up and call the system requester routines
from within BASIC. In this article, we will move a step
further and provide another type of system message callable
Scenario: your home budget program is almost complete.
You've used the system requesters to fine tune your user interface to a new level of fk-and-finish. Still, something seems to be missing. There are times when you really need to get the user’s attention like when they are about to do something that will have catastrophic results, or when the program realizes it has a problem, and you want to tell tire user to cut their losses and save their files before everything falls apart.
Somehow, using a requester box for these messages is just too ...nice. There are times when you need to make an impression on the user. Make them turn their attention from a background program. With a requester box, users can continue working on other items, ignoring the message until they are ready to deal with it. However, the next message the user receives could very well be "Software error - task held” or, even worse, a visit by die Guru himself. We need a message which preempts everything else, and forces the user to respond.
The Guru is a nifty way the system has of immediately getting user attention (not that it really matters at that point).
Wouldn’t it be nice if you could put up custom “alert” boxes with your own message inside? Just the sight of the flashing red box is enough to get anyone’s attention. To top it all off, die system would also preempt other activity, and disable the mouse pointer as well. The best part is that die system uses a routine to do this which we can adjust to suit our own needs.
Not only is it possible but, once you understand the mechanism, it is actually sort of easy.
Once again we will use AmigaBASIC's built-in extensibility through die DECLARE FUNCTION...LIBRARY constructs to "hook” onto the necessary system rouiines, making them available for use in BASIC as “regular" commands and funcdons, and each of them wall be discussed in die next section. Some of diese may look familiar, as we used a couple of them last time in the requester program, and I wall only briefly recap diose, while the new routines will be covered in detail.
Both of the programs listed here use the BASIC command LIBRARY to open die Intuition and Exec libraries. To do this from BASIC, you need to have the “intuition.bmap” and “exec.bmap” files, eidier in die current directory when the program is run, or the libs: directory of your Workbench disk. If you are missing eidier of die .bmap flies needed, you can make them using die “ConvertFD” BASIC program found on your Workbench Extras disk. For more information on .bmap files, and the “ConvertFD” program, consult the AmigaBASIC manual.
Type in the demonstration programs. The first is a sample use of the alert routines, which puts a customized alert on the screen, and reads the user's response. The second is a more elaborate demonstration covering the use of both requesters and alerts from widiin die same program. It attempts to mimic the requesters and alerts associated with a system crash, but finishes leaving the system unharmed, and in die same “condition” as before it was run. Once die programs have been individually typed in, SAVE THEM! These programs use certain routines which can easily crash the system if there is
even a minor typo in their code. Should that happen, if the program wasn’t saved, chances are you're going to have to type in die entire program again.
Once the programs have been entered and saved, run each one several times. Both programs must be run in 80- column mode, this allows die text in die alerts and requesters come out properly aligned. Set preferences accordingly. Get to know how it “feels” to use die alerts. Then when you are ready, finish the article and pay particular attention to the information covering the new' routines and the line-by-line explanations of the programs. The BASIC subprograms were designed to be modular, and once you understand their operation, feel free to include them in your owrn programs, modifying them
to your needs.
“Old” system routines Those of you who are familiar with the operation of the AllocMem, FreeMem, and CopyMem routines (from die previous article, or similar experience) may wish to skip ahead to die next section on the new routines used, as I am going to briefly review operation and calling methods for these routines from BASIC. One important note to die readers of the previous article: When I explained how to call FreeMem and CopyMem from BASIC 1 declared diem as functions, and used “dummy” variables to make them w’ork properly, This was so the programmer reading the article could easily
see that these were system routines called from a library. However, although the previous method w'orks fine. I am switching to a more “standard’' method, assuming the reader is aw are that these are system library routines. Most notably, diey are called using the CALL command, and are treated as subprograms rather than functions. This is because diey do not actually return a value to the calling program. The “type extender" (&) must still be left at die end of their names w'hen declared and called. From now on, when these routines are called. This is the method I will use.
To call die system routine used to generate alerts, a number of pieces of information must be supplied. One of these is a formatted string containing the message to be displayed in the alert. While die formatting of that string, and the other parameters will be discussed in the section on the new.- routine, there are otiier routines which are used to provide the routine widi the information in the proper manner.
AmigaBASIC has a tendency to move the actual location of string variables' data around in memory for efficiency reasons.
While this causes no problem in BASIC, the system routines we are using need to know the address of where the data being passed to them is located. For this reason, we can't just hand them die string variable itself. Instead, we must set aside a block of memory7 which will not be moved by BASIC, and put the string data in that block. We could just arbitrarily choose a block of memory, but because we don’t really know what areas of memory are safe to modify and use, this approach could easily result in system crashes. Instead we use the system's AllocMem routine to find a block which we can
use. Do this by giving it the size of the block we need (in by7tes). This block is guaranteed to be both safe to use, and safe from use by other programs. Declared like other system functions, and found in die Exec library, the AllocMem routine is called from BASIC like diis: Wouldn’t it be nice if you could put up custom “alert” boxes with your own message inside? Just the sight of the Hashing red box is enough to get anyone’s attention.
Address& = AllocMem&( size , type ) The size variable tells AllocMem how many blocks we need, and the type& variable tells it what kind of memory is needed (in our case, we set type to 65537 which tells AllocMem to give us whatever kind is available, and to "clear” the block before giving it to us). AllocMem dien returns either die address of the block or a zero in the address variable. If it returns a zero, it couldn’t allocate a block die size we need. For us this usually means die system is so messed up that we should tell the user to reboot and try7 again.
Once we have the address of the memory we will store the data in, we use die CopyMem routine to quickly copy the data from the string variable into the "safe” memory block.
CopyMem is in die Exec library7, and it is not a function, so we do not have to DECLARE FUNCTION...LIBRARY it, but instead just need to open die Exec using LIBRARY “exec.library". To call CopyMem from BASIC use this code: CALL CopyMem&( sources, destinations*, size ) Source& is the address where the data is to be copied from (in this case the string variable), destination is address where die data is going (our “safe” memory7 block), and size is the number of bytes to be copied. Using this routine is MUCH faster than doing the same diing with a loop in BASIC, Finally, once we are done using
the allocated block of memory, we need to tell the system it can use it again. Otherwise, it has no way of regaining access of the block short of rebooting, and the amount of free memory would go down every7 time the program was run. Tell the system an allocated block of memory is available for use again by calling the FreeMem roudne from the Exec library. This routine is like CopyMem in that it does not need to be declared to be used.
We just open Exec and call it like this: CALL FreeMem&( address&, size&) Address is the address of the block wre received from .AllocMem, and size is die number of bytes we allocated. As stated in the previous article, FreeMem is a potentially' dangerous routine to use. You MUST give it die exact address reaimed to you by' a call to AllocMem, and you must give the exact number of bytes allocated in the block. If either of these values is in error, a sy'stem crash is virtually certain.
Those are the "old” routines which we use in this program. Note that the calling subroutines to allocate and free the memory’ blocks have been changed for alerts, reflecting die different formatting of alerts as opposed to requesters. Now onto the new stuff... The DisplayAlert Routine The routine that the system uses to display those Gum Meditation alerts you most likely have seen is called (appropriately) DisplayAlert. It is declared for BASIC as follows: DECLARE FUNCTION DisplayAlert%() LIBRARY This tells BASIC that DisplayAlert is a system function found in one of the libraries, and
when it is called, it returns a short integer value (lienee the % after DisplayAlert). It is found in the Intuition library which is opened from BASIC using: UBRARY 'intuition.library" Once Intuition is open, the DisplayAlert function can be called like odier system functions by using this code: response% = DisplayA!ert%( type&, address . Height&) Type will always be set to 0 for us, which tells the system we want a recoverable alert, and want die result returned to us. According to the ROM Kernal Manual: Libraries and Devices (one of the Amiga system programmer’s holy books) allows the
possibility that if the system is in bad enougli shape, die alert may be automatically upgraded to non- recoverable status (DeadEnd in RKM parlance). This is just a warning of a remote possibility however, and I have a feeling diat BASIC would crash itself before the system got that messed up. I have never had an alert get upgraded, but just in case one does, now you know why.
Height is the number of pixels it will take to contain the entire vertical height of the alert. This is a number which I had to fine tune a little bit to get the results I wanted, but so far the following formula seems to work: MASTERPIECE PROFESSIONAL FONT COLLECTION® 20 DISK SET The largest collection of fonts and clip art available in a single package for the AMIGA.

Heights = 8 + (10 ‘ number of lines of text in alert) This seems to give enough vertical room for the alert without spacing things out too much. When the programs are explained.
I’ll point out where this is calculated so that you can change it to your own preferences. Be forewarned, you can generate some pretty' strange displays if height& isn't large enough, or is too large.
Nowr things start to get complicated. The address& parameter is the address of a block of memory which contains specially formatted data representing the text of the alert, line by line. This text is not in the IntuiText format used by requesters and most other Intuition routines, but instead is in a custom format used only for alert messages. The data is composed of a number of sequential substrings, one for each line (or section) of the alert text. Each substring has the following format: Field Type Contents Xpos Short integer X position (pixe s) of substring text.
Y Pos Byte Y position (pixels) of substring text.
Text ASCII data Null-terminated string of characters, More?
Byte 0 = No further substrings.
1 = More substrings follow.
The X Pos and Y Pos fields tell die DisplayAlert routine where each substring’s text should be located relative to the upper left corner of the alert. These values can be used to locate pieces of text anywhere inside the alert. Note that a Y position larger titan the heightSt passed to DisplayAlert can have unpredictable results, and probably should be avoided. The same is true of an X Pos larger titan the current width of the screen (320 in lo-res, 640 in Iti-res).
The Text field contains the ASCII text of the substring text, and is ended with a CHRS(0) (also known as NULL), hence null- terminated. Each substring text can be no longer than the distance in characters from X Pos to die edge of the screen or more strangeness can result. Usually die text wraps around to the start of the same line, but may have other more serious effects.
The More? Field tells DisplayAlert if there are any more substrings, thus allow'ing multi-line alerts and die like by setting all the substrings’ More? Fields to 1 except for die last one. Pretty straight-forward.
Once die text data is properly formatted, the address of die formatted data is then given to the DisplayAlert routine in its address& parameter. Again be careful, as errors in formatting can cause system lock-ups and crashes.
Finally, the user response is returned in whatever short integer variable has been assigned to receive it. Like response% in die code above. The user response is either a 0 indicating die right mouse button was pressed, or a I which means the left button w-as pressed. By analyzing the response, the program can give two choices in the alert and get a selection, just like requester boxes.
When die alert is generated, unlike requester boxes, a couple of tilings happen: The entire display is shifted down far enough to display the alert inside a flashing red box, and the system is pul on hold until the user responds to the alert. This holding of all other system tasks is both useful and problematical. The user has no choice but to respond to the alert, since nothing else can be done until the alert ends. However, I cannot guarantee that holding die system tasks won’t cause problems when other programs are running at die same time.
One big if would be the effect of alerts on system disk functions called by other programs. The moral is that you must use this routine sparingly, and should check how the programs you use it in affect other system programs. However, BASIC is a processor hog, as evidenced by the slow-down in screen updates while it is operating, tha: most of the time, BASIC will be the only tiling a person runs. The DisplayAlert routine is no problem inside BASIC, and indeed, BASIC even uses it for some special error conditions (Out of Pleap Space, for one). One other effect of DisplayAlert is that for the
duration of the alert, die mouse pointer is shut off. This has to do with the holding of system functions, and die shifting down of the display. A funny side-effect of die mouse pointer change occurs when the pointer is very near or in the menu bar at die top of the screen when the alert occurs. The alert is displayed, and the pointer is disabled, but die alert show's up with a red vertical bar running from the top of the alert all the way dow-n through die display.
This bar disappears when die alert finishes, and seems to do nothing more than mangle the alert. When the alert is complete, die display is shifted back up, the pointer reappears, and everything goes back to normal.
Now' diat the DisplayAlert routine's function is understood, we’ll go through the execution line-by-line for each of the programs.
The Sample Alert Program Let’s take a look at die first program. Ail this program does is set-up the parameters, and call DisplayAlert, but does so using some modular BASIC subprograms, which can be used in 200 Armstrong Road Las Cruces, NM 88001 BBS: 505-523-4405 24 Hours Day Voice: 505-526-6243 M-F 8AM-5PM MST Accolade Jack Nickalaus Golf... .28.50 Fast Break . ,.25.50 Antic Software GFA Basic . ,78.95 Phasar ..50.50 Zoetrope Anim Sys.... ..78.95 ASDG Dual Ser Port ......

Any program to display alerts. By tire way. I really do apologize for the joke, but I needed some sample text for the alert, so... We'll take dais program from die top.
CLS DIM xp%(4).m$ (4) At the start of the program, we clear the screen, and dimension two arrays which we will use later to hold the X Pos field, and text for each substring used in the alert.
DECLARE FUNCTION AilOCMem&O LIBRARY DECLARE FUNCTION DispIayAlerffcO LIBRARY LIBRARY “exec.library" LIBRARY "Intuition.lib'ary" Next, we declare die AllocMem and DisplayAlert system functions, and open the proper system libraries. Again, remember that aldiough we also use the CopyMem and FreeMein routines, they need not be declared when used as subprograms, not functions.
PRINT "This Is an example of using the DisplayAlert system" PRINT "routine to make an alert, and get the user's press" PRINT "of either a left or right mouse button," PRINT We then display a brief message telling the user what’s going to happen next, so die disk access which follows won't surprise anyone, so die user won't see flashing red and think die system crashed.
FOR 1% = 1 TO 4 READ m$ (i%) wx% = INTC(640-CLEN(mS(i%))'8)) 2) xp%(i%) = wx% NEXT 1% r% = 0 Finally, before calling die ALERT subprogram from die main program, we read die text for die alert from die data statements at die end of the main program, use die length of each string read to compute the proper X Pos for each substring in the alert. This is put in the xp%0 array. Also, die r% variable which will contain die user's response is cleared.
ALERT m$ 0. Xp%CL r% SUB ALERT (messSO. Xpos%0, resp%) STATIC Here is the important call, from the main BASIC program to the ALERT BASIC subprogram, which does everything to put up the alert, and returns the user response in its resp% variable (r% in die main program for us). The ALERT routine takes three variable names, two for input, and one for returning the user response to the main program, The messSO array holds the text for eacli line of the alert, while the xpos%0 array holds die x- offset for each line.
Nlines% = UBOUNDf messS) aHgt& = 8 + (10 ' nlines%) mS = ““ Inside .ALERT, the nlines% variable is set to the number of elements in the messSO anay, which corresponds to the number of lines in die alert. AHgt& is set to the overall height of die alert which will be passed to DisplayAlert. Note the formula which I mentioned earlier can be adjusted to suit your needs. The mS variable is cleared, preparing it as die string which will hold die formatted data describing the alert text, prior to it being copied into allocated memory.
FOR y% = 1 TO nlines% Now a loop is started which will go dirougli each line of text in the messSO array.
V kS = messS(y%) wkx% = xpos%(y%) wky% = 10 ' y% Wk$ is set to the text of die line being formatted, while wkx% and wky% are set to die x and y-offsets of each line. We set wkx% out of the xpos%0 array, and can just calculate wky% based on the line being formatted.
CALL FormatA!ert( wkx%. Wky%, wk$ ) SUB FormatAlert( x%. Y%, msgS) STATIC The FonnatAlert subprogram is then called with the x- and y- offsets for each line in wkx% and wky%, and the text for the line in wkS. Inside the ForniatAlert subprogram die offsets are called x% and y%, and the text is in msgS, Note that die program returns the formatted substring data in die msgS variable, which means wk$ for the ALERT subprogram.
IF (x% 0 OR x% 320) OR (y% 0 OR y% 200) THEN PRINT" Format location error. Check X Y coord."
STOP ENDIF xm% = lNTCx% 256) xl% = x% MOD 256 xyS = CHRS(xm7o)+CHRS(xi%)+CHRS(y%) Inside FormatAlert now, the x- and y-offsets (in x% and y%) are checked to make sure they are within display boundaries, and if not, then an error message is displayed, and die program halted.
If the offsets are okay, x% is broken into its individual bytes, and a three-character string is constructed from the two bytes of die x% offset, and die single byte of the y% offset.
IF LEN(msg$ ) 80 THEN PRINT" Format line length too long. Check msgS."
STOP ENDIF The msgS text is checked to make sure it doesn't exceed one screen line in length, and if it does, an error message is printed, and the program stops. This does NOT make sure chat starting from the x-offset of the line, that die entire line fits on the display, so you must still check that yourself.
A$ = xyS + msgS + CHRS(O) msgS = a$ END SUB Wrapping up FormatAlert, aS is formed by appending die msgS text to the offset data in xy$ , and a CHR$ (0) is put on die end of the text to make it null-temiinating. The newly formatted data is then returned in msgS.
IF y% nlines% THEN wkS = wkS + CHRS(l) ELSE wkS = wk$ + CHRS(O) ENDIF m$ = m$ + wkS NEXT y% Back out to ALERT’, the formatted substring is made complete by appending either a CHR$ (1) if more lines follow, or a CHSSCO) if this is the last line (as per die More? Field of a Display Alert message substring). Each of the substrings is added to m$ so that when the loop is done, m$ contains the entire formatted message string data for DisplayAlert.
CALL MkAlert( mS, mAdd&, mSiz&) SUB MkAlert( msgS, Addr&, Size&) STATIC Next, m$ is passed to the MkAiert subprogram. The MkAlert subprogram takes a formatted alert message string, in msg$ , and returns the size (in Size&) and address (in Addr&) of the memory block used to store the message data.
S!ze& = LENC msgS) Inside MkAlert, Size& is set to the number of characters in msgS which is the same as the number of bytes needed to store the data in msgS.

STOP ENDIF Preparing to call the AllocMem function, we set memtype& to 65537, and set mAddr& to 0 & assuring us that we can tell if AllocMem doesn’t return an address. AllocMem is called, and the address of a block Size& bytes long is put in mAddr& (hopefully). If mAddr& is still zero, then AllocMem couldn't get tine block, so we print an error message and stop.

AHgt&. Assuming everything is set up properly, DisplayAlert then returns die user response in resp%. That’s all there is to calling an alert. Now jVLERT just has some cleaning up to do.
CALL FreeMem&( mAdd&, mSiz&) ALERT calls the system routine FreeMem, giving it die address and size of the memory block allocated to hold the alert message data. ALERT'S done with it, so it gives it back to the system.
END SUB That’s the end of ALERT. Control is passed, back to the main program, with the user's response in resp%.
PRINT "The user pressed the IF r% = 1 THEN PRINT "LEFT mouse button," ELSE PRINT "RIGHTmouse button.” END IF The main program is almost done. The user’s response is checked, and depending on whether the user pressed the left or right mouse button, die appropriate message is displayed.
LIBRARY CLOSE END The main program then doses the libraries it opened, and finishes execution. By die way, those data statements between LIBRARY CLOSE and END just hold die text for each line of die alert.
That's it. Look through die program, play with the code, and get to understand how it works. Then feci free to use the subprograms in your own code, providing needed adjustments.
Alerts can be very useful to get messages across dial you want to make sure the user notices. Try to resist the urge to use alerts for non-critical messages however, because they do disrupt normal system functions, and like anything else, using them too much will make the user start treating them like regular messages and pretty' much ignoring them.
The last section of this article briefly explains the operation of die second program, which takes parts of this and the previous article, and uses them to create a fake system crash.
11) e System Request Program Right off the bat, let me explain
the name. When you load and run a BASIC program, the output
window is tided die same as the program's file name. To save
a little code, but keep the requester looking authentic, this
program must be saved as “System Request”, so the output
window has that tide when the program is run. This is a
harmless litde program, but you must understand diat it only
simulates a system crash, and it is not a real crash (unless
of course you made an error when typing it in, which might
cause a REAL crash). When you press the mouse button during
the alert, it returns you to BA6IC like nothing had ever
happened. Type it in, save it as “System Request” and run it.
Below I’ll quickly explain how the program works, but except
for the main BASIC program, I am only going to note changes
in the subprograms from this and the last article, since they
work die same as described before.
CLS DIM xp%(3), mS(3) Use the same start as the alert program, but note that since we will be using only three lines, xp%0 and m$ 0 must only be dimensioned for three elements. Later we will use U BOUND to figure out how many lines of text there are in die alert. The next few lines will declare the system funcdons, and open die necessary' libraries. Since we will be using requesters and an alert, we need AutoRequest, as well as. DisplayAlert.
MS(l) = “Software Failure. "+SPACESC8) mS(l) = m$ (l) + "Press left mouse button to continue."
MS(2) = * ’ mS(3) = "Guru Meditation 00000006.0001 F688" FOR i% = 1 TO 3 j% = LENC mS(i%)) wx% = INT((640-0%*8)) 2) xp%(i%) = wx% NEXT % fk-Q Here we use a slightly different mediod to set up m$ 0 with the alert message, and calculate the values for xp%0. The end result is still the same, with m$ 0 holding the alert text, and xp%0 holding the x-offsets for each line. After this, die next lines set up the message for the requester box using the same method we used in die last article.
(continued on page 98) The Intruder Alert (IA) is a hardware software package that turns your Amiga into a security guard. The IA connects to the Amiga through the joystick port *2. It has eight RCA jacks in the back that you connect to the real world. The ports can be connected to any on off or open close type switch capable of handling TTL (0-5 Voles) at 100 milliampere. You can even connect a X-10 Powerhouse Computer Interface and turn electrical appliances (lamp, TV, radio, tape recorder, etc.) on and off.
The software included with IA is easy to use and bug-free.
There are three different screens: control, setting, and reading.
You can call the computer, and the computer will answer (or not answer if you so choose) when there is a breach. There are also settings for how long IA will wait before monitoring, how long before a breach is signalled, how long the alarm will sound, how long before lire port is reset, and how long before IA will stop monitoring. These can be set for each port separately.
The reading pane! Shows statistics concerning each port: on or off, total number of breaches, and the total time the port was breached. There is also a timer displaying tire totai length of time that LA has been monitoring.
Your Amiga On Guard Intruder Alert revieiv by Mike Morrison The control panel is the first screen you see wrhen the program is run. From here, you have a multitude of options regarding how EA will monitor its ports: whether a breach occurs wrhen a port is opened or closed, whether you want sound and voice alarms on or off, whether you want program “hooks” and breach recordings on or off, how many times a “hook" or breach should be recorded, and whether breaches shoutd be written to a disk file. You can push the monitor screen to the background, save current settings, and select a setup file.
The setting panel lets you choose what alarm will sound when a breach occurs for each port. You can select one of four digitized sounds (three different alarm sounds and a dog barking) to play when a breach occurs. You can also select up to four lines of text (up to 37 characters each) to be spoken when a breach occurs. Although a minor complaint, I think the user should be able to use oilier digitized sounds in place of the four included.
You can also have die computer dial a number through a modem when a port is breached. When the phone is answered, IA plays tones or pulses to signal that a breach has occurred. Or At first glance, you might tli ink that eight ports is not enough, but with some creativity eight ports can stretch a long way. You can have all your windows attached to just one port by waring ( them sequentially. This would sound an alarm if any one of the windows where opened. (You w'ould not be able to tell which window it was, but the important tiling is that you know one of them is open. )The same idea could be
used for all the doors on one floor. You can also use port -8 to send signals to a X-10 interface.
The "program hook" is a very useful and versatile feature.
The hook allows you to execute a batch file each time a breach occurs. Create the batch file using your favorite editor to either modify one of the three examples supplied or to create your own. There are three examples and another that is left blank for Index of Amazing Advertisers Discover something interesting?

LIBRARY CLOSE END We finish the program by showing a message upon returning from the alert which tells the user it was all a joke, close the open system libraries and end. There are no data statements, because we did not use that method to assign the alert message to the m$ 0 array instead of assigning it directly to die array itself. There you have it. A pseudo-crash, done completely from BASIC, as a demonstration of using requesters and alerts from within BASIC programs.
The designers of AmigaBASIC may not have given programmers even' ability that programmers in a “serious” language like C have, but with a little ingenuity, and a couple of system manuals nearby, we can come close enough Furthermore, AmigaBASIC comes free with the computer, and if you really need compiled speed, you can always pick up a BASIC compiler to boost up die performance of your programs a little.
On die (gasp!) IBM, BASIC is reentering die arena as an application-development language, and gaining respect as a “serious” language in its own right. If BASIC on the IBM can be “serious”, then it’s up to us to show the C and Modula-2 snobs diat our BASIC can be “serious” as well.

The rest of DoReq functions normally, as do the subprograms called by
it, so when all diat is complete control returns to die main program. For an explanadon of DoReq’s functioning, and its related subprograms, consult die previous article.

• AO Amazing Programming Building a Better String The Amiga's
user interface presents the programmer with incalculable
possibilities and methods of capturing data. But consider for a
moment those programs which do not benefit much from colorful
gadgets, proportional knobs, sliders and all the other
frivolities of mouse-driven input.
...setting up the data entry window is not that complicated.
I’m talking, of course, about those programs in which die user is required to enter data primarily from die keyboard.
These programs are usually responsible for such mundane tasks as maintaining databases, possibly for accounts receivable customers, employees, vendors, or for tracking daily sales. The information required by these programs is not graphical, but textual, and can only be acquired by some hapless individual spending hours at the keyboard entering data.
The typical user of a keyboard-oriented task is not likely to be impressed by a fancy gadget rendered in 4096 different colors. Rather, diey are going to be more concerned with the speed with which they can process their work. Unfortunately, these same risers must he wined and dined by Amiga software developers if die machine is ever going to be taken seriously in die ever-growing (and lucrative) business world.
The competition Developers who create keyboard-oriented applications on IBM PC’s have it made. These guys have got data entry screens down to a science because they’ve had to get by for so long without the benefit of a mouse-driven operating system.
PC’s such credibility and formidability in the computer world.
Keyboard input on the Amiga As an aspiring Amiga software developer, you are faced with die following situation: You must write a program that keeps track of, among other things, accounts receivable customers. You need the following information from the user: a customer number; the date the account was created; his last name; first name; address; city, state and zip; and phone number.
From a programming standpoint, setting up die data entry window is not diat complicated. We need a window and seven string gadgets. But diink about what the end user will have to do to enter this information. Assuming you are kind enough to activate the first string gadget for him, die user will have to type in the customer number, take his hand from the keyboard, put it on the mouse, move the mouse to the entry date field, click the button, remove his hand from die mouse, place his hand back on the keyboard (hopefully landing on the right keys), and type in the date. The user will have to
repeat this for each of the remaining input fields on the screen.
Trivial, you say? True, if you have only two or three string gadgets on the screen, the user will probably not utter too many curses at you. Make the user move his hand between keyboard and mouse too many times, though, and your program disk will very quickly be convened into a blank, formatted floppy.
Kidding aside, entering data would be much faster if users were not required to remove their hands from die keyboard.
If you're skeptical, set up a window with at least the input fields mentioned above, and try it yourself. Consider also diat this is an extremely simplified example. A real-life accounts receivable program would have to keep track of finance charges on each account (month and year-to-date), past due balances (31 to 60, 61 to 90, and over 90 days), possibly month and year- to-date charges and payments, and several hundred (yes, HUNDRED) individual line items for a plediora of accounts, very likely reaching into die hundreds as well.
At a minimum, you need a way to enable users to move front one input field to another quickly, without moving their hands from die keyboard.
Luckily, Intuition does provide a fairly easy way to extend its data structures so diat they include any variables pertinent to the application at hand. In our case, die door to expansion will be die UserData field of die gadget structure. We can define a new data structure diat will enable us to bounce from input field to input field using the keyboard and tack a pointer to the new structure onto the end of each string gadget.
We will need to store at least four pieces of information in the new data structure. Specifically, these are four pointer fields which will tell us which gadgets to move to when the user hits die up, down, left, or right arrow keys. If any of these fields contains a NULL value, the gadget currently highlighted will remain highlighted when die corresponding arrow key is hit.
We will need to draw a border around the currently active gadget so users will know which input field diey are sitting on.
Because we will be highlighting each string gadget “on-the-fiy," tiiere will be no need to store a Border in the string gadget itself. This brings up die next items we will need in our data structure die foreground and background colors, and a pointer to the gadget's window to get to the correct RastPort.
The remaining field in the structure will tell us when the More than just a Hard Disk Backup Utility py Rapidly copies directories and files to floppy disk C A FF l*ler Hari Disk Backup Programs this fast create NON standard disks ijLH i l"ii can only be used by their program.

Gadget is selected. This field is necessary because we still want the user to be able to select the gadget with the mouse, and some special processing is needed in this case. Refer to Listing One to see the complete data structure, which I’ve called STRNODE.
The system will work in the following way. The user wall be able to higlilight a string gadget using the arrow keys to move to the desired input field. When the user is at the field where he wants to enter data, he will activate the string gadget by striking the RETURN key. When tire user finishes entering data into the string gadget, they will press RETURN again, At this point, the user may use the arrowr keys to move to the next gadget or they may still select string gadgets with the mouse. In this case, the highlight box around the current gadget is erased, and the gadget hit by the mouse
is highlighted and immediately activated (a cursor appears and the user may enter data).
Highlighting and activating the gadget must be triggered by two seperate events because once the string gadget is activated, it is impossible to monitor keyboard activity without going through some rather ugly contortions. If we activated a gadget as soon as it became highlighted, we would be assuming that, because the user higlilighted the gadget, he wants to enter data there as welJ. This might not always be the case; the currendy highlighted gadget might simply lie along die path to the user’s true destination. Activating each gadget as it Ls highlighted would cause nearly as much trouble
as having to select it widi die mouse!
Only a few simple functions are needed to implement diis system. Please refer to Listing Two, for these routines.
It might be helpful for you to lay out your input screen on paper before calling any of die setup routines. After putting things on paper, you will have a dearer perspective on which gadgets should be highlighted when the appropriate arrow key is pressed.
When your screen is ready, you can call the function SetSTRNODE to set up die string gadget pointers. To this function you will pass die address of die string gadget you are initializing, four more pointers to gadgets, the foreground and background colors, and die address of die window containing your string gadgets. You will have to call SetSTRNODE from die keyboard for each string gadget you wish to highlight.
To present a consistent environment to die user, it is a good idea to call SetSTRNODE for all die suing gadgets in your display. Otherwise, when users select a gadget for which you have not called SetSTRNODE, they will be unable to use the keyboard to move to a different gadget.
Keyboard events Let’s turn our attention now to die keyboard and how we will monitor key press events from Intuition. You can elect to have Intuition send you two types of keyboard events, called RAWKEY and VAN! LI A KEY.
RAWKEY events are sent to your program once when a key is pressed, and again when the key is released. If you have ever spoken direcdy to the console device, you know that some keys on the Amiga keyboard send whole strings of characters to your program, in particular, the function keys, the arrows, the help key and all die various combinations of diese keys widi die SHIFT, ALT and CTRL keys, can result in strings of up to four characters.
Intuition deals with this by placing the RAWKEY code in the Code field of your IrituiMessage structure, and storing any modifiers, such as ALT, SHIFT or CTRL, in the Qualifier field.
These values are so-called “raw key codes", not ASCII values.
You will have to do some translating on these codes before using them to send characters to the screen in your program.
If you select VANILLAKEY events, Intuition will filter keyboard input, and only send you key codes for diose keys diat do not generate multiple character sequences. This means diat, if you are watching for VANILLAKEYs and the user hits FI, your program will not know about it because the FI key generates more than one character.
Other keys you will not hear about are the arrow keys and the help key. Furthermore, the value contained in the Code field of your LntuiMessage is an .ASCII value. So, if the user hits the “a" key, you are sent a 97 in the Code field, which is the ASCII value of diat character. You can see that, unless you define other keys besides the arrows to move die highlight box around die window, VANILLAKEY events will not work properly for this system.
Take another look at the -define statements in Listing One, stmode.h. Notice chat all but one of die raw- key codes defined there are sent when the respective key is pressed by the user. The exception is the RETURN key, which is -define'd as the “return key released" code.
An interesting tiring happens when you monitor gadget events and RAWKEY events in a window. When the user is typing text into a string gadget, your program has no control whatsoever. When users are finished typing, diey may either select a new gagdet widi the mouse, or strike the RETURN key to deactivate the string gadget.
If the user strikes the RETURN key, Intuition will eat the key-pressed event and deactivate the gadget. Once the key is pressed, though, it has to be released. Since Intuition has trapped the key press, your program will receive a RAWKEY event with tire “return key released" code in tire IntuiMessage Code field.
We are very’ interested in this special RAWKEY event because it can be used to flag the gadget as “selected” or “not selected”. This way, our two methods of selecting a string gadget the RETURN key and tire mouse will function properly together.
Since we are going to receive another RAWKEY event when the user deactivates the gadget with the return key7, we have to check the gadget to see if tire user has finished typing text, or if he is trying to activate the gadget with the RETURN key. When the function ProcessSTRNODE sees the RETURN key, it checks the gadget passed to it to find out il it is currently selected. If it is, we know tire user lias finished typing text and has deactivated the gadget by pressing RETURN, in this case, all we need to do is toggle the “selected" field of our structure back to false, and return.
If tire field is false, we know the user wants to activate the current gadget. We call the Intuition function ActivateGadget to do this, and set the “selected” field to true. Notice that it is a good idea to check the return value of ActivateGadget, since there are some circumstances when it will fail. If we set the “selected” field to true even when ActivateGadget fails, die system wiii not work properly7.
Mouse power Activating a string gadget using the mouse is just as simple. There is one trick though, and that is to remember that once a string gadget is activated, yrour program is not in control until the user deactivates it. In order to do any kind of processing before the gadget is activated by Intuition, the gadget must have the GADGIMMEDIATE activation flag set, rather than the RELVERIFY flag.
When you set IDCMP flags hi your window7, you will have to set the GADGETDOWN flag. This way, you will be notified immediately witli a GADGETDOWN message when the user clicks on a string gadget, and you can do any type of preprocessing you need. As soon as you are done, Intuition takes over and the cursor appears in the string gadget.
In our case, the preprocessing is straightforward. Whenever a GADGETDOWN is detected on a string gadget, ProcessSTRNODE will set the “selected” field to tine and immediately call DoBorder to highlight the gadget. Since ProcessSTRNODE has no way of knowing which gadget was highlighted prior to lire GADGETDOWN event, tire calling program must be responsible for erasing this gadget’s border.
The rest of ProcessSTRNODE is a piece of cake. Whenever the main program detects a RAWKEY event, it will call ProcessSTRNODE with the currently highlighted gadget Cor tire gadget hit by the mouse) and tire raw key code. If the key code is one of those defined, die switch statement will take the appropriate action. Otherwise, it just returns the same gadget that was passed to it.
For example, if ProcessSTRNODE is passed the LEFTKEY code, then the gadget's “leftkey” field will be examined, if it is not NULL, die gadget address stored diere becomes the current gadget. The border around the old gadget is then erased (by passing ’DRAW to DoBorder “not DRAW”), and a new7 Sections of a Sections of a typical Amiga print print using FinePrint (shown actual size) (shown actual size) FinePrint brings out the detail Jjg sigmlctt*
P. O. Box 419 Owego, NY 13827 Circle 118 on Reader Service card.
Border is drawn around die current gadget. ProcessSTRNODE will then pass the gadget at die “leftkey” field back to the main program, and the main program will make it the new currentiy highlighted gadget.
If the ‘ieftkey” field happened to be NULL, no action would be taken when the user hit the left arrow7 while diis gadget is highlighted (perhaps die gadget is the leftmost input field on the screen).
The DoBorder function uses die foreground and background numbers to draw and erase the border. Notice that the size of die field is determined from the gadget’s Width and Height fields. The RastPort in which to draw is readily available from the window address field in our STRNODE structure.
To see how to use this system, refer to Listing Four, demo.c. The program opens a new7 screen and window and attaches the seven suing gadgets mentioned in the example above. The user may move between any of die seven input fields using the arrow7 keys and acdvate the current field by pressing the RETURN key, or any field with the mouse. The screen and window definitions are contained in Listing Three, demo.li. Incidentally, these structures were generated with PowerWindows 2.0 from Inovatronics Inc. One other programming aid w7as used in contructing the demo. Also published by Inovatronics, it
is called, strangely enough, Inovatools I. The package consists of a library of extremely useful routines which may be linked into your executable C file. I have used but one function from this package a vert7 handy litde routine called GetlntuiMessage. It simply monitors a windowr’s message port and sends back Turbo Charge Your Amiga!

Anything interesting that comes through. GetlntuiMessage performs no other wizardry; you can accomplish die same thing with the old standby "while-loop.” Wish list The functions presented here bring the Amiga's keyboard input up one more notch on the evolutionary scale. But by no means do they bring it into the class of what is possible, even on garden variety PC’s. If any of you Intuition Higher-Ups are reading this, please consider enhancing keyboard input oh the Amiga.
At a minimum, we should be able to pass an input “picture” into a string gadget to provide a validation a bit more detailed than “is it a string?” or “is it an integer?”. For example, if we expect a date to lie entered, we could send the picture “99 99 99”- The 9's would tell Intuition diat the user is only allowed to enter numbers, and die slashes would become part of the inpuL string, so the user would not have to type diem in. A phone number picture would appear as “(999) 999-9999" and a social security picture would appear as “999-99-9999”.
“Hooks” would also be nice. Hooks are places where you can insert your own functions which are executed at certain preordained times during data input. If Intuition had hooks, programs would not completely lose control while the user was entering data into a string gadget. Hooks are implemented as pointers to functions in C. Each string gadget could have a preinput function, and a postinput function. These pointer locations could easily be placed in the Stringlnfo structure, In your program, you would store the addresses of your pre- and post- input functions, and Intuition would call diem
before and after the data input, respectively.
