The Amiga development community has written over 1100 software programs for the Amiga 2000 and 500, ranging from WordPerfect's Amiga version of its popular word processing package, to programs that take advantage of the Amiga's sound, video, graphics and animation capabilities.
According to Max E. Toy, president and chief operating officer for Commodore Business Machines Inc., 'The Amiga's success is due both to the wide variety of sophisticated software support it has received and to the Amiga's advanced operating system.
The Amiga offers true multi-tasking capabilities which allows users to do several computing tasks simultaneously. For example, while writing a lengthy report, a user can concurrently print the document, open a separate window to create a bar chart and run non-rclated software tasks as an integrated function."
"We see the Amiga becoming a standard business computer as well as the graphics system for corporate communications departments, television studios and video production houses," Toy continued. "Because we designed the Amiga to be completely expandable, an Amiga purchased in 1988 will continue to meet the personal computing needs of users well into the 1990's.” This edited notice documents the Amiga's rise to the class of prominent computers.
The figure is even more impressive when compared to the 200,000 installed base Commodore announced last summer, representing a growth of 200% over the last 10 months.
The only notable omission here is recognition of Amiga users. The advanced software and hardware now available for the Amiga are tied directly to the Amiga users' enthusiasm, support, and continuous demand for better products. Now, as we see the promise of a truly superior multi-tasking environment, I believe Amiga users deserve a lion's share of the credit.
This upbeat news in no way means we should drop our guard. Every facet of this machine has incredible potential waiting to be tapped. From video to sound, from multi-tasking to machine architecture, the Amiga is still as new and exciting as it was nearly three years ago.

P. O. Box 869 Fall River, MA 02 722 Greetings Amazing Computing!
Thank you for including the informative "Macrobatics" feature written by Patrick J. Horgan (AC Volume 3 Number 4). The subsection "Writing Stand Alone Programs with the Aztec Assembler" has freed me from the comparatively slow Amiga Macro Assembler (vl.l). I would like to, however, point out other fundamental differences between the two. Perhaps this will benefit other readers.
In the Aztec reference manual (mine is for the V3.4a Developer System) I have found no reference to the current program counter symbol. The assembler will accept the symbol but will not produce code accordingly. Use labels instead to overcome this difference.
Also, the Amiga Macro Assembler will assemble files where code and data sections are not separated by SECTION directives without causing an error. The Aztec assembler will attempt to assemble DC and DS directives as code if the sections are not separated by the proper SECTION, DSEG, or CSEG directive, thus causing an error for each.
Another difference, and a major advantage over the Macro Assembler, is the fact that the Aztec link libraries also contain C functions (such as printf) which can be used by pushing arguments onto the stack (in reverse order) instead of loading them into registers, Please keep the "technical" features coming. They are much appreciated.
Sincerely, Michael McFarland California AC will continue its tradition of providing well rounded and informative articles for our readers. How "technical" these articles are is directionaly proportional to the amount of good technical articles submitted.
Thank you for your notes.

P. O. Box 248 Westwood, N.J 07675 (2011 666-601 1 2000 is that
the 2000 has more and better expansion ports. Is there a
device available or under development that will give the 1000
those same ports? Is it possible at all? If not, what is the
closest thing to it? If the machines are internally the same,
it seems plausible. I would like to be able to use A2000
hardware on my 1000, specifically a hard drive and the
Why can't Kickstart and Workbench be on the same disk? Kickstart is only 256K, and if you cut away some excess on Workbench, they should fit. That way, you could boot with just one disk. I know WB is a DOS disk, and Kickstart is not, but I don't understand why Commodore designed the system to be booted with two disks when they'll fit on one.
Also, under AmigaDOS 1.3 you may boot from a hard disk; does that mean you can put Workbench and Kickstart on it?
Why do A1000 peripherals cost more than those for the A2000? For example, an A2000 20MB hard disk is as low as S319, but the lowest one I've seen for the 1000 is about S800. 1 realize A2000 drives are internal, but drive cases can't be that much more expensive!
I've seen a lot of ads for "unpopulated" RAM boards, but never an ad for the RAM chips, how much are they, and how easily are they installed?
A thousand thanks for the answer to these questions.
Sincerely, Howard Fincher Florida Whew!
hope AC can answer all of your questions. In sequence: Yes, the Amiga 1000 is no longer in production. However, these machines represent a very large percentage of Amiga users and everything is being done by Amiga software developers to stay compatible with the Amiga 1000.
Expansion devices for the Amiga 1000 are available from A5DG and Byte by Byte. However, these expansions are not designed for Amiga 2000 cards and not all cards will work with them. From the original design and implementation of the Amiga 2000, it is not possible to use cards designed for the special chip access and slot designs of the Amiga 2000 in any expansion device for the Amiga 1000.
Kickstart and Workbench do reside on the same disk if you use AMIGA Business Systems Kickwork 1.3 as reviewed in AC V2.9. There are additional programs available in the public domain.
Amiga 2000 peripherals are not always cheaper. However, the Amiga 2000 has taken advantage of the more popular IBM style peripherals and these are more plentifull and less expensive.
RAM chips are extremely expensive at the moment and very few dealers or developers are confident to publish prices based on the unpredictable pricing now available. Most of these developers will either quote you a price at the time of your order or they will suggest an alternative source.
Good Luck, and keep the questions coming.
Dear AC, Thank you very much for your reminder on my subscription renewal. I did not know that I was due because your system is very confusing. The magazine has a Volume and Number on it and the label on the envelope says 5 88. Thanks again and keep up the good work on the best Amiga mag on the market.
Cordially, Stephen Marhoffer, New Jersey Our system is not really a mystery.
The Volume Number represents the year in production. Thus Volume 3 stands for
1988. The remaining number is the number of the month. Thus V3.6
means June (month 6) of 1988.
However, due to the ITS Postal System requirements for 2nd class subscription mailings, all of our future issues will have the month printed on the cover. This does have one small drawback.
AC publishes the June issue to be sold and to be read in June, now AC will be sitting on the stands with a June date beside other publisher's products with August and July covers.
A Virus Residing in your RAM Dear Amazing Computing: Yes, even us Green Berets here in Southern Germany have time to use our Amigas, so far from home!
Anyway, here is my tip. Thanks for your great magazine!!
Just when you thought it was safe... Virus II. There are several strains of Virus II. There are several strains of virus that will remain resident in your Amiga 500's even after a complete shutdown! This will occur if you own a RAM expansion
i. e. 501 RAM Expansion with a real time clock. The new strain of
virus remains resident in your RAM expansion after any and all
shutdowns, with the assistance of the battery (which happens
to keep your built in clock running). Solution: remove the RAM
expansion, open the casing (which may require some soldering),
remove the battery, the vims will then be removed from the
RAM, replace the battery. It’s best for owners to check newriy
aquired disks with one of the many virus checkers available.
Sincerely, Gill Shatto Germany This is the first we have heard of a 7MM resident virus hiding in a battery supported Ram card. In a recent report from Commodore to its American Developers (see the article concerning the Washington Amiga Developer's conference at the end of this issue), it was claimed that the best ?

Dear Amazing Compuling: I have noted some of the complaints from users regarding the speed of the 64 Emulator by Readysoft.
Now its true that there is a noticeable speed loss, but if you program in Basic, there is a way to speed up those programs. As long as they are pure Basic programs (no ML subroutines), just compile them with the Basic-64 compiler available from Abacus Software. Then, when run on the Amiga via the 64 Emulator; Voila!
The programs run as fast, if not faster, than the standard version on a C-64.
The combination of the Readysoft Emulator and Abacus Compiler makes for a winning combination. Perhaps Abacus will release their compiler on
3. 5 disks for Amiga users who dabble in the world of the C-64.
Try it! 1 guarantee you will be pleasantly surprised!
Yours very truly, David A. Bush Canada It seems you followed the old adage, "If it is broken, program it!"
Dear Amazing Computing: This is the second time I have had the need to write you. First time was for added memory and you published the article "A McgaByte without MegaBucks" by Chris Erving which 1 did and it worked fine.
Since this time I have purchased
A. S.D.G. MiniRack at the AmiExpo in New York with two megs of
RAM after hounding Perry Kivolowitz for this item until he
finally gave in and sold his model at the show.
January of this year I decided to buy a hard drive system so I went out and purchased a C-Ltd 33 meg drive, after a slight problem with SCSI Host Controller and a couple of month's passing by I finally had a complete system, I felt. This was short lived as my A.S.D.G. board would not work plugged into the controller, two female boards, so off to the local Tech School and I had a straight pass through double 86 pin male board for the job.
Home and happy it would not work either.
I phoned Perry Kivolwitz, and he told me to read Amazing Computing's article on PAL help so I read the mod, got the wire as needed and presto, plug the system all together and you're right, all problems cured, memory and hard drive now working properly.
So far, two of my most difficult problems have been answered by your magazine and the articles you publish, keep up the good work and I would like to thank Perry Kivolowitz for the MiniRack and Pal help article page 58, Vol 3 Number 3, and your magazine for the proper drawing to do this which was in a later issue.
Thank you, Tom Price Canada Dear Amazing Computing: You would do your readers a real service if you advertised that you accepted advertisements only from those organizations that did not bill customers credit cards prior to actual shipment of merchandise. Last spring I was burned by an AC advertiser relatively new to Commodore products. It was determined (after credit card billing shock) that merchandise was advertised which was not in stock and would not be in stock until a sufficient number of orders were placed. Over $ 4500 of mine was tied up for four months. The advertiser was found to
be billing customers upon receipt of their telephone orders and using the "no interest loans" until sufficient funds were on hand to place quantity orders with the manufacturer.
Recently, another advertiser with whom 1 traded for several years instituted this despicable practice of charging customers credit cards on receipt of order and without merchandise being in stock to ship. In neither case did the advertiser advise me of their unscrupulous practice when their telephone order was placed.
M. N. Yoder Virginia To the best of my knowledge, it is illegal
to charge for a product on a credit card before it is shipped.
Besides, the credit laws are so secure in most states that the
customer retains the right to refuse payment and thus have any
erroneous charges removed from the account.
Amazing Computing has no way to judge the dependability of advertisers from their advertising alone. AC relies on the feedback from its readers to be certain that everyone is treated fairly. If anyone ever has a problem with an advertiser in AC, we want them to give us a complete description of the incident in writing to: Ad Complaints Amazing Computing PiM Publications Inc.

I read R. Wainwright's letter in issue v3.4. In his letter he asked if someone could come up with a Fat Agnus Hardware hack that would make it possible to install the new Fat Agnus chip and the extra 512k of chip memory has already been solved.
I installed a hack by Chris Erving, about a year ago, that adds 512k of memory to the Amiga system. This little hack had one small problem, under Workbench 1.2 the Amiga autoconfigured the extra memory as chip memory. Since the original Agnus chip did not recognize 1 meg of memory it caused the system to fail to work properly, so a small modification was added so the new memory could be accessed as fat ram. Now that the new Fat Agnus chip recognizes 1 meg of chip ram, I believe Chris Erving's hack, without the modification, should work.
1 hope the solution for the extra chip ram is this simple, if so, half the battle in getting Fat Agnus chips to work in Amiga 1000s would be over.
Sincerely, Jeff Robel Texas 1 hope the publication of this letter will produce some reaction. The effort to make the A1000 Fat Agnus compatible may become a non-issue as the new "fatter Agnus" is released.
Dear Amazing Computing: USING THE ECHO COMMAND Here is a hint to speed up Amiga DOS. When using the ECHO to print more than one line of text, there is no need to use a separate ECHO for each line.
Thanks for the ECHO'S wordwrap feature, you can just combine all your lines of text. This hint will definitely qualify as a "startup-sequence" speeder-upper.
Hope you can use this helpful hint.
Yours truly, Dennis Sprangcr Wisconsin Dear Amazing Computing: Let's talk about file requesters!
There are a great many ways to allow an Amiga user to select a disk file, and the differences between them can add up to a colossal savings (or waste) of the user's time. My pet peeve is the Deluxe Paint style of requester (sorry. Electronic Arts, you created a masterpiece EXCEPT for your file requester!) It makes assumptions about two things: first, that it knows which device your picture is on, and second, that you are too lazy to type in the name. A typical scenario: you select LOAD from the top menu; Drive 0 grinds away incessantly, finally providing you with a menu of the WRONG disk. You
click on DFI:, and 30 seconds later a new list of files complete. You can do nothing until the grinding ends. Now you scroll through the list to find your file, click on it, and click OK. 1 thought the mouse interface was supposed to be convenient.
A slight improvement is the Scrtbble! TxEd style of file requester.
At least it doesn't make you wait for ail disk activity to stop before allowing you to choose a new path. Sometimes I'm actually able to scroll-search for the filename during disk access. More often, the filename vanishes just as I position the mouse arrow to click. On other occasions, 1 choose to type in my filename, fighting the distractions of the drunkenly flashing cursor and the ever-changing file list.
And then there is the Maxiplan requester, not perfect, but the best I have yet found. It actually stops and ASKS YOU IF YOU NEED A DIRECTORY. What a concept! If you want to search your disk for files, you click your mouse pointer in the menu window to begin. You may first select a different device or pathname. You may even (how antiquated an idea!)
Type in your filename yourself instead of scrolling through a list and clicking.
But until you authorize it, there is no disk activity at all - just beautiful silence.
I hope 1 haven't insulted anyone needlessly (I would actually like to see some software developers improve their file requesters, to make the insults worthwhile). And I don't believe the ultimate design is here yet.
Why not a requester that waits for you to intiate a disk search (with a DIR button), and also allows you to select a file at any point during disk activity?
I would also like to see DELETE, RENAME and MAKEDIR part of the file requester standard format, so that proper disk housekeeping can be done, Let's keep in mind that it’s our time and our disk drives at stake, and get the most convenient file access possible.
Sincerely, Dick Bourne Canada Hang in there. Perhaps with a great deal of user feedback, we can get all developers up to speed with the Amiga. However, do be kind, it is not entirely their fault. They probably have never had this much machine with this many opportunities before.

AMAZING REVIEWS V By Steve Garte r Thiie-of-Day Clock Bear Time is another entry in the Amiga 1000 Battery backed clock market. By itself, that news is not particularly noteworthy, since several are available already. But there are several features that set Bear Time apart from the rest of the crowd. As you read, I'm certain you will find at least one good reason to own a Bear Time; I found a couple. Let's take a brief look at some of its features.
Like all the rest of the Amiga 1000 clocks, Bear Time needs a place to live, but unlike the rest, Bear Time doesn't occupy a port. Similar to products that use the 68000 socket, Bear Time uses one of the P1A sockets next to the 68000. You simply remove the PI A, plug it into the Bear Time board, and plug the board into the P1A socket.
Now, Bear Time is ready to run, without interfering with the printer, the mouse port, or any other port.
The software required to run Bear Time is quite flexible. It allows you to include a simple command in your startup-sequence to get the time. Or, if preciseness is your cup of tea, you can use a different version which keeps time accurately (including daylight savings time and leap years).
Perhaps the most attractive feature is its price. The kit is just 517.50. And if you don't want to trouble with the relatively simple assembly, Bear Products charges S10 to assemble and test it. At this price, a good argument could be made for replacing the clock that keeps messing up your ports.
Enough of the hype; I'd like to tell you about putting it together and installing it.
The kit contains eight parts, and is slightly smaller than a 3.5" diskette.
You need a low wattage soldering iron, solder, and a couple of other common tools. Assembly is simply a matter of soldering the parts onto the board. Bear Time comes with illustrated, easy-to-follow assembly instructions. It took me about an hour to assemble mine.
The kit method has a couple of drawbacks. Even if you're a novice at soldering, you really shouldn't have any problems. However, there are a number of solder points to make, and if you don't do a good job, you could be faced with checking out each point for a bad connection. Of course, the other drawback is the time involved.
Anyone experienced in this area will not have a problem, but novices might consider paying an extra ten bucks to have it done for them.
Installation is not an easy job, but even if you have never opened your Amiga before, you should do fine. The instructions are illustrated and easy to follow. Once the machine is opened, remove the metal RF shield and locate the chip to remove from the motherboard, place it in its socket on the Bear Time board, and insert the Bear Time plug in the empty PIA socket.
The only place to get hung up here is in removing the PIA chip. Some of these chips (mine included) can be in the socket really tight. Remove the disk drive in order to get at the chip with a screwdriver. With a little gentle prying I was able to loosen the chip and remove it with an IC puller.
It is important to note that great care must be taken when using the screwdriver method to insert the blade between the chip and socket. This way you will not be touching the motherboard with the screwdriver and running the expensive risk of damaging any traces.
An alternative to removing the disk drive is to remove the plastic back panel. But this requires the use of a long small-blade screwdriver. I was able to use a 4" screwdriver after removing the drive, as the chip is close to the drive.
Once the board is in place and the drive is reinstalled, test your Kickstart screen. Once this is accomplished, the machine is reassembled and you're ready to try out the software.
As I mentioned, the software can be as simple or complex as you wish to make it. If all you want is to know the time, and accuracy is not a priority, than you can use getbt_sm.
You include the command in your startup-sequence and forget about it.
From there on, your Amiga will always know what time it is.
If you are concerned about accuracy, Bear Time gives you a second program, gctbt, that allows you to achieve accuracy to within a few seconds per year. This requires some tweaking of the getbt command line arguments over a period of time. The process involves calculating the inaccuracy of the clock and adjusting for the difference in the command line arguments. You may also include the day and month when daylight savings time begins and ends.
Whichever method you choose, the Bear Time must be set first. This is done using a menu mouse driven program appropriately called SetBT.
You are warned do to this only once.
Jot down the hour, day, month and year when SetBT is run, and these numbers are used in the command line arguments of GetBT.
All in all, I am very pleased with the clock and have been running it for a couple of months now, !t has not interfered with any hardware or software i own, and is advertised to be completely software and hardware compatible.
There is one exception to the hardware compatibility, and it involves products that use an adapter for the 68000. I have Michigan Software's Kwikstart installed, which uses a board that plugs into the 68000's socket and hangs over the PIA chip which the Bear Time uses. This almost eliminates the ability to plug the Bear Time directly into the PIA socket, but I worked up a plug and cable and put the Bear Time out of the way. This fix is not recommended by anybody, but it is working for me. 1 heard a new design is in the works for Bear Time that will eliminate this problem.
Bear Time comes with Assembly, Installation and Software instructions and a disk including the required software. The disk also includes a Hackers Drawer, containing information on the theory of Bear Time accuracy.
Bear Time was formerly known as Time Lord from Amazing Devices, but was recently acquired by Bear Products and released as a kit. The kit is available only through Bear Products.

O n It seems like only yesterday that media pundits were loudly announcing the death of the videogame.
Things did look tense for a while; the demise of ColecoVision and Intelliv- ision were poor harbingers indeed.
Atari's would-be successor to the 2600, the 5200 game system, died a slow and ignominious death amid the roar of bulldozers burying surplus cartridges. The Atari 7800 SuperSystem, which could have been the rage of 1985, instead fell by the wayside during the Warner Communications Tramiel changeover. By the time the 7800 wobbled out of the warehouse two years later, Japan's Nintendo captured the new generation Atari had ignored.
What many in the press did not seem to realize was, videogames were alive and well on personal computers. The C64's and Atari 800's that flooded into homes offered superior graphics and sound, and computing power that the dedicated game systems could not match. It is true the industry has ebbed a bit from the madhouse days of the early 80's, but this was more a stabilization than a recession.
Get ready for the next boom. Games for the Amiga have turned hot, and everyone wants in. Small development corporations are popping up like weeds; entrepreneurs are grabbing programmers and artists, building stables much like the movie moguls of the 30's and 40's did. As I survey the scene, I feel as if I am standing at the foot of an enormous tidal wave that is about to break.
PORTS OF CALL CAN YOU KEEP A SECRET?
Silent Software the company that produced Fire Power and Turbo for Microlllusions is working on what could be some of the most fascinating Amiga projects to date. Among these: a series of stories for the adult sci-fi fantasy magazine Heavy Metal, done completely on the Amiga. Videoscape screen hack wizard Leo Schwab is among those said to be involved in the project; he'll be doing the 3D routines.
Silent Software's founder, Reichart Von Wolfsheild, is in the process of joining resources with an established programming team in what is shaping up to be a veritable programmer's guild.
By Steve Hull Genie: LightRaider People Link: St, Ephen This June's Consumer Electronics Show is a case in point (see sidebar).
Companies like Epyx, which until now offered the Amiga only marginal support, are jumping in full-force.
Companies like Microlllusions which have been strong on the Amiga are doubling their commitment, I hope everyone out there's wearing seatbelts!
GIVE THESE GUYS SOME SANKA In other news, Teknoware, a southern California startup company, will be kicking off their Amiga line this summer with two attention-getters: Freeway Massacre, a "fast driving, hardhitting California freeway simulation in which you play the Freeway Vigilante" and Kill or Be Killed, an arcade-style POW rescue described by its developers as "a disk full of violence." Geeez, fellas, maybe you should lay off the caffeine for a while!
NEWS SHORTS As of mid-April, Cincmaware was just-this-close to signing a deal with the Disney organization. The project?
Cinemaware boss Bob Jacob won't go on the record until the deal's done. I can tell you this: it isn't Roger Rabbit ... Sales of 360 Pacific's Dark Castle have been brisk enough to merit a sequel; look for an Amiga version of Beyond Dark Castle sometime around September or October ... Speaking of sequels, Discovery Software has added 33 new levels to their wall-banging smash, Arkanoid. Registered owners "Jackets are being produced...business cards are being printed...software is being designed." When asked for names, Reichart answered simply, "the best." You could hear the gleam in his eye over
the phone. A Fire Power sequel Return Fire and the Sachs version of 20,000 Leagues Under the Sea are likely first projects.
DARK CASTLE of the original will be able to upgrade, though at this writing the cost has not been decided. Discovery hopes to have Zoom, an arcade space chase, on the shelves by the time you read this ... Microdeal U.K. is working on a videogame adaptation of the movie Fright Night. Little else is known at this time; Microdeal U.S.A. has seen screen shots, but that's about it.
Enough news let's hit the reviews!
CAME OF THE MONTH Tonight, before you nod off to sleep, bow your head and give thanks that you are not a game developer. These poor folks spend months and risk thousands of dollars trying to figure out what will appeal to the game- buying public, and there are no sure formulas for success. Witness what may turn out to be the sleeper of 1988: a business simulation!
Aegis Development's Ports of Call has only been out a few months, but it has already become a bit of a "cult" item; stories of severe addiction began popping up on the networks almost immediately after its release. One unsuspecting individual popped the disk into his Amiga one afternoon and didn't come up for air until the next moming, when he had to make a dash for work! A friend of mine has amassed a fleet of 250 ships and is threatening to upload the scenario to FERRARI FORMULA ONE can brave the storm, or whether you can afford to cruise the long way around it. Unsavory characters will
tempt you with outrageous sums to ferry just "a handy little chest" putting you at risk with customs.
Then there are taxes, fuel, repairs, mortgage on your ships and much more.
Ports of Call allows up to four players to try their luck at the business of global shipping. Each player begins the game as the head of a shipping company, with five million dollars in starting capital. The object of the game is to build your company's status through a combination of business sense, management, and no small measure of seamanship.
It sounds dry, but the game is seductive. A lot of research went into Ports of Call; Martin Ulrich and Rolf-Dieter Klein spent over two years touring ports on every continent, gathering facts on all aspects of international shipping.
From Piraeus to Singapore, to London's Baltic Exchange the New York Stock Exchange of tramp steamers you might say these guys did their homework. The original documentation filled 50 pages, but was trimmed to about 13 for the game's release.
You won't feel shorted; it's all in the game.
Once you acquire a ship, the next step is to charter a cargo. Depending upon where you are ported at the moment, the country's exports might be agricultural products, nonferrous metals or electronics. You also have a choice of destinations needing these commodities. The trick is to match cargoes and destinations to assure the highest profit for the voyage.
Both shipping rates and expenses fluctuate in response to factors as diverse as crop yields and competition; each company's credit rating rises or falls on its owner's decisions. Success may be achieved through widely varying strategies. You may take the high road, investing in modern, well- maintained supcrships, or you can buy a rusty old bucket and run it until it sinks.
Programmer working for a competing company who had to physically destroy the disk so he could get some work done.
Like the real world of tramp shipping, Ports of Call is never predictable. Rats may infest your hold, or an epidemic may result in your ship being quarantined offshore. Dockside pirates will steal your cargo while you're laid up, and white-collar pirates will dip into the till if you don't keep close tabs on the home office. Heavy weather will force you to decide whether your ship Those looking for action should look elsewhere. Ports of Call has a couple of sequences that some might term "arcade," but these are more in the vein of Lunar Lander than Space Invaders. Taking the helm to navigate
your ship through hazardous reefs, for example, requires a steady hand, patience and skill. Docking the vessel will conjure painful memories of parallel parking from old Driver's Ed.
Days. And of course, there's a big difference between sidling up next to a curb in a Volkswagen Rabbit, and easing several thousand tons of cargo ship up to the dock. Each port is different, and some are worse than others 1 am positive that the port at Basrah was designed by a sadist!
The first Telease of Ports of Call includes a little bit of unintended realism as well; it is possible, through savvy speculation and observing fluctuating ship prices, to build a veritable armada without ever setting sail! Word has it the programmers are planning to make a slight adjustment THE THREE STOOGES to the next release to make such speculation unprofitable.
Lush artwork by Dick LaBarre and Jim Sachs makes Ports of Call easily the most beautiful simulation ever attempted on a microcomputer. Aegis took quite a risk in bringing this title to market; in doing so they have not only produced a playable game, but educational software of the finest sort.
Dark Castle, the initial Amiga release from 360 Pacific, was first written for the Macintosh, where it garnered high sales and favorable reviews. The Amiga version builds on the Mac game with color and digitized stereo sound. The game comes on two disks, and though it can be played on one-disk systems, you of disk swapping.
The goal in Dark Castle is to survive fourteen screens of action-packed arcade challenges: you will face dungeons, laboratories, caves and other such inhospitable locations.
Can expect lots Your opponents include marauding bats, hungry rats, burning eyeballs, and the obligatory fire-breathing dragon. At the end of it all, you will have to defeat the Black Knight. If you get the impression this isn't exactly Mr. Roger's Neighborhood, you're right.
You start out with five lives, a sackful of rocks for defense, and elixirs to restore your health. Throughout the game you may find more elixirs, treasures and weapons to aid in your success. There are three skill levels to choose from, and high scores are saved to disk.
The series of screens accessed through the Info gadget are extremely helpful in fact, you probably won't get very far in the game without studying them. Besides offering hints, the TEST DRIVE screens show keystroke combinations for actions which are not mentioned in the game's brief documentation.
Dark Castle's digitized sound is great.
From the surprised squeak of dowmed bats to taunting ravens (the docs call 'em "vultures," but don't you believe it), the sound effects add originality and humor to the game. In my household (a home long ago used to the cacophony of laser blasts, tank rumblings and alien growls emanating from the computer room). Dark Castle brought people from other rooms saying, "what is that?"
Gameplay is extremely rich, combining elements of the arcade classics Galax- ian, Donkey Kong (Sr. And Jr.), Jumpman, jungle Hunt, and others. It would not be overstating to say that Dark Castle combines the best collection of arcade sequences in any Amiga title to date. Unfortunately, there's a catch.
Dark Castle has an Achilles heel its play mechanics are perhaps the clumsiest and most daunting yet encountered. It's not that it lacks options; you have the choice of playing by joystick, or by a combination of keyboard and mouse. However, trying to get the game to respond to the joystick is an exercise in frustration; the smallest task, such as climbing stairs, takes several attempts and much joystick jiggling.
In addition, nearly a dozen different actions are controlled through various combinations of stick position and the fire button. In the heat of battle, you may find yourself asking, "am I supposed to push the button down then push up, or left, or..." Control via keyboard and mouse is significantly more precise, a result of the game's Macintosh heritage. Still, you are expected to keep one hand on the mouse while the other hand manipulates seven keys. Considering all that happens on screen, there isn't a lot of spare time for glancing at the keyboard. If you're a touch-typist, you'll love it.
Veteran gamers especially those who grew up with Apple II's have seen keyboard-oriented arcade games before, and may not consider this a problem. Dark Castle is a very good game, but its play mechanics may make it inaccessible to some. I recommend the game to advanced arcade fans but not to beginners.
Ferrari Formula One is Electronic Arts' latest entry under their Sports Legends series. Like EA's previous Sports Legends title, Earl Weaver Baseball, Ferrari Formula One was written for fanatics. Those people who eat, sleep and breathe Formula One class racing may risk losing all contact with civilization over this title. On the other hand, if you buy Ferrari Formula One expecting an arcade game, you will be disappointed. It is a simulation without question the most complete of its kind ever attempted.
On the surface, Ferrari Formula One appears to have a lot in common with Pole Position. In reality, that is like comparing Sublogic's Flight Simulator II with Gee Bee Air Rally. We're talking a quantum leap in sophistication here.
Ferrari Formula One can be played on many levels. If you simply want to get out on the track and run 'til your tires melt off the rims, you can. You'll be missing the point of the game, but you can. At its most involved, Ferrari Formula One gives you the opportunity to pilot your Fl 86 through an entire season of 16 courses in locations around the world. Success requires more than raw driving skill; a little feel for engineering helps a great deal.
You begin preparing for the season at your test track at Fiorano, Italy.
Fiorano serves a dual purpose; it has the facilities needed to test and perfect the ideal configuration of your car, and also a track on which you may develop your driving skills.
The level of detail to the game is staggering, in the Dyno room, you can test various fuel mixtures, monitor the cooling and electrical systems, and graph the effect of changing engine control ROMs. Yes, real Ferraris use computer chips to optimize the engine for efficiency or raw power. You may change the suspension, gear ratios, or mix and match between six tire compounds. There is a wind tunnel, which you will use to adjust the car's wings for the perfect balance between downforce and drag. Fortunately, designer Rick (Racing Destruction Set) Koenig had enough mercy to include a computerized
crew chief Mauro to offer expert advice.
Ready to race now? Not so fast, A.J. You must make it through a series of five track sessions before you get to play for keeps. There are two practice runs and two qualifying runs in the days leading up to the race, plus a 30- minute warmup on the morning of the real thing.
'Thirty-minute warmup?" I heard someone gasp under his breath. Yes, in Ferrari Formula One, everything short of repairs and international travel is done in real time. A regulation Grand Prix race covers approximately 310 kilometers, or about two hours. That works out to about 120 Earth-minutes on your Amiga! Ferrari Formula One doesn't cut corners, but you can if you want to its Race Control lets you trim down races to as few as 18 kilometers. That's a thoughtful addition for those who can't afford to make this game a career. You may also stretch a season over several sessions by saving
your current standings to the disk.
Overall, does Ferrari Formula One "work”? Sort of. Many people will enjoy getting in and tinkering with the car's specs. However, the action sequences are pretty weak. The race graphics are only so-so, and the sound bears greater resemblance to a Sunbeam blender set to puree than a full- throated Ferrari turbo. Finally, the mouse proves to be a truly miserable control device for a driving simulation.
If you're a true racing fan, interested in the intimate details of life on the Grand Prix, run, do not walk, to your dealer and pick this one up now! On the other hand, if you're looking for real whiz-bang driving action on the Amiga ... I'm afraid such a program has not yet been written.
Accolade's Test Drive is escapist fantasy at its finest the chance to demolish several million dollars' worth of fine sports cars and live to tell the tale!
Actually, demolishing Lamborghinis and Porsches is not the object of the game, just an entertaining fringe benefit. Test Drive offers the unlikely scenario of a car dealer allowing you to check out the pick of his lot, including such heady machines as the Lotus Turbo Esprit, Ferrari Testarossa, and for buy-Amcrican purists, the Chevy Corvette. A responsible citizen, you promptly grab the keys and beeline it for a leisurely 120 mph run to the top of a mountain known only as The Rock. Now we know why daddy took the T-Bird away.
The game begins with automobile selection. Each of the five cars may be viewed, along with a collection of stats as complete as anything you're likely to find this side of Car & Driver. Such esoterics as engine torque and compression ratio are displayed, along with performance characteristics such as braking distance and acceleration.
Once you've chosen your beast, you're ready to begin.
Play takes place from a driver's eye view behind the wheel; the object of the game is to push your machine as hard and as fast as you dare, while avoiding collisions with other traffic or The Rock.
No muscle car would be complete without the appropriate protective device. Seatbelts? No a radar detector! This one's pretty good, too, and it sees around comers better than most real ones do. It tweets when you're being clocked, and displays a series of red LED's; when all are lit, Smokey's takin' your picture.
At the first tweet of the radar detector, you may either slow down (Wimp!) Or hit the gas and get out of there with all haste. Sometimes the cop doesn't appear, but other times he'll be in your rear-view mirror with his bubblegum machine flashing bright as you please. You may then meekly pull over (Wimp!) And accept your ticket, or try to outrun him. Contrary to what you may have read in other reviews (Wimps!), it can be done though if the police car gets in front of you, cut your losses and park. There's no way to get by it, and rear-ending the cruiser earns an automatic GAME OVER.
The game's graphics are a mixed bag; the cars are detailed both inside and out, though the view outside the windshield is simpler. The engine sounds are more convincing than those of Ferrari Formula One, but that's not really saying a lot. The sounds are identical for each car and anyone who thinks a Porsche and a Corvette sound alike needs to get his ears dy no-tuned.
Gameplay is pretty simple you're basically maneuvering a never-ending right-hand curve. You have control over acceleration, brakes, and shifting.
Each car has a functioning speedometer and tachometer; you will learn to observe the latter after blowing a few engines!
The way Test Drive handles mishaps is pretty lame; whether you blow the engine, sail off the side of the mountain or collide head-on with a truck, the windshield shatters and the sound trails off. Ehhh. On the other hand, the programmers worked in a few nice touches, like bugs splatting on the windshield and the staccato thuddathuddathudda when your tires cross the raised highway markers.
One of the better effects occurs when your car tops a rise in the road; it'll make your stomach lurch!

The documentation to Cinemawarc's The Three Stooges begins with a quote from Leonard Maltin that I would like to lift shamelessly: Maltin points out that people can be divided into two groups, "one composed of persons who laugh at the Three Stooges and one made up of those who wonder why." It's hard to improve on a thought like that.
Cinemaware's newest title, produced under license by Columbia Pictures, is aimed squarely at the first group though like a thrown pie, it may hit the second group also! Three Stooges is a crazy, light-hearted romp that will appeal to Stoogeophiles (their word, not mine) and the uninitiated alike.
As the game opens, the Evil Banker (pat. Pend.) Appears at the door to Ma's Orphanage, threatening to (what else?) Foreclose. Ma is distraught. The pitiful orphans are distraught. The Stooges appear on the scene and promise to save the day. Now Ma and the orphans are really distraught.
Three Stooges is, at heart, an expertly- designed computer translation of a board game. In it, Larry, Moe and Curly attempt to earn, win or otherwise find the money to save the orphanage. To determine the direction the game takes, the Stooges crowd around a map, while above them an enlarged view shows Moe's hand randomly jumping between alternatives such as HELP WANTED WAITERS, BOXING, or TRIVIA. You select by pressing the fire button at the precise moment that hand lands on the square (if you take too long, the game chooses for you). Stopping the finger where you want it is easy at
first, but the farther you get into the game the faster the hand moves. There are also mousetraps on the map, and if they snap on Moe's fingers too many times, the game's over.
Moe's finger can be slowed by knocking some sense into Larry and Curly; the joystick comes into full play as you fake, duck and slap Moe's cohorts. The hand slows a bit each time you connect but if you miss, speed increases. The slapstick action, plus Moe's digitized voice rasping, "YOU IDIOT," make this portion of the game as much fun to watch as it is to play.
The Three Stooges' arcade sequences are the most playable seen in a Cinemaware title yet. All are based on sequences from Stooges' films, and in many cases actual digitized sounds and graphics from the movies are integrated into the action.
There is the inevitable pie fight in the Hoiti Toiti Club, where the Stooges obligingly serve pies to three high- society types who demand, "LET ME HAVE IT!" Points are awarded for pies "delivered" (ahem), but the hoiti- toitis shoot back, and five bullseyes end the scene. There is a hilarious hospital scene taken from the Stooges' best Columbia short subject, Men In Black, where the three race after a demented nurse, swiping dropped medical supplies and leaving mayhem in their wake. There's more a hilarious scene from Dutiful But Dumb where Curly attempts to steal crackers from hungry oysters
in a bowl of soup, and a challenging urban obstacle course for Larry... but don't let me spoil it! Beside arcade challenges, you may earn points by successfully answering multiple choice questions on Stooges' trivia.
The sound, music, and graphics are extremely well done. In addition to the artists and programmers responsible, it is no accident that Cinemaware audio and video compression specialists are also credited right up there with the producers in the opening credits.
There are few things I don't like about this game. The pause feature is weak; like King of Chicago, you pause when the game lets you, not when you want to. Cinemaware recommends two drives; though the game will run on one drive, the frequent disk swaps kill the mood. Even with two drives, disk access slows the game's pacing, though Three Stooges may be installed in expanded RAM or on a hard drive (using the key disk method to start) if your system is so equipped.
Let's face it, these are quibbles.
Cinemaware has pulled off quite a feat with this one a truly funny computer game. As with the Three Stooges themselves, there are going to be those who love this game and others who wonder why. But that first group's gonna be big.

• AC- Microlllusions is going to turn some heads at June's
Consumer Electronics show with the announcement of an
exclusive and unprecedented agreement with the cartoon giant,
Hanna-Barbera, to produce videogames based on the characters
Scooby Doo, Johnny Quest, the Rinstones, and the Jetsons. Look
for at least two titles, and perhaps all four, by year’s end,
Microlllusions' dungeon adventure, Land of Legends, should be
hitting the streets as you read this, with the followup title,
Dungeon Construction Set, expected by July. DCS allows you to
create dungeons with many levels and mazes and design horrific
critters to wander 'em!
At CES, Accolade will announce ports of three games to the Amiga.
Pinball Wizard fulfills the promise Electronic Arts made three years ago to produce Pinball Construction Set; Accolade's version features five ready-to-piay games plus a game builder. Mini-Putt takes Mean 18's user interface to the miniature golf course; no sand traps, but then, Mean 18 didn't make you deal with windmills either. In 4th and Inches, Accolade brings to the gridiron the kind of realism it introduced in Hardball; players may challenge each other, or go head-to-hcad against the computer. A 4th and Inches Team Construction Set planned for August release will let you build any team
player-by- player, right down to the names, jerseys, positions and individual characteristics. Think of the fun you'll have pitting your high school's cross-town rivals against the Dallas Cowboys! Accolade plans to include its own office staff 'The Accolads" ¦on the disk.
Epyx's CES announcements arc expected to show that the company is serious about making up lost time on the Amiga only fitting, as Epyx Chairman and CEO David Morse was the founder of Amiga Computer! Those were the old days, when Jack TramieTs secret plan for capturing the market revolved around the Commodore 16...but enough reminiscing... Final Assault is a mountain climbing simulation, with realism assured by technical consultant Eric Escoffier, a world-class climber. Aspiring Sir Edmund Hillarys will have the choice of climbing rock cliffs or glacial ice; success hinges on skill, but also
on how well you prepare for the climb. You must pack a rucksack, choosing from 50 items ranging from pitons to provisions.
Fortunately, a training slope is included.
Epyx has licensed the search-and- destroy contest Battleship from Milton-Bradtey, with plans for third quarter release. Street Sports Football stars the kids in the neighborhood facing each other on a field of battle that includes puddles, oil slicks, and cracked sidewalks. Street Sports Basketball is also expected to be released within six weeks. Tower Toppler is an intriguing game of skill that takes place on a rotating 3D tower. The object of the game is to make it past obstacles like crumbling ledges and hostile creatures, then destroy the evil machine at the summit. Techno Cop enlists
players as members of an elite police force. Your equipment includes a computer wrist- watch, high-tech automobile and the ever- useful criminal radar locater. Your mission; Nab the vermin! Chief vermin: The international crime family, D.O.A. Sounds socially redeeming... The Game: Summer Edition (not to be confused with Epyx' successful Summer Games) is a series of Olympic contests set in Seoul, South Korea. The game's designers have tapped experts from the United States Olympic Committee, and are currently studying miles of videotaped of Olympic events. Among those tentatively planned: the
highspeed bicycle velodrome, archery, springboard diving, and miscellaneous track-and-field competitions.
This ambitious effort is also slated to include such gymnastic events as the uneven parallel bars and rings, though the latter is proving to be a real trick to program. The Game: Winter Edition, is also in the works.
Coming in under Epyx' U.S. Gold line, Sports-a-Roni, a game featuring a series of nonsensical games of skill set in various locations throughout Italy. Among those mentioned: Pasta-plate balancing in Pisa, and a gondola-bound pillow fight on the canals of Venice!

P. O. Box 201 Los Altos, CA 94023 Space Age Gladiators What do
you get when you merge the gladiator sports of ancient Rome
with the zenith of space-age technology?
Why, Ebonstar, of course. This latest entry in the arcade-style space battle sweepstakes comes from Microillusions. Don't be fooled by the familiar premise, though this isn't your run of the mil! Space game.
The Ebonstar corner of the galaxy is the year 3000's answer to the Coliseum. Here, gladiators, cased in fleet space crafts instead of armor, try to knock each other into a pre-fabricated black hole. Each ship is equipped with a bottomless cup of energy bolts to bump opponents closer and closer to the yawning abyss.
You didn't think it would all be that easy did you? Besides worrying about your own hide and vaporizing your opponents, you'll also have to contend with a bunch of nuisances. The Arch, the rough-edged computerized referee, releases ships from time to time to keep you from even thinking about trying to destroy the black hole. (You can temporarily zap it with a well- placed shot.) And these babies aren't called Rival, Inflictor, and Assassin, and Nemesis for nothing. Nemesis, the nastiest of the bunch, chases the player closest to it, hurls fireballs, and gets faster every time you temporarily
deposit it into the pit. Arch does have a heart, though a small one, but a heart nonetheless. It occasionally tosses objects that increase your firepower if you can track them down.
Ebonstar can be played by up to four playersat once, and two-on-two matchups really test your ability to work as part of a team, joystick, mouse and keyboard play are all supported and a handy Keyboard Reference Card is included. If you think you could have gutted it out as a Roman gladiator, test your mettle in this space-age fight for life.

(800) 522-2041 Cure Compatibility Blues When Commodore decided to
be a bit more "IBM-ish" in the designs of the ports on the
A500 and 2000, hardware compatibility became an immediate
issue. The change made to the parallel port was especially
significant, since so much hardware was already on the
market for the A1000, with its old- style parallel connect.
So, what's a hardware user to do when he upgrades to a 500 or 2000?
Get in touch with Amicore International, makers of Transvestor 1000, Transvestor 2500, and Transvestor 2500 Plus. Transvestor 1000 attaches to the A1000 and allows the 1000 owner to use products designed for the 500- and 2000-style parallel port.
Transvestor 2500 returns the favor for 500 and 2000 owners. With this connector, most products designed for the 1000 parallel port can be used by the 500 2000 owner.
The Transvestor 2500 Plus picks up where the Transvestor 2500 left off. A few A1000 products Digi-View, among others cannot be used on the 500 and 2000, even with Transvestor 2500, because of voltage problems.
Transvestor 2500 Plus includes its own external power supply to bypass voltage glitches and make all A1000 hardware products compatible.
Hardware compatibility is another problem you can now lay to rest.

by David N. Blank BLANK@BRANDEIS.bitnet DNB@BRANDEIS.csnet
With the release of the latest upgrade to the relational
database manager Acquisition 1.3F, Haitex Resources, in
conjunction with Taurus Impex Limited, has brought the Amiga
community the most powerful Amiga- specific database program
However, close scrutiny reveals some fatal flaws that cast a dark shadow on the brilliance of this news. This article provides an in-depth look at this relational database manager.
Common Ground Before 1 discuss Acquisition, I would like to take a moment for a quick primer in relational database-speak. If you are already database-literate, please allow mo the chance to match terminology with you. Now, onward to the land of jargon!
For this primer, I am afraid I will have to drag the standard classic example out of the closet and blow the dust off it. A database may be viewed as the computer equivalent of an index card file. Let's ignore the cries of "cliche" and consider an index card file containing the employee information for the salespeople of the Acme Llama Corporation. If we were to pull a card from the file for inspection, we would be looking at the paper equivalent of one database record. Printed on this card is an employee's name, position, department, phone number, and commission percentage. The
information listed after each one of those headings on the card are fields. Filling out a card (i.e., a database record) for a new employee would consist of filling in a set of blank fields. Using a data entry form, a database can be displayed and edited on a computer screen. A form can be described as a window into a database through which one record is visible at a time. The database form can also act as mask, allowing the user to edit or view the contents of certain fields while keeping others hidden.
Settings The contents of the database may be printed to paper, using a report. A report specifies how the data will look when it reaches paper. In addition, a report can also show the result of operations on the data, such as a calculation of the total of all values in a salary field of a database. The power inherent in a database is its ability to perform complex sorts, searches, and reports on data, a process that would take an incredible amount of time and effort if performed manually on index card file systems.
Now for the funky part of database management: relational databases. A relational database management program allows the user to keep multiple databases of related material and connect them in various ways. To illustrate its uses, let us return to Acme Llama Corporation. In addition to the employee index card file, the corporation also keeps a separate index card file containing personal information on all its employees. This file contains the name, home address, phone number, and hire date for each employee. There is an obvious connection between these two files: namely, one card record in
one file corresponds exactly to one card record in the other
(i. e. the employee card for Mr.
H. H. Munro refers to the same person as the personal card for
The type of information in the two files is very different, but there is still a connection between the two sets of data. We could specify the "Employee Name" field as the link between the two, but this could cause problems if there were two employees with the same name on the staff. Frequently, to overcome this difficulty, a new field containing unique values to tie records together is added to both databases (e.g. an "employee number" field could be added). This is commonly referred to as a key field, and may be used for ordering the data as well.
(continued) Following in the same mindset, a third index card file could be created, containing the set of records detailing each sale made by the company. In addition, each card could list the number of the employee responsible for that sale. At the end of the month, the database manager program, which takes the place of the index card files, could print out a paycheck for each salesperson based on sales commissions of products sold that month. It would first select a record from the employee database. From this record, it would extract the employee number and commission percentage infor
mation from their respective fields. It "would then proceed to search through the employee number field of the sales database for sales made by that person, calculating commissions as it went along. Finally, the database manager would extract the address of the employee from the personal database and print a paycheck for that employee.
This process would then be repeated for each person on the staff. A final report, summarizing all the checks printed that month, could be printed for the president.
Create and Edit Paths A quick aside: all the processing described might seem a great hassle when all of the salesperson information could be kept in a single large database. This leads to the question of the necessity of relational databases.
Relational databases are used primarily for one reason: it is easier and more efficient to work with smaller sets of data than it is to manipulate large ones.
One example can be found using our sample data sets. The president of the company may wish to see a list of salespeople sorted by department.
With the relational database, one is able to sort the employee file without touching the data in either the personal file or the huge sales database.
A sort on one small database is more efficient than one performed on a large conglomerate data set.
Go Now that we speak the same language, a detailed review of Acquisition
1. 3F can follow. The package contains three disks: MAKE (to
create databases), FILE (to perform the actual management
and reporting), and EXTRA (containing sample applications).
A thick, spiral-bound manual accompanies the disks. The user
must supply a disk to hold data. For a good look at this
package, let's follow the example of the five blind men who
attempted to describe an elephant, and take an excursion
through the individual modules of the program.
In the Beginning The Creating module is used to manipulate database skeletons. The user is presented with an empty field definition table. First, each field is given a name. The field name must be fewer than 15 characters long, all in capital letters. This encourages the use of capital letters for all interaction with the program, a throwback to singlecase computers that I find distasteful.
A column for "stream" follows. A stream is a set of Acquisition command language (ACOM) commands executed when an individual field is accessed. (Streams will be described at greater length in the command language section.) The next part of the field definition calls for a specification of field type. Acquisition 1.3F has six distinct data types that describe the data to be stored in each field: numeric, alphanumeric, date, time, clipboard, and special. All but the last two are self-explanatory.
"Clipboard" fields contain the name of an IFF picture file that is attached to that field. This picture can then be loaded from or stored to disk and displayed at will. "Special" fields in this release have IFF digitized sound files attached to them. At first, 1 questioned the necessity of these two file types in a database package, but now 1 can envision several specialized applications that would make good use of them. The ability to store pictures with a record, in conjunction with an image digitizer, might come in handy.
An inventory database could include a picture of each item along with the standard information.
I had greater difficulty searching for an application that uses digitized sounds. The game show application that comes on the EXTRA disk did not seem to warrant the necessary programming effort. This capability may be useful to a linguist who catalogues difficult vocal sounds, or to a speech therapist, but that is as far as my imagination will stretch.
The next heading in the field definition table is storage type. The two storage types are "field" and "memory." "Field" indicates that actual data is kept in this field and is stored on disk in the usual manner. The "memory" type, however, is one that 1 have not encountered in any other database package. A field designated "memory" contains data only for the time the database is active. The data is kept exclusively in memory; it is never stored to disk. It acts as a program variable constant. The manual gives a bank interest rate as an example since it needs to be entered only once per

This is not the usual limit that governs the size of the data stored in the field; it is the character length of the on-screen prompt for the field.
Acquisition has the interesting property of dynamic-sized fields that grow as needed. 1 hesitate to call this a feature, because although it may reduce disk storage space, I expect it to slow down certain database operations. From a programmer's point of view, data structures with fixed lengths are, on the whole, much simpler and faster to work with. Most of the time it is much quicker to move to the nth position in a file or string than have to search for the character indicating the end of a field.
Finally, the user must designate one of the fields in the database as the system index, or key field. This field will determine the sort order of the records stored in the database. The information entered into this field should be unique to that database.
Once all this information is given, the database definition can be saved to disk. Acquisition 1.3F saves its data entry screens in IFF file format. The manual encourages you to edit them in your favorite graphics program (such as Deluxe Paint). Though the manual never mentions it, I had the best success editing the screens using medium resolution mode in Dpaint II.
I find this capability virtually useless.
It is possible to make data entry screens works of art (one of the sample applications on the EXTRA disk for checkbook management enters data into a picture of a check), but I have a hard time believing professional database users would appreciate the gimmick. In all my years of database management, not one client or employer has approached me, sighed, and said "If only my checkbook application could look like a checkbook." Perhaps the casual home user might find this capability amusing, but Acquisition's hefty price tag probably discourages those customers.
Before we leave Creating, note that this module is also used to delete or add new fields from the field definitions of pre-existing databases at any time. This very useful capability, found in all the professional databases, allows the user to expand or contract his database as the situation demands.
Acquisition lacks the ability of other database managers to change a preexisting field from one type to another.
Bridge Over Troubled Waters The next module that comes into play with Acquisition is Bridging. This module specifies the relational links between databases. It may also be used to specify the Acquisition version of a database index.
Acquisition operates using a path analogy. To access data in a database, you follow along a "path" leading to the index file upon which the data is to be sorted. Recall that in Creating, we were forced to designate one field as the system index. The data in this field was restricted to unique values only. It is through this field that Acquisition creates its first path, called the master system path, to the database. The user may create other paths into the database using the Bridging module to access data sorted on a different field than the system index field. The other non-master paths
may be assigned to fields whose contents will not be unique.
One way to better understand this system is to create a more elaborate (and more bizarre) analogy: envision yourself as the cleanup person for the movie 'The Blob," armed with a vacuum cleaner. The direction (read "index field") from which you probe the blob (read "database") with your vacuum cleaner (read "path") determines the order in which each part of the blob (read "data") is accessed. A path acts as an index file for a database. It seems that analogy for the simple concept of an index on a database is an convoluted hassle, until you learn to lump it.
The second use for a path is a bit more natural. Acquisition uses "relational paths" to specify connections between two databases. In this context, one of the related databases is designated the "parent" database, the other is called a "child." A relational path is followed from the index field of the parent to the same field of the child database. Acquisition allows the records of the child to be accessed several different ways.
Acquisition makes creating paths easy.
A simple screen is presented, allowing the user to fill in the database name and index field for system paths, or parent, child, child access order, and index field for relational paths. Paths may also be edited to a certain extent using this module.
Watercolors The last step in the genesis of a new database system is the Pasting module.
This module is used to control the final appearance of the data entry screens and their interaction with the user. The user may re-size the length of the screen prompts listed under "field length" in the Creating module.
Each field may be designated as display only for data entry. In addition, each field can have a stream executed or a phrase spoken by the Amiga's built-in speech synthesizer each time it is accessed. This module also allows for creating Acquisition macros. Streams and macros are discussed in a later section.
Sections of the screen can be moved or copied to re-shuffie the order of the prompts on the screen, as defined in Creating. A curious feature (and I use the term "feature" hesitantly) of Acquisition is that when the return key is pressed, the default movement of the cursor from one field to the next, follows the order listed in Creating's field definition table. This means it is possible to have the cursor jump around the screen, instead of moving to the nearest field in a logical manner during data entry. This effect could be rather disconcerting to the person entering data. There is a
special menu entry to re-order the prompt sequence, but I find the whole idea distasteful. 1 don't believe the user should have to worry about the order of fields in his database definitions; the screen handling routines should be more intelligent.
Pasting also allows the user to draw lines, boxes, and ovals in different styles on the data entry screen. Since this function is probably best handled by an IFF graphics editor, 1 consider its inclusion redundant. Several styles of text may also be placed on the screen. Acquisition has no support for different fonts, but the graphics editor can be used to beautify the data entry screen and make up for this defect.
Push Push Now that the database has been created, bridged, and beautified, actual database management can begin. This is performed by the Filing module.
Filing handles all the on-screen data entry and retrieval functions.
Data entry in Acquisition, especially for multiple databases, is a cumbersome combination of keystrokes and mouse movements that I did not feel comfortable with even after extended use. Speedy data entry is bound to be handicapped by the effort required.
Most of my qualms with the data entry screen handling routines have already been aired, but I would like to add to that list poor cursor key handling. If the screen is in a multi- column format, all of the fields in the current column must be passed through before the editing cursor returns to the top of the next column.
An important part of any database manager is its search capabilities.
Acquisition 1.3F does provide a decent search facility that allows the use of boolean searches (using search criteria that is connected by AND's and OR's).
An example of a boolean search would be "(salary 10000) AND (state "RTT to find all the records for employees outside Rhode Island who make more than 510,000 a year. All search criteria is case-sensitive, which can sometimes be a hassle. Acquisition 1.3F also allows the user to apply this search criteria to its get next last, save, and kill record functions. It will not allow the function to complete if the data does not match the criteria.
This is definitely a useful feature I have never seen in other programs before.
There are several other miscellaneous functions present in the Filing module.
These include control of stream execution, automatic display of IFF pictures, and the ability to save child database records when the parent record is saved.
Acquisition 1.3F also performs record caching; it stores a group of records in memory before saving them in one batch. This speeds up the operation of the database, since the user is not forced to wait for disk I O to finish before entering another record. An option controls the number of records to be cached and the amount of memory to devote to this task.
Let It Flow Once the data is entered into the database, the Reporting module allows the user to display the information on screen or paper. Acquisition allows the user to manipulate and organize the data in several ways. The reports generated can contain the results of formulas based on the fields of the database. Summary information can also be produced.
Acquisition 1.3F has a very interesting way of building report specifications.
A text file is created either in the minimal built-in text editor, or in the user's favorite text editor, as the manual recommends. Ordinarily, I would consider it a hassle to invoke another program to do the editing, but the Amiga's multi-tasking makes it virtually painless, since both Acquisition and the editor can run simultaneously. The report specification text file contains a description of the text of the title, header, footer, and page placement of the fields or formula results to be printed. It is usually a good idea to have a list of all the fields in a database since their
exact names will be needed for the report specification.
Reporting also allows the user to enter criteria to select a group of records from the database to be printed.
Acquisition provides the option of sorting the data in a number of ways.
Designing reports in Acquisition 1.3F becomes more difficult for relational databases. In this case, the paths connecting multiple databases are important. When printing a report.
Reporting performs what the manual calls a trace. A trace is simply the paths that the report program follows through databases as it prints the report. The manner in which a trace operates is called a depth-first search.
This means that the trace will consider a record from the parent database, then all the records in its first child, then all the records in its second child, and so on. The second record of the parent database will not be considered until all the pertinent records of the child databases have been considered.
Reports can be made very sophisticated by the inclusion of ACOM commands (discussed later).
Inside Moves The last official module is Settings.
This allows the user to perform miscellaneous utilities and to configure the Acquisition 1.3F system. The external data import export function is located here. Unfortunately, Acquisition has no direct support for the import or export of records in stored in other database programs' file formats. The user is forced to use the "export to ASCII file" feature of the other database to create a file that Acquisition can read. Settings also allows you to report on or delete various Acquisition objects such as reports, paths, and databases.
(continued) Generally, when records are deleted from a database, they are flagged by the database program as deleted, but the actual data is not purged from the file to save time. As a result, most databases have a separate function to perform the actual purging and reclamation of wasted disk space. In Settings, the user can tell Acquisition to perform the housekeeping functions (as they are called in Acquisition) automatically, on a daily or weekly basis. The user can even choose the day of the week preferred for this task. I consider this level of automation a definite plus.
Extensions There remains only one more facet of the Acquisition program to be discussed: the ACOM command language. The command language with a database manager for automation. In most cases, a program written in a command language can manipulate the database manager as if there were a phantom user sitting at the keyboard.
The ACOM language is made up of three types of commands. The first type consists of the basic constructs: assignment, arithmetic, looping, and input output, commands found in any language. The second type of command is database specific; this includes commands to extract information from fields, convert fields from one type to another, and manipulate databases and records. The third type consists of Amiga-specific commands. These include commands to pop up autore- qucstors and display IFF graphics files.
There are three basic uses for ACOM.
The first is for the mysterious streams I have mentioned before. A stream is simply a set of ACOM commands (255 characters in length or less) executed whenever a field is accessed. There are menu options in Filing that determine the exact events that trigger stream execution.
One use for streams is input verification and normalization. An example of this would be a phone number field in which the application designer wanted to make sure the user entered a value of proper length. If the user neglected to include an area code, the value of that field could be altered so a default area code is tacked on to the front of the entry.
The second use for ACOM is for macros. This term is used for a set of ACOM commands that are executed by clicking on a macro icon. Macros are useful for infrequently performed operations. A good example is a routine that sums up the values of a field in a database and displays the results on command.
The third use for ACOM is full-blown application programming. For most serious applications, program code is usually written to guide the user through the different aspects of the application and to perform automatic database record manipulation.
Footsteps in the Dark To begin my final assessment of Acquisition 1.3F, I must discuss the manual. With a program of this size, complexity, and cost, it is crucial to have good, organized documentation.
The thick manual that accompanies the program is severely lacking in organization and examples. There is one very brief walkthrough of the program at the beginning of the manual, but the rest is devoted to reference.
Even the walkthrough did not always take time to explain the rationale for certain actions, or to define a term clearly. A good example of this is its instruction to "click on the NUMERIC icon" without indicating exactly which icon was the "NUMERIC" one. A few moments' study of the screen in front of me solved the problem, but it never should have occurred. Previous knowledge of a program should never be assumed in a beginning tutorial.
The biggest chuckle in the manual is at the end of the walkthrough: "If this tutorial has not answered alt of your questions, please refer to the appropriate section in the reference text for a more complete explanation." My burning philosophical questions aside, I found the tutorial answered only a pitiful few of my Acquisition questions. Instead, it sparked off an avalanche of new questions that forced me to wade through the manual time and time again. The programs on the EXTRA disk provided the only set of really helpful examples to be found in the package.
Ordinarily, bad documentation would cause me to declare a program unfit for use, but there are points in Acquisition's favor that made me reconsider. First off, I believe that Acquisition is the most powerful Amiga database on the market. The emphasis is on the word "Amiga" since it is obvious this is a pure-bred Amiga product, and has not been freshly ported from another computer.
It is obvious that the developers took great pains to customize Acquisition to the machine. In some cases, this works well. The storage of IFF graphic and sound files appears to me a useful extension of current microcomputer technology. However, there were times when I questioned the appropriateness of an icon-based interface to database operation. Some features, such as the ability to use a IFF graphics editor to customize the data entry screen, were superfluous to the point of distraction.

Intergalactic Development Incorporated Rainbird and Rainbird Logo an* registered trademarks ot British Telecommunications PLC My final evaluation of this product? 1 tried very hard to like it, but there were two stumbling blocks along the way that made it difficult. Despite my familiarity with both icon-based user interfaces and database environments, Acquisition's merger of the two seemed to require unnecessary effort to operate, even after extended use.
The documentation only helped to change my mood ring to the color of frustration. At times, I felt I had just been handed an atomic bomb without instructions on how to bang the plutonium spheres together. There is great power in the system, but without guidance, it is useless.
The program is also not bug-free.
Despite my great faith in the healing powers of meditation, the two visits I received from the guru during normal database operation did nothing for my peace of mind.
I would (hesitantly) recommend the purchase of this rather costly database only to people who:
1) Have had previous database experience (application programming
experience a definite plus). The manual will not teach you
anything about database management besides its occasional
direct connection to stress in the human body.
2) Have a specific application (and implementation) in mind. The
documentation makes absolutely no attempt to help the user
decide how to implement an application or overcome a design
problem. As a result, it seems best to have the details
already worked out. This also prepares the user to spend more
time on translation and less on frustration.
3) Have a definite need for the program's inherent power.
Necessity is the only good reason I can see for the struggle
the steep learning curve entails. If you need to catalog IFF
pictures or sounds, then this may be the database for you.
As I mentioned before, this is the most powerful Amiga-specific database 1 have ever used. However, directly proportional to the power is an extremely steep learning curve that makes using this product a struggle at times. The manual for the package is a source of frustration, running exactly counter to my notion of the purpose of program documentation. The program could no doubt fulfill the needs of brave souls who need the program's power now, but unless they are prepared to dance the masochism tango (apologies to Tom Lehrer), 1 would recommend waiting for the next upgrade or turning to

AMIQ* II I I||i|l*f|« liMiBtrt at Cm nils it -Km ji leg A M A Z IMG REVIEWS BUTCHER 2.0 by Gerald Hull A Fascinating Collection of Image Processing Utilities First Encounters Nearly a year ago I purchased Butcher.
I bought it on impulse, something I rarely do. However, it concerned graphics, in which I have an abiding interest, and was quite inexpensive.
The first thing that struck me was the elegant simplicity of the packaging. Inside some shrinkwrap was a 32+ page booklet made out of 8 1 2 x II paper folded down the middle and stapled. A plastic disk envelope, taped to a booklet-sized piece of cardboard, held the disk to keep it from sliding out.
That was it. A most attractive display of minimalism.
(Version 2.0 comes in a much more "professional-looking" package.) However, if that was the extent of Eagle Tree's ingenuity, I probably would not be writing this review.
Fortunately for all of us, the same cleverness characterizes the software as well. I find Butcher an extraordinarily useful and well-designed program a fascinating collection of utilities that provide an indispensable adjunct to my other imaging software. It's the Swiss Army knife of Amiga graphics.
The Principle of Compllmenarlty Butcher is not intended for creating images, but for manipulating, enhancing, and "abusing" images derived from other sources, such as drawing programs like DeluxePaint, or frame- grabbers like Digi-View. As the manual puts it, "Butcher is designed to complement programs that support the IFF standard."
I first used Butcher to convert images from one resolution to another. 1 had hi-res interlaced images from Digi- View that 1 wanted to convert to lores non-lace, and lo-res non-lace images that I wanted to make hi-res non-lace for letterhead I was designing. (I followed the Butcher manual in using "low" and "high" to discriminate between 320 and 640 pixel widths, and "interlaced" to distinguish 400 from 200 pixel height images.)
Most Amiga programs dealing with graphics require you to specify the resolution right from the start, and (continued) they don't always allow you to change it on the fly. Butcher, on the contrary, automatically changes resolution to accommodate the image being loaded, taking advantage of the IFF standard's "data-gram" component.
Butcher made my resolution transformations easily and quickly. Given my needs at the time, that was enough to warrant purchasing the program, and for some time, that's about all I used it for.
However, I started work on an Amiga project involving a special kind of image processing. Much to my delight, I discovered that Butcher contained a repertoire of features which could do the pixel-by-pixel operations required by my project.
Eagle Tree's release of the 2.0 Butcher upgrade has given me an excellent opportunity to explore all its other dimensions. As you will see, I have discovered many more cleverly designed, useful tools folded away in the program's menus.
Riding the Blt-PIanes Before getting into details of the program, let me describe some of the special characteristics of Amiga graphics. Most comparable micros "hardwire" a particular memory area to serve as the screen display. This simplifies hardware, but imposes limitations on graphics capabilities.
Some computers, for instance, can reach their higher resolutions only by severely reducing the number of displayable colors. Their highest res may only be monochrome. The Amiga, by contrast, is wonderfully flexible in its treatment of screen memory.
The first 512K of system memory in the Amiga is called "CHIP' memory.
It is the area accessible by the special Amiga chips responsible for graphics (and much more). Any continuous segment of memory in this region can function as a "bitplane."
The bits in a bitplane correspond one- to-one with the elementary picture elements ("pixels") which make up the screen display. Different-sized bitplanes result in different-sized screens. For example, 8000 bytes are enough for lo-res non-lace; for hi-res interlace, 32000 bytes are needed.
By stacking up these bitplanes, you enlarge the number of bits per pixel available for specifying a color. With four bitplanes, for instance, you can index into a tabic of2x2x2x2 = 16 different color registers. Each such register uses three four-bit segments to specify the red, green, and blue components of each color. Sixteen possible values for each (binary 0000 to 1111), multiplied by three segments, produce the Amiga's 4096 colors.
With lo-res width images (320 pixels), the Amiga allows as many as five bitplanes for the display, which enables a total of 2**5 = 32 colors on screen simultaneously. For hi-res widths (640), the hardware can accommodate only four bitplanes.
However, if you stick to the lower res, the Amiga also features a special "hold and modify" (HAM) mode which uses six bitplanes to permit all 4096 colors on screen at once.
Two of the six bitplanes are used to select one of four modes for each displayed pixel. In mode zero, the pixel color is determined by the color register value indexed by the other four bitplanes. But in modes one, two, or three, those bitplanes are interpreted as providing just blue, red, or green value, with the rest of the color "held over" from the previous pixel.
It Slices, It Dices Those two components of the Amiga screen display a set of bitplanes on one hand, and a sequence of color registers on the other provide the basic ingredients for Butcher's assorted forms of image manipulation. Let's take a big breath and try to go through as many features as possible.
Some of Butcher's operations act on all the bitplanes of the image at once. As we have seen, you can transform an image from any resolution to any other. You also can go from HAM to lo-res non-lace, and back. The Reverse utility changes the image's orientation from right to left. Flip turns it upside down.
If you select Format, you can display any image in a screen of any other resolution (as contrasted with changing it to that resolution). For instance, you can view a hi-res image in a lo-res screen. Since not ail of it will be visible at once, you can scroll using the cursor keys. In Format and elsewhere, Butcher makes appropriate provisions for overscan images.
You can use the Change Depth feature to add or delete bitplanes within the constraints of the Amiga hardware.
Or, you can use Slice Plane to display any subset of your image's bitplanes, which creates many interesting effects.
If you load in a Spare image, a number of other tricks becomes available. For instance, you can swap bitplanes between your main and spare images. Or, you can select one particular color, and Merge the spare into the main picture everywhere that color is or everywhere it isn't.
Here, as with most of Butcher's transformations, extensive use of the Amiga's special blitter chip speeds up the operation. Usually, it is done in less than a second. In most cases, the program allows you to Clip a rectangular subsection of the image. As long as such an area is defined.
Butcher restricts its transformations to that region, speeding it up even more.
It Makes Julienne Fries As the Merge functions show, Butcher can transform the contents of your images' bitplanes in addition to shuffling them around. It provides a Draw menu with many of the basic functions you'd expect: straight and freeform lines, solid and outlined rectangles and ellipses, generalized polygons, fills, airbrush, and so forth.
The program assumes you have access to more powerful tools of this sort elsewhere. More unusual is Butcher's ability to make pixel-by-pixel transformations depending on the color register value addressed by that pixel.
(For this reason, most of the program's operations cannot be performed directly on HAM images.)
Foremost is its edge-finding capability.
Butcher uses a Sobel operator for "edging." The color of each pixel is compared to that of its immediate neighbors. If the difference in color exceeds a threshold, that pixel is highlighted as part of an edge.
The program uses a color's intensity for these comparisons, which it calculates as the simple sum of the red, green and blue segments of the color register value. There are other ways of calculating intensity; color is a mysterious thing. Butcher's approach is adequate for most purposes.
The Edge requester allows you to select the degree of "edginess" you want to detect, and the pen and paper colors for drawing it. You can even write the edge directly on the image.
Beside creating nice effects, it provides a chance to experiment with one of the fundamental techniques in the artificial intelligence analysis of images.
Butcher doesn't use the blitter for edge-detection, however, and takes nearly 30 seconds to "edge-ucate" a 320 x 200 pixel screen. This represents an almost threefold speed-up over the first version of the program.
You are also given flexibility in the Filter utility, which allows isolated groups of pixels of different sizes and colors to be deleted. A Screen command provides the ability to do something called "sample ordered dithering," and Diffusion provides one of many variations on half-toning.
One of Butcher's most powerful tools produces what are called Mosaics. In the simplest version, it subdivides the image into squares of four pixels, and shades each square with one of the original colors. The result is a "tiled" effect, as the image is reduced to one- quarter of its original resolution.
Butcher 2.0 takes this concept much further. You are given the ability to design whatever size and shape tile you desire, overlapping or separated.
Indeed, you really can do "julienned" strips in a late-night paroxysm of image processing madness.
Make Me A Palette So far, we have concentrated on operations which alter an image's bitpianes. Now let's look at Butcher's many tools for manipulating the color register table. The most important is the Make Palette requester. ("Palette" is Butcher's term for a particular set of color table values.)
Butcher maintains two palettes in addition to the one loaded with your image. This allows you to save a copy of the original in case you become unhappy with your changes. Any of the colors in the image can be selected by clicking on samples in the requester, or on a pixel of the appropriate color in the image.
Sliders control changes in the red, green and blue components of a color.
Butcher also breaks color down into hue, saturation, and value components, which you can change as well. "Hue" refers to a color's position in the spectrum, which Butcher represents as a point on a color wheel. "Saturation" represents the vividness of the color, and "value" its degree of lightness.
There are tools for changing the whole palette. These alter the red, green, blue, saturation, value, or contrast of all colors in the palette simultaneously.
There's even more. Clicking on Neg or Cmp inverts a color value in different ways. Pck causes all the pixels in the image of a selected color to flash in red, which is often useful.
A toggle switch brings up a selection of color cycling tools, permitting four ranges, each at a separate speed, Perhaps the most powerful function on the Palette requester is the ability to sort the color table according to intensities. The image does not change, because after Butcher rewrites the pixels for each color, it makes sure the new color register they index has the proper value.
And That's Not All If you would rather sort the palette according to the frequency with which each color is used, use the Histogram function. This tool constructs a bar chart showing the frequency of each color's use. A click of the mouse button replaces the bar chart with a line graph capable of showing the red, green, blue, hue, saturation, and intensity histograms of the image (or a subsection, if you're using Clip).
Ydu can rewrite all the pixels of a given color in other ways. Butcher lets you Exchange, Merge, and Blend different specific colors. If you want, you can direct the program to print the color statistics and graphs that Histogram generates.

Image, another artificial intelligence technique. Density Slice lets you highlight up to four of these segments.
Butcher provides a host of other operations for manipulating the values in the color registers. You can render your image in black-and-white, or Tone it with the hue and saturation of your choice. You can Negate or Complement the whole palette at once.
There are controls for False Colors, Pseudo Colors, and Antiqueing.
With Segment Color you can restrict the colors displayed to a specific range around a particular hue, saturation, and value. Band enables you to represent the red, green, and blue components of your picture as intensities of gray. If you have a laser printer, or want to make a T-shirt from an image, Butcher provides all you need for color separations.
Some of Butcher's other useful features include the ability to print out Clips, as well as the whole image (either as is or expanded); an extensive use of keyboard commands to parrot or augment the mouse; and a number of memory conserving options for those with limited RAM. The program also lets you check on how much memory is available, a nice touch.
Order Now, While Supplies Last There are many more features I could discuss, but a litany of this kind can only go on for so long. If I've managed to create the impression that the program provides a rich grab-bag of image manipulation tools and techniques, then I'm satisfied.
The program is amazingly inexpensive for what it does, and can be upgraded for not much more than the cost of a disk, shipping and handling. I find it heartening, in these mercenary times, that some people can still provide a quality product at a reasonable price.
There are things 1 would do differently. I suspect the tools could be more clearly organized. And although the new booklet has been greatly expanded, I would appreciate a more detailed discussion of the color concepts underlying its features.
Instead of representing each hue as a point on an imaginary color wheel, it would be nice if Butcher actually showed that wheel on the screen, or better yet, a color solid. This would help users get a more intuitive grasp of the web of color they are transforming in their images.
There are the inevitable inconveniences and bugs. Butcher has the kind of Undo feature you would expect, but it is often needlessly "no-opted" by selections irrelevant to the image.
When moving from one resolution or formal: to another, you will lose the spare image without warning. And repeated use of the Format controls can cause the program to "lose" memory, leading me once to Mr. Gum.
As the manual points out, many of the features of Butcher 2.0 have resulted from comments and suggestions prompted by the original program. I can only hope that this process goes on. If you have any interest in Amiga graphics, you should get Butcher.

In AC V3.3,1 reported on a bug and an upgrade policy for Deluxe Paint II. I have since received a communication from Charlotte Taylor of Electronic Arts regarding the information I provided.
By John Steiner Bug Bytes The Bugs & Upgrades Column In her letter, she comments on that report.
1. The article implies that disks that have the DH: button (as
opposed to those that have a DHO: button) will crash the hard
disk. Their quality control department wants to assure readers
that those disks are functioning properly.
2. Electronic Arts will replace any problem disk, regardless of
the problem, free of charge within the first 90 days of
purchase (a copy of the dat receipt must accompany the
request). After 90 days, Electronic Arts will replace the disk
for a charge of $ 7.50.
3. If readers have any question about the status of their Dpaint
II disks, they should contact customer service at (415)
Regarding the first item, the original bug report was included in my column because I received three separate reports from three different individuals. The second item is a matter of Electronic Arts policy. Either my original source was incorrect on that upgrade policy, as earlier reported, or the policy was deviated from in that instance.

However, according to reports found on information services, the program has some rough edges. Loading a font without text on in the frame will cause a guru error. The default font doesn't always change when selected via the requesters, There also seems to be a problem with fonts larger than 20 points remaining active for more than a few letters. Several users have reported that document size must be set to 8 by 11, rather than the default size of 8.5 by 11.
If the smaller size is not selected, the program will guru.
Professional Page, Gold Disk's top-of- the-line desktop publishing software, has a problem with some defaults.
Among other default items, the default box function does not seem to work right. To work around this problem, put a box on the pasteboard, set all its default characteristics, and use "clone box" to create a box with the correct attributes each time you need a new box. You will have to resize the new box as required, but it is easier making major changes in the box after using the Create box function, which uses the default box attributes. If you have tabs set in the box, this work-around is especially useful. The technique can be extended to several different box types, which can be stored on
When a new box is needed, just clone the box of the desired type.
According to information found on a Genie posting by an Amiga user, Softwood File II (also known under the name MiAmiga File II) has a bug in the PAGE SETUP submenu of the PRINT menu. At the requester that lets you specify print environment options for printing labels, there are OK and CANCEL gadgets. Neither gadget seems to work properly under some conditions.
Both gadgets do work, but only on the very right of the OK gadget, and the extreme left of the CANCEL gadget.
Many people have been complaining about the Amiga 2000 clock gaining or losing time (mostly gaining). It seems that quality control may have slipped up, and let a batch go out without having clocks set to keep time accurately. If your A2000 gains or loses time, you can adjust the clock yourself, though it takes patience, and probably several attempts before it is right.
Take the cover off your A2000, and look for a small yellow square in the front center of the motherboard. Use a jeweler's-sized phillips screwdriver, and turn the screw counterclockwise inside the yellow square to slow the clock down. You will have to turn it in small increments and test it for accuracy. You can get close by using the digital onscreen clock while comparing it to a digital watch. When the seconds click by seemingly in unison, you are getting close. It may take a few tries to set it exactly right. Reset the system date to the correct time and date when you're through adjusting
the clock. Thanks to Frank, known also as Minotauron People Link, for this suggestion.
Amiga 1000 owners who are having intermittent problems loading Kickstart and or Workbench may find the problem cured very simply. The Amiga goes through several diagnostic tests upon power-up. If the screen remains one color, and refuses to boot Kickstart or Workbench, this indicates a defect was detected by diagnostics. A RAM problem is usually indicated by a green screen. Though it is not always the problem, one solution to try before taking your Amiga to the service center is to reseat and check connections to the 256K RAM daughterboard that holds Kickstart software.
In many cases, Amiga 500s that have trouble booting Workbench can be repaired by simply reseating the Fat Agnes chip. One user has reported that Commodore has installed a hold-down assembly that keeps the chip solidly in place on the latest production of A500s.

- AC- The Amiga seems to be moving into the third phase of its
musical growth curve. In the first phase, we had composition
programs like Music Studio, DMCS, and Sonix programs allowing
you to create music on the computer and play it back via
internal sounds and external MIDI instruments.
Phase two brought us real-time MIDI recording with packages like SoundScape Pro MIDI Studio, fimigaNotes by Rick Rae CIS 76703.4253 HMH Dr. T's KCS, Dynamic Studio and Music-X. Granted, there has been some overlap of these two phases, but the trend has been toward more and more capability.
Now', we're starting a new chapter. The Amiga has been provided with a reasonable number of programs directly involved in composition and performance, and manufacturers are now turning to support items like patch editors, patch librarians, sample editors, and sound creation tools. This month we'll take a look at one of these new tools: a patch editor librarian.
Back in the days of modular analog synthesizers, you kept track of your patches with a notebook or an index card box. When a string sound was needed, you'd dig through your notes and use patch cords to connect the various modules together (hence the shorthand term "patch," meaning a sound setup) and tweek the knobs until you found what you wanted.
With the advent of programmable synthesizers, the need for written notes has gone. We can store patches in the synthesizer's memory or on removable cartridges. But if you're using a computer to control a network of MIDI synthesizers, it makes more sense to use the computer for patch storage. This is the function of a librarian to store, catalog, and retrieve synthesizer patches using your computer's disk drives.
Along with the fancy new synthesizers came a reduction in the number of knobs to tweek. Many modern synthesizers have only two knobs a master volume control, and what is often called a "data entry slider."
Rows and rows of buttons select the function you wish to edit, the slider changes that value, and the results arc shown in a small display window.
Although this is great for cutting costs and improving reliability, it can make creating a new sound, or even editing an existing one, a real pain. The patch editor helps out by allowing you to do the editing with your computer, providing a much larger "window" into the synthesizer. A comprehensive patch editor might even provide graphic editing and features that the synthesizer itself doesn't even support.
DX-Heaven from Dr. T's Lots of people are very excited about Dr. T's decision to support the Amiga, and for good reason. Dr. T's has been around for quite some time and supports the C64, C128, IBM PC, Apple II, Macintosh, and Atari ST. As with the release of WordPerfect for the Amiga, many feel that Dr. T's has helped "legitimize" the machine, which in turn will convince other companies to develop software and hardware for the Amiga. Of equal interest to those of us who must use the software is the fact that Dr. T's sells a quality product.
If you have a synthesizer, chances are that Dr. T's has a patch editor librarian for you. They currently support over a dozen instruments, and more are added every day. I've just finished an in-depth investigation of DX-Hcaven, developed by Caged Artist and distributed by Dr. T's. This (continued) is a fully functional patch editor librarian for the Yamaha DX-7 and TX- 7 synthesizers and TF1 modules. Since the niggly details would only be of interest to owners of these machines, we'll take a look at the general layout, which applies to all of Caged Artist's editors librarians.
Nearly all the comments 1 will make about DX-Heaven apply to the entire line.
First, the bad news. If you expect flashy or fancy graphics, you're going to be disappointed. DX-Heaven is a direct port from previous versions, and it shows. Pulldown menus are not supported at all, gadgets are for the most part hidden, and the graphics are minimal. Figure 1 is a typical DX-Heaven screen.
Now for the good news. Since the Amiga version of DX-Heaven is a direct port, you'll feel right at home if you're already used to, say, the C64 version. It could be a great advantage for MIDI musicians moving up to the Amiga. The lack of pull-down menus makes sense because they simply aren't needed. And most importantly, DX-Heaven works, and works well.
The User Interface One of the nicest things about DX-Heaven is it supports both the keyboard and mouse almost completely. If you're a mouse addict, you can do almost everything with the rodent. Each menu item is actually a hidden gadget, and you simply click on the name of the function to select it. A huge data slider (you can see it to the left of the screen in Figure 2) can be used to enter every parameter. (Even the . F , , „ , , , , FIGURE THREE individual letters of each patch name, if you're that much of a masochist.) The only thing requiring Using either input device all the time the
keyboard is the file requester, and would be ludicrous. Rather, the then only if you are saving a com- beauty of this scheme is its flexibility; pletely new patch bank to disk. You can use whatever mix of mouse Conversely, if you have mouse-o- phobia, nearly everything can be done from the keyboard. All the menu functions are represented by function keys, and are dearly labeled on each screen. You can move around on the edit screens using the arrow keys, then enter new values directly for each parameter, or increment decrement them using the keypad and keys. About the only thing you can't do
without the mouse is graphic envelope editing, although you can of course set the envelopes via numeric entry.
And keyboard you find most comfortable. 1 like the graphic envelope editing capabilities, and the direct access to all parameters by simply- clicking on them. But I find it faster to key in completely new parameters from the keyboard, rather than slide the mouse around.
You might like a different combination, but that's the point. DX-Heaven will accommodate you. A high score for flexibility in this area.
As long as we're talking data entry, I should mention that you don't have to specifically "grab" the data entry slider to move it. Instead, you can click a parameter and then, holding down the left mouse button, move the mouse vertically toward the slider's knob. As soon as the mouse is directly across from the knob, the knob will begin tracking the mouse, allowing you to make rapid changes in values without having to fiddle with the slider.
Figure 3 shows the graphic envelope editing screen; a similar screen is available on Caged Artist's patch editors for other synthesizers.
The DX7 has one envelope for each of its six operators, The active envelope is shown with solid lines, with the other envelopes shown as dashed.
The small boxes mark the endpoints of the waveform segments; you can grab these with the mouse and drag them wherever you want them (within the limits of the synthesizer, of course). This is an excellent approach for fast approximations of new sounds. Once you get close to the graphic editor, you can switch to the edit screen (Figure 2) and fine-tune each envelope parameter individually.

Another nice touch is what Caged Artist did with the right mouse button.
As I mentioned earlier, there are no pull-down menus. Since the right button isn't needed for that, it is instead used as an "audition" button.
Any time you click the right mouse button, the synthesizer you are programming plays a note. Moving the mouse to the right produces a higher note, to the left a lower one.
Moving it toward the top of the screen produces a higher MIDI velocity (normally a louder or "brighter" tone), whereas moving towards the bottom produces a lower velocity. What's more, you can apply modulation by moving the mouse up and down on the screen with the left button depressed; this modulation can simulate any one of several controllers, such as the modulation wheel or aftertouch.
Combined, these functions are useful for fine-tuning a voice. Instead of reaching over and playing the instrument keyboard, you can keep your hands on the mouse and computer keyboard, and your eyes on the screen.
I won't say anything else about patch editing, since the details would only apply to people who own six operator Yamaha synthesizers. Suffice it to say that the editing facilities are well- designed and easy (yes, even intuitive) to use.
The manual I received was the Atari version, since the release version wasn't quite ready. The folks at Dr. T's tell me the new manual will be ready by the time you read this. It will be a "split" booklet which covers both the Amiga and ST versions. I should have it by next issue's deadline; if that's the case I'll comment on it briefly. I do hope they don't "tone down" or "serious up" the manual; 1 rather like the conversational approach of this version. 1 was especially fond of some of the obvious hacker comments, such as 'The DX format involves a serious kludge, a series of undocumented
simulated button pushes, which does, however, seem to work..." Patch Management Today's synthesizers deal with more than one patch at a time, arranged into banks. For example, the DX-7 has two 32 patch banks, one in internal RAM and a second on a removable RAM or ROM cartridge. Arranging the 32 voices you need for tonight's jam or the band's first set can be a pain using the synthesizer alone; with DX-Hcavcn it's a joy. The program will load up to eight banks (256 voices) simultaneously. You can copy a voice from one position in any bank to any position in same or any other bank, move a
voice from any position to another position within a bank, or exchange any two voices. A copy of a bank's patch list can be quickly dumped to the printer and carried to your practice session, so the group can verify the order of the songs, or so you can file your patch lists in a notebook (helpful if you have thousands and thousands of patches).
Other Goodies As 1 mentioned in the opening, a really good editor librarian will often provide you with features the synthesizer doesn't even support. In addition to voice storage on disk and graphic envelope editing, DX-Heaven will randomly create patches. These machine generated patches are a good start toward a new sound; DX-Heaven will sometimes try something you never would, and the result is an "oh, that's interesting..." sound, which you can then tweek to your satisfaction.
Since a totally random patch would in all probability be useless, DX-Heaven lets you specify what parameters you wish to randomize. The selections from a single parameter to every one in the book are totally up to you, and define what Caged Artist refers to as a "Randomization Mask." Once you've set up a mask (by clicking the "Rand Mask" gadget and all the parameters you want to randomize), simply clicking "randomize" will generate new random patches, one per click. It's very easy and fast. Click "randomize" and play the new sound using the right mouse button; if you don't like what you hear,
click "randomize" again. A particularly nice touch is that you can save your masks to disk, and even define one as the default, so it loads automatically, DX-Heaven also comes with over two dozen banks of patches for the DX TX family (there are 32 patches per bank, so that's over 750 sounds). 1 have no doubt that the other librarians also include a similar treasure chest. On startup, DX-Heaven loads a blank patch bank called IN1TBANK.TX7 from the current directory; if you don't mind naming an actual bank this, you can have DX-Heaven come up loaded and ready to run with 32 of your favorite
In addition to its functions as a patch editor librarian, DX-Heaven also pulls its MIDI weight in other ways. For example, the DX-7 can receive data on any channel, but can transmit only on channel one. DX-Heaven's "Rechan- nelize" option allows you to change all channel messages reaching the Amiga's MIDI IN port to the channel of your choice at the MIDI OUT port.
"Solo" allows the channel voice messages for one selected channel through, blocking all others. These functions can come in particularly handy in a larger MIDI system, especially when you are playing manually or using a dedicated sequencer.
Gripes and Gotchas DX-Heaven is protected with a key disk scheme, which means you can make working copies or move the program to your hard drive, as long as you don't mind plugging in the master copy once during startup. Sadiy, if you click the cancel gadget of the disk requester or accidentally name your working copy the same as the master disk, DX-Heaven will promptly crash your machine. I suppose this approach is satisfactory for a C64, but it is extremely heavy-handed for a multitasking machine.

EaseWare Suggested retail price 25 Beiair Rood $ 199.00 Wellesley. MA 02181 617-237-2148 Amiga Is a registered trademark of Commodore-Amiga The reason I know this is from a little glitch in the copy of DX-Heaven 1 received; several of the data file icons which can be used to start DX-Heaven want a disk named "DX HEAVEN", with a space. The disk is in fact named "DX-HEAVEN", with a dash.
While trying to get these files to load, I crashed my Amiga twice.
The folks at Dr. T's tell me they found this misnaming shortly after they sent out my copy of DX-Heaven, and that the version actually being shipped has the correct icons. If you happen to get one of the old disks, however, you can use the WorkBench Info option (not the CLI Info command) to reset the icons on your COPY of the DX- Hcavcn disk. Or, you can do what 1 did for a temporary fix: ASSIGN DX- HEAVEN: "DX HEAVEN".
Other than this, and the rather harsh slap in the face you receive if you try to back out from the CP disk requester, I found DX-Heaven to be well written and easy to use. It seems to be a very solid program, and should be worth the price to anyone who does a lot of patch programming or shuffling. If you're not looking for superficial flash and fancy graphics, and if you just want to get the job done, it comes highly recommended.
• AC- It Is To Blush" Department ii If you have any doubt that
Murphy is alive and well, become a writer. Even if you manage
to catch all your own silly mistakes with the help of spelling
checkers, friends, and the publication's editors, there are
still plenty of places for Murphy to work his magic. In the
last few issues a few "bugs" have slipped through some of them
my fault, some of them no one's and I felt I'd better make you
aware of them.
V2.12 In last year's final installment of AmigaNotes I talked about the changes which affected audio on the new Amigas. Since most MIDI interfaces connect to the serial port, I pointed out the pin and voltage changes on the serial port and how they would affect the operation of MIDI interfaces. What I didn't mention was that the parallel port has also changed, which has an impact on parallel port based audio digitizers.
] haven't had an opportunity to look at the schematics for the new machines, but I'm told that three pairs of pins have been swapped on the parallel port, in addition to the change of gender. As with the MIDI interfaces, I called the affected manufacturers to see how they're dealing with the changes.
Dave Reinkc of Applied Visions (makers of FutureSound) tells me they are currently supplying an adapter which changes the gender of the port and moves the power pin as needed; you can purchase one for S24.95. Work is proceeding nicely on a new version of FutureSound for the 500 and 2000; it is expected to retail for S199. If you'd like more info, you can call them at (617) 494-5417.
This is a new number, as Applied Visions has recently moved; the new address is at the end of the column.
Anthony Wood of SunRize Industries says they've taken this opportunity to completely redesign Perfect Sound. It now uses a faster ADC design, is housed in a box the size of a cigarette package, and uses one potentiometer to control the gain of both stereo channels in tandem. The price is the same as for the older design: S89.95. SunRize will also send you a new digitizer in exchange for your older unit and S25.00. You can reach them at (409) 846- 1311 for further details.
In addition to this omission, I made a flat-out silly mistake. I commented "... you can lay FILT's small window over your Pro MIDI or DMCS or whatever screen..." Wrong, wrong, wrong. FILT does exist in its own window, and you can indeed lay this over Pro MIDI's window. However, DMCS uses its own screen, and FILT therefore cannot be overlayed. This applies to many other music programs as well.
There seems to be a conspiracy to prevent AC from properly printing a MIDI interface comparison chart. The first one we printed (AC V2.1) was hopelessly garbled, and I even warned you not to rely on that chart when we printed the updated version. Unfortunately, the updated chart was garbled as well! The "NOTES" column should be last, not first, and all entries in the column are one line lower than they should be. There are a few new MIDI interfaces available and I'll be doing another comparison in a future issue; maybe the third time will be the charm.
V3.1 An entire section somehow dropped out of existence in my discussion of digital synthesis techniques.
The loose ends melded together so seamlessly that nothing seems amiss until you realize that the result is so much gobbledegook. The corrected text doses out this month's column.
RESYNTHESIS Resynthesis is a term for one of my pet approaches. It combines two techniques; Fourier analysis and additive synthesis.
Fourier analysis is basically the "flip side" of additive synthesis. Instead of combining sine waves to create a final product, Fourier analysis breaks a complex waveform down into its component parts.
With resynthesis, we analyze a recording of an existing sound, giving us a set of sine wave frequencies and amplitudes. These waves are then put back together, using additive synthesis, to recreate the original sound.
The advantage of this approach is one of information density. Many.of the components of the original waveform may be left out without adversely affecting the resynthesized version. And, once you've broken a sound down into its components you can play games with it invert envelope profiles, swap or substitute harmonics, and so on. The final product doesn't have to sound anything like the original.
SUBTRACTIVE SYNTHESIS Subtractive synthesis works backwards from additive synthesis (but in a different backward way from Fourier analysis...have 1 lost you yet?). With additive synthesis, we combine simple sine waves to create a complex output. With subtractive synthesis, we start with a complex waveform, and remove what we don't need.
This technique was most often used on the older analog synthesizers. Sonix is one of the packages which allows you to experiment with this approach on the Amiga. Start with a harmonic-rich waveform like a sawtooth, then use the filter to remove some of the upper order harmonics. This technique can be used to create credible string and brass sounds with a minimum of effort, its primary failing is that it is limited in the sounds it can produce; realistic acoustic pianos and plucked strings, for example, are particularly difficult to recreate. (Sonix bypasses this problem by giving you several
synthesis methods, including freehand drawing, which you can combine to create the final product.)

The Command Line by Rich Falconburg Last issue we learned to
use the DIR command to examine the contents of a disk. While
DIR is useful, it doesn't provide us with much information
about the files. We can determine which ones are directories,
but that's the sum of it. Many times it's helpful to know the
size and creation date of a particular file. The LIST command
will do this and more. We'll continue with the devs printers
directory for this example. Set your default to this directory
and then type LIST.
1 LIST Panasonic_KX-P10xx starnxlO CBM_MPS1000 Imagewriterli generic sg10 20:29:54 0kimate_20 Epson_JX-80 Epson HP LaserJet PLUS 4024 rwed 17-Apr-87 03:39:29 3492 rwed 17-Apr-87 03:39:41 4768 rwed 17-Apr-87 03:39:48 6956 rwed 17-Apr-87 03:39:52 1088 rwed 17-Apr-87 03:39:55 3504 rwed 14-Aug-87 5848 rwed 17-Apr-87 03:40:14 5926 rwed 17-Apr-87 03:40:25 5364 rwed 17-Apr-87 03:40:29 6244 rwed 17-Apr-87 03:40:33 The first column is obviously the file name. The next column is the file size in bytes. If there's nothing in the file or it was improperly closed, this field will say "empty." A directory
will have the "Dir" designation in this field. The next column is the protection field. The date and time in the next two columns indicate the creation or modified date and time. So what's this protection field all about, you ask?
Currently, not much. Although the field indicates that each file allows read, write, execute, and delete access, the only bit that's used in the present release of AmigaDOS is the one for delete. Let's say you have a Panasonic printer (so I'm biased). To prevent that printer file from being deleted we can set the protection bit for delete to deny that ability. Here's how: 1 PROTECT Panasonic KX-PlOxx rwe 1 LIST Panasonic KX-PlOxx Panasonic_KX-P10xx 4024 rwe- 17-Apr-87 03:39:29 The dash where the "d" used to be indicates that delete access has been denied. If you attempt to delete a file so
protected, the message "Not Deleted object is protected from deletion" will be displayed. You can change any of the bits by including or excluding that letter from the PROTECT command. Notice that I checked only this file by providing LIST with the file name. Try this with DIR. No worky. We can use LIST to display only specific information, such as the file name. If you hate typing or you're just lazy (like me) you can use "wild card" substitution. There are no Jokers here, but it means the same thing. Wild cards can be used to tell the system to match certain parts of the input string and
substitute the rest of the name where the wild card is.
To display all of the Epson printer files enter it this way: 1 LIST P Eps 7 Directory 'd(1 rdevs printers epsoo ?' On Sunday 06- Mar-88 Epson_JX-80 5928 rwed 17-Apr-87 03:4025 Epson 5364 rwed 17-Apr-87 03:40:29 2 files - 26 blocks - 11292 bytes The "P" informs the LIST command to use the following pattern. Some of you arc asking "What's this number, question mark stuff? What happened to the asterisk?" For those of you who don't know, a fair percentage of computer operating systems use the asterisk (*) as the "match anything" wild card. AmigaDOS, on the other hand, uses the two characters
shown above to perform the same operation.
'That's because the asterisk must be used to preface certain special characters, right?" Nope. Not with this command. Wc use the single quote (0 for that. And again, to use the single quote in the name, enter it twice (").
Here's a list of the various special characters that the LIST command uses for wild card operations: 7 Match any single character % Match the null siring p» Match zero or more occurrences ol o where p is any pattern ol characters p1|p2 Displays if pattern 1 (p1) or pattern 2 (p2) match () Groups patterns together As mentioned, combining the number sign and question mark together, " ?", informs the system to match anything.
We use the parenthesis to group combinations together. Use the question mark alone for single characters such as: 1 LIST B7LL This would find Ball, Bell, Bill, Bull, B2LL, etc. For multiple letters use the pound sign.
1 LIST B? L This would find all the examples above as well as BA, Bl, BS, B4LLL, etc. To narrow the search requires different combinations of the various special characters. The percent is used for empty strings. The vertical bar (I) provides a logical OR. Following arc some examples to help you grasp the concept.

informs the LIST command that a search template follows. The S
(string) option is useful if you're looking for filenames with
certain characters in them. Let's say that you know there's a
file with the word "old" in it somewhere, but you're not sure
of the rest of the name. We can use the following syntax to
1 LIST S old Tough, huh? This will display names such as OldBackup, ThisOldFile, GoldStrike, and Mountlist.old. To get a fast listing we can limit the display to just the filenames by using the QUICK option as in: 1 UST QUICK (You can't shorten this one like the string and pattern options.) If the files were created or modified within the last week, AmigaDOS will insert YESTERDAY, TODAY, or the day of the week into the Date column. If you prefer to see the actual date stamp, enter the following: 1» UST DATES Likewise, if you don't want any dates shown enter it as: 1 LIST NODATES This also
has the effect of suppressing the Time stamp. The Date field may be put to good use with two other options. SINCE will display files created or modified after a given date.
UPTO displays files created or modified before a given date. Any of the following forms are valid (both options must be spelled out as shown): 1 LIST SINCE TODAY 1 LIST SINCE MONDAY 1 LIST SINCE 18.DEC.fl7 1 LIST UPTO YESTERDAY 1 LIST UPTO WEDNESDAY 1 UST UPTO 5*AUG-06 Now Open In Texas!

I'm sure you've been wondering how to get a directory listing to the printer.
There are a number of ways; one is provided by the LIST command using the TO option. For example: 1 UST TO PRT: You've probably guessed that we can send the output to a file or any known device using this method. Do so by substituting PRT: with a file name or other device specification. There's one more option that's really only useful to programmers or someone familiar with the disk structure. This is the KEYS option. When included in the command line, the block number for the file header or directory is displayed.
The number is printed inside brackets between the file name and file size. If you use the LIST command often, you may encounter something like this: 1 UST dfl: p (%|dlskX7|%)Jnlo Directory ’dfl:* on Saturday 19-Mar-88 .info 35 rwad 27-Feb-88 21:24:32 diskl.info 633 rwed 27-Feb-88 11:34:18 : Hard Disk Icon disk2.info 618 rwed 27-Feb-88 11:34139 : Hard Disk Icon - alternate image Disk.info 1098 rwed 27-Feb-88 21:16:04 4 files -12 blocks used The colons (:) under the file names above indicate that a comment is attached to the file above it. Because this field is optional, not all files have
comments. The FILENOTE command creates a comment in this manner: 1 FILENOTE diskl.info ’Hard Disk Icon" (If the comment field contains spaces it must be enclosed in quotes. The maximum length is 80 characters.)
Manipulating Files and File Contents We'll come back to LIST from time to time and you'll begin to get a feel for its capabilities. I prefer it to the normal DIR command so much that I swapped the names on the two. Yes, my friend, you can rename any AmigaDOS command to whatever you prefer. A note of caution here: if a program expects to find a command by its standard name and you've renamed it to something else, you may experience problems. The most vulnerable of these is the RUN command. The best way to avoid the problem is to COPY the command to a new name. Both commands may be used with the
optional qualifier TO.
RENAME also allows the use of AS.
Here are some examples of both methods (Current Directory is ROOT): 1 RENAME C DIR C TEMP 1 RENAME C LIST TO C DIR 1 RENAME CTEMP AS C UST 1 RENAME Clock C Clock 1 COPY C EXECUTE C @ AMIGA DUAL 3VY' DISK DRIVES 100% Computable with Amiga 500, 1000 & 2000 Computers

1 COPY CDIR TO Cis 1 COPY Clock 01 The standard device, directory, and file name specifications may be used with either command. Notice the last example in each group. The operations are nearly equivalent. The difference is that RENAME moves the file to another directory. It has the same effect as copying the file to the new directory and then deleting the file in the source directory. It is, however, device limited. You can't RENAME to another device to move the file. You must use COPY instead.
Here, I introduce the second Commandment of CLI: BEWARE OF DUPLICATE NAMES!!
AmigaDOS does NOT prevent the COPY command from overwriting existing files of the same name. In the example above, if a file named "Is" already exists in that C directory, the copy command will replace it with a duplicate of the DIR command now named "Is". Only the protection bit will prevent it. This is not true of the RENAME command. If you try to rename a file to one that exists you'll see the message "Can't rename oldname as newname ". That's why I renamed DIR to TEMP first.
I n previous examples we've been working with specific files. It's possible to perform operations on the directory as a whole. For example, to copy the C directory to a directory on a disk in DF1: we use the follow- ing: 1 COPY DF0:C DF1:C If we set our default directory to the one we're copying from, we can drop the source specification and use the normally optional TO qualifier.
1 CD DF0:C 1 COPY TO DF1:C Each example requires that the destination directory exist. Because the command directory has no subdirectories, everything goes as planned. Copy the devs directory to a scratch disk and see what happens.
All the subdirectories are left behind.
To get the COPY command to pick up the subdirectories, use the qualifier ALL like so (devs must exist): 1 COPY DFOidev* DFLdevs' ALL Normally, the file names are displayed as they're copied. To suppress this display, use the QUIET qualifier. Both QUIET and ALL may be used with the DELETE command as well. DELETE is similar to COPY but works in reverse. It removes files and directories. Another difference is that DELETE, used without options, won’t delete a directory unless it's empty.
WARNING!! When the ALL qualifier is used with the DELETE command, the contents of the directory and all subdirectories are deleted. If this specification is used: 1 DELETE DF1 :Devs ALL (continued} Workbench WBExtras ~WBE TRA5 by Peter Dunlap Isn't it time you got the most from your Amiga?

Examining File Contents Files used by the Amiga are of varying types. The primary distinction is between Binary files (files of binary data or program files) and Text files (files of standard ASCII text). Program files, such as those that make up the command directory, can be RUN and are known as "executables."
Some files are binary but will not run and AmigaDOS will return the error message "file is not an object module."
This same message will occur if you attempt to run an ASCII text file.
We'll talk more of executables later when we get to the RUN command and background operations.
A text file simply consists of standard text similar to what we type when we issue commands at the CLI prompt.
Lot's create a simple text file using a command we're already familiar with.
Enter the following and I'll describe what has happened.
1 COPY * TO DemoFile I’ve been around and tried the rest if you ask me, Amiga's the best.
To terminate and close the file press CONTROL (the backslash next to the BACKSPACE key). In so doing, the CLE prompt will return. We've used a special file name reserved by AmigaDOS, the asterisk, and placed the information from that file into a text file called "DemoFile", Can you guess what happened? AmigaDOS uses the asterisk to identify the current console window. The information typed in the console window is copied to the file. It can be used for both Input and Output. Here we've copied the contents of the console window to DemoFile. It's a simple to create text files. We'll be getting
into some more sophisticated text manipulation next issue. Now, to look at the contents of our text file use the TYPE command.
1 TYPE DemoFile Ive been around and tried the rest ii you ask me, Amiga’s the best.
The Amiga uses several text files to control system operation. Let's take a look at one of these using the TYPE command. The S (script) directory contains a special file AmigaDOS uses every time the system is Booted. This is where we place instructions to customize our environment. Enter the command string below and examine the output (default directory is ROOT).
1 TYPE S startup-sequence echo ‘Workbench disk. Release 1,2 version 33.47“ echo ‘Use Preferences tool 1o set dale1 echo ‘ * if EXISTS syssystem path sys system add endif il EXISTS sysxittlilies path sys:utilities add endif BindDrivers LoadWb enddi nil: This is where the paths I mentioned last issue are defined. We'll learn more about the nature of the S directory and startup-sequence when we discuss the EXECUTE command.
TYPE displays the contents of any file.
If it's anything but a text file, however, you'll get some strange results.
You now have enough commands in your arsenal to examine just about everything on a Workbench disk.
You've learned about directories and files and several commands to manipulate both. Experiment and get comfortable. Next issue I'll explain what some of these directories are for and suggest ways to customize your Workbench disk.
¦AC- New Cli Window 4 C Reassigning Workbench Disks Without Rebooting by John Kennan If you own a single-drive Amiga, you are probably frustrated by the need for frequent disk swaps. One cause for the appearance of the dreaded disk requester is that much of the Amiga's operating system is disk resident. When you restart or reset your Amiga, you are prompted to insert the Workbench disk. When you insert a valid startup disk, it becomes the system disk. From that point on, whenever the Amiga needs to look something up, the Amiga will look for that disk. If the Amiga is looking for AmigaDOS
commands, printer drivers, or anything else, and the can't find them, the Amiga will try to check the needed information on the disk you booted on. If the system disk is not in a disk drive, a requester will ask you to reinsert the disk. As the owner of a single drive system, ! Found this an inconvenience at times; it necessitates frequent disk swaps. This article will focus on a solution to this problem which involves the use of AmigaDOS executable files to change system disks without rebooting. I will assume the user has some familiarity with AmigaDOS. If you have not used an AmigaDOS
CLI before, I strongly suggest you purchase an AmigaDOS Manual.
One way to avoid frequent disk swaps is to keep a separate system disk for each major application. For example, I have separate system disks for my word processing, telecommunications, and program development programs. If I want to use a different application, I just reboot on the appropriate system disk. Usually, if the application you are using is on the system disk, you can avoid the repeated appearance of requesters asking for disk swaps. Unfortunately, this is not a very acceptable solution to the problem. Frequently, there arc programs or data resident in memory. Rebooting the computer
loses everything in memory (except recoverable RAM disks). Besides, rebooting takes time.
The best solution would be to tell the Amiga you want it to start using a new system disk. Fortunately, AmigaDOS includes a command to make this possible: the ASSIGN command.
(continued) Open a CLI window and enter "ASSIGN". When ASSIGN is entered without any arguments, AmigaDOS lists current assignments, The typical output of the ASSIGN command looks like this: Volumes: Textcraft (Mounted) Directories, S Textcraftrs L Texrcraft:l C Textcrafhc FONTS Textcrafkfonts DEVS Textcraft :devs LIBS Textcrafklibs SYS Texfcraft: Devices: DFO PRT PAR SER RAW CON RAM The Amiga uses a system which looks for certain vital information to be held in logical devices.
What is a logical device? Let's say you wanted to take a directory of the disk located in your internal drive. You could type "DIR diskname" where diskname is the name of the disk, or you could type "DIR DFO:". DFO: is a physical device. When you refer to DFO:, the Amiga knows you arc referring to the internal drive. It doesn't have to know the name of the disk, because you've told it where the disk is located. A logical device is based on the same idea. C: is the logical device containing AmigaDOS commands. Given the results of the ASSIGN command above, if you were to type "DIR C:", the Amiga
would know you wanted the directory of Textcraft:C, because Textcraft:C is the current assignment for C:. This system was implemented to make it easy for the Amiga to find information regardless of its location, In the above example, the ASSIGN command revealed the current assignments (places where required information may be found) for the 7 logical devices in my system. These are:
• Use any IF Imoges, any resolution, any number ol colors

driver it will look in the logical device DEVS;. In the above
example, the DEVS: device has been assigned to the devs
directory on a disk named Textcraft.
Earlier, I stated the system of logical devices was implemented to make it easy for the Amiga to find information, regardless of its location. This is necessary because the ASSIGN command also allows us to change the assignments where the Amiga looks for information. For example, if I typed in "ASSIGN FONTS: Tcrminakfonts", the Amiga would search on the disk named Terminal in the directory called fonts every time it needed to load a new font.
This lets us reassign everything to another system disk.
Unfortunately, a lot of typing and disk swaps would be necessary to completely reassign to a new disk. Rather than do it the hard way, you can implement a Reassign command by creating a DOS executable file to do all the work for you. 1 have done just that with two listings included in this article. To implement an executable reassign function, you need to type both listings using a word processor or text editor. The files must be saved as ASCII text files, and copies of each file should be stored in the s directories on your various system disks. Thus, the listings should be saved as
S REASSIGN and S REASS1GN1. Once both listings are saved, you're ready to go.
To reassign to a new system disk, go to a CL! Window and type "EXECUTE REASSIGN". After a few seconds, the Amiga will prompt you for the name of the disk you want as the new system disk. Type the name of the disk, followed by a colon. For example, to reassign to a disk named Terminal, enter 'TERMINAL:" at the prompt. After a few seconds, the Amiga will request that you insert the disk named Terminal. If you insert the disk, the Amiga will proceed to reassign all the logical devices to the new disk.
Remember to give each system disk a unique name, or the Amiga will just reassign back to the original system disk.

Create temporary files, which are always placed in the T directory. By creating a T directory in RAM:, and later changing RAM: to the current directory, we can force the Amiga to write these temporary files to the RAM disk.
Later, when we change disks, the Amiga won't have to ask for the old system disk to access the temporary file. This also allows the program to delete the temporary file easily.
Next, AmigaDOS will move the file Reassignl and the command ASSIGN to the T directory of the RAM disk. Now the program changes the current directory to RAM:. The Amiga is now set up so once the user is prompted to insert a new disk, the program will not have to refer back to the old system disk.
Now AmigaDOS invokes the executable file Reassignl. The technique used here was described by Udo Pcmisz in AC V3.5. The line "Execute RAM:T Reassignl ?" Causes the Amiga to execute the file Reassignl. The question mark causes the Amiga to prompt us to enter the parameters required by the file Reassignl. If we look at the first line of Reassignl, we sec the line ".KEY Dname". This means the executable file is expecting a parameter to be used by the variable Dname. The net result is, when the user types "EXECUTE REASSIGN", the Amiga will eventually display a prompt for the parameter for the file
REASSICN1 by displaying "DName:". The user should type the name of the new system disk. AmigaDOS uses Parameter value substitution to execute Listing 2. This subject is described in the aforementioned article by Udo Pernisz and in the AmigaDOS manual within the discussion of the EXECUTE command. The net result is that the Amiga creates a temporary file in RAM:T which will have a name like Com- mand-0-T01. This file will look a lot like the file Reassignl.
The only difference between the two files will be that the new file will not have the line ".KEY Dname”, and the new system disk's name will be substituted for every occurrence of the variable DName .
At this point, AmigaDOS will execute the newly created version of Reassignl that is now in the T directory. This causes the Amiga to check first to see if the requested disk exists. To the user, this means a requester will appear requesting the new disk. If the disk is inserted, the Amiga will proceed to ASSIGN all the necessary logical devices to the directories on the newly inserted disk; otherwise it will just change the current directory back to the old system disk. At the conclusion of executing REASSIGNl, the Amiga will delete the T directory, eliminating the copy of REASSIGN1 and the
temporary file created by AmigaDOS.
If for some reason, you require a T directory in RAM:, you may want to change the last line of the file Reassignl to "DELETE RAM:T Reassignl RAM:T Assign". This will at least delete two of the unnecessary files, while leaving the T directory untouched.
The Amiga has now been reassigned to a new system disk.
If, you have copies of both these files on all your system disks, even a single-drive user will be able to move smoothly between the disks, minimizing the hassle of repeated disk swaps. If you maintain major application programs on separate system disks, Reassign will aid you in moving smoothly from application to application.
I must point out that there are difficulties with this scheme.
If a program is running before the REASSIGN file is executed, that program may still want to refer back to the old system disk, so an occasional disk swap may still be necessary. Another problem is this scheme does seem to confuse the Workbench environment. After Reassign has been invoked, inserting a disk and then removing it results in the disk's icon remaining on the screen indefinitely. If your use of the machine involves inserting many disks, the Workbench display will begin to look somewhat cluttered.
This will not be a problem during ordinary use of the machine, since it doesn't interfere with operation of the Amiga. Of course, if the problem becomes annoying you can always reboot the machine, and everything will revert to normal.
• AC- Your Original AMIGA™ AMIGA PRODUCT GUIDE For the Amiga
2000... MicroBotics means Amiga-Power!
Whichever Amiga you own-or plan to buy-we have the expansion you need HlardFrame 2000 Super Speed DMA SCSI Interface If your application calls for super-speed uninterrupted access to your harddisk, Hard- Frame 2000 is your answer. This is a high- end, no holds barred SCSI interface that operates at bus speeds. With cable pinouts designed for compatibility with low cost Macintosh hard drives, one HardFrame 2000 can support up to seven devices.
Word-length data transfer, FIFO buffering, true DMA, all mounted on a metal frame suitable for mounting standard SCSI 3.5" drives "hard-card" style (or, if you prefer, cable connected to a bay mounted or external disk). Available March April, Suggested List price S329.
SB2000 Adaptor Card StarBoard2 Portability Large numbers of MicroBotics Star- Board2 owners have moved over to the A2000. To protect their investment in our technology we've made available a simple, low-cost adaptor card that permits the installation of a "de-cased" StarBoard2 inside the Amiga 2000 (in the first 100-pin slot).
When adapted to the 2000, StarBoard2 is still fully functional autoconfiguring memory plus you get access to all the StarBoard2 MultiFunction options- Sticky Disk, Math chip, parity or the new SCSI Module. Available now. Suggested list price is only $ 49.95. 8-UP! FastRAM Maximum Memory in One Slot!
The FastRAM card that every Amiga owner will eventually come to -why limit yourself to the possibility of only two megabytes per slot when 8-UP! Will take you all the way to the top of the autoconfiguration memory space of EIGHT MEGABYTES ! 8- UP! Uses an exclusive MicroBotics- designed memory module, PopSimm, that frees the user to install his own, conventional DIP-style DRAM in standard SIMM sockets on 8-UP!. If you use 256k PopSimms you can install two megabytes on 8-UP!; if you install 1 meg PopSimms, you can install eight megabytes on one card! In either case you can install the
memory chips yourself for maximum flexibility and mininum cost.
8-UP! Will also accept conventional SIMM memory. 8-UP! Is a power efficient, zero wait state, autoconfiguring design. 8-UP! Will be available 2nd quarter of 88. Suggested list prices start at SI99, For the Amiga 500... M501 Memory+Clock Half a Meg at a Great Price!
As we are all coming to realize, a 1- megabyte Amiga (at least) is a necessity not an option. When you add the inboard 512k memory' and dock module to your A500, make it a MicroBotics-brand, plug compatible work-alike. It uses the exact same kind of memory and the exact same dock and battery. And note that just like Commodore and unlike some third-party expansions, we use a long-lived rechargeable Ni-cad battery by Varta- which you'll never have to replace! Set the MicroBotics dock using the same software (on your WorkBench disk) as you use for the Commodore dock. What's the
difference? You get to keep $ 21 compared to the Commodore version, M501 has a suggested list price of only $ 179.

StarBoard2 500 Two Megs and a Choice of Modules Tire premier memory expansion for the At 000 is now available on the A500. In a sleek, redesigned case with an independent power supply strong enough to power Star- Board2 and another AlOOO-style Star- Board2, all the power and flexibility of this great expansion device is available to you.
Up to 2 megabytes of autoconfiguring, zero- wait state FastRAM, MultiFunction or SCSI module capability for either math chip StickyDisk functions or fast SCSI harddisk interfacing. StarBoard2 500 also has a unique LED diagnostic confidence light to indicate the powered up state of your Amiga and your expansion memory. Another A1000 style StarBoard2 can be connected to the expansion bus pass-UP (it exits through the top of the case) for a total of FOUR megabytes of memory and two modules. Suggested list price $ 339 and up.
For the Amiga 1000... StarBoard2 The Expansion Product of Choice The superb memory expansion for the Amiga 1000, still going strong! Up to 2 megabytes of zero-wait state, autoconfiguring FastRAM in a sleek, ail steel Amiga-colored case plus the capability to accept either one of two daughterboard modules: the original MultiFunction Module or the brand new SCSI Module. StarBoard2 is powered by the bus (up to two StarBoard2's can be supported by the A1000) and passes it on. Available now; suggested list price $ 339 and up.
MultiFunction Module High Tech at Low Cost This "daughterboard" installs on any StarBoard2 (all three Amiga models). It features a socket and software to support the Motorola 68881 Math Chip as an I O device (MicroBotics pioneered this approach on the Amiga -now directly supported in the math libraries in the new AmigaDOSl .3). StickyDisk gives you the most "bulletproof rebootable ram disk -its hardware write protection turns the whole device into a solid state, superspeed disk, alternately, parity checking of StarBoard? Memory can be enabled when extra parity RAM is installed. Finally,
the MultiFunction Module carries an easy to use battery-backed clock to set your system time on start-up. Available now; suggested list price $ 90.00. StarDrive Module Speedy, Low-cost SCSI Interface As an alternative to the MultiFunction Module, all models of StarBoard2 can accept this new hard disk interface. StarDrive affords you cost-effective, pseudo-DMA access to Macintosh compatible SCSI drives and other third-party SCSI devices. Fast, easy to install including driver software and disk diagnostics. StarDrive also has a battery backed clock to set your system time on boot-up.
Available now. Suggested list price: $ 129.95 MouseTime The Port Saving Clock The easiest-to-use, most cost effective implementation of a battery-backed mouse port dock for the At 000. MouseTime passes the port through for joysticks or other devices. Complete with WorkBench software.

- AMAZING PROGRAMMING An IFF Reader In Multi-Forth by Warren Block Almost alt Amiga graphics programs create and use IFF- format data files. This is good and bad. It is good because the IFF format is compatible with many different programs, and it is bad because of the added level of complexity it necessitates in those programs.
When you program in C, IFF examples and routines abound, so it really isn't too hard to make your programs IFF-compatible. Unfortunately, most of the secondary Amiga languages don't include IFF routines, which forces you to write your own. Multi-Forth is one of these languages. Creative Solutions has provided almost everything else with the language, except IFF routines.
Since a general-purpose IFF reader module is a tool that can be used many times, it is worth the extra effort to make it fast, small, and robust enough to survive foreseeable errors.
The Multi-Forth IFF module presented here ("GetlFFBlob") has most of these qualities, and also serves as a showcase for some of Multi-Forth's unusual features.
Description An ideal IFF reader should be very simple to use.
GetlFFBlob needs only the address of a zero-terminated filename as a parameter, and does its own memory allocation and initialization. It returns pointers to standard Amiga structures (a BitMap, a BitMapHeader, and a CoIorT- able) which are ready for use by the application programs.
Errors are handled simply: structures that could not be created because of an error are simply returned as a NULL pointer. While this doesn't tell the calling program what went wrong, it suffices for most uses. Should your program need more information, it can attempt to get a DOS lock on the file. If the lock value returned is non-zero, the file exists. If the file exists and there was an error, the Multi- Forth word lOERROR? Will return the error code of the latest AmigaDOS error. When no error has occurred, but GetlFFBlob has returned NULL pointers, it is probably the result of trying to
read a file that isn't IFF in the first place.
This enables GetlFFBlob to read files that are partially obscured by disk read write errors at least those portions of file that occur before the errors are loaded normally.
Most of the words make heavy use of Multi-Forth's local variables, a handy construct. Also, globals are used (another feature provided by Multi-Forth). With local and global variables and structures. Forth has finally been brought up to current sophistication levels in programming languages.
(Those who are typing these programs from the listings should note that local variable definitions shouldn't be broken into two lines; it will make the compiler freak out.)
The complete package consists of three files: ilbm.f (structure and constant definition), iff.f (the iff reader routines themselves), and ifftest.f, a program to test and demonstrate the use of the reader routines. Ifftest checks on the size of the source page of a graphic image, and uses that data to decide what size screen and window to open. The actual image is then blitted into the window. So full-screen IFF pictures and Dpaint brushes or Images "windows" are read equally welt. BltBitMapRastPort is used to blit the IFF BitMap into the window's RastPort, because it takes fewer parameters
than BltBitMap. When the picture is finally displayed, the program uses the Exec Wait function to wait for a CTRL-C, then deallocates everything and exits.
Of special interest in GetlFFBlob is the GetPixelData word.
It checks the compression type used (found in the BitMapHeader structure) and sets the global variable IFFCompVector to the token value of either ReadPfainRow or ReadCompRow accordingly. Later, when ReadLine is called, it EXECUTES the token value contained in IFFCompVector. This eliminates the need to check on the compression type for every line, and helps speed things along.
BitMapHeader structures turn out to be very useful for things other than IFF files. For instance, they make good descriptors of Bobs when using the Gels system.

Look. Ma. I'm programming!
Memory allocation has been carefully checked and verified everything allocated is later freed (although it is up to the calling program to free memory used by the returned structures). This has been simplified by providing "smart" deallocation routines (found in iff.f). When your program is finished with the structures, simply have it pass the pointers to these routines, and they'll take care of the details.
Chip memory is used only when absolutely necessary; public memory is requested for all other needs. It makes no difference on a 512K Amiga, but it is immediately obvious on machines with expansion memory. With extra RAM becoming more and more common, all programs will have to be written this way, so you might as well do it correctly in the first place and avoid the hassle of later modifications.
Be sure to call GetlFFBlob with a zero-terminated string for the filename. The address is used directly in calls to AmigaDOS, and these calls won't work correctly with normal Forth strings.
Problems, Quirks, And Details GetlFFBlob isn't perfect. (Of course, the ideal program could be written and debugged in fifteen seconds, would require no memory, and run instantly.) First off, it is memory-hungry. For speed, it loads the entire file into RAM (Fast RAM, if available) and decodes it from there.
For typical pictures, this is a 30-40K chunk of memory. This RAM is freed after decoding is completed, but if the memory situation is tight, a crash could result from the attempt to allocate it in the first place.
Besides the file buffer, memory is also allocated for a BitMap structure and its associated bitplanes, a 32-entry ColorTable (even though the actual color data may have less than 32 entries), and a BitMapHeader. Although they arc currently unimplemented, there are provisions for adding new types of IFF hunks like CCRTs, CRNGs, and CAMGs.
These will take even more memory. The small size of Forth programs helps offset the reader's appetite for memory somewhat.
If this is unacceptable for your application, the RAM pseudo-file, used by GetlFFBlob, would make it relatively simple to convert back to reading straight from disk. It wilt probably also result in a drop in speed. (The original disk- based version of the program took 22 seconds to load a picture that the current version loads in three seconds.)
Routines to write IFF files have not been implemented because I have no need for them yet. Another flaw: the routines presented here are only capable of reading graphics files. In the real world, an IFF file can be much more complex than expected (e.g. sampled sounds, songs, text, or other complex constructions). All these things could also be combined in a single file.
Conclusion Although GetlFFBlob may be somewhat crude, the fact that it quickly loads ordinary Amiga graphics files has made it a very useful addition to my Forth toolbox.

The program described in this article is a revised version of a program (by the same name and author) which received very limited distribution as a "shareware" program. I doubt you have come across it, but if you have, please consider the older version "freeware."
If you use AmigaBASIC from a Command Line Interface
(CLI) , you must know the frustration of trying to remember the
names of the programs you previously saved on disk.
At least Workbench users have all those icons to remind them! Sure, you have the 'TILES" command, but is that really sufficient? It does the job, but there has got to be a better way!
"Basic Directory Service Program" is designed to provide you with the information you need, and the ability to LOAD, RUN, display, and delete selected files. To do this, the program invokes the CLI command LIST, the output of which is directed to the RAM: disk, and then read back by BDSP, sorted, and displayed in alphabetical sequence for the user's review and selection. The only caveat is that BDSP must be invoked from a copy of AmigaBASIC which has been started from a CLI. If it is run from Workbench, your Amiga will "hang," requiring you to re-boot. (This is because CLI commands producing
output must have a CLI window to direct it to.)
When you do run BDSP, the screen will blank for a couple of seconds, then the working screen will appear instantly!
When you see it, you will realize that BDSP is "gadget" driven (as opposed to "menu driven"). This means every option available to you (and there are quite a few) is selected by "clicking" a gadget.
BDSP Available Options DFO:, DFI:, DF2:, RAM:, and DHO:, are some of the more obvious gadgets used to specify various devices. Click on a valid (for your system) device gadget, and its root directory will be read, sorted, and displayed. The resulting list may be scrolled up and down by clicking in the scroll bar to the right of the display. (Clicking in the arrowheads will move the list up or down one line at a time.) Move the mouse pointer over the list, and the file directory names are highlighted. Click on a directory name to read and display that directory path. If you click on a file name
you will have "selected" that particular file. The current path is always displayed below the file list. Should you want to go back one level in the current path, just click in the "Previous" gadget. The current directory and file counts are continually displayed in the upper left and right comers of the screen.
Top and Bottom allow you to move the display to the top or bottom of the current list of files and directories.
Array Size allows you to specify the size of the internal array which will be used to hold the information from the current directory. The default of 100 should be adequate for most disks, but if you have lots of small programs and or a hard disk, you may find a higher number more appropriate.
(Just remember, you will need additional memory to accommodate the larger array, and will probably need to modify the CLEAR ,30000 statement at the beginning of the program to specify a higher number.)
ShowFile allows you to display the current "selected" file.
The display is continuous and wraps around as necessary.
When "ShowFile" is selected, a new window opens with a scrolling display, "Cancel", and "Stop Go" gadgets. Clicking in the "Cancel" gadget terminates the display and returns you to the main screen, while clicking in the "Stop Go" gadget will (as the name implies) stop or continue the display. If the file selected is binary, not only will the results be unreadable, but the two gadgets will probably also disappear from view! However, they can still be used, and may be selected simply by clicking in the correct space.
(continued) The remaining gadgets appear across the bottom of the screen in the following order: Quit terminates BDSP and returns control to AmigaBASIC.
Load loads the selected program, making it ready for editing.
Run will load and run the currently selected program.
Previous causes the parent of the current directory to be read and displayed. Note that while you may advance as many levels as you desire, you may only go back the previous 10 levels.
Clear simply de-selects a currently selected file.
Delete erases the currently selected file after a confirmation request. Remember, if a file has an associated .info file (its icon), that file must also be deleted.
Entering BDSP and Setting Things Up Type in BDSP as shown in the accompanying BDSP listing, remembering to save a copy every once in a while.
As you type, notice that three system libraries are used: graphics.library, dos.library, and diskfont.library. This means you must make sure the three associated .bmap files are also available at execution time. The first two are stored in the BasicDemos drawer on the EXTRAS disk which you received with your Amiga.
So, if you don't already have it, you must create the third .bmap file (diskfont.bmap). To do this, just type in Listing 2, save it, and run. It will add a diskfont.bmap file to the BasicDemos drawer on your working AmigaBASIC disk. If you choose this approach, you will also need to modify the CHD1R ":BMAPS" statement to CHDIR ":BasicDemos".
Many users have collected all .bmap files and placed them in a separate drawer named BMAPS. If you have not already done so, you should seriously consider it, because many AmigaBASIC programs use the various system libraries. Full sets should be available from any source of Public Domain software, including Amicus disk 8.
Running BDSP Once you have entered BDSP and saved it, you are ready to run it. You may use any accepted method of executing an AmigaBASIC program EXCEPT executing it from a copy of AmigaBASIC which has been started from the Workbench. 1 suspect that a popular method will be telling AmigaBASIC to execute BDSP automatically, when it gets started. This is done very simply with the CLI command: "run AmigaBASIC BDSP". (The "run" is optional, and only used if you are multi-tasking AmigaBASIC with other programs.)
Programming Notes When you run this program you will note the text displays are not typical of AmigaBASIC. You will further note they are all controlled by a number of sub-programs. These subprograms are all self-contained, may be used in any program, and are fully described in my article "More Basic Text" which appeared in AC V3.2. Specifically, please note the use of the JAM1 mode which allows all of the more interesting effects in the BDSP display.
If you think you may want to use these sub-programs in your own programs, it might be best to enter them first, save them with the ",A" option, then MERGE them into BDSP later.
Please remember that BDSP is a valuable tool in itself, but even if you don't use the CLI (and don't expect to), it may still reveal useful programming techniques which may be advantageous in your own programs. Check it out!

performance-related design decision, it was decided that
Intuition would render (draw) borders and gadgets in the same
layer of the screen as the window'. Because this meant that
ill-considered drawing within the window could trash the
border, the GimmeZeroZero window was provided. In
GimmeZeroZero, borders and gadgets arc rendered into another
larger layer, linked to and underneath the window layer.
A M A Z I N G PROGRAMMING Don't Give Me ZeroZero or, Clip Your Own by Mark Cashman Unfortunately, this type of window has a terrible performance penalty. Users of AmigaBASIC (which uses at least two GimmeZeroZero windows) are probably familiar with the extremely slow updates to newly uncovered window For instance, imagine a line described by two endpoints.
One endpoint is inside the window, the other outside. A complex procedure must be used to clip the line to the inside edge of the window border. Polylines (lines linked end-to-end and going in many directions) are even more difficult to deal with, since they require multiple applications of the line clipping procedure.
Fortunately, the Amiga Graphics Library and Layers Library provide facilities called clipping regions, which allow you to do your own clipping without the overhead of a GimmeZeroZero window or application-dependent clipping routines scattered all over the program.
Clipping regions] rectangles and damage One On-Screen Layer areas. Not only does the GimmeZeroZero window have a slow refresh rate, it also refreshes the other windows at a snail's pace.
One alternative is user software clipping, arranging your program so you just don't draw past the borders of the window'. However, there are many situations where it wouldn't be practical to control drawing to this extent.
Clipping Rect & Damage Intuition uses clipping regions to update newly uncovered portions of simple refresh windows. The regions cause the system to ignore drawing instructions outside of the boundaries of one or more clipping rectangles. (Clustered together, these clipping rectangles form a clipping region.)
When linked to the window Layer structure, clipping regions allow the damage list for a simple refresh window (a window where obscured areas must be redrawn by the (continued) Refreshing an obscured window area The libraries Intuition, Layers, and Graphics are opened.
The window is opened.
The region is created, initially containing no clipping rectangles.
The clipping rectangle is created and added to the region.
The region is used to replace the damage list.
Drawing is performed, enclosed in the BeginRefresh and EndRefresh calls, which bring the fake damage list into play.
The original damage list is replaced.
The region is disposed of.
The window is closed.
Memory is released and the libraries are closed.
Damage Before & After application) to keep track of the covered areas of a window.
When the window is being refreshed by the application program, the only areas where drawing actually occurs are those which have just been revealed. Thus, even though the application may issue drawing operations on sections of the window outside the clipping region, those operations are not performed. This allows extremely fast window updates, because drawing operations that are not performed have only a minimal cost the cost of checking whether or not a pixel is within the clipping region.
The smart refresh window uses a similar strategy for updates. However, the source of the updates is not the application program, but the Layers Library routines. The routines divert drawing operations from obscured sections of a window to an off-screen backup area. When an area of the window is revealed, the system detects it and copies the appropriate portion of the off-screen area into the on-screen portion of the window using a damage list for clipping.
The program below replaces the system-defined damage list with a user-defined damage list (a clipping region which clips everything past the inside edge of the window border).
The strategy used works well, with no modification, on simple and smart refresh windows.
The program uses the smart refresh window type. You will see that with the smart refresh window, the clipping region affects the on-screen portion of the window, and the backup areas. In other words, your drawing is not only clipped into the window, but also backed up into the off-screen areas. When the window is revealed, notice that the entire window contains the drawing, properly clipped by our user- defined damage list.
! Hadn't expected that, but it worked.
The following is an outline of the program: When creating this program, I came across several areas where documented features did not work as I expected.
For instance, the Amiga ROM Kernel Manual states that "DisposeRcgionO is provided to return the [Region] memory to the system when you have finished with it. Not only is the region structure deallocated, but also any rectangles that have been linked into it." Unfortunately, this is not true.
During testing, I found that each time 1 ran the program, an additional 8 bytes were not deallocated. Since this was exactly the size of the Rectangle structure, and I had just one Rectangle in the Region, it had to be the Rectangle which was causing me to lose the 8 bytes. Once I had testclipping.mod when window first is opened Pre-Clipping Drawing linked the Rectangle into my Remember list (which allows me to release all allocated memory at one time), the amount of memory in the system before and after the program run was the same.
In its original form, the program simply opened the window, established and linked the clipping region into the layer, drew the lines, and waited for CloseWindow. Then, I wondered if the technique would work if there were other windows overlapping. So I set up the program to push the window to the background, which guaranteed it would be partly covered.
This caused some strange behavior. The window appeared, was drawn into, and then went to the background. Yet the Amiga Programmer's Handbook (Mortimorc's book from Sybex) states "When the WindowToBack function returns, a specific window will be moved behind all other windows in the same screen..." The Intuition manual is more specific. If I had checked, it would have saved me some trouble in understanding what was happening: 'This routine sends a request to Intuition asking to send the window in back of ail of the other windows on the screen. Note, the Window will not be depth-arranged
immediately, but rather will be arranged the next time Intuition receives an input event, which happens currently at a minimum rate of ten and a maximum of sixty times per second."
This incident showed me the importance of having and referencing multiple sources about any particular feature.
The problem I had was also a failure to take multitasking into account. I assumed an operation would be complete when control returned from a system routine, but in a message-passing operating system, things can be much more Kraau MH

in* mt testclipping.mod after drawing revealed showing smart
refresh works OK Post-Clipping Drawing josely coupled than
that. In this case, the graphics library pcrations were so
fast, Intuition didn't have time to rspond before they took
action. In a situation of testing for nexpected system side
effects, this was a problem. When rogramming an application,
one would not normally plan jr any specific window layering.
Whether or not a indow was concealed during rendering
(drawing) would e of no concern.
(continued) testclipping.mod after clipping region installed and drawing done in refresh mode; Post-Clip Drawing Shown This program also shows the many techniques that must be mastered to write Amiga programs opening and closing libraries and windows, dynAMIGAlly allocating memory and linking it into a Remember list (to be freed cn masse at program termination), and performing a series of structure initializations and system calls. Error and exception handling are difficult, but important especially with the requirement to free allocated resources carefully when a problem occurs.
The program is written in Modula-2, using the TDI library modules. C programmers should know that a Modula-2 program must be read from bottom to top. The bottom section of the program corresponds to the C main() function, and procedures called by the main section are above it. The general rule in Modula-2 is, anything used must be declared earlier in the program.
A few notes on my programming standards: Imported identifiers are always qualified by module name.
Comments indicate special situations, counter-intuitive concepts, or bugs encountered in development.
Procedures are named to define the purpose of their code, reducing the need for comments.
Procedures are sometimes nested (this is not allowed in languages like C or BASIC) to provide additional detail.
Variables are declared in alphabetical order.
All names are long enough (except in the case of those inherited from library modules) to ensure the purpose or content of the named object is clear. TYPE definition identifiers are ended with TYPE to clearly indicate the difference between type identifiers and variables.

Apparently, WindowTo3ack returns before the window is moved, because if these two statements are omitted, then the drawing takes place while the window is still at the front, and the window doesn't move to the back until the drawing is finished.
For testing this program, these statements can give you time enough to move windows around to obscure all or part of this program,'s window. If you do this, you can see for yourself that this clipping technique works even when parts of the window are obscured.
In this version of the program, the window is a smart refresh window. After the drawing has been done, if the window was obscured, and you reveal the obscured parts, you can see that the clipping and drawing affected all portions of the window.
If you add the simple refresh flag to the NewWindow.Flags then only the visible portion of the window is updated with the drawing. The clipping still works fine.

Roomers by The Bandito The Bandito has the inside scoop on one of the most exciting stories to hit Amigadom since the Amiga 1000 debuted the first public showing of the Amiga 3000. The Amiga 3000 was shown at the San Diego Amiga User's Group meeting in April by a group of Commodore International engineers.
They were in San Diego for a special presentation to General Dynamics (or so they told the rapt audience), and found themselves with a few hours to kill before their plane left for Europe.
So they dropped into the SDAUG meeting to show off their baby, the Amiga 3000.
The Amiga 3000 is powered by a 68020, with new Denise and Agnus chips for incredibly high resolution performance. The case was pasted with FCC stickers proclaiming it a prototype model not licensed for sale.
The engineers opened their demo with a new screen asking for the Workbench disk a ray-traced, three- dimensional hand in hundreds of colors, holding a disk and rotating around the screen.
Jaws dropped as the team of European engineers ran the machine through its paces, as they showed off the redesigned 640 x 400 noninterlaced Workbench 2.0 screen and high resolution ray-traced pictures in hundreds of colors. Several animation demos were also shown. Unfortunately, the engineers had to run to catch their plane, so they weren't able to stick around and answer questions.
A reporter from AmigaView magazine was there to cover the whole event in complete detail.
Excited Amiga fans rushed to post the news on bulletin boards, and the rumors spread like wildfire. Debate about the machine's new features raged on UseNet, BIX, and CompuServe.
Consternation reigned at Commodore when the rumors filtered back to them. Who were these guys? Who authorized them to show this machine? What presentation for General Dynamics? There was a great deal of arm-waving, finger-pointing, and handwringing at Westchester, and phone lines hummed with frantic calls from across the Atlantic. No, nobody in Europe knew anything about this.
Who was responsible, then? Dale Luck, ace Amiga specialist and architect of Kickstart 1.3, was called in to find out what happened. Some shrewd investigative work followed, and now the whole story can be told, Remember the Bandito said that this was the April meeting? That's right, it was a hoax, and a beautifully executed one, too.
The masterminds behind this coup were Steve Hartford, president of SDAUG, Mark Randall, president of the LA Amiga User's Group, and Jerry Humphrey. These jokers took a Mac II motherboard, put it in an Amiga 2000 case, and stuck them on a Mac II monitor. They even had some "Amiga 3000" labels typeset and stuck them on the case for authenticity. They used some Mac programs to generate realistic simulations of Amiga software, including the Workbench. Then they did their little show, which the San Diego users bought hook, line, and fishing pole, as did Commodore (for a while). Jerry Humphrey
pretended to be from the nonexistent AmigaView magazine, and he even asked the audience if they'd heard of him (20 people raised their hands).
The hoaxsters started into their act and explained they were there to show the computer to General Dynamics. It looked like the jig was up when someone in the audience said they were from General Dynamics! However, he went on to say that he thought he'd seen the "engineers" at GD that day, and from then on, the audience was convinced. Well, it certainly was fun, though the Bandito doesn't think Commodore sees it quite that way. Bravo for a hoax well done.
Let's just hope the real Amiga 3000 comes out soon, so the pranksters won't have to do this again next year.
The Bandito was present at a very special event Max Toy, president of Commodore, spoke at the First Amiga User's Group (FAUG) meeting in April. The Bandito had heard that FAUG was the biggest Amiga user group in the world, but this meeting was amazing even by those standards.
Well over 800 people were in attendance, maybe a thousand. It was standing room only at the Palo Alto Hyatt. Some of the celebrities in the audience included Dan Silva (author of DcluxePaint) and Jay Miner (designer of the Amiga). Esther Appleton from Micro-Systems Software talked about their new word processor Excellence going head-to-head with WordPerfect; Tim Jenison from NewTck introduced (continued) Digi-View 3.0 software with overscan and extra halfbrite support to the admiring crowd; then Max Toy captivated the audience for more than two hours, answering numerous questions.
Max said that things are going great the stock just reached his option price (remember, he came on board just days before the October 19th stock market crash). Sales are good on the C64, MS-DOS, and Amiga lines, and the company has shown a profit for 7 quarters in a row. Things are great in Europe they're even selling Amiga 500's in German grocery stores.
Unfortunately, there was little else in the way of hard information forthcoming. Yes, Cymmodore is working on new machines, but no word of exactly what or exactly when. But the crowd loved it anyway. Afterward, Max left with about 30 FAUG members to go for pizza at Frankie, Johnny, and Luigi's in Mountain View (if you're interested, Max had a combination pizza, which kind of goes along with Commodore's product line, if you think about it). All in all, it was a successful PR event for Commodore.
Wouldn't it be nice if they could do the right thing in PR more often?
Speaking of FAUG, is it true that Commodore magazine is interested in buying FAUG's magazine Roto City News? The Bandito's spies report secret discussions. RCN could be folded into Commodore's new Amiga magazine, if the deal pans out.
Commodore and Microsoft are engaged in some high-level negotiations about Word, Excel, and other hot Microsoft titles being ported to the Amiga. Commodore wants the legitimacy of the Microsoft name on Amiga products. Microsoft is being coy, but admits to some interest after WordPerfect's success on the Amiga.
We could also see Microsoft Unix or even OS 2 on Amigas in the future (heaven forbid!) The Bandito will tell you more just as soon as he pastes together these shredded documents found in a Westchester dumpster, Well, Amiga Live!, following in Digi- View's footsteps, has announced a software upgrade to add overscan "real soon now." However, the Bandito heard that overscan slows down the snail-like frame rate of Live!
Yes, it's true. PhotonPaint's author, Ori Pelli, has been drafted by the Israeli army, and that's not good news for those awaiting PhotonPaint II. It looks like Digi-Paint II and Deluxe PhotoLab will beat PhotonPaint II to market by a few years. Oh well, perhaps Ori will have enough time to squash a few of the larger arthropods that lurk in the crevices of PhotonPaint before he heads off to the West Bank. By the way, it looks like the other contenders in the HAM Paint Wars won't arrive till the summertime. Deluxe PhotoLab increased its price to SI 39, while Digi- Paint II has had more features
added (final price will be "well under S100").
What happened to DeluxePaint in all of this? We may never see DeluxePaint III, the Bandito hears, because Deluxe PhotoLab is confusing the issue at EA.

While on the West Coast for the FAUG meeting, the Bandito stopped in at the 13th West Coast Computer Faire. Sad to tell, there wasn't much Amiga action. A couple of dealers, a stray user group, and a nifty deal on some Amiga external 3.5” drives (how does S159 grab you?). The Bandito saw more Amiga images on an Atari ST than on an Amiga (they've been busy converting Digi-View pictures over at Antic). The show has really slipped from the "good old days" when Jobs and Woz introduced their little Apple II, and similar technical innovations were common. This year, they even had a booth selling
What's next? People selling car stereos out of the back of their pickup truck?
Well, there was one bright spot for Amiga fans. Jan Lewis (computer industry pundit) conducted a well- attended seminar on Desktop Video.
Over 500 video nerds watched some tapes presented by Dave Barrett of Aegis, Arthur Abrahams demonstrating Amiga Live!, and Tracy McSheery showing a tape of some painstakingly constructed VideoScape animation.
Broderbund showed a brief demo of Fantavision for the Amiga, a totally redone version of their Apple II animation software. The Bandito thinks that Fantavision (which should be out by the time you read this) will drive a nail into DeluxeVideo's coffin.
“NEW” PRINTED 3.5" SHUTTERS Permanent Identification of your Company, Information, or Products.
How about full 32-color animation with sound? The interface looks complicated, but then so is DeluxeV- ideo. (A DeluxeVideo II is supposedly in the works, but don't look for it this decade.) The highlight of the seminar was the appearance of the Video Toaster, presented by Tim Jenison and Paul Montgomery. The crowd oohed and aahed at the sight of live video manipulated in real time. When is it coming out? Look for it this summer, and they're still saying S799 (though the Bandito thinks $ 999 is more likely).

Of course, HAM pictures can be integrated into a document, but something even better is possible you can attach little animated sequences to a document (imagine Maxine saying hello to you from your letter)! How would you print this out? Possibly by using a series of flip animations on successive pieces of paper. This will certainly be a unique word processor.
Epyx is working on some supersecret hardware projects using old Amiga alumni, like Dave Needle and RJ.
Mica!. They've been remarkably tight- lipped about it, but the Bandito hears from his faithful spies that they’re creating their own interactive VCR system. I-VCR is a hardware add-on to regular VCRs that gives you random access control over a videotape while it's playing. You can choose alternatives on the fly with no discernablc time lag. This magic is accomplished by slowing down the frame rate somewhat (from 30 frames per second to about 22, not enough to really be noticeable) and putting additional info on the tape in the right way. The potential market is huge, with VCRs in at least 60
million homes. This technology would allow for some nifty games, especially role-playing and arcade games. Look for Epyx's unit to allow genlocked graphics over the video image. Imagine being able to play Dragon's Lair or FireFox on your VCR. There's no word yet on release, though there may be a showing at the June CES show.
The Bandito's friends in the Mac universe report that the next generation of Macs will have a two-button mouse. What's next DMA or a blitter chip? Could be they'll think of that in a few years. By the way, some of the Bandito's predictions are coming true sooner than he expected. IBM will be introducing some new PS 2 models soon, and they are rumored to include a 12 Mhz blitter chip to help move those windows faster. Of course, enterprising programmers can find a few other uses for a blitter chip, as we've seen so ably demonstrated on the Amiga. Someday, IBM might even add a sound chip. Wake
up, Commodore! Apple and IBM are breathing down your neck, and they don't want to kiss you, either. It's not enough just to drop a 68020 in an Amiga 2000. We need more colors and higher resolution, at least as options. Time is running out.... ¦AC* The C language was designed to be a universal language that would make programs portable from machine to machine. Originally designed for the UNIX operating system, it is perhaps as close as we will ever get to a universal computer language. Although a number of other languages like BASIC and Pascal are available on many different computers,
none enjoy the degree of portability that C does.
C votes firofK tke, C f ocp by Stephen Kemp, PUNK ID: SKEMP HMMMMUMI An Introduction to C Programming on the Amiga.
C is best classified as a 'low level" programming language, because the instructions manipulate only the smallest units that a machine understands, i.e. bytes, numbers, and addresses. However, when used in association with function libraries, it can become as "high" or as "low" as required. Almost anything, from operating systems to arcade games, can be written in C. Is C hard to learn? Well, that depends on you. If you understand the basic programming concepts of variables, statements, and functions, then you certainly have a head start. Ignorance of the basics won't keep you from
learning C if you have the desire it just might take a little longer. Regardless of your background, you won't learn C overnight, but if you put in the effort you will be well rewarded.
When learning C, it is helpful to have good reference materials. The Bible of C is The C Programming Language by Kernighan and Ritchie; however, other excellent tutoring materials have been written that you may find easier to read and understand. Kernighan and Ritchie's book is great when you want to know specific syntax, but it is not very good for explaining the concepts of writing a program.
No matter which book you buy, don't expect to sit down and read from cover to cover like a novel. The better ones will have lots of examples and lessons, and the best will also have a well organized index for looking things up on the spur of the moment.
Of course you will need a C compiler.
There are two very good choices available for the Amiga: Lattice C Compiler from Lattice, Inc. and Aztec C from Manx Software Systems, Inc. Often, you will hear these referred to as Lattice and Manx. The Manx compiler is used for most of the programming examples that you will see in this column, but this docs not necessarily mean that Manx is the best choice. A number of enhancements have been made to both of these products since 1 made my initial purchase. The best way to decide which to buy is to read reviews and talk to users of both products.
If you are not ready to invest in a C compiler, either because you are not sure whether you will like the language, or because you don't know which compiler is better, visit your local Bulletin Board System. On a BBS you can meet people with varying opinions about the C language and C products. Granted, bulletin boards may not provide all the information you want, but they will let you find out what other programmers think.
Visiting the BBS may cause some doubts too. Almost every programmer has some knowledge of the C language, and most programmers have strong opinions about the capabilities of C even if they have never programmed in the language. The old adage "a little knowledge can be a dangerous thing" is often true because some of these opinions, unfortunately, are negative. This negative attitude is due largely to something called the Baby Duck Syndrome.
We have all heard the story that when a baby duck emerges from its egg, it thinks the first thing it sees is its mother. This is true for many programmers, in relation to programming languages. Although it may not be the first language they learn, many programmers become comfortable with a language and then have no desire to look for anything new. Being comfortable with a language is fine, but some of these people put on their crusading outfits and endlessly accost others about how "their" language is the best and all other languages have terrible faults that can't be overcome.
One thing I have discovered is that there is no absolute best language.
The best programmers are those who constantly seek new knowledge and will give everything (and everyone) the benefit of a doubt. If you meet one of those crusaders, just remember that computers and programming are continuously generating. Programmers who can't or won't evolve with the industry will one day be extinct.
With reference material and compiler in hand, it is time to write our first program (see Listing 1). As with most tutorials, I have started with a "hello world" example because it is quick and easy. Figure 1 is a diagram of the parts of our program discussed in the next few paragraphs.

7. End ol function ] C programs are made up of functions.
All C programs require a function named "main" to designate the entry point where execution of your program begins. Any program could be written entirely in the main function, but you will find this is unwise after your programs grow large and complex. Remember, fewer functions don't necessarily make smaller or better programs, and can hinder future program maintenance.
Least document what each function assumes and what it will do. Although we haven't named any other functions or variables, by using meaningful names you can reduce the number of comments you have to write in future programs.
Our main function is declared on line
4. As stated before, this is where our program begins. If our
function was expecting parameters, they would be listed
between the parenthesis following the name. Since we expect
no parameters, the name is followed by an empty set of
The open brace on line 5 indicates the beginning of our function. The open brace is needed to distinguish the definition of passed parameters from our function's code. Line 7 is a closing brace and indicates where our function ends. When the end of a function is reached, program control is returned to where this function was called. All C programs are finished The first three lines are comments and have no effect on our program.
Comments are text occuring between the start " *" and the end "* " comment markers. Commenting is a good habit to form. Many programmers, including myself, fail to comment programs enough. Often a function is written that either makes certain assumptions or is extremely complex. In the future, if changes or bug fixes are required and we can't remember those assumptions, we will have to figure them out all over again.
A well-documented program can help prevent this problem. It is not necessary to comment on every line (some may argue), but you should at Nothing but the best.

(There are ways to end a program before the end of main is
reached, but let's save that for future discussion.)
Line 6 is a call to a function that is defined in our C library named "printf". Unlike many languages, C doesn't have built-in functions that handle input, output or object manipulation. (Objects are things like character strings, arrays and structures.)
This enhances the portability of the language but means that functions have to be written to do these things.
Fortunately, C compilers come with a "standard" library of functions that handle input, output, and object manipulation. The standard library that comes with one compiler, however, may not be exactly the same as one accompanying another compiler.
You can expect many of the functions to be similar. "Printf" is one of these standard functions. It will output the (continued) ATTENTION!

Source string contained in quotes to the screen. Over time, you will see that "printf" is probably one of the most powerful functions in your C library.
Perhaps a future article will cover the usefulness of the "printf" function and all its derivatives.
Notice that line 6 is terminated with a semicolon. The semicolon is used to separate individual statements and declarations. If you fail to include a semicolon after each statement or declaration (a very common mistake), an error message will be printed when you compile your program.
The n contained in our message is the representation for the newline character. After our line is printed, the screen pointer (where subsequent lines would be printed) is set to the next line. Compilers understand the character indicates the beginning of an escape sequence. The character following the tells the compiler which character to substitute into the ONLY $ 4095 w source s14995 string. Most compilers support a number of escape sequences because it is a convenient way of indicating characters that usuaily don't have text characters to represent them. For more on escape sequences,
see Figure 2.
Figure 2 Normally, compilers will support all of the following escape sequences: n Newline (Linefeed) r Carriage Reium it Tab b Backspace V Formleed 0 Null Usually, any character can be represented by a 3-digit octal number following the character. Additionally, most compiters will assume that the characfer following the character is to be left alone if it is not one of ihe compiler's delined sequences and not an octal number. Look at Ihesa examples: This siring has a ft in if This siring has This string has a * in IT This string has This string has a 32 in f This string
has This string has a bn in if This siring has Output Save your program with the name HELLO.C. Usually the ".C" extension is assumed on C source files.
Now that our program is ready, it is time to compile it. (As mentioned at the start, I am using the Manx C compiler and linker. If you are using something else you may have to refer to your documentation for the proper syntax to compile and link your program.) At the CLI prompt type: CC hello.c This invokes the program that compiles your C source code into an object format. Object files are not executable.
The linker is the program that actually makes the executable file. 1 won't try to explain exactly how a linker works because it is not important here. The brief explanation is that a linker is required to resolve external references, define addresses and search the C library. To link our program type: LN hello.o -Lc.lib "LN" is the name of our linker; "hello.o" is the name of the object file (usually an extension of ".o" is assumed); "-L" is a linker directive that names the library we want to use.
In this case, the library is named "c.lib" (the ".lib" is usually assumed by the linker). The linker also assumes you want the program named according to the first object file. Since we have only one module, the executable program will be named HELLO.
Assuming that all has gone well, you can now run your program that was written in C. At the CLI type; hello You should be rewarded with a "hello world." Congratulations on your first successful C adventure.
Now that you have made your first program, go back and modify it to print something different. Don't be afraid to venture out on your own; after all, you can learn a lot by experimenting. -AC* An AmigaForum Conference with Jim Mackraz, the “Stepfather Of Intuition" .
A conference with Jim Mackraz and Dale Luck was held on AmigaForum CO channel 2 on March 16, 1988. The following is a heavily edited transcript of that conference.
RR: Welcome to a very special formal conference, featuring Jim Mackraz, who needs no further introduction (and I know you'd rather read his words anyway). And lurking in the background but hampered by a scheduling conflict is Dale Luck. Jim, would you like to make an opening comment?
JM: This is Jim Mackraz, "stepfather of Intuition," and currently under contract to produce VI.4 with some other Los Gatos survivors. And with some West Chester REAL survivors.
RR: Let's open the floor for questions.
Paul B, go ahead please.
Paul B: Jim, can you tell us what extra features we will see in VI.4. Will it also be a Kickstart upgrade?
JM: V1.4 will be a Kickstart upgrade, plus a Workbench disk. We plan several significant evolutionary changes. One of my favorites is support for hardware scrolling of screens. The FFS will also be in ROM, for use on floppies. It's basically a standard fix enhance release, plus support for some unannounced hardware changes (hehehe).
RR: Keith, you were next, go ahead.
Keith: Thanks. First Jim, thanks for stopping by. You just mentioned "hardware scrolling of the screens"; would that be some kind of replacement for "ScroIlRasterO" ?
JM: Not really. ScrollRaster is a blitter operation; it moves bits. This would be system support for the hardware capability to scroll the displayed portion of a large bitmap by changing a couple of pointers. There are some low-level hard parts, and some user- interface questions, like menus.
Keith: OK, then I guess I have another question: using "ScroIlRasterO" on a multi-bitplaned screen without double- buffering, the display causes a certain bit of "jumping." Do you know if there will be an improvement on it?
JM: Dale says, "Probably not."
RR: Dale, is this related to software or hardware? I.e., will running a 68020 improve the "shearing" which occurs when scrolling, or is it tied to the blitter?
JM: Dale says, "It is the blitter doing it, a 68020 won't help."
RR: OK. Dave Weinbach, you're next.
(Dave Weinbach) I have run into a problem about which I have heard nothing. That is that extreme overscan and the 2090 don't get along at all (R W errors). Any plans to address this with software? Like reducing bitplanes on the fly? (Problem seen with Videotitler and Ppage w more rows.)
RR: This problem was discussed in an earlier conference here with Dave Haynie.
M:This has been addressed. It will see the light of day with the A2090A controller's driver in ROM. A fix in the disk-based driver is also done, but I don't know how when it will be available.
Dave Weinbach: The fix in software is for the 2090A? And what of those of us with plain old 2090s?
JM: As I said, there is a fix in the disk-based driver, too. 1 just don't know when how it will become available.
RR: Jay Craswell, go ahead please.
Jay Craswell: Will you support more than one monitor?
JM: Probably not more than one monitor at a time, with current hardware.
RR: Don Lawrence, go ahead please.
Don Lawrence: OK, thanks. Two questions: 1: I've heard rumors of a 512K Kickstart. I love the idea, but being a 1000 owner. I'm just wondering if this is possible on my machine.
2: I've noticed that recently Commodore has been seeming to "de-empha- size" the Amiga in Amigaf?); i.e. taking the left Amiga key and making it a Commodore key, eliminating the Checkmark ... any comments on that?
JM: The 512K rumor is one of my favorites, as a systems programmer. I don't have any comment on that, apart from mentioning that the A1000 user base is the subject of some VERY protective instincts by the software (continued) team, on both coasts. As for deemphasis, I don't see it. They put the A key back, and Los Gatos never liked the checkmark. They're just trying to do some marketing kinds of stuff.
Nothing malicious, I'm sure. They know where their future lies, 1 believe.
RR: Thomas Hoiaday, go ahead please.
Tom Hoiaday: Amiga stereo makes it possible to think about sound "position." If I want to have instruments spread across the listening area, however, I must do complex mathematical wave manipulations. Any hope of an audio blitter to let me have a marching band move about the room, in real time, via mouse control?
JM: Uh, I don't know exactly what that would take. Good luck!
RR: Mike DeVonish, go ahead please.
Mike DeVonish: We have all "heard" of new or upgraded chips for AMY coming soon; my question is, are things like more bitplanes and color registers in the upgrade path? Or is this too difficult and more like "32-bit" versions of the chip set?
JM: OH BOY! I've been waiting to use this disclaimer file ... We are not at liberty to discuss any unannounced engineering projects which may or may not be underway at Commodore Business Machines, Inc., or any other client. We hope you understand our position in this regard.
Let me say that the problem with DMA bandwidth is well-appreciated in engineering. That is to say, they're all working on it, but I have nothing to report.
Mike DeVonish: Thanks anyway, by the way I LOVE the checkmark!
RR: Vic Wagner, go ahead.
Vic Wagner jMe tadigm: There has been a bit of discussion here on CIS about needing more standards. Are there areas in which you perceive a need for standards?
JM: Indeed. Commodore has signed a license for Commodities Exchange, my input handler standard. It needs some more work of course, and I don't have any insight into the distribution plans.
But it is pretty important. I also think that the IPC business is very important. There is lots of activity on USENET these days (LOTS and LOTS).
Oh yes, IPC stands for JnterProcess- Communication. I personally feel that anything that comes out should not be ignorant of the AREXX work Bill Hawes has done (although I think a non-REXX server should be possible).
RR: Ariel, go ahead please.
Ariel: Jim, I'd like to ask a bit about Intuition. What shape did you think it was in when you took it over? How do you feel you've improved it since then? And where do you see it changing in the future?
JM: Is this a trick question? Weil, Intuition VI.1 (I came in on the middle of VI.1: before the bug fixes) was sort of rushed, in fact it was a BIG miracle that it was as far along [as it wash My key contribution was to make it re-entrant, and working out the bugs that you don't find until you get a lot of fanatics banging away on something. My other main thrust has been to try to make it more possible to do things that weren't thought of when it was first designed, like render into your own requesters, use a different state model for your input, or not have a title bar drawn just to get
screen dragging. I strongly hope to make much more progress on "extensibility" by the applications.
RR: Jim, do you see the intensity of software development increasing, decreasing, or staying the same as compared to, say, a year ago?
JM: Well, it is a LOT more active in Los Gatos this year. Wtiere there were just two software engineers after the shut-down (Dale and Bart), there are four now, with a fifth coming on line.
We are very active. I think it has something to do with Commodore not being broke at the moment, plus needed support for new devices, like the hi-res A2024 grayscale monitor.
RR: Glenn, go ahead.
Glenn: I know that Amiga sales have been very good and was wondering if you had any numbers for total 500 and 2000 sales to date?
JM: I have no great information, nor can I get anyone to discount the claim that they sold 500,000 world-wide by Jan. 1, 1988.
RR: Miles Kurland, go ahead.
Miles Kurland: Are there any things you would like to see Amiga developers doing that they aren't? Or any system features you feel are underexploited (like the clipboard)?
JM: Well, I can't believe there is not a structured drawing program a la MacDraw, although I'm glad since I want to write one. I think the clipboard has to come along, and we'll try to help it along at the DevCon with some examples, etc. I am working on ways that people can get at the display hardware more directly, to use the REAL magic in this machine, without screwing Intuition, and I think there is a lot of potential in that, such as moving overlays for the "tracing" operation of a draw program. Oops, there goes one of my ideas.
Miles Kurland: Thanks. I'm one of those who wants that graphics stuff!
RR: Don Lawrence, go ahead please.
Don Lawrence: Thanks. A couple of short ones (Which I'm sure you've heard ,,,): When will 1.4 be released?
What would it take to make you call something "10"? And Dale: How about selling checkmark stickers to 500 2000 owners?)
JM: I have a nice answer all ready for part one. We also don't like the checkmark. Do you mean the bouncing ball?
Don Lawrence: No, the checkmark!
JM: it is my hope to get rich selling a little ball sticker for the side windows of cars, like that little apple job. If you want checkmarks, there is a whole catalogue of junk, 1 like the socks and the "members only" jacket. 1 just don't like the checkmark.
Don Lawrence: What about 1.4 2.0?
JM: Oops, here's the answer ... We are not at liberty to discuss any unannounced engineering projects which may or may not be underway at Commodore Business Machines, Inc., or any other client. We hope you understand our position in this regard.
The V1.4 release will incorporate major evolutionary changes in both the Workbench and Kickstart system software. We cannot offer a schedule for this project, but we do not expect to release it before the latter portion of this calendar year.
Don Lawrence: Thanks.
RR: Jim, care to address the "2.0" question? What would it take to make the leap to "2.0" in your eyes?
JM: We're saving the designator 2.0 for a non-compatible release. Then, of course, all bets are off. Especially the bet on us getting our contracts renewed. (Grin) I don't think anyone in CBM management has a taste for an incompatible release. 1 DO hope we get a chance to make a "revolutionary" release, not just these "evolutionary" ones. I have a list of things I'd like to see, all big projects.
Don Lawrence: Great answer Thanks!
RR: Go ahead, Keith.
Keith: Thanks. Dale, I guess this one's for you. It has been rumored that you have put together the only existing "portable" Amiga (!). Is this a reasonable thing (hardware-wise) to produce?
( I _want_ one!)
JM: HA!!! DALE JUST LEFT FOR THE AIRPORT. HA HA!... Can I say a little more: the Amiga is video based, and not real conducive to LCD technology. It won't be a "natural" phenomenon to make a portable.
RR: Daryl Thachuk, go ahead.
Daryl Thachuk: OK, what are your opinions about the Amiga in the business world; is it worth my time to develop some business software?
JM: Well, I think CBM leaves a lot of bases open in the business market, so I don't BANK on a big win over Apple or the Clones. I DO think that suitably horizontal packages will get VERY GOOD penetration in the Amiga market still. So, if 1 was going to write a word processor, I think the Amiga is a good platform, compared to Mac Clones (not that I recommend doing a WP), but if you are planning a job costing package for construction, do a PC version. I hope this illustrates my meaning of "horizontal."
RR: Jack, go ahead please.
Jack: I have two questions: Will 1.4 allow for setting the font used by string gadgets? And will there be some sort of locking added to screens so that other tasks (parasite utilities) may open windows without worrying that the user may dose the screen prior to closing the foreign task's window?
JM: Absolutely, you will have much greater control of string gadgets, both for display and input formatting.
Proportional fonts will be supported.
I'm not so excited about parasite windows, especially since I think they can be supported by code NOT in the ROMs. I may do some sanity checking on CloseScreenO if that helps people do magic outside of the ROMs.
RR: Mike DeVonish, go ahead.
Mike DeVonish: Thanks (this time 1 won’t hit a nerve). Jim, you said something about some REAL Amiga stuff, what has not been done with the machine yet?
JM: Well, I think the copper is underused. ! Think the magic you can do with bitplanes is unused. I think there are applications for sprites in business applications, and audio, too. We don't have the resources that Apple docs, and every time I hear about something like a "noisy desktop" 1 get jealous. I also think it could be the best computer for handicapped users, but we haven't got enough people inside to work on it.
RR: John, go ahead please.
John: This may be controversial but here goes, How have rumors about future developments affected current development? Do they help to stimulate new ideas, or do rumor columns in magazines hinder progress in general (and what can be done about the problem)?
RR: Please note I've NOTHING to do with AC's "ROOMERS" column, ok?
JM: I don't think it's a real problem.
Sometimes it's hard to be working on the grunt stuff and hear someone report that we're working on a Display PostScript chip or something wild. Generally, there has been so much of this over the years, that it is only amusing to the principals. The new ideas come often from BIX, Usenet, or CIS. The rumor columns are rarely practical.
RR: Susan Molnar, go ahead.
(continued) Susan Molnar: Hello! Who's idea was it to put the names on the inside of the AMY case? And will Amiga DOS take advantage of the new WORM drives?
JM: You'll note that my name is not inside the case (too late), but if I had to guess, I'd say it was [originally] Apple's idea. I understand that they IC A] have WORMs in house, with plans to hook 'em up. CSA has one at the present time, so it's available.
RR: Daryl Thachuk, go ahead.
Daryl Thachuk: What’s the future of the A1000 and is it true about an A3000?
JM: I can't comment on any A3000 type stuff. We intend to support the A1000 as long as we can, but you'll see that we can't let it hold back ALL progress. Irving Gould was misquoted as saying that the new chips would plug into an A1000. Just let me say that that got some of the WC engineers thinking.
RR: Jim, go ahead please.
]im (Ed): Ok, first everyone 1 talk to says they love the checkmark. Will 1,4 support the proportional controllers?
JM: You can have the checkmark.
Don't you like the bouncing ball? 1 don't know about prop joysticks. We do have the input expert (Kodiak) working with us now.
RR: Don Lawrence, go ahead.
Don Lawrence: Thanks. "We made Amiga, they fudged it up": Who did it? Is there a story here somewhere?
(Checkmarks! Lets have checkmarks!
How about a vote on it?)
JM: I know nothing, I see nothing, I hear nothing, and 1 want my contract renewed.
RR: Linda F., go ahead please Linda F.: Daryl already asked the question about the A3000 so, before I start lusting after the A2000 (not that I love my A1000 any less), are there any plans to upgrade the Sidecar attachment, since I understand that Sidecar cannot access the A1000 serial port.
And (not a question) whoever named this machine has my compliments ... it is the perfect companion and friend.
JM: As Marketing Heavy Rich McIntyre said at AmiExpo, "You turn on the Sidecar, you get a PC done. Does it work? What more do you want?"
I'm glad you like the name. I don't believe there are upgrades planned for the Sidecar.
Linda F.: Then how does one transfer IBM files downloaded from CompuServe on the Amiga side to the IBM Sidecar so that they are accessible to, say, the IBM at the office? Or am 1 asking too much?
JM: You're just asking the wrong puppy. I think PCCopy goes both ways, but I'm sure there is more to it than that. Sorry.
Linda F.: Okay, thanks anyway!
RR: Daryl Thachuk, go ahead.
Daryl Thachuk: Is there a possibility of a PS 2 card for the A2000?
JM: PS 2? Ick. I suppose the possibilities are endless, but the interface is based on an XT AT bus, so it wouldn't be natural, since the PS 2 has the Micro-channel bus. Ick.
RR: Paul B, go ahead please.
Paul B: Can you give us ANY idea if we will see a hypertext-based system for Amy? Also, can you tell me if my current 2090 controller will autoboot with 1.3?
JM: Well, I feel comfortable saying that a "HyperCard" size project isn't the kind of thing going on within CBM these days. Anything in this area will come from a third party, perhaps with a little help from CBM. Your A2090 will not autoboot, since there is no driver in ROM, and you can't read one off the disk until you've got a driver for the disk from somewhere. Maybe someone will hack up a mod, but it probably won't be CBM.
RR: Doug Winger, go ahead.
Doug Winger: First, I vote for the checkmark. My question is simple: when will the Chip RAM be expanded past the 512K mark?
JM: My answer is even simpler: "We are not at liberty to discuss..." But 1 think the new chips are kind of announced. They are drop-ins (with jumper change) for A500's and A2000's, which must be installed by a dealer service outlet. They should appear this calendar year, but I'm not authorized to commit to any dates.
Doug Winger: OK, as long as I know they're in the pipeline, I am happy.
RR: William Hawes, go ahead.
W Hazves: What areas of development are manifestly outside of the manifest destiny of CBM, for those of us planning our next development project?
JM: Manifestly speaking, I'm sure there is no policy, as such. I don't know how to answer your question, although I hope to get the opportunity to discuss it with you. I could only guess they won't do any applications, but they may well jump into bed with a vendor on some particular area, like they seemed to do with Desktop Publishing. 1 understand your concerns; in fact, 1 share them, i'm clearly not the individual to make a statement on this. I think that AREXX targeted a good area, and I don't know what happened business-wise with it. It seems that people make money competing directly
with CBM in some areas, such as disk controller drivers.
RR: And with that it's time to call this one a wrap. Thanks Jim and Dale for an excellent evening, and thank you all for attending.
• AC* SON OF 7 ASSEMBLERS fjor tie Arnica.
By Gerald Hull About a year ago, Amazing Computing published my comparison of seven different native-code assemblers for the Amiga. Almost immediately after that article appeared, new versions of those assemblers were released, and entirely new packages appeared on the horizon. The present article represents another survey of the current state of Amiga assembling.
The Contestants Many of the packages bear familiar names. Metacomco and Lattice have released significantly upgraded versions. The Manx assembler has not changed much, but this time I had access to its linker, and can give a more rounded evaluation as a result.
HiSoft now offers a CLI-bascd version to complement its editor-integrated assembler.
The greatest turnover has been in the realm of public domain assemblers.
Douglas Leavitt, to my knowledge, has not upgraded the program I examined in the first go-round. Wesley Howe brought out a number of revisions to his public domain assembler; however, he has since ceased to support it. Ho has now released a commercial assembler through Inovatronics that we'll be looking at.
An assembler described as "NOT Public Domain" but "freely distributable" has been converted for the Amiga by Charles Gibbs. The complete source code is provided, so if you have any complaints you can simply rewrite it. A new commercial assembler comes from Abacus, famous for their products for the Commodore
64. In effect, it takes the place of Quelo, which no longer
offers a native code Amiga version.
AMA Compatibility As in the first comparison, a major consideration in evaluating these assemblers is their compatibility with the original product for the Amiga.
Produced by Metacomco, it is still sold as the "Amiga Macro Assembler."
However, it is no longer accurate to discuss this in terms of "Metacomco compatibility," as I did in my original article. The new Metacomco assembler is not 100% compatible with the old, though the differences are very minor.
The phrase "Amiga compatibility" would be misleading as well, since all the assemblers we shall look at run perfectly well on the Amiga, despite any idiosyncrasies. I therefore shall use the expression "Amiga Macro Assembler compatibility" for that purpose, abbreviated to "AMA compatibility."
The importance of AMA compatibility is threefold. First, the majority of existing examples of Amiga assembler code reflect the features of that program. Second, the official assembly language include files released by Commodore reflect those same features. Those "includes" provide the definitive expression of the macros, symbols, and structures of the Amiga operating system.
Third, most of the features of the Amiga Macro Assembler were ported directly from the Motorola "Family Resident Structured Assembler," as described in document "M68KMASM DIO." Consequently, AMA compatibility also means you should be able to use much of the code written for non- Amiga 68000 machines more or less directly, assuming their assemblers also reflect the Motorola influence.
As we shall see, particularly with regard to the Abacus assembler, this compatibility is not absolutely crucial.
Programs can be amended and includes can be rewritten. Nonetheless, the degree of AMA compatibility provides a good measure of how much "massaging" you will have to do to existing 68000 assembly code, and how able you will be to assimilate new releases of AmigaDOS.
The Evaluation As in my original comparison, a primary means of evaluating the relative capabilities of the different assemblers is the public domain program STARS10, written by Andrew Tuline of Vancouver, Canada, and released on Amicus disk 12. It consists of some 600 lines of AMA code, and makes extensive use of the Commodore includes. As such, it provides an excellent gauge of AMA compatibility.
The includes represent one aspect of compatibility, but there are a number of AMA features they don't make use (continued) of. Consequently, I charted some of those features to show how the various packages measure up. I also tried to compare the usefulness of the user feedback the assemblers provide, especially in the case of errors, and the degree of control they provide over the object code produced.
In addition, I use STARIO to compare the speed of the various assemblers.
The mere fact that I am able to do this is a measure of how far compatibility has advanced in Amiga assemblers.
When 1 did the first comparison, only two of the packages (other than Metacomco, of course) assembled STARIO without error, and only one produced a runnable program.
This time, with a great deal of diligence and persistence, I have been able to produce an executable result with every one of the assemblers.
This enabled me to use the STARIO program to generate timings that reflect their speed either with or without listings, and with include files either on disk or in RAM.
Finally, many of the packages come with additional features and complementary programs that facilitate or augment assembly language programming. You can find integrated editors, debuggers, high-level interfaces, and assorted programming aids, not to mention linkers and C compilers. It's up to you to decide which features count the most.
Abacus The most idiosyncratic assembler is ASSEMPRO from Abacus, Inc., 5370 52nd Street SE, Grand Rapids, Michigan 49508, (616) 698-0330. The package consists of a disk and 105- page manual, and lists at S99.95. It provides the most or the least, depending on how you measure things.
On one hand, it's the most complete package of assembler utilities. The program not only comes up with an assembler and integrated editor, but also a debugger window and a table that provides information on the 68000 command set. It can generate and debug 68010 code. Furthermore, you can call up both a disassembler and a "rcasscmblcr," that is, a disassembler that produces code ready for reassembly (without line numbers, etc,).
On the other hand, ASSEMPRO does not produce linkable code an XREF or XDEF gets you a "command not implemented" error, for instance.
Despite the claim that "differences from other assemblers are relatively small," it is by far the least AMA compatible of any of the seven assemblers. As a result, it cannot use the Commodore includes. In compensation, Abacus provides its own includes as well as "Offset files" to take the place of AMIGA.LIB, You can save a particular configuration of ASSEMPRO memory allocation, window placements, control settings, and so forth. It is one of only two packages with this useful capability. However, in other respects the user interface seems awkward. For example, the "Open" file requester
doesn't remember the file it last loaded.
ASSEMPRO is the only assembler reviewed that provides no version that runs directly from the CLI, if that's important to you. It's also the slowest of the six commercial assemblers tested. And its memory requirements are enormous. The configuration for the STARIO program, not particularly large by Amiga standards, gobbled up more than 330K. It cannot be recommended for a system with only 512K.
Inovatronics This assembler marks Wesley Howe's graduation from the public domain to the commercial realm of assemblers.
CAPE (Complete Assembler Programming Environment) comes with a disk and a 46-page manual from Inovatronics, Inc., 11311 Stemmons Freeway, Suite 8, Dallas, Texas 75229, (214) 241-
9515. The retail price is $ 89.95. CAPE is another
editor-integrated assembler, giving you the choice between
WordStar and EM ACS command sets, and providing user-
definable function-key macros. It can generate 68010 code
as well, and comes with Arcxx interfacing built-in.
Like Abacus, the user can save a particular system configuration for later use. The package also comes with an assembler called CASM that can be invoked directly from the CLI.
The CAPE "Read" file-into-memory requester doesn't show what's in directories, unless you also happen to have Inovatools 1. This kind of product tie-in I can do without. Also, it automatically names your object code "AsmObjTemp," instead of using the name of the file you loaded, and unlike Abacus or HiSoft it does not let you step through the syntax errors it finds.
Nonetheless, Howe's apprenticeship in the public domain has clearly borne commercial fruit. CAPE and CASM provide many user-selectable optimizations, including the ability to specify PC-relative and basc-register assembly code. They are also among the fastest and most AMA compatible, with a rich set of additional directives and pseudo-ops that can be very useful.
And they excel at object code control.
The early version of the CAPE package I received did not provide any version of the Commodore includes, and had at least one glaring bug: CASM would GURU if you didn't provide a source file name.
However, I have been assured that these problems arc being fixed.
Inovatronics has a generous update policy. Just send in the disk (no cash), and they'll mail you back the latest version.
Gibbs The freely distributable assembler A68K has been released by Charles Gibbs, 21-21555 Dewdney Trunk Road, Maple Ridge, British Columbia, Canada V2X 3G6. He provides five pages of documentation along with complete source code in the distribution package. You can find it, along with a public domain C compiler, on Fred Fish disk 110.
A68K is based on Modula-2 code published in Dr. Dobb's Journal by Brian Anderson in April, May, and June, 1986. Gibbs translated the code for the Amiga Manx C compiler.
Were this a sub-standard assembler, the mere fact that the source is available would silence most complaints, especially if you're a hacker like me. Just rewrite the parts you don't like!
But the program has nothing to be ashamed of, even when compared with commercial products. It is the slowest of the seven, to be sure, but not intolerably so. It is among the more AMA compatible, and automatically performs a number of useful optimizations. A68K provides considerable control over listing, symbol table, and object file output. In short, the Gibbs assembler shows few of the deficiencies that marked the noncommercial programs in my first comparison.
Indeed, A68K is the only one of the current batch of seven to generate Motorola S-records. They are of little use on the Amiga, but handy if you want to download to target 68000's. 1 did find one bug in the parsing of the option that controls the allocation of RAM for the primary and secondary heaps used by the assembler. If I get the chance, I'm going to fix it.
HiSoft The Devpac Amiga package comes from HiSoft, The Old School, Greenfield, Bedford, United Kingdom, MK45 5DE, (0525) 718-181. The 1.2 release contains two disks, a 112-page ring- binder manual, and a Motorola 68000 68010 Pocket Reference Guide for good measure. It seems generally unavailable in the United States, which is unfortunate. It retails for approximately SI 00. If you already have version 1.0, you can upgrade to 1.2 for about $ 35.
You get GENAM, an integrated editor assembler; MONAM, a debugger monitor; and new with the 1,2 release, a CL1 version of the assembler called GENIM. The latter is for people who want to set up a batch file for a whole sequence of assemblies, which can execute automatically while they're raking their lawn. But with HiSoft, you won’t get much raking done.
Without listings, the assembler fairly screams along; it is by far the fastest in this mode.
I took my timings from GENIM.
Although GENAM is very user friendly when it comes to reporting errors it will step you through them one by one GENIM is somewhat the opposite. You cannot stop it with control-C once it's started. Depending on what kind of errors you've made, you can have a frustrating wait before it's through.
GENAM, like CAPE, does not show directory contents when you "Open" a source file for input. And though generally compatible with the Commodore includes, it does generate a "label defined twice" error in some cases.
Finally, it falls short on some other items of AMA compatibility; local labels (1$ ) and octal constants (@7654) are not allowed.
Minor complaints aside, Devpac Amiga is a full-featured and highly professional assembly language package. It gives you a great deal of control over listings and object code, and when not producing listings assembles code at a speed you will find hard to believe.
Lattice The ASM assembler comes with the
4. 0 C package released by Lattice, Inc., 2500 S. Highland
Avenue, Lombard, Illinois 60148, (800) 533-3577. For $ 200, you
get four disks containing it, the C compiler, an enhanced
version of Blink, sundry utilities and examples, plus a
Alas, inside the otherwise impressive manual there is virtually no documentation on ASM. It says "It supports . .
. An extensive set of assembler directives," but aside from brief references to CSECT and XDEF, it says nothing about them. As a result, you have to experiment to find out what the assembler can and cannot do. The only way it generates a listing is via redirection of screen output, which seems a bit of a kludge. It does not seem to provide for symbol table listings.
With respect to AMA compatibility, the 4.0 version of ASM is a gTeat improvement over 3.1. It no longer disallows labels on the same line as MACRO directives, and swallows the Commodore includes with nary a hiccup. It is not AMA compatible in some other respects, however; no local labels (1$ ) or binary constants (%10110) are allowed, for example.
I found a major bug in ASM's object file generation. Anything that causes it to output a number of bytes that isn't a multiple of four for instance, a
DC. B character string precipitates an "object file seek error"
that terminates assembly. 1 have been unable to find out if
this is a known or remedied problem. You can get around it,
however, by appropriately inserting pad bytes.
Manx The Manx C Professional System consists of three disks and some 600 pages of documentation in a standard three-ring binder, at a list price of $ 199 from Manx Software Systems, Inc.,
P. O. Box 55, Shrewsbury, N.J. 07701,
(800) 221-0440. Along with the C compiler, linker, and symbolic
debugger (DB) you get an optimizing 68000 (continued)
68010 68020 68881 AS assembler.
Some 20 pages of the manual concern the assembler.
The 3.6 release of AS does not appear to contain many changes from 3.4. According to the documentation, the only addition is an option to enforce alignment on 4-byte boundaries. In fact, the assembler refuses to accept this option. Also, the new, highly touted Manx SDB source level debugger appears to work only with assembler code generated from C source.
Despite these gripes, the AS assembler is awesome. Overall, it is the fastest of the seven tested, and most versatile as far as the 68xxx chip set is concerned. And it is very AMA compatible. There are, however, some differences in the handling of CODE, DATA, and BSS directives, as well as peculiarities relating to the ability to optimize to PC-relative and base- register code. There are other optimizations as well.
Of assemblers producing linkable code, Manx is the only one that doesn't generate output for the Alink and Blink utilities associated with Lattice and Metacomco. It uses the Manx LN linker instead, which determines whether the code goes to CHIP or FAST memory. It is also the utility that generates the symbol table listing.
Without access to the Manx linker for my first comparison, I shamelessly assumed AS lacked those capabilities.
I'm glad I've had a better opportunity to evaluate it. If one were to judge Amiga C compilers only by the assemblers they provide, Manx would win hands down.
Metacomco We come finally to the latest offspring of the granddaddy of all Amiga assemblers. Version 11.00 of ASSEM comes from Metacomco Pic., 26 Portland Square, Bristol, England, BS2 8RZ, (44-272) 428-781. It consists of a disk and a 67-page manual, and retails for S99.95. As remarked before, this new version is slightly incompatible with the original. It no longer accepts single quotes on files specified in INCLUDE directives. Aside from that, however, it seems completely compatible with the 10.178 version that set the default standard for assembly language programming on the Amiga.
Despite its royal lineage (or perhaps because of it), ASSEM remains the only assembler of the seven that cannot specify code placement in CHIP or FAST RAM. You'll need Commodore's ATOM or D. J. James' FIXHUNK to remedy this. Also, it does not generate 68010 code, nor does it perform any optimizations.
However, Metacomco has remedied the one major complaint against its earlier version: slowness. As the timings show, 11.00 is nearly twice as fast as its pokey predecessor, placing it near the middle of the pack in terms of speed. Professional and proficient in most every respect, ASSEM continues to set a high standard for Amiga assemblers.

TABLE ONE: USER FEEDBACK Table One compares the seven assemblers according to various features relating to user feedback. It evaluates the ability to control the format and information content of listings, and other aspects of user friendliness. For instance, it shows whether or not a fatal error in assembling returns a non-zero value to the operating system. This is useful in terminating batch files, which might otherwise inappropriately continue on.

You should not put too much weight on these results. For instance, the Abacus assembler has different options that can speed it up. On the other hand, the timings don't reflect the 19 seconds it takes to load ASSEMPRO and the source program into memory.
The timings of the other assemblers were taken using the stripped down version of the Commocore includes, since Manx and HiSoft come with them already.
To provide some overall indication of the speed of the assemblers, 1 have concocted a statistic called the "Tenchstar Rating." It is the average of the four timings for each program, divided by the average produced by the original Amiga Macro Assembler.

measures different aspects of Amiga Macro Assembler
compatibility, Of major importance is the ability to accept
the Commodore assembler include files. In addition, a number
of other AMA characteristics are tested. For instance, the
following mathematical expressions should evaluate as shown:
- 1«2! G23*3 = $ fd = 253 128»l£$ ff 2-l = $ lf - 31 In much the
same way, the treatment of character expressions was tested
with these examples: de.l 'abed' ~ $ 61626364
dc. l '"79’ - $ 00273739

From CALIFORNIA ACCESS™ comes the CA-880, a powerful new 3 V2" disk drive for all Amiga® computers.
This highly reliable disk drive formats a 3 VS" double-sided, doubledensity diskette for 880 kilobytes of storage. The CA-880 is fully compatible with the Amiga 1010 disk drive, but offers much more.
The CA-880 is half the size, is considerably quieter, and has an extra long cable.
The CA-880 also has a connector that allows you to attach an additional disk drive.
So why wait until tomorrow for what your computer needs today.
The CA-880 is yours for only S229-95 (suggested retail price).

1. 0 Overview 1988 Commodore-Amiga Developer's Conference
Washington, DC Amiga™ Working Groups Proposal and Discussion
Submitted by Perry Kivolovvitz and Eric Lavitsky This document
shall serve to define the structure which will govern the
formation and operation of Amiga™ Working groups.
The AWC Project is in its formative stages. The distribution of this document at the 1988 Commodore Amiga Developers Conference is intended to spark the interest and the input of the developer community at large. Please read this document and send us your feedback through the means provided.
2. 0 Amiga Working Groups (AWG) This section defines the concept
and goals of the AWG Project.
2. 1 Definition Of An Amiga Working Group An AWG is a formalized
group of developers sharing a strong interest in a specific
area of research and development which may advance the
state-of-the-art in Commodore Amiga software (or, to a lesser
2. 2 Goals Of An Amiga Working Group The AWC project has the
A) To enhance the formal interchange of ideas and technology
within the developer community (and from within Commo
dore-Amiga™ itself) specifically in the development, formali
zation, and publication of software standards (and to lesser
degree hardware standards).
B) To focus the direction of participating developer research in
order to more closely tie future product development to future
directions of the Amiga market place (as globally defined by
C) To supplement and complement basic research and development
being performed by Commodore-Amiga to the extent permitted by
D) To provide materials to be used to produce an annual or
semi-annual Proceedings of Amiga Working Groups. These
proceedings shall be distributed to every certified and com
mercial developer and shall contain the written culmination of
the work performed by each AWG.
23 Ownership Of Work Performed By Amiga Working Groups Any work performed by an AWG shall be the property of the developer community at large with the Amiga Steering Committee acting as the agent of the developer community.
The AWG Steering Committee shall grant free perpetual use licenses to any member of the developer community wishing to have access to or use of any material developed by the AWG project. No member of the developer community may be denied access to or use of any material developed by an AWG.
The purpose of the licensing procedure is twofold, first, to provide an owning entity so that the material produced by the AWG project will not technically be entered into the public domain. Second, to provide for a database of users and interested parties to further facilitate information flow.
2. 4 Connection With Commodore-Amiga™
2. 4.1 Use and Non-Use Of AWG Developed Material It must be
understood by all parties concerned that involvement of
Commodore-Amiga in the AWG Project or in any specific AWG does
not constitute any official endorsement of the work being
performed by that group. Nor does it obligate Commodore-Amiga
to use or not use any of the work performed by any group or
any group member. Commodore- Amiga can, of course, have access
to or use any material developed by the AWG Project
perpetually without any financial liability.
2. 4.2 Involvement Of Commodore-Amiga Staff In The AWG Project
Commodore-Amiga has expressed a commitment to provide two
persons for the AWG Steering Committee. Apart from these two
individuals, Commodore-Amiga staff will participate in
specific working groups as interests and time may dictate.
3. 0 Amiga Working Group Structure
3. 1 AWG Steering Committee (AWGSC)
3. 1.1 AWG Steering Committee Definition And Purpose The AWG
Steering Committee is the top most level of AWG Project
structure. It shall serve several purposes:
A) It shall be the principal investment of Commodore-Amiga
personnel time. Two Commodore-Amiga employees shall be
designated to sit on the AWGSC. Through these individuals
Commodore-Amiga will express its corporate wishes in matters
of AWGSC discussion and also through these individuals
information for individual AWCs requiring Commodore-Amiga
input will be channeled.
B) The AWGSC shall be the sanctioning body for the creation of
new working groups. The formation of working groups must be
controlled for the following reasons:
1. To prevent duplication of effort.
2. In work areas which will require sanctioning by Commo
dore-Amiga: To channel effort into work areas in which
Commodore-Amiga has interest rather than in areas which have
no hope of being adopted by Commodore-Amiga.
3. To facilitate the collection of AWG results by the AWGSC for
the purpose of producing the Proceedings.
4. To ensure that the work of the AWG will be available to all
members of the developer community in a fair and equal manner.
C) The AWGSC shall be the issuing body of free perpetual use
licenses governing access and use of material developed by the
D) The AWCSC shall collect, edit, and publish the results of all
AWGs in an annual or semi-annual Proceedings Of Amiga Working
E) The AWGSC shall prepare and deliver a report to the developer
community at all Developers Conferences summarizing the
achievements of the AWG Project since the previous Developers
F) The AWGSC shall prepare a quarterly newsletter summarizing
the achievements of the AWC Project in the absence of a
Developers Conference during any given quarter. This
newsletter shall be distributed with AmigaMail™.
G) The AWGSC shall be the arbitrating body in the settlement of
any AWG membership disputes which cannot be settled internally
to the working group. Please refer to section 3.2.2 for more
information concerning this point.
3. 1.2 Method For Governing The Steering Committee The AWGSC
shall conduct its own affairs based upon Robert's Rules of
3. 1.3 Steering Committee Structure The AWGSC shall be composed
of 5 members of the developer community and two members
designated by Commodore- Amiga. By internal election one
member shall be designated Chairperson and shall conduct
meetings of the AWGSC under the principles of Robert's Rules
Also by internal election the AWGSC shall elect one member to the position of Secretary. The AWGSC Secretary shall prepare minutes of AWGSC meetings in accordance with Robert's Rule Of Order.
3. 1.4 Initial Composition Of The Steering Committee The initial
holders of the development seats on the Steering Committee
shall be by election by the current members of the Steering
Committee. That is, the members of the Steering Committee
shall elect the newer members until all five developer seats
have been filled.
3. 1.5 Term Of Office And Election Method Developer scats on the
AWGSC shall come up for election after a one year term. The
nomination and election process shall be conducted through
AmigaMail. No more than one person from any one company can
serve on the AWGSC at the same time.
3. 1.6 By-Laws Of The Steering Committee The initial AWGSC shall
be obliged to prepare a set of by-laws which will fully define
issues pertaining to Steering Committee membership and
3. 1.7 Meetings Of The Steering Committee Formal meetings of the
AWGSC shall be held four times per year or more often if
required. These meetings can be conducted in person if
possible or on some electronic messaging system supporting
real time group conferencing.
3. 2 The Working Group
3. 2.1 Definition And Purpose As previously stated, the Amiga
working group is a formal collection of members of the
developer community sharing a common interest in a subject
area as well as having the desire and commitment to invest
time and effort in advancing the state-of-the-art in that
3. 2.2 Membership In The Working Groups Memberships in an AWG is
open to any member of the developer community as defined by
the Certified and Commercial developer list maintained by
Commodore-Amiga. For reasons of practicality the individual
working group shall be free to specify its operating size
though it must be noted that this operating size cannot be
used to prevent an interested party from joining the working
We must expect individual developers to join only those working groups which they are confident that they can and will be able to contribute. Purely for reasons of practicality the members of a working group shall be free to drop from its membership those persons deemed not to be contributing members.
In the event of membership disputes which cannot be settled from within the working group itself, the AWGSC shall act as the arbitrating body.
3. 2.3 Working Group Structure In the absence of any less formal
method, the members of the working group shall elect a
Chairperson. The Chair shall act as a liaison between the
working group and the AWGSC for the purpose of conveying
information to and from the working group and Commodore-Amiga
(if no Commodore-Amiga employee chooses to fulfill this role
directly). The Chair will oversee the work of the group and
facilitate the collection of the groups results for
publication in the Proceedings. The Chair shall also
facilitate meetings of the group by whatever means are
Apart from a mandated Chairperson, the structure and running of the individual working group is left completely to the membership of the group with the expectation that the members of the group are committed to the ideas of the AWG Project (information interchange and technology development).
3. 2.4 Duration Of Membership There will be no formal limitation
on membership in any AWG. Members may retire from the group at
whatever time they choose.
3. 2.5 Meetings Of The Working Groups As with the Steering
Committee, the working groups shall try to meet in person as
often as possible on the occasion of such events as trade
shows and conferences. The Steering Committee shall
coordinate the reservation of space and time at such events.
However, it is expected that a substantial portion of the work of any group shall be exchanged among the group's members via an electronic messaging system.
For the time being, the messaging system of choice shall be the Byte Information Exchange (BIX) where many developers as well as Commodore-Amiga are either already members or in fact already run their own conferences.
Companies already having conferences of their own on BIX may host closed topics as the means of communications among group members.
3. 2.6 Obligations Of The Working Groups Each working group shall
be required to prepare a summary and review of the group's
work to be submitted to the AWGSC for publication in the Amiga
Working Group Proceedings or other publication. Each group
will also be required to submit interim status reports to the
AWGSC for the purpose of gauging group process not so much by
the AWGSC but by the working group itself, Apart from the
above obligations each working group is left substantially
alone with regards to operations with the restriction that no
developer may be excluded or favored over another.
4. 0 Forming New Working Groups For the AWG Project to be a
success it must by its very nature encourage the formation of
new and diverse working groups.
For the results of a working group to be included in the Proceedings and enjoy other benefits of the AWG Project, the group must seek sanctioning by the AWGSC. Keep in mind that it is the job of the AWGSC to encourage the formation of new groups and not to hinder such activity.
Sanctioning by the AWGSC is an essential part of maintaining the overall organization of the AWG Project. Sanctioning will also serve several other aims: First, it will prevent the duplication of work areas between working groups. Duplication of effort cannot serve the developer communities' best interests.
Second, should the desired work area require the involvement of Commodore-Amiga (in the form of incorporation of the results of the working group's labors into the standard "supported" Amiga environment) the AWGSC will solicit Commodore-Amiga's input right at the start before any work has been invested. Should Commodorc-Amiga find that the work area conflicts with other work either planned or in progress the AWGSC will convey this information to the members of the prospective working group for their reasses- ment.
Lastly, the sanctioning process will allow the resources of the AWGSC to be brought to the aid of the group wishing to form a new working group. These resources include the publication of the new working group to attract interest and membership.
5. 0 Initial Working Groups Substantial discussion on the
subjects of IFF standards for animation and desktop publishing
are in progress currently through less formal means. The
initial working groups could be formed around these subjects
to bring a more formal footing to this research as well as
benefit these already ongoing efforts by providing a broader
venue for the work.
Other areas currently being discussed through informal means include: User Interfaces, 1PC, Serial Device Extensibility and other topics. These subjects are also ripe for the formation of formal Amiga Working Groups.
If you are currently involved with any ongoing informal research, it is incumbent upon you to write us at the address given at the end of this document. Your participation in this project is particularly crucial in that you are already comfortable with the concept of working with a dispersed group and you've already demonstrated your interest in seeing some quality results come of your labors.
6. 0 Current Status The Amiga Working Group Project has been
discussed informally for the past four months within
Commodore-Amiga and within the developer community. This
document is the result of these discussions. The fact that you
are holding this paper in your hands right now attests to the
determination of the developer community to join together for
the advancement of the common good.
We have been granted a tentative commitment of resources to publish and distribute the Amiga Working Group Proceedings.
Given our intention of producing a substantial volume of documents for the Proceedings, the tentative grant of resources to accomplish such a feat is a major step forward.
Also, we have been granted the tentative and cautious commitment of Commodore-Amiga to work with us to see if we can't get this project off the ground. If we can, then everyone will benefit. Given the general mumbling for an opportunity like this, if we don't capitalize upon this chance, we as a community will have sent a clear signal that we intend to stay small and isolated rather than become the progressive marketplace we can be.
7. 0 We Need Your Support And Comments Please put your thoughts
to paper (and send the resulting sheets to the address given
below). Specifically, we would like to know what you think of
the AWG Project concept. Will you participate and in what way?
What groups would you like to see formed? Would you help form
them? And finally will you support us in concept?
Please send your views to: CATS - Working Group Survey Commodore Business Machines 1200 Wilson Drive West Chester, Pa. 19380 Note: CATS has been kind enough to allow itself to be used as a collection point for your views. This does not imply any additional support or endorsement of the AWG Project except those which have been mentioned previously in this document.
8. 0 Where Do We Go From Here The nucleus of the AWCSC (the
persons responsible for the creation of this document)
together with interested parties from Commodore-Amiga and the
developer community will collect your views as sent to the
above address. Your input will be designated in a future
edition of AmigaMail. The AWGSC will at the same time attempt
to fill the remaining (four) developer seats (please indicate
your serious desire to fill one of these seats in your input
It is our goal that at least several working groups can be in place and actually produce results for publication by the time of the 1989 Developers Conference.

1 commend the designers on the extent and completeness of the ACOM language. It is full-featured, with over two hundred commands and real language constructs. However, note that the development environment is a bit shabby. There is only a minimal text editor and a trace function for assistance. I suspect any serious programmer would use his or her own favorite editor for both the Reporting module and program development.
