Magellan: The AMIGA Gets Smart 

by Steve Gillmor 

The worlds of artificial intelligence comes to tlie 

AMIGA in the form of A.I. system software. 

In this competitive world 
there is only one winner. 

The results are in and Hurricane has won. According to 
the August AmigaWorld: "Currently, the Hurricane board is 
the best way to increase the performance of your Amiga." 

Now Ronin has designed a whole family of Hurricane 
products that will make your Amiga 1000 or 2000 run up 
to 20 times faster. You'll save hours on ray tracing, desktop 
video, animation, and other math intensive applications. 

The Hurricane family is fully modular, so you can start 
for as little as $600 and upgrade in stages. Start racing with 
the 68020. You can then add a 68881 . Later move up to 
our 68030 and maybe the 68882. Add up to 4 megabytes 
of 32-bit memory and your Amiga will sprint faster than a 
VAX minicomputer. 

Why waste time and money on less performance. Run 
on in to your favorite dealer and get a Hurricane, or call us 
for more information. But whatever you do, don't be left 
at the starting line while everyone else passes you by.

This edition of the Amazing Computing 
letters is entirely concerned with 
'Roomers". We felt the overwhelming 
response by our readers made this a 
necessity. The letters belotugive a truthful 
proportion to the pro and con reaction of 
our readership. Along tvith the overall 
support for the column, there have been 
two negative responses (the most eloquent 
response has been reproduced in this 

We welcome your comments and 
suggestions. We hope to find a suitable 
end to this matter which unll maintain 
the integrity of our "Roomers" column 
tvhile allowing a level of fair response for 
the inditnduals mentioned in each issue. 

Since responditig to each letter separately 
would be awkward, we have taken a 
longer view. A general response and 
possible solution is the subject of this 
issue's editorial. 

Dear AC: 

After following the "ROOMERS" column 
debates since day one, I've decided to 
put my two cents worth of comments on 
the table. 

I think the column is absolutely 
wonderful and 1 salute the BANDITO for 
his covert investigative skills ( any job 
offers from the CIA or NSA yet ?). 
Roomers provides exciting, insightful, 
speculative, controversial reporting and 
gives your magazine a unique look 
amongst the predominantly boring crop 
of computer tabloids. It also reinforces 
the reader's image of AC as being FOR 
the reader and not being intimidated or 
corrupted by the developers in the 
AMIGA market. I've had quite a few 
enjoyable laughs reading ROOMERS 
rebuttals from overiy sensitive developers 
crying "foul", making excuses, and 
threatening legal action Coooooo- aren't 
you scared?) unless retractions are 
printed and apologies issued. 

From the request you published in the 
last issue (October) for reader comments 
on the ROOMERS column's 
"controversy", I sensed that maybe you 
were thinking of buckling in to the 
commercial pressure and terminating the 
column. Please assure me and the rest of 
the readership that you will not ! I won't 

threaten you with anything foolish like 
subscription cancellation (because the 
rest of the magazine is ver>' good also), 
but I will tell you that if you do shut off 
the BANDITO, my respect for AC will 
drop by several notches. 


Anthony DaSilva Jr. 

Clay, N.Y. 

Dear AC: 

Re the Bandito. My jjersonal observation 
is that, however elaborately rationalized, 
the intent of many manufacturers is to 
deceive. "We subscribers and consumers 
need your help and that of die Bandito. 
When a mistake is made, a simple 
retraaion and correction should suffice. I 
urge you to continue Roomers. 

If anyone is looking for a good Bridge 
program, I recommend Grand Slam 
Bridge. It is IBM compatible so a 
Bridgeboard is necessary. It is available 
from: Baron Bridge Supplies, 131 
Thierman Lane, Louis%'ille, KY 40207, 1- 

I should like to say a good word for 

WordPerfect. They have the best 
customer service I have ever 
encountered for any produa of any kind. 

Hubert C. Minard 

Dear AC: 

As a loyal reader and recent subscriber, 1 
would very much like to have my say as 
to the "Roomers" column. Frankly, I love 
it. I subscribe mainly because of it, and 
would be incredibly disappointed if you 
were to discontinue it. You are one of 
the ver^' few magazines willing to risk 
such a column and 1 hope you will 
continue it. 

The only complaint that I could possibly 
have with your magazine, is that you 
have elected to divide your articles 
across several pages, e.g. please turn to 
page 26, from page 9. 


Lars Benton 

Lagima Hills, CA 


I am writing to you regarding your 
••Roomers" column. I read a great deal of 
criticism about this column and the 
"Bandito". 1 also noticed that the sour 
attitudes were from developers that feel 
that their products have received unfair 

Well, I for one, would like to offer my 
support for the "Roomers" column. As 
you have siated over and over again, this 
particular pian of the magazine is offered 
as ENTERTAINMENT. One of the primary 
reasons (among others) that I purchase 
your publk:adon is to read the Bandito's 
latest gossip. I know that the information 
provided by him/her is not substantiated 
and I believe most, if not all, Amiga- 
Owners/ Amazing-Readers, know this 
also. Even given that many of the rumors 
printed are not supported, the fact 
remains; Tliis is for fun. 

Please do not let a few sour-apples spoil 
the fun for the rest of us. Continue tire 
Bandito's column without any restrictions 
or modifications. Don't give into any 
developer's pressure if you can help it. 

Thanks for the fantastic magazine!

True story; Today I went to the local 
bookstore to check for new Amiga mags 
and was glad to see the new Amazing 
Computing on tlie shelf. The cover 
looked kird of familiar though I thought 
that maybe I had seen this issue before, 
so I turned to the Roomers column by 
the Bandito. I knew that I could tell if 
this was an old issue because I would 
recognize the Bandito's column. The first 
thing I al'ft'ays turn to is Roomers by the 
Bandito. I actually get excited about 
getting the new issue of AC because I 
eagerly look forward to the Roomers 
column. I noticed diat Roomers has 
grown to ;5 pages and I think that's great. 

Why I thiTik Roomers is great: 

-It has a lively, candid writing style with 

a great sense of humor.

Artificial Intelligence 

Expert Systems 


You've heard the words. You probably know a bit about what they mean, too. 
You might associate them with white coats, Russian accents and shiny silver 
robots. What you might not know is that you can explore AI on your Amiga. 

MAGELLANtm by Emerald rntelUgence offers performance and interface features 
UNAVAILABLE on the IBM-PC*, PS/2* or Apple MacintosK*. It was designed, developed and 
tested on the AMIGA for the AMIGA. 

MAGELLAN turns your AMIGA into a powerful knowledge engineering 
workstation. It simplifies some of the complexities of artificial intelligence by 
using the power of the AMIGA. It is advanced enough to be simple. 

The AMIGA'S unique capabilities to support inexpensive desktop video, desktop publishing, 
audio/voice synthesis, extended memory, networking and high-resolution graphics make it ideal 
for advanced artificial intelligence development. Advanced to the state of being useful, not a 
graduate-school curiosity. Advanced enough to interface with the real world, and get to work. 
Advanced enough to be useful. 

Use MAGELLAN to capture the expertise of your best salesperson, to help junior sales- 
people "learn the ropes". Build a system to diagnose sick AMIGA'S and prescribe repair pro- 
cedures. Weigh purchasing options in your job or at home. Evaluate performance of the hockey 
team. Drive animations with rules of behavior of the "actors" or objects. Create original com- 
puter art and music. Add real artificial intelligence to games to take them to the edge. 

Best of all, use MAGELLAN to write programs. No BASIC, no "C", no compiler, no 
linking, no waiting. No kidding. With programs written with rules, changes can be made 
interactively — like BASIC — but much, much more etTiciently. People don't think in flow 
charts, or "C" language structures or little curly brackets or parentheses. People think in terms 
of "IF — THEN". As a child your mother would say "If you take that cookie, then I'll ..." 
Rules like this arc how people work, how people decide. This is how computers will be 
programmed by our children. 

Welcome artificial intelligence to the real world^Explore MAGELLAN.

went through that many versions of a 

real name, then gave up." 

-It gives us insight into the computer biz. 
"It also seems as though Aegis's attempt 
to enter the Mac market has collapsed: 
Vultures are circling, and buyout rumors 
are hot and heavy." 

-And of course , new product info. "The 
Bandito's informers in Sacremento report 
that DeluxeVideo II should arrive early 
next year. It will finally support all the 
different graphics modes, and 
substantially improve the power and 
flexibility of presentation." 

Roomers is chock-full of these delightftil 
morsels of information. 

I understand the problem that companies 
have when they are the object of these 
rumors. I suggest that these companies 
give the public credit for understanding 
die difference betv-'een rumors and 
'facts'. I also enjoy hearing their 
responses when they feel that they have 
been wronged by the Bandito. Any 
insight into the Amiga develop>ers' world 
is interesting. If these companies are not 
satisfied with the space for their replies 
in Amazing Mail then you should point 
out the service you do for them hyping 
their products in Hot On The Shelves. 

I hope that you do not put any restraints 
on the Bandito because of their 
pressures. That would be like putting 
David Lenerman on in the morning, like 
making a new formula for Coke, like 
cancelling Star Trek. (You know many of 
the loyal ST fans still don't watch NBC) 

Don't be rash- listen to the complaints 
and give them their space but remember- 
WE LOVE THE BANDITO!!! I hope that 
you get tons of mail in support of him 
(or her). I would like to have the time to 
write to each of the whiners and scold 
them for their lack of understanding. 
Roomers is Roomers and we the readers 
understand that ( even without a 
disclaimer). I mean geez, really! Cut the 
Bandito some slack! 

I believe in putting my money where my 

mouth is so I've enclosed a check for a 
subscription. I am offering this support 
so that you will support the Bandito. 

Very truly yours, 
Eric Donaldson 


I have enjoyed your magazine and 
congratulate you on a job well done. I 
have recently purchased a subscription 
but am dismayed by the letters to the 
Editor in the first issue of my subscrip- 
tion. I am speaking of the letters con- 
cerning the column entitled "Roomers". 

One of the main reasons I chose to read 
and to aibscribe to your magazine was 
the presence of the "Roomers" column. 
There are numerous magazines that 
purport to examine the Amiga but they 
all seem to spend their time hyping the 
various companies that would give me 
the pros and the cons of programs and 
hardware and report these things 

While I will readily state that your article 
has as occasional pro-industry slant, I 
have come to trust your reports and 
reviews more than other magazines. The 
"Roomers" column often tells the 
possible bad side of the industry' and 
tells which products are over-hyped. It 
doesn't matter whether these rumors are 
true, the important thing is that you had 
the courage to print them C and the 
wisdom to make certain everyone knows 
they are just rumors ). 

I can see why the rumors upset the 
executives from the computer industry 
but I believe they are over-reacting. I will 
buy a product because it appears to be 
what 1 want. I could not care iess what 
the management of that company does 
or does not do in its packaging and 
development of products. The only effect 
the "Roomers" column may have on my 
buying habits is to plant the name of a 
company or product in my mind and 
cause me to give that company or 
product some added consideration 
(usually favorable) when it is time to 
buy. To paraphrase the old saying, it 
doesn't matter what they say as long as 
they spell your name right. 

As an attorney, I am only too aware of 
the weight rumors should be given. I feel 
confident that, thanks to your disclaimer 
at the beginning of each article, your 
other readers also read these rumors as 
entertainment and perhaps fmd them to 
show your magazine's willingness to 
admit that the computer industry is still 
run by human beings. We all do strange 
or unintelligent things and I am glad the 
computer industry is the same. 

In short, please continue to run the 
"Roomers" column and congratulate the 
Bandito or. giving your magazine a high 
grade in tnithfulness by freely fmding 

■With kind regards, I am 

Very truly yours, 

W.T. Geddingsjr. 

Manning, Soudi Carolina 

Dear AC: 

In response to your call to keep involved 
and write comments to your publication, 
I have to cast my vote for the Bandito, 
and the "RDomers" column. 

I have talked my sister into buying an 
Amiga 500, but showed her die 
"Roomers" column wherein a predicted 
new Appk: IIGS plus was/is going to 
seriously tlireaten the future of the 
Amiga. I a. so told her that the 
information in the column was of 
variable significance and accuracy. The 
charm of triis regular feature is well 
written sp<;culation, which is periodically 
proved out. The strength of this 
"unconfirmed and printed for 
entenainrrent value only" material I feel 
lies in its potential for keeping every- 
body in the Amiga community on their 
toes (read honest). Keep the Bandito. 

As for the rest of the magazine, your 
scope is impressive. Keep up the good 

Ward C. Martin

Dear AC, 

I have been a subscriber to AC almost 
since the beginning and have enjoyed 
the magazine ver>' much. I am writing in 
regard to the "Roomers" column debate. 

I, personally, read "Roomers" for 
"kicks" — waiting to see which rumors 
will later b'C proven true or false. I 
understand — before reading a word of 
it — ^that ncne of the statements have 
been confrmed and that much of the 
column simply reflects the Bandito's own 

In its present format, it is imperative that 
the AC disclaimer preface the column, so 
that readej s (particularly first-time 
readers) will not misinterpret the 
information as fact-based reportage.

However, there will always be readers 
who consider ANYTHING thai has 
reached print to be FACT, even with the 
presence of such a disclaimer. 

For that reason, it may be wise to 
eliminate any statements that could 
potentially damage the reputation of an 
individual or company until such 
statements can be proven true. After all, 
the Amiga community should not set out 
to discourage developers and related 
companies from producing new Amiga 
software/products by hurting them 
before they have had a chance to 
demonstrate their intentions. 

By the same token, a publication in your 
position has (or should have) the 
reponsibility to inform its readers of any 
product that is inferior, over-priced, or 
hyped-up and should also notify readers 
of companies who have mistreated or 
deceived the consumer in any way. 

That is where AC must cross the fine line 
between loyalty to its readers versus 
loyalty to its advertisers. Understanding 
fully thai you cannot publish a quality 

magazine without extensive advertising 
revenue, crossing this line certainly puts 
you in an unfortunate position. However, 
I have always felt that a magazine's first 
responsibility is to its readers. After all, 
witliout readers, you don't need 
advertisers anyway, right? 

You mentioned that in trying to confirm 
rumors before printing them, you often 
receive no response or , worse, a denial 
"followed by an explanation which 
restructures the original information to 
be favorable to the company." 

In my experience, refusing to deny or ac 
least acknowledge a rumor is as good as 
saying it is true. As far as a company 
restructuring the information, that, of 
course, would be unacceptable to your 

Perhaps you could borrow a solution 
from another publication (non- 
competing) who found themselves in a 
similar situation. Instead of risking 
offense to their advertisers by printing an 
unconfirmed rumor, they'd print both 
sides of the story. First, they'd list the 

rumor and its source ( not an actual 
name but something like "a leading 
developer said"). Next, the person/ 
company- in-question would be contacted 
and given a chance to make a statement. 
Then, both the rumor and the company's 
statement (or indication of tlieir refusal to 
make a statement) were printed in the 
same issue. This gave the reader a 
chance to judge for himself who was 
telling the truth. It's not hard to read 
between the lines and discover a 
"restructuring of the facts". 

I'd hate to see "Roomers" cut altogether 
because I find it amusing. However, if it 
becomes more trouble than it is worth, 
by all means get rid of it. ...and replace it 
with a column that reports problem 
software/products/companies tliat 
readers should stay clear of!

.or ril sue. 

By Lewis Tilley 

Dear Amazing Computing, 

I demand a retraction! Tliis may develop into a case of libel! Your 
magazine printed an insulting article by one of the Durand-Durand boys 
entitled "The Kideo Tapes" (September issue focusjig on "Teaching with tlie 
Amiga). This letter is to inform you that I, Lew Tilley, am NOT an elf!... 
especially I am not " a jolly, old elf as stated by scmeone calling himself 

You should have known that anyone capable of making a pun like Kideo 
when referring to videos made by children would ^^e capable of any number 
of other insulting crimes of desecration. 

My intemational reputation as a serious writer, artist and lover has been smeared with a brush and a scurrilous name 
which may never be removed. In your position as the editor of the "Original AMIGA Monthly Resource", surely you must be 
aware that anyone who writes regulariy for such distinguished magazines as YOUR AMIGA of London, England and a 
leading Swedish computer weekly; a writer who even now is developing an article on Video for the German Editor, Ulrich 
Brieden of Markt & Technik Amiga, must maintain an image of impartial hostility toward all software reviewed and discussed. 

How can I now maintain tliis attitude 
so ably pioneered by men like Ben 
Dunnington of INFO when I have been 
labeled "jolly?" 

The use of the term "illustrator" may 
be justified since I was, many years ago, 
the winner of a Limited Editions Book Club 
award for my iUustradons to the old 
Thomas Wolfe's "Look Homeward Angel"; 
and I have to my credit many sets of illus- 
trations for various magazines, school texts 
and television and film productions. It is 
the "retired" before the illustrator to which 
I object. 

This Christmas, JUMPDISK is to 
present Charies Dickens' "A Christmas 
Carol" illustrated by Lewis Tilley in a 
special disk edition. Now, is that a "retired 

Humph! Why can't tliese young 
whippersnappers who make tlie kind of 
foreign rock music the Durand boys make 
stick with things they know about? 
Messing around with loud music the way 
diat they do, maybe they just don't hear 

too well. "Emeritus" doesn't mean "retired". I am, I'll admit, an "emeritus professor" from the University of Southern Colorado 
m Pueblo, Colorado. Emeritus really means in its Latin sense "without merit", that is to say, "without reward. ..or, not getdng 
paid anymore." That, alas, is true, but I do get a free office AND secretarial assistance (when available) to continue all the 
more pleasurable activities of a full professor of fme art, except teaching classes, from this exciting new technical university in 
Soudiem Colorado. 

"Old elf - that really did it! Have you ever seen a young elf?.,, of course not. It is this final insuh which makes me seek 
redress. To people who deal every day with eight-year-olds, anyone over the age of thirty must seem "old". If this Durand 
man, who can't even spell his own name correcdy, continues to slander me in such a fashion, I shall be compelled to enter 
direa competition with him in the production of Kiddyos which feature elves who never retire, are aJways young, and are 
never, never jolly. 

Mr. Tilley clearly illustrates the obvious error made to bis character

1<XI% "gospel" and to take the column as 
what it is meant to be - entertainment. 
Most of your readers also have the good 
sense to realize that most of the 
information is based on rumors and 
speculations, but if you read Bandito's 
back columns it is very apparent he has 
been "right on" a very large percentage 
of the time. I hope the recent pressure 
does not succeed in eliminating the 
"ROOMERS" column. His column, like 
your magazine, provides a ' breatli of 
fresh air ' to AMIGA owners who 
quickly tire at the lack of skepticism at 
some other publications. We need 
honesty and objectivity not another 
"house organ'. I have never felt "THE 
BANDITO" was being malicious in any 
of his columns and feel that some of the 
complaints against the column have 
basically been "MUCH ADO ABOUT 
NOTHING!" In summary, let me say- 

Earl Davis 

Dear AC: 

I feel the "Roomers" column should be 
left just the way it is. I personally love 
The Bandito's writing style, and I find the 
column a substitute for all tlie chatter 
that goes on at the trade shows which I 
cannot attend. 

The magazines responsibilities in this 
area are : 1) to state explicidy that the 
column is for unsubstantiated rumors; 
and 2) to only publish material after 
attempts at clarification and /or 
substantiation have failed. According to 
your comments at the end of Amazing 
Mail V3.10, you DO perfomi obligations. 

The developers and publishers are as 

much to biarae for the proliferation of 
false rumors as is the Bandito! If they 
don"t want products announced, or want 
to keep details of their product secret, 
then it is THEIR responsibility to keep 
their people quiet until the proper time. 
The Bandito hears all this stuff from 

Also, they should look to tliis column for 
information on how the Amiga 
community may have an inaccurate 
perception of their produa. When they 
see a rumor listed in the column, instead 
of lamb-basting the Bandito, they should 
be glad someone "caught" the rumor, 
and they can then put it to rest. 

Let's keep the Bandito, and remember 
the first amendment — as long as it's 
handled responsibly.

Dear AC, 

I received your October issue in the mail 
today ( thank you for putting the month 
on them). I wonder if it is coincidence 
diat die issue with tliree letters of 
complaint against tlie Roomers column is 
also one of the funniest Roomers 
columns ever. For instance, a certain 
software package "had more bugs than 
the American embassy in Moscow, was 
as slow as Jack Tramiel reaching to pick 
up the check for lunch...". 

By now you may have guessed that this 
is a letter in favor of Roomers! Roomers, 
however, is my favorite column. I read it 
first, tlien the rest of the magazine. I can 
understand that no one wants to see 
their name or product associated with 
bad publicity-and righdy so. But that is 
no reason to write threatening letters 
along the "my attorney will be 
contacting you" vein. 

Your disclaimer states that it is "printed 
for entertainment only" and it certainly 
entertains me. Keep it up. 


Michael Carpenter 

San Jose, California 

Dear AC, 

A "Tempest in a Teapot" has struck 
Amazing Computing magazine in tlie 
Amazing Mail section. 

It is indeed "Amazing" and amusing to 
fuid that certain people feel libeled by 
rumors in a magazine such as Amazing 
Computing. In my opinion the "rumors" 
column is the "National Inquirer" section 
of the magazine. It is full of half trutlis 
and wishful diinking and is there for die 
entertainment value. I enjoy the column 
and it is the article I read before all 
otliers. But if I based my purchase 
decisions, whether to purchase now or 
wait for the rumored product, on 
information in the column I'd be a fool 
waiting forever for something that may 
never see the light of day. If I'm 
interested in a product I always look for 
legitimate reviews of the produa to base 
my purchase decision on. I never base a 
purchase on something written in an 
amusement column. If a rumor says that 

an upgraded produa will be available 
"soon", I still purchase ttie initial issue of 
the product knowing that reputable 
companies always have an upgrade 
policy which 1 may avail myself of later. 
In ±e meantime I've used the basic 
product and will be ready for the 
upgrade features when and if they arrive 
on die market, 

I hope more peole learn to dispense wiQi 
the "tempest" and enjoy die "tea". By the 
way, when did you say diat die Amiga 
75,000 was due for release? 

Bill Braun

Dear Amazing! folk- 
Keep the disclaimer. 
Keep the Bandito. 
Keep die Roomers department. Please. 

I do not read your fine magazine to see 
what someone in a lawyer suit thinks is 
ok for you to print. Nor do I read it to 
have established manufacturers/ 
deveiojsers tell me to postpone my 
purchases for just a little wliile because 
dieir soon-to-be-released vaporware is 
truly (honest! trust me!) what I've been 
waiting for all my life. 

I read Amazing! for news, for insight, for 
opinion, for all your contributions to die 
Amiga community. And I read it for 
entertainment, gossip and rumors: Tlie 
'flavor' of our industry /community. 

Amazing! is unique. Please keep it that 


Yours Truly, 
CapE.B, Schwartz

Dear AC, 

One of the most appealing points your 
magazine has going is the lack of self- 
proclaimed importance (some blue-suit 
companies call this "polish" or 
"commercialism"). Please excuse those in 
blue suits whose scadiing letters may 
have left bums, they come from a crowd 
that thinks "tongue-in-cheek" means an 
armouncer stumbled while reading from 
a prompter. 

Please let those who never loosen their 
ties know that "Roomers", to tile layman, 
is synonomous with "Rumors". The 
Shorter Oxford defmes rumor as " 
General talk, report, or hearsay, not 

Amazing Computing V3. 12 ©1988 11 

based upon definite knowledge." It also 
lists "Talk or report of a person or thing 
as some way noted or distinguished", but 
that definition is listed as archaic. Maybe 
those who take their products and the 
stories about same seriously , should try 
getting in touch witli "dieir public". I 
asked 22 people who read AC what they 
tliought of the Bandito & if they took 
"Roomers" seriously. With no exception, 
llie Bandito is an ok kind-of guy, and 
anyone who gives credence to a column 
tided Roomers deserves whatever they 
get. One said he gets as much 
entertainment from the Bandito's column 
as from software houses' product 
announcemenLs, and finds one just as 
credible as the other. (For those who 
aren't sure about that, it means a person 
can't put any stock in either.) 

In an industry taken as seriously as 
computers, it's nice to have some humor 
now & again. Leave "Roomers" alone. 


B. Gray 

Sun Valley, CA 

Dear AC, 

I'd like to add my input about the 
■Roomer" column in your magazine. As 
long as the roomer starts outside of the 
column, it should be fair game. I take 
what I read diere with a grain of salt. 
After a user group meeting we find 
ourselves talking about some rumor that 
was in the last AC, and asking "Do you 
diink diat it might be true?" It is a fun 
column , as long as it is understood that 
these bits are indeed rumors. 

Keep up the good work! 

Scott W. Smidi 
Sherman Oaks, CA 

Dear AC, 

I recendy heard that your magazine was 
being forced to drop the roomers 
column, due to legal matters. Having just 
purchased the 3/10 issue of your 
magazine I find info in "Amazing Mail" 
that appears to support the possibility of 
such. Being aware of lag time in 
magazine production and die fact that 
there was no label of "rumor" or e\'en a 
disclaimer given by the individual who 
told me such, I feel there is enough to 
enquire about. 

Being a bit more than a reader of AC ( I 

have a copy of all the issues) even the 
first issue had a "Roomers" column 
(without a disclaimer and mendoned 
Commodore to soon be releasing "Amiga 
LIVE!" to be available before the end of 
February->87?). Now it seems to me diat 
rumors get started by even the best of us 
and the thing to do is check die facts 
(even the world was flat until the facts 
were checked out). AC has been doing a 
great job of giving users a quality 
magazine and to lose tlie "Roomers" 
column would not only be an injustice to 
AC but to the readers as well. 

Rumors are a fact of life and AC does 
justice by putting diem under the 
heading "Roomers" which is more than 
most do who create and pass such non- 
verified information, I hope the 
"Roomers" column stays, besides rumors 
are a pan of the evoludon of the Amiga 
and a bit of reality would be missing 
without diem. What better place to 
mention such things as VaporWare while 
leaving hope for such and perhaps 
measure reader interest?- enquiring 
minds want to know!-

Dear AG 

The Metropolitan Symphony Orchestra of 
Boston acquired an Amiga 2000 this past 
year. I was responsible for the choice; 
and while I would like to tell you that I 
picked the Amiga because I made a 
reasoned and informed selection based 
on our needs, tlie tnidi is that I was 
dazzled by the Hi Tech demos. The real 
reason for my choice was a lust for all 
the fantastic graph and audio capabilities. 

It has turned out diat die very qualities 
which led me to the Amiga, are the 
features which have proved to be the 
most important. The world of the 
Cultural Non-Profit, like tliat of the 
software houses, is a Darwinian Jungle 
where you either outshine, outperform, 
or otherwise distinguish yourself from 
the competition, or you go out of 

Our first software came from Aegis. 
Sonix, VideoTilter, Audio Master, and 
Draw Plus, were the programs on which 
we learned to operate the Amiga. Since 
then, we have added nearly twenty 
additional programs from other 

I like the products from Aegis. I found 
them to be uncomplicated, well 
documented, and easy to use. They do 
useful work, and they do it well. Once 
you have iearned an Aegis program, 
mouse use becomes a joy. The and pull down menus used 
by Aegis are standard. You know where 
to look for "print", "save", "open", "new", 
etc. from program to program; and once 
learned, it applies to other company's 
software as well. 

We have used Draw Phis to design a 
potential concert hall and to visualize 
stage settings. Sonix allowed our 
conductor to hear an unknown score 
before committing himself to a 
performance; and VideoTitler gets lots of 
lise on our sample video cassettes. Audio 
Master op>ens horizons to us as 
musicians and acousticians. In short. 
Aegis has quality products at sensible 
prices, an<l in my opinion. Aegis 
soft?v'are helped to put die Amiga in 
die race as a serious machine. 

I am appalled at the ca\falier statements 
made in your ''Roomers" column in your 
October issue. ''Vultures are circling" and 
the suggestion that they are in a state of 
collapse is irresponsible and destructive 
SOurnalism. If I were a first time buyer, I 
would avciid a company described in tlie 
language used by your magazine. I want 
your readcjrs to know that if my 
experience is any guide. Aegis products 
are a solid value and deserve to be 
bought and used. 

I do not believe that your wishy-washy 
response to Aegis in the November issue 
is sufficient. In the years in which I 
published as a music critic, no editor in 
his right mind would have printed 
anything like the scurrilous language in 
your "roomers" column had I said such 
libelous d:ings about a performance 

As long as there are people like me who 
continue to buy, use, and recommend 
Aegis products, their company is secure. 

Yours truly, 

Arthur Frank Benoit,

From The Managing Editor: 

Putting "ROOMERS" to rest! 

It started innocently enough. I received a 
telephone call from a member of the 
Amiga community who wanted to write a 
monthly column for Amazing Computing. 
They argued there wa,s a need for an 
avenue of "leaks" to die Amiga 
community from Amiga developers. Wliy 
not a column dedicated to viewing the 
inner workings of the Amiga market. In 
order to get the best information from 
sources who would not be judged by 
their association with a kno^Ti 
columnist, a pseudonym was invented. 
"Roomers" was bom. 

"Roomers" has become an institution 
(cursed or otherwise) in the ,\miga 
community. The column has seen several 
authors (each leaving when they could 
no longer maintain the pace of a 
monthly column), yet each individual has 
carried a commitment to providing die 
Amiga community a penetrating look 
Into the movement of this growing 
market. In my opinion, each individual 
worked hard to provide insight and an 
honest reflection on the expansion of our 
favorite computer and the individuals 

The column has always been well 
received by our readership. Readers want 
a hint of the new products or 
improvements on the horizon. From the 
letters we receive, our readers maintain a 
distinction from the factual reporting in 
Amazing Computing and the rumors 
presented by The Bandito. 

However, the column has remained a 
bane to developers and advertisers. 
Through phone calls and individuals 
cornering me at Amiga conventions, 
some Amiga deveIof)ers have let me 
know they are not amused. However, 
few have pointed to factual inaccuracies 
in the articles. Even the most negative 
responses have been followed by an 
explanation of why The Bandito may 
have misunderstood their meaning and 
efforts. Almost all have neglected to 
place their dissension in the form of a 
letter to be presented in this forum. 

One individual challenged me in public 
by stating his company would not 
advertise in Amazing Computing wliile 
we carried "ROOMERS". I mentioned the 
rather obvious fact diat "ROOMERS" was 
only one to tliree pages of a magazine 
which carried between 112 to 128 pages 
each issue. Did he feel he was applying 
a little too much weight to this rather 
small percentage of the magazine? 

No, there was a principle involved. He 
sincerely felt we were committing a 
disservice to the entire Amiga community 
by continuing "ROOMERS". It did not 
matter how much we worked in every 
other effort of our publication, he was 
insistent that we be judged by 
"ROOMERS" alone. He remarked that our 

"Is that all?" 

"That's all I can see." I replied. 

"But that's not bad, in fact its 
complimentary. Why would 
someone tell me that 
"ROOMERS" said we were 

"ROOMERS" column made us the 
"National Enquirer" of Amiga journalism. 
To this day we have not received his 
promised letter to print in Amazing 

Even The Bandito receives an 
occasional "Bad Rap" 

Recendy, I received a call from an 
anxious developer who had been told 
The Bandito had written some bad things 
about his company ki an issue of AC. 
The individual openly admitted he had 
not yet seen the anide and wanted to 
know what was said. 

I read the portion of "ROOMERS" which 
mentioned his organization to him over 
the telephone. When I finished, he said, 

"Is that all?" 

"That's all I can see." I replied. 

"But that's no: bad, in fact its 
complimentary. Why would someone tell 
me that "ROOMERS" said we were 

Why indeed. Is it possible The Bandlto's 
column is now seen by some readers as 
a constant negative, disdaining voice? Are 
the insights in "ROOMERS" being read by 
individuals who have already made up 
their minds as to what the column says, 
and not taking time to read the full lexL' 

Let's be honest, The Bandito rarely puUs 
a punch, but I have seen many positive 
statements and compliments wrinen in 
"ROOMERS". Yet, if a good many people 
are allowing bias to rule their 
interpretation, we will quickly perceive 
everytliing in "ROOMERS" as negative. 

Asking The Right Questions 

There are no easy answers. However, the 
best way to discover the right answer to 
a problem is to ask the right questions. 

To The Readers: 

Do the readers of Amazing Computing 
view The Bandlto's comments as the 
statements of a single individual? Are our 
readers aware that this individual speaks 
on the topics and concerns which affects 
us all from a single lone viewpoint? Do 
our readers balance their intake of 
rumors with a good dose of common 

To The Developerss 

Does the Amiga developser community 
understand the importance of an 
alternative viewpoint? Do diey see the 
need to counter the overpowering 
crescendo of superiatives from 
individuals whose occupation is to 
demonstrate the better points of their 
product, while down playing the 
negatives? Do they understand the sense 
of balance that "ROOMERS" gives AC 
Cout of 112 to 128 pages a month only 
two or three are used by "ROOMERS")?

Are we doing all we can to maintain an

are rumors enough of an explanation to 
the general public for tlieir existence? 
How extensively should we monitor diis 
column? When should we contact

Getting The Right Answers 

While there are no complete answers, as 
a publication dedicated to serving the 
needs of the entire Amiga community, 
we must find a means to keep the 
integrity of the "ROOMERS" column and 
still be as fair as possible to all involved. 

This must be done in such a way as to 
allow The Bandito the freedom to report, 
and individuals the right to be free from 
any unjust persecution. 

For this reason, in the future "ROOMERS" 
will maintain a disclaimer, but we at AC 
wilt reserve the right to periodically 
contact organizations and individuals for 
responses. While leaving the original 
column, these responses will appear 
witliin the "ROOMERS" column as asides 
from the editor following tlieir related 

In this way, the "ROOMERS" column 
remains an open forum. Yet, we will be 
allowed to give a second viewpoint to 
some of the more controversial 
statements made within the column. 

The Developer's ResponsibUity 

This procedure will only work if the 
developers concerned return our calls 
and respond to our questions. We know 
that they will not readily admit to 
producing a top secret product, or an 
inner war between members of their 
firm, but this will give individuals an 
opportunity to respond in the same issue

Hot on the Shelves 

by Michael T. Cabral 

slurping Clones 

Five life force-hogging alien 
clones are determined to turn you into a 
computer. (God forbid!) Helplessly, you 
watch as your limbs and organs turn into 
tiny electronic components. Your 
survival depends solely on your ability to 
find your twins, disintegrate them, and 
gain the vital life fluids you desperately 
need. So the story goes in Captain 
Blood, the latest space-age battle from 
Mindscape, Inc. 

Of course, tracking down your 
despicable partners ■won't be easy. They 
are scattered all over an unfriendly 
galaxy that could take light years to 
cover. Perilous flights put your piloting 
skills to the test, and the terrrains are 
ragged enough to shred your ship into 
cole slaw. When you land, things get 
uglier. The lands you comb are infested 
with unspeakable aliens. Tangling with 
Migrax, Croolis-Ulv and the sinister 
seductress, Torka, makes your dwindling 
life that much more difficult. 

Your fmal enemy is time. An on- 
board clock ticks down the frantic two- 
and-a-half real-time hours you have to 
find some of that crucial life fluid. Snag 
one of the clones and you are awarded 
another two-and-a-half hours of 
desperation and sweat. You also have a 
control panel and a mechanical arm that, 
sadly enough, is your own. With this 
arm, you make your desperation moves. 
And as time slips away, the arm begins 
to shake, a victim of your degeneration. 

Captain Blood also adds some 
firesh twists to tlie graphic adventure 
genre with a unique icon transmitter 
language and a whopping 32,768 pianets

Preferred Preferences 

Slavery to Preferences is a liability 
all Amiga users face. Want to print a file 
or picture? We all know the routine. 
Trudge into Preferences, make all 
necessary, tedious changes, then you can 
finally print. Maybe. If you haven't made 
some minute error that forces you back 
to Preferences for another run around 
the circle, you are alright. Otherwise, get 
ready for the runaround. 

Soft-Link Inc. is out to end 
Preferences frustration with Multi-Prefs, 
a utility that allows you to preset 
multiple Preference settings. You can 
create settings for your specific 
situations, name them, and store them 
for later use. Whenever you need those 
settings tliat would have been such a 
bother to reset, just call up your 
convenient Multi-Prefs premade settings. 

Multi-Prefs also lets you combine 
portions of certain settings with parts of 
other settings. If you need the colors 
from one setting, the printer information 
from another, and the mouse pointer 
from a third, Multi-Prefs is cooperative. 

For complete control of Preferences, you 
can also edit, sort, rename, delete, or 
undelete your settings. 

In addition to the Multi-Prefs 
utility, the Multi-Prefs package includes 
three other goodies. "xMP" is a CLI 
version of Multi-Prefs, allowing you to 
restore full or partial Multi-Prefs settings 
from the CLI. "Up" advances printer 
paper to the top of the next page with 
the click of an icon. "Lace" toggles your 
Workbench screen between interlaced 
and non-interlaced modes.

PostScript Print Perfection 

If one good utility deserves 
anodier, then New Horizons Software 
answers the call. ProScrlpt, a PostScript 
print utility, brings typeset quality 
printing to your Amiga. The program 
translates Pro Write documents to the 


Captain Blood 

Amazing Computing VS. 12 ©1988 15 

PostScript language for output to a laser 
printer or other high-qualit)' print device. 

For the PostScript uninitiated, 
ProScript lets you scale fonts, texts, and 
graphics to any size on your Axniga. 
Since PostScript fonts are defined by 
filled lines and cun'cs, the characters 
escape "jaggies" and the "dotty" look of 
bitmapped fonts. PostScript is also fast 
and device indep>endent. Whedier you 
are printing on a Ltnotronic or a basic 
dot-matrix printer, your PostScript file 
works fine. 

ProScript enhances the PostScript 
capability with other useful, related 
features. For instance, PostScript fonts 
can be automatically substituted for non- 
PostScript fonts, or you can download 
non-PostScript fonts to your printer. In 
the WYSIWYG tradition, PostScript pages 
print precisely as they appear on-screen. 
ProScript also allows you to save the 
PostScript file to disk, in lieu of printing 
immediately. And for ease of transition 
for ProWrite users, ProScript's user 
interface is similar to the ProWrite

Photon Animation 

As Microillusions series of Photon 
products continues to grow, so do the 
demands on the creativity of Amiga 
users. Once upon a time, a stunning still 
drawing or a revealing framegrabbed 
image were strokes of creati\'e genius. 
Now with the Photon Mdeo: Cel 
Animator, you are dared to spring any 
and all of your Amiga images to life! The 
latest addition to the Photon family 
allows you to sequence live action 
animation frames captured by a frame- 
grabber, paint or draw a series of frames, 
or even create stop-motion animation 
with a video camera and digitizing 

Cel Animator frees you to mold 
your animation at all stages. With the 
program's Pencil Test option, you can 
preview crystal clear black-and-white 
video camera scenes and check tlie 
motion on your Amiga screen. From 
there, you can select your playback 
speed per second and set on-screen 
delays. Your scenes loop automatically, 
so you are free to polish your work 
without die nuisance of constantly 
rewinding. Timing is also under your 
control with a simple switch of die 
display time. The Pose Test option lets 
you adjust your timing without 
reshooting. Once you've got the timing 
roughly where you want it, you can add 
breakdown drawings, and re-time your 
delays for pinpoint accuracy. 

Cel Animator also throws off the 
constraints of 
media. Rather 
than forcing 
you to shoot 
and reshoot 
film or video 
scenes in exact 
sequence, the 
program lets 
you shoot each 
image only 
once. As you 
record, each 
frame is tagged 
with a number, 
so you can 
move frames 
change your 

and add 01 delete frames without the 
tedious work of reshooting. With Cel 
Animator, useless backtracking and 
reshooting are not parts of the editing 

Ce! Animator also recognizes that 
your animation is only half complete 
without sound. The program lets you 
digitize and save an audio track with any 
Amiga sound digitizer and dien load it 
into Cel Animator. You can tlien .step 
your audic dii'ough, frame-by-fi'ame in 
real-time with no distonion to see and 
hear preci;;ely how your animation will 
fly. Deciphering sounds and storing 
phonemes and sound effects according 
to frame n'-imber allows you to print out 
an "exposure sheet" and track die bits 
sound in yaur animation frame-by-frame. 

Cel Animator includes many other 
features to open up your animation 
options and make your work easy. The 
program loads images in all 40 Amiga 
graphics formats, and opens and saves 
any IFF files. Your playback choices are 
highlighted by reverse piayback, 
playback with sound, and slo-mo. .4 box

AmiEXPO California '88 

The Amiga Event 

by Stephen Kemp and Stephen Pietrowicz 

From the moment the doors opened to 
the public, AmiEXPO California was a 
sight-and-sound extravaganza. This was 
the fourth AmiEXPO to be held and the 
second for California this year. As with 
each of its predecessors, this show 
proved to be larger and even more 
exciting than the last. 

Even before the show opened, you could 
feel the excitement in the air. We 
arrived at the Westin Bonaventure hotel, 
in Los Angeles, about two o'clock in the 
morning. By the time we finished 
checking into our room, we had already 
seen several exhibitors and organizers 
roaming the lobby and halls, waiting for 
die show to begin. Wlien AmiEXPO 
opened at noon on Friday, the eager 
people waiting in the long lines outside 
the exhibition hall began to pour in 
through the doors. 

The first stop for most people was the 
NewTek booth. They were greeted by 
Laura Longfellow, the "face" that you see 
in many of their demos, including 
"Maxine" Headroom. Demonstrations of 
their main products, Digi-View and 
DigiPaint, were held in the booth, as 
well as, the new NewTek Demo Reel IL 
This "reel" is as impressive (if not more) 
than their first and included a number of 
sequences from popular sci-fi shows like 
"Star "Wars", "Star Trek", and "Aliens". 
NewTek was also discussing tlieir newest 
product, the Video Toaster, which is a 
real time, full color digitizing, video 
effects, genlock system. 

Most Impressive! 

Perhaps the most impressive thing at the 
show (which is saying a lot since almost 
every booth had something impressive) 
was at the ASDG exhibit. Perry 
Kivolowitz, president of ASDG Inc., 
announced that their new color image 
input system, SpectraScan, would begin 
shipping by the end of October. This 

software and hardware package provides 
impressive, state-of-the-art, high 
resolution, full color image input and 
output processing. I know that sounds 
like a mouthful, but it appeared to be 
everything that ASDG claims and 
perhaps more. 

this product seemed to be how easy it is 
to scan an image. Every operation takes 
place on the screen, in real-dmc, on the 
image that you are scanning. A "trial 
scan" can be selected to quickly input a 
black and white image of the original, 
which then allows you to select a 

AmiEXPO California '88 attendees arrive early 

Driving a Sharp JX-450 color scanner, 
SpectraScan is capable of inputting a 
color image up to 11 X 17 inches in size. 
The input resolution is variable from 30 
to 300 dots per inch and will report 24 
bits per pixel of color information. That 
results in a palette of l6 million colors! 
One of the most fascinating things about 

subrange to concentrate on and enlarge. 
The "fine scan" has all the capabilities 
that the package allows and will input a 
full color image of the subject material 
that surpasses anything currently 
available in the Amiga market. 

Now if you are sitting out there with 

The first stop for most people was the NewTek booth 

Amazing Computing V3. 12 ©1988 11 

Perry KwoUnoils, president ofASDG Inc., deinonstraled SpectraScan 

your calculator, you might have figured 
out that a full 11 X 17 inch, 300 DPI, 24 
bit color image would require a 
tremendous amount of memory. Don't 
worry, ASDG has addressed this problem 
by implementing a demand paged virtual 
memory environment. With as Htde as 
two megabytes of FAST memory and a 
"large" hard disk, the image can be 
handled quite easily. They demonstrated 
that scrolling through the image using 
SpectraScan was actually faster than 
some paint programs currently available. 
And there isn't another one available 
which can handle a picture near this 

inexpensive, if you are considering 
entering the professional publishing or 
merchandizing markets then you better 
not overlook this offering from ASDG. 

Another offering from ASDG (which is 
included in the SpectraScan package) is 
the Twin-X general purpose I/O board. 
This is an Amiga 2000 compatible 
expansion card which can host two 
standard IEEE 959 modules or one 
double- wide IEEE 959 module. A 
standard IEEE 488 interface module, 
available from ASDG, can be attached Co 
the Twin-X board which will allow your 

Amiga, to communicate with a 
number of mechanical devices 
including, test equipment, 
plotlers, and medical equipment. 
The Twin-X retails for S329 while 
the IEEE 488 interface module 
cost; $199. 

Moving around the floor, it was 
obvious that many attendees 
spent a lot of time drooling over 
the hardware expansion booths, 
tryir.g to determine who was 
offei"ing the most hard drive or 
memory expansion for the 
mor.ey. Great Valley Products 
(GVP) was one such exliibit. At 
GVI"s booth everyone had the 
opportunity to view hard disk drives and 
controllers available for the Amiga 500 
and 2000, as well as, FAST RAM cards. 
Amiga 500 owners may want to make 
note that GWs Impact A500 hard drive 
system provides an intemal connector for 
installing up to 2 megabytes of additional 
memory. For the 2000 owners, a 
"HardCard" may be just what the doctor 
ordered. GVP offers a hard drive on a 
card, available in 30MB or 45MB sizes. 
The advantiige of the HardCard is that 
the expansion bay is left open, making it 
available for other peripherals. 

"Okay, it handles color input 
and manipulation quickly and 
easily, but how about output?" 
Is this your next question? 
Well, SpectraScan can convert 
its 24 bit per pixel data into a 
standard Amiga HAM image as 
■well as other standard image 
formats. In fact, future releases 
are expected to support 
conversion to popular Apple 
and IBM image foraiats. 
Several "hard copy" images 
were on display in the booth 
and most were printed by the 
H-P Paint Jet printer. This 
hjrther demonstrated the 
power of this package. 

ASDG believes SpectraScan 
may change what the words 
"desktop publishing" means in 
the future. SpectraScan lists at 
$995 for the software and 
hardware interface and the 
Sharp JX-450 scanner lists for 
$6995. Aldiough it is not

Supra Corporation was on hand with a 
full line of Amiga peripherals including 
hard drives, memor>' boards, and 2400 
baud modems. The drive systems are 
full SCSI compatible and available in 
sizes up to 250MB. Memory boards 
containing up to 2MB can also be 
included into the drive systems available 
for the 500. Supra representatives were 
demonstrating just how quickly a series 
of IFF files could be read from the disk, 
achieving an almost "animation" 

Three new boards were shown at 
Interactive Video Systems' exhibit. Tliey 
introduced a new multi-function board 
called the Grand Slam for the Amiga 
2000. Tfiis board includes a SCSI hard 
disk controller, parallel port, serial port, 
and can contain up to 8 megabytes of 
RAM. What more could you wanL' 
Attendees who didn't need all the 
capabilities of the Grand Slam were 
shown IV's new hard disk controller, 
TrumpCard. The TrumpCard is a new 
entry into the low-cost SCSI disk 
controller market, retailing for $189- It 
can support up to 7 drives chained 
together, and has a socket for the new 
1.3 Auto Boot ROM. Interactive Video 
didn't stop there. Those waiting to 
"build" their own boards were 
introduced to Prototyping Tools, a fully 
functional, auto-configurating, bareboard 
for the Amiga 2000. With these three 
offerings Interactive Video can certainly 
say they have something for just about 

Spirit Technology was on hand to 
demonstrate a 2 megabyte memory 
board for the Amiga 500. This is an 
internal expansion board that fits under 
the radiation shield in the ventilation air 
flow. It uses 1 megabit 256k x 4 DRAMs 
and requires no jumpers and no 
soldering for installation. Also 
demonstrated was a ST-506 hard drive 
adaptor for the A500. This adaptor (also 
available for the AlOOO) attaches to the 
expansion bus and provides a slot that 
can hold a standard ST-506 hard drive 
controller (half size card). The ST-506 
interface is compatible with a wide range 
of hard drives found in the IBM and 
compatibles marketplace. 

Memory And Storage Technology (MASD 
was present demonstrating their unique 
hard drive (Tiny Tiger) that interfaces 
through the parallel port. That's right,

the printer port! Ft incorporates 
something they call "Transparent 
Transfer" circuits that allows it to 
distinguish between disk I/O request and 
other parallel port functions. MAST also 
had a few other of their "Matchbox 
Collection" on hand, which included a 
dual floppy disk drive set that is about 
the size of the standard Amiga external 
drive box. 

Want to speed up your A2000? 
Computer Systems Associates was on 
hand to demonstrate several products 
that would do just that. CSA offers 
accelerator boards for the A500, AlCXM, 
and A2000, These boards are designed 
to replace the 68000 with a more capable 
68020 running at I4mhz. This can cut 
the time required by CPU intensive 
programs dramatically. If you have an 
A2000, CSA is offering the DragStrip 
which can pack up to 1 6 megabytes of 
memory and features lightening fast 
screen updates and hard drive accesses. 

For those of us with A5(X)s and AlOOOs, 

who want the A2000 capability without 
giving up our cunent machines, Comp- 
U-Save may have just the ticket. The 

BusExpander, manufactured by Bill's 
Boards, is a motherboard that can be 
attached via cables to the A50O or 
AlOOO's expansion bus. Once placed 
inside an IBM AT style case with a 
power supply, you can then use any of 
the A2(XX) or IBM expansion cards that 
will fit in the A2000, Of course it takes a 
little work and requires more room than 
a 2000 would, but it may be a more cost- 
effective way to upgrade. The 
BusExpander sells for S495 and an AT 
case with power supply should cost less 
than $200. 

Naturally, the exhibitors demonstrating 
genlock capabilities and video titlers 
drew their share of the crowds. The 
video interface technology seems to be 
growing by leaps and bounds due to the 
Amiga, opening doors to a large nimiber 
of potential vertical markets. 

The people at A-Squared Distributions' 
booth were hard at work demonstrating 
their newest hardware for video effects, 
the LIVEI2000. LIVE!2000 rounds out 
their line of LIVE! video frame grabbing 
hardware which has already been 
available for the A500 and AlOOO. The

Elan Design was on hand demonstrating 
their software which relies upon the 
LIVE! hardware. Invision allows the 
Amiga to become a real-time video 
efTects system. With this product you 
can change the image color, mix it with 
an image from your favorite paint 
program, or stop the action. Anyone 
thinking about making their own "film", 
mixing animations with real life, will 
have to give Elan Design a look. 

Several vendors were on hand 
demonstrating the latest hardware 
available for broadcast quality genlock. 
Two such exhibitors were Digital 
Creations, offering SuperGen, and Magni 
Systems with ±ieir 4000 Series. The 
products offered by these companies had 
a number of people mesmerized for long 
periods of time. Both products look 
surprisingly similar on the outside, 
although there were some significant 
differences. Each product comes with its 
own "controller" panel which has two 

slide pots to control the mix of the video 
signal from an external source and the 
Amiga. Adjusting one of the slides from 
one end to the other causes the image 
on tlie screen to switch gradually from 
one source to the other. Magni's 
controller also offered the ability to mask 
out one of the colors from the Amiga 
source allowing the video signal to show 
dnrough from behind. Perhaps the most 
significant difference between the 
products is that SuperGen is compatible 
with all three Amiga Systems, whUe 
Magni Systems' 4000 Series is only 
available for the 2000 and another 
computer called die IBM. 

Most everyone in the Amiga communit>' 
knows what a Boing Ball is, but how 
about the Boing Mouse? What's a Boing 
Mouse? It's an- optical, three button 
mouse for the Amiga that was 
demonstrated at AmiEXPO! Instead of a 
roller in the bottom of the mouse, it has 
a LED and comes with a mirror pad. 
The mirror pad has a grid on it that tells 
the mouse where it is moving. No more 
"click-click-dick" when you roll across 
the table! The Boing Mouse is 
compatible widi the existing Amiga 

mouse port and comes with a 4 foot 
cable. Boing Mouse is slated for release 
on December 7, and will be available 
from: Boing, 1881 EUwell Dr., Milpitas, 

If their interest in Amiga Hardware 
waned, attendees of AmiEXPO had a 
variety of software exhibits to visit, Of 
course some of the most popular booths 
were the bootlis demonstrating grapliics 
and animation software. A number of 
new tides were demonstrated at the 
show or announced for "eminent" 

Antic Publishing, a familiar name in the 
Atari arena, is making a big splash in the 
Amiga marketplace by introducing two 
new software packages and a disk 
collection that users of Sculpt 3D and 
Videoscape 3D might find interesting. 
Zoetrope, autliored by Jim Kent who 
brought the Aegis Animator to the 
Amiga, is Antic's new animation system, 
Zoetrope gives the user the ability to 
create cell animations over any range of 
frames. Jim didn't forget compatibility 
either — Zoetrope accepts the fde 
formats of IFF, 'VideoScape 3D, Aegis 
Titler, Aegis Animator, and LIVE!. Antic 
has also entered the games market by 
introducing the first HAM mode graphics 
game, Pioneer Plague! Pioneer is a 
multi-level, arcade style, strategic action 
game that uses the HAM graphics mode 
and stereo sound. This one may be the 
first of a new generation of video games. 

Not to be left out, B)te by Byte was on 
hand fielding questions and 
demonstrating Sculpt 3D, Animate 3D 
and their latest offering, Sculpt Animate 
4D. Needless to say, there was always a 
crowd at their booth watching with 

MovieSetter is another interesting 
animation product announced by Gold 
Disk. MovieSetter is billed as "the first 
true what you see is what you get 
animation program for the Amiga". Gold 
Disk says that this product includes 
animation techniques that were 
pioneered by Walt Disney studios. It wiU 
allow you to create several minutes of 
"movies" without tremendous memory 
requirement (1 meg is recommended). 
MovieSetter also handles animation 
speeds up to 60 frames per second, and 
supports fijll stereo sound and panning.

A sight and sound extravaganza 

As we stated at the beginning of this 
column, AmiEXPO California '88 was a 
sight and sound extravaganza. Even 
before that first attendee walked through 
the door, the exhibitors with offerings in 
the "sound" area were tuning (or 
turning) up the band. At several points 

during the show, the sound level 
reached that of a rock concert. 
Fortunately, nobody suffered any 
permanent damage and most seemed to 
actually enjoy the competition. 

MicroIUusions had one of the larger 
booths in the hall, exhibiting a variety of 
available titles. Demonstrations of 
Photon Paint were shown on a large 
screen projector so no one had any 
trouble getting a good view. On the 
otlier side of the exliibit, MicroIUusions 
had Music-X, a music software package 
that interfaces with MIDI devices. It was 
apparent that a great amount of effort 
has been put into making the software 
an excellent product. The system 
supports real-time recording, includes a 
number of editing features, and has a

Brown- Wagh Publlshing's booth 
contained packages from most of the 
developers that they market, including 
Zuma Group, PAR Software, and the 
Softwood Company. Brown-Wagh just 
announced a new product they will be 
publishing called MIDI Magic, developed 
by Circum Design. MIDI Magic appears 
to be a promising product for the music 
novice, as well as, the music expert. The 
screens use windows, gadgets, and 
menus, much like other Amiga products 
currently available. If you can't 
remember what to do, just press the 
HELP key and the online help screen will 
be displayed. The program's controls are 
based upon the standard tape deck, with 

play, record, pause, rewind and fast 
forward. Other interesting features 
include the use of a "fuel gauge" for the 
amount of memory left and a metronome 
to count the beats. Beginners wiU 
probably have no difficulty using this 
package to delve into the world of MIDI.

is Pro'Sound Designer. It is a new 
sound sampler that will sample up to 
32kH2 in mono and l6kHz in stereo. 
With the software included in the 
package, it is possible to edit up to four 
sound samples at once. The user 
interface looked very good and seemed 
quite easy to use. Midi-Plus software 
included in the Pro'Sound Designer 
package allows sounds recorded with the 
sampler to be played back through a 
MIDI keyboard, or the Amiga. 
Pro'Sound Designer lists for S159.95. 

Owners of Precision Incorporated 
products can now get technical 
assistance through the Official Superbase 
Information Network (OSIN) on 
American People/Link. According to a 
press release, Precision plans to 
implement a support program for 
developers wishing to develop and 
market their own Superbase applications. 
The OSAD (Official Superbase 
Application Developer) program will 
give developers access to proprietary 
information about Superbase, as well as 
marketing assistance for products 
developed with Superbase. This 
program should be in place after 
November 30.

Aegis astounded a great many attendees 
■with its impressive list of audio and 
visual products including two or their 
newest titles, Lights! Camera! Action!, and 
AudioMaster II. Lights! Camera! Action! 
offers the ability to combine IFF pictures, 
IFF sounds, Aegis Sonix scores, and 
ANLM style animations into a single 
presentation. Aegis thinks this product 
supplies the necessary capabilities to 
develop business and educational 
presentations, as well as, videos for 
product demonstrations. AudioMaster II 
is a full blown digital sampling and 
editing package. It allows you to alter 
and store full stereo sounds into a true 
digital stereo sample. Sampling rates up 
to 44K are supported and if your Amiga 
is equipped with a 68020, AudioMaster II 
will support a rate of 56000 samples per 
second in mono or 52.6K in stereo. Of 
course the samples produced by 
AudioMaster II are usable with Lights! 
Camera! Action!. 

The Business side of the Amiga 

Business and productivity tools are 
proving that the Amiga is, indeed, a 
powerful machine. Anyone who is 
inclined to say the Amiga is just a great 
graphics machine has not seen what is 
available. Numerous vendors had 
exhibits to demonstrate their wares for 
the home and business. 

One of the newest programs to enter the 
productivity world is MAGELLAN, from 
Emerald Intelligence. iVLAGELLAN is a 
software system designed to simplify the 
development of expert systems. Using 
this package, it is possible to capture 
information from human experts, which 
can then be used to help aide "non- 
experts". The system is built around "IF 
- THEN" rules or constructs, the same 
way that a great many "human" decisions 
are made. Using these rules and 
statements like, "If the system won't turn 
on then the electricity must be off, 
MAGELLAN makes it possible to build an 
expert system to help solve computer 
problems. In fact, it would be interesting 
to find out if they have thought about 
designing a teclinical support expert 
system using MAGELLAN. 

Software Visions flew coast-to-coast to let 
visitors to AmiEXPO see their latest 
version of Microfiche FUer. Microfiche 
Filer Plus has all the same capabilities of 
its predecessor and has added a number 
of new features. Now included in the 

product is the ability' to store HAM and 
overscan graphics images, automatic 
number formatting, automatic field 
calculations, and a full AREXX interface. 
The AREXX interface is especially useful 
because it allows the product to 
"communicate" with other AREXX 
compatible products. Using Microfiche 
Filer, it is possible to store thousands of 
records while being able to retrieve or 
sort tliem quickly and easily. The new 
HAM graphics support means tliat it is 
possible to build databases of high 
resolution pictures that could be used by 
"pictorial" based businesses like real 
estate or produa marketing. 

For those requiring modem 
communications, Oxxi Incorporated now 
offers A-Talk lU. Tliis package was 
developed by Felsina Software and 
includes all the standard features that 
everyone expects from communications 
software, plus a few more. It offers 
Specific support for 10 different modems 
and a generic modem for custom 
corifiguraiions. A-Talk is also capable of 
emulating 7 different popular terminal 
types. It supports graphics exporting to 
such programs as Deluxe Paint and Aegis 
Draw. If you don't like to type or can't 
always seem to remember a complicated 
sequence required to log into a bulletin 
board then the script language will help 
you out. A "learn" mode is offered that 
will build the script from recording the 
steps you perform. Once you have a 
script, it is then possible to edit it to 
make specific changes. Finally, A-Talk 
III has also joined those offering AREXX 
support. As an example of how useful 
this feature is suppose you don't have a 
client's number in your phone list in A- 
Taik III. Using the AREXX interface it is 
possible to query a database product 
(like iVticrofiche Filer Plus) to retrieve the 
number and return it to A-Talk III, which 
can then place your call. 

Oxxi also offers several other packages 
for the home and business use. 
MaxiPlan 500 and MaxiPlan Plus are high 
powered spreadsheet programs offering 
traditional Rinctionality while taking full 
advantage of the Amiga's unique 
environment. Nimbus 1, a small 
business accounting package, is offered 
for those who don't need or want overly 
complicated features. Witli Nimbus all 
the accounting functions are running 
concurrently, which means that in the 
middle of ujxlating an account you could 

write a check to someone. It is good to 
see that vendors recognize and use the 
power of a multi-tasking machine like 
the Amiga. 

Micro-Systems Software received a lot of 
attention by demonstrating the usefulness 
of its packages Excellence! and The 
Works! Platinum Edition. Excellence! is a 
WYSIWYG word processor that allows 
graphic images to be placed in the 
document and has a "spell check as you 
type" feature. The Works! is five 
programs integrated into one. Included 
is word processing, telecommunications, 
a database, a spreadsheet, and a 
sideways printing utilirj^ With The 
Works!, Micro-Systems has tried to 
address the most common needs of the 
home or small business user. 

Micro-SysteiTis Software attracted a lot of 
attention to themselves by using an 
"actor" inside the booth. A Madonna 
look-a-like lift-synced several songs, 
drawing people from all pans of the hall. 
Although, it may have been a little 
overdone, it did work. At a get together 
arranged by MSS on Saturday night, 
another person that closely resembled 
Elvira was out on the dance floor 
drawing looks from everyone. 

WordPerfect Corporation was present 
demonstrating tlie power and ease of use 
of its word processor. WordPerfect 
offers a new product called the Library' 
for die Amiga. The WordPerfect Library 
includes a Calendar to help keep track of 
important dates :md appointments; a File 
Manager to help organize and manage a 
personal database; a Calculator so you 
won't have to dig around on your desk 
looking for your real one; a Notebook to 
help maintain lists; and finally a Program 
Editor. This is a powerful text editor 
which has left out those word processing 
features that aren't useful to writing 
programs, while including programming 
features that aren't useful to word 

Prescript is the latest product offered 
from New Horizons Software. This 
softu'are package now makes it possible 
to print their Pro Write word processor 
files on a Postscript printer. If you don't 
have a Postscript compatible printer, 
ProScript can output the document to 
disk and you can send that file to 
someone that does, like a professional 
printing service. Having access to the

Don Hicks Jrom Amazing Computing 
asked all Amiga users to get involved! 

Postscript world means that you will be 
able to produce "near" typeset quality 
documents without the need of a 

Soft-Logik Publishing Corporation has 
gone a step further than most by offering 
a complete desktop publishing product 
called Publishing Partner Professional. 
This package offers the features of a full 
blown word processor as well as many 
of the features required for t>'pesetting, 
including Postscript output. If you don't 
have a Postscript printer, it offers full dot 
matrix support, including color printers. 
The program also includes a number of 
graphics import capabilities and has its 
own art program too, allc^sing you to 
include art inside you documents and 
flow text around it. 

Of course few of the great products 
avaOable on the Amiga are possible 
without program languages. Lattice, Inc. 
has armounced that Lattice C 5.0 should 
be shipping in November. We were 
impressed with the new features and 
improved capabilities of Lattice C. 
Building on the many features that have 
been offered in past versions, 5.0 will be 
the new state-of-the-art C programming 
language for the Amiga. It will come 
with two binders of documentation that 
appears to be well written and 
organized. One of the new additions to 
the produa is a debugger that will allow 
breakpoints to be set in multiple task 
simultaneously. If you have ever tried to 

debug a program that communicates 

with another, you can appreciate this 
feature. Several other programs and 
utilities will be included with the product 
to aide in program development. If you 
are considering purchasing a C language 
or upgrading your existing one then 
check into Lattice. 

Naturally a great many games were on 

display at AmiEXPO. Some we have 
already mentioned but many we have 
not. Games attracted a lot of attention at 
the show, which just goes to prove that 
Amiga users also know how to have a 
good time. 

Haitex Resources stayed busy from 
beginning to end demonstrating their X- 
Specs 3D glasses. These enable the 
wearer to experience a new dimension 
in computer graphics and game software. 
Programs have to be written to support 
the glasses which contain high-speed 
liquid crystal shutters. Opening and 
closing the shutters independendy at 30 
frames per second causes each eye to 
see a slighdy different version of die 
screen. This is similar to the technology 
used to make 3D movies, except they 
use filters to alter what each eye sees. 
Looking at the screen without the glasses 
is much the same as looking at a 3D 
movie without their glasses. 

Another interesting game just out is 
called StellarX from Laser 
Gamesmanship. This game might 
remind you of the old Asteroids arcade 
game, but it is much more than that 
game ever was. There are dozens of 
levels to traverse, more aliens to conquer 
and terrific arcade type action in this 
game. I wish I had a quarter for 
everyone that tried this game at 
AmiEXPO. A unique feature of the game 
is that is has online help, which is 
available by pressing the Help key. 

Microdeal had several interesting titles on 
display at their booth. Their latest game 
is called Tanglewood. Tanglewood is a 
graphics adventure game, but no text 
entry is required. The basic story 
revolves around your search for some 
very important documents. It's not as 
easy as you might think — because you 
are on an alien planet with a harsh 
environment and hostile competitors. 
You have 5 old style "mobiles" at your 
disposal but they each have different 
abilities. To solve the game you will

One title that turned a lot of heads at the 
show was in the Free Spirit booth. 
Hardly anyone could resist stopping (at 
least for an instance) to look at the 
package for Sex Vixens From Space. 
The only thing that we'll tell you about 
this game is the disclaimer that appears 
on the box: "Free Spirit Sofhvare, Inc. 
disclaims any responsibility for alleged 
damages, consequential or 
inconsequential, resulting from 
inappropriate use of this game. This 
includes, but is not limited to, allegations 
of eyestrain, near-sightedness, high 
blood presstire, feeble-mindedness, 
priapism, nymphomania, nervousness, 
insanity (temporary or permanent), 
unwanted hair growth or loss, mental 
incapacitadon, excessive perspiration or 
general physical debilitation." What 
more could we say? 

Starvision International introduced three 
new entertainment games that are to be 
released this year. Mega Finball is an 
arcade style pinball machine game 
boasting hyper sound effects and superb 
graphics. Twin Ranger is another arcade 
style game that can handle 2 players 
while smoothly scrolling horizontally and 
vertically. Snowberry is a game based 
upon a weekly televised program. In 
this game you control Snowberry, a litde 
bear, by making him jump from one ice

There were itmny more exhibitors and 
products at the show than could be 
covered in this article. These we have 
mentioned were just a few of the most 
noticeable at the California AmiEXPO. 
Of course, there's more to "The Amiga 
Event" than products and booths. 
Several keynote addresses were made by 
prominent people from the Amiga 
industry and seminars were held to 
exchange information about program 
development on the Amiga. Joel 
Shusterman, vice president of Marketing 
for Commodore, gave the first keynote 
address. A large audience was on hand 
to hear from the former president and 
founder of the Franklin Computer 
Corporadon. (Franklin made Apple 
compatible equipment). He expressed 
great enthusiasm at the prospjea of being 
able to market the Amiga, calling it "the 
best kept secret in the industry". He 
hopes to turn around the Amiga market, 
and get the word out to the rest of the 

Shusterman said that Commodore will 
begin focusing on the professional video, 
home video, graphic arts, and multi- 
media markets. A videotape aimed at 
the graphic arts market was shown 
during die speech. Mr. Shusterman 
indicated that, in the near future, 
Commodore would be making more 
video tapes aimed at other markets. 

According to Shusterman, within the next 

ninety days, die following products wiU 
be shipping from Commodore: 

o A2620 - The 68020 board. 

o A2286 - The AT bridge board (XT and 

AT compatibility), with 1 MB RAM. 
o Amiga 2000HD - A bundled package 

that includes an Amiga 2000, a 40 

MB/20 ms hard drive, and the 2090A 

hard disk controller, 
o Amiga 2500 - A bundled package 

consisting of the Amiga 20(X)HD and 

the A2620 card. 

Hard disks that are shipped will already 
be formatted and configured, meaning 
that purchasers will be able to use them 
right out of the box Mr. Shusterman 
also stated that there will be an upgrade 
program for owners of tlie 2090 hard 
drive controller to the newer 2090A card. 

Don Hicks, managing editor of Amazing 
Computing gave the second keynote. Mr. 
Hicks talked about a variety of different 
things concerning Amazing Computing 
magazine and the Amiga community. 

Mr. Hicks applauded all the developers 
and Amiga owners who are helping to 
make the Amiga a success. He stated 
that two years ago, there were 186 
developers in the Amazing Computing 
product guide. As of this writing, tlie 
product guide that is currently being 
compiled will have over 600 developers, 
and almost 1200 products for the Amiga. 

Continuing his discussion about the 

magazine and the Amiga, Don suggested 
every Amiga user had a responsibility to 
tell the Amiga developers and vendors 
what they exf)ected and needed in 
Amiga products. He suggested, "If you 
have any comments or suggestions for 
Amazing Computing, or any Amiga 
company, send them a letter! Letters 
receive a tremendous amount of respect. 
Remember, you are the best resource we 
Amiga developers have." 

Don Hicks had the honor of announcing 
the winner of the first Amiga Community 
Service Award. This award was given to 
Perry Kivolowitz, president of ASDG. 
Don spoke of Perry's contributions, not 
only through ASDG, but also throughout 

the /Vmiga community in both hardware 
and software. Perry, who co-authored 
the Amiga Working groups proposal, is 
working to bring developers in the 
Amiga community together to help 
enhance the Amiga. Congratulations 

Fred Fish gave the keynote address on 
the last day of AmiEXPO. A sizeable 
audience gathered that morning to listen 
to tlie famous software "packrat" (as he 
called himself) of freely redistributable 
software. In his address, he explained 
how the library got started and how he 
decides what software will appear on the 
Fred Fish disks. He also addressed what 
the terms "public domain" and "freely 
redistributable" really mean and how 
important such software is to the Amiga. 
Mr. Fish also spoke of what he hopjes tlie 
future of the Amiga will hold and ended 
his talk by fielding questions from the 

Of course Amiga shows are more than 
just products and sp>eeches — tJiey're fun 
too. It's a time and place where Amiga 
users can get together to rub elbows 
with each other and have a good time. 
In faa, they are almost like family 
reunions! The next time AmiEXPO is in 
your part of the country, try to take a 
day and visit. You won't be

The time has finally come to 
announce a long awaited upgrade notice. 
If you have not been living in a vacuum, 
you may have already heard about the 
availability ofWorkbench 1.3. For 
those of you who have not yet received 
the upgrade, here are the details. 

Workbench 1.3 has a suggested 
retail price of $29-95 and comes with 
both Kickstart and Workbench 1.3 disks 
plus documentation. Amiga 2000 and 
500 owners do not, of course, need the 
kickstart disk, as your Kickstart is internal 
to the computer in ROM. This brings up 
a question of the necessity of upgrading 
the Kickstart ROMs. The only feature 
that the new Kickstart ROMs have that is 
not in the original 1.2 Kickstart ROM is a 
hard disk auto-booting feature. If you 
wish to have your Amiga 2000 or 500 
boot direcdy from a hard disk, you will 
have to order a new Kickstart ROM. The 
ROM upgrade has a suggested retail 
price of S45.O0. 

The availability ofWorkbench 1.3 
is expected to be in short supply. The 
upgrades may be purchased at your local 
Amiga dealer, if he has them. One local 
dealership was told when the upgrades 
were ordered, that all dealers would be 
receiving only 40% of the total number 
ordered with the first shipment. The 
remainder of the order would be filled as 
production catches up with demand. 

Two other upgraded products 
have been released by Commodore. The 
A209OA auto-booting (with 1.3 kickstart) 
controller has replaced the A2090 which 
has been discontinued. The pricing 
remains unchanged. The A2052 RAM 
expansion board with 2 MB of RAM has 
been replaced by the A2058 board. The 
latter board has 8 MB of sockets, with 2 
MB chips included. Pricing on this board 
is expeaed to be slightly higher than the 

older board, however, the current price 
was not available as of this writing. 
Also, for current owners of tliis 
hardware, there was no announced 
upgrade path, and none was expected. 

According to a notice posted to 
Peoplelink, the HP PaintJet driver in 
WordPerfect needs a slight modification 
to make the bold function shut off The 
command passed to the printer from the 
8/10/88 version of WordPerfect is 
<27>(s)B. It should be <27>(sOB. The 
posting recommends correcting the 
mistyped character with WordPerfect's 
PrintDef program. 

Early shipments of Gold Disk's 
unique publishing program Comic 
Setter have a problem with the printer 
drivers. If you have recendy purchased a 
Comic Setter and it will not print a comic 
, you can return your disk to the dealer 
for replacement. After shipping several 
hundred of these packages (I was told by 
the folks at Gold Disk that the number of 
copies of the program that were pre-sold 
was tremendous), they found that they 
had accidentally shipped version 1.3 
printer drivers with an incompatible 
version of printer.device. If you have a 
hard disk and have not tried to boot and 
print direcdy from your Comic Setter 
disks, you probably won't have noticed a 
problem. They were very apologetic diat 
this problem occurred, and they 
promised that they were sending 
correaed disks to dealers directly for 
replacement. They also said that if a 
dealer could not help the customer with 
this problem, to contact Gold Disk 
direcdy. According to the representative 
from Gold Disk, dealers were shipped 
enough corrected disks to match the 
number of units originally ordered.

Aegis VideoTltler has a bug that 
involves operation from the WorkBench 
when used from a hard drive. It seems 
that VideoTider only operates properly 
from the CU when it is started from a 
hard drive. This same problem also 
exists with Aegis Draw Plus, as was 
reported in Bug Bytes in volume 3.1. 
Aegis technical support suggests starting 
both programs from the CLI rather than 
the Workbench. 

One suggested workaround for 
those who really want to start their 
software from the Workbench is Xicon 
which is on the Fred Fish disks, and can 
now be found in the C directory of 
Workbench 1.3. Xicon allows you to 
execute CLI only batch files and 
programs by clicking on an icon. I 
haven't tried this fix with eidier of these 
programs, but it is worth the attempt.

The exploding crop of computer 
viruses may be an annoyance for 
computer owners, but they are a real 
headache for software manufacturers. 
Developers need to be especially aware 
of their responsibilities in making sure 
their master disks don't become infected 
by one of the numerous viruses that are 
floating around the computing 
community. It would be easy to spread 
the virus to hundreds, e\'en thousands of

previously uninfected computers with 
just one mistake. Unfortunately this 
problem has occured on several 

I almost hesitate to single out any 
manufacturer by pointing out that their 
originals might be infected, but a 
spokesperson for Sound Quest, 
manufacturer of Texture, provided a 
statement regarding the release of an 
upgrade to this high quality music 
oriented software package which I felt 
presented a clear view of the problems 
encountered by any software 
manufacturer in this age of viruses. 

Unfortunately, in our haste to 
release The Quest I: Texture, tliere 
were several disks shipped with two 
versions of song fiJes. The song files 
NOT in the Song Drawer are the proper 
ones. In addition, without our 
knowledge tiie SCA Virus cropped up. 
Needless to say, this did not improve our 
day. It can be removed by running die 
Install program, using a dean write- 
protected Workbench on the Quest disk. 
This will not damage the program. We 
have learned a real lesson and apologize 
to those inconvenienced. We believe in 
providing software support to our 
customers. And, anyone still concerned 
with their disk should call us witli their 
warranty numb)cr and we will replace 
their disk happily. Tliis is our 12th 
software product for tlie Amiga and we 
hope to provide many more in the 

What we did to The Quest I: 
Texture was to: 

1) Remove the need for the Roland 
MPU-401 hardware 


2) Maintain its ROCK-SOUD timing. 

3) Provide a comprehensive pull- 
down menu/mouse/keyboard 
screen display. 

4) Reduce the list price of Texture 
from $700 to $150.

While on the topic of viruses, a 
program that everybody should have in 
their startup-sequence, VlrusX, has been 

upgraded to version 2, VirusX, once 
executed, remains active and unnoticed 

until you put an infected disk in the 
drive, whereupon it notifies you of chat 
fact. Viru.sX is public domain, and 
available on information sen'ices and 
bulletin boards ever>Tvhere as well as the

3-Demon is a graphics program 
from Mimetics that has just recently been 
upgraded, adding several new features 
including ilie ability to save Turbo Silver 
2.0 files, VideoScape Binary files, and 
Wavefront files. Also, bug fixes and 
improvements have been made to the 
package. Previous owners of the 
program can get an upgrade from 
Mimetics for just seven dollars to cover 
postage and handling. Send them your 
program disk and a check or money 
order for $7.

Harry Evangelou has recendy 
been hired as Haitex's X-CAD product 
manager. Harry has recently completed 
two add-on programs for use with X- 
CAD. A HPGL to X-CAD converter allows 
users to import their symbol databases 
from otlier packages until the DXF 
reader arrives, and an IFF brush to 
screenmenu convener that allows users 
to use any of the IFF drawing packages, 
such as Deluxe Paint to design custom 
menus. Harry has also created a custom 
menu template with several highly 
productive features. 

These files have been made 
available to X-Cad users and can be 
found on Bix, CompuServe, PeopleLink, 
and other BBS systems by now, If you

The Amiga Gets Smart 

by Steve Gillmor 


Remember the day you first turned on your Amiga and entered the multitasking 
world of computing. How about the thrUl of DPaint 2, where you suddenly had a 
Paintbox on your desktop witii features and effects rivaling those previously available 
only at two or three hundred dollars an hour. 3D animation and raytracing you can't 
buy at any price. Desktop video when desktop publishing was barely out of its 

In every aspect of computing, the Amiga has ventured where no computer has 
gone before, pushing out at tiie boundaries of the state of the art while offering power 
at prices so low they brought in the first-time user in numbers now nearing one 

Now comes the worid of artifical intelligence in the form of MAGELLAN, expert 
system software for the Amiga from Emerald Intelligence. With the aid of a well- 
written manual, you can jump right in, but first let's backtrack with a little history. 


The story of AI is really the story of 
computing at an early crossroad. With the 
end of World War II, American and British 
scientists began applying their resources 
toward the development of what was to 
become the computer. Each team began with 
the same basic system-. An electronic 
machine driven by stored program directions 
to carry out numerical calculations. The 
British wanted these instructions to be based 
on logical operators such as "and," "or," and 
"not." These operators could be used to 
assemble more specialized numerical 
operators for arithmetic calculations, and to 
manipulate symbolic material such as 
statements in ordinary language. 

The Americans, however, were more 
interested in a simpler, faster machine to do 
arithmetic calculations, so they used 
numerical operators such as "+," "-," "<," etc. 
The British went along with this and 
confined AI work to a loose consortium of 

computer scientists and psychologists in theoretical research at the university level. In 
1950 Alan Turing, leader of the British team, tested the theory of "machine intelligence 
in a paper entitled "Computing Machinery and Intelligence." He posited placing a 
human in room A, an "intelligent" computer in Room B, and a second human 
"interrogator" in Room C. He or she communicates with Rooms A and B via teletype, 
and does not know who or what is in which room. If the intenogator cannot 
distinguish between the two responses then the computer in Room B is declared "as 
intelligent" as the person in Room A.

Backward chaining has terninated, 

That was the theory. Getting a computer 
sman enough to do that, or a human smpid 
enough, has occupied much of the past fort)- 
years. It is only now with the advent of 
high-speed powerful chips and sophisticated 
software that we are learning how to 
inculcate a machine with the properties of 
the "expertise" of the human in various 
disciplines. Most expert systems work by 
encapsulating the knowledge of the expert 
in a series of IF-THEN rules. These rules are 
made up of the stuff of what we call 
intelligence: facts and heuristics, or ailes of 
thumb. This surface (or experiential) 
knowledge is distinguished from deep 
knowledge of formal principles and tlieories. 
Existing exfjert systems only provide good 
advice when they are used to assist users in 
solving problems that lie within narrowly 
defmed domains. One good rule of diumb 
for MAGELLAN is that IF you can do 
something with your Amiga, THEN the 
chances are good you can do it under 
control of a rule base. 


Let's do just that: Fire up MAGELLAN 
and go through its paces under the "control" 
of its 132-page manual and two disks, the 
program on a bootable 1.2 Workbench, and 
a data disk ftiU of sample knowledge bases. 
The manual is divided into tliree main 
sections: Level One, a Menu Options 
Overview; Level Two, Usage of the afore- 
mentioned Options; Level Three, Getting 
Started and a walkthrough tutorial on 
building a small expert system. A glossary 
that efficiently brings you up to speed in AI 
terminology follows, and an Appendix 
Introduction to Al runs the gamut from 
answering "What is Artificial Intelligence?" to 
"What applications has AI been successful 

(Top) On opening MAGELLAN, the bottom 
of the screen is filled with the DIALOG 
uAndow, which acts as an interactive 
message board. The top third of the screen 
is the CONTROL window, where help 
messages are displayed upon request. 

(Bottom) Build rules in the Rulebuild 
window using a simple, English-like 

The Components 

An Introduction describes the three major components of expert systems: 

1. The Inference Engine - the program that makes decisions, asks questions, and 
does the 'work'. 

2. The Interface - all of the software and hardware that connects the Inference Engine 
to the outside world including input via menus, keyboard, mouse, sensors, etc, and 
output through screens, -windows, printers and displays. 

3- The Knowledge Base - what the expert system knows about. An expert system to 
diagnose an automobile would have a specialized KB containing info about carburators 
and alternators. 

32 Amazing Computing V3. 12 ®1988 

This separation of powers, if you 
will, is one of the secrets of AI. Ninety 
five percent of tlie time spent debugging 
computer software is writing, waiting for 
compilers to compile, linking, re-editing, 
compiling. Witli knowledge-based 
programming, you change a rule, click 
and enter it, and that's it. MAGELLAN 
lets you break down a problem into 
simple IF-THEN rules that you enter in 
simple sentences like; IF car is not 
starting AND weather is rainy, THEN 
distributor cap is cracked. As few as 10 
or 20 rules can form a useful system. But 
unlike software where -we may never see 
DeluxePaint 3, we can change and add 
to the rules of a knowledge base to 
respond to new information as we get it. 
The Inference Engine remains intact, but 
the separate Knowledge Base and a 
variety of inputs changes. 

You're in CONTROL 

When you load MAGELLAN you 
come upon two windows set against 
the Emerald Intelligence green color 
background. The bottom of the screen is 
filled with the DLALOG window, which 
acts as an interactive message board. The 
top third of the screen is the CONTROL 
window, where help messages are 
displayed upon request. Clicking in die 
CONTROL window with die left button 
allows you to activate the Menu Options 
with the right button. There are seven 
general categories as you move left to 
right: Session, Rules, Cells, Words, 
Inference, Display, and Explanation. 

Session is just another word for 
Project, and its choices are basically 
familiar functions with the vernacular of 
expert systems. Khowledge bases are 
composed of rules; rules are made up of 
object, attribute, and value. For 
example, IF ftir (objea) color (attribute) 
is brown (value), THEN dog (object) 
type (attribute) is watchdog (value). 

So the Session sub-menu gives 
you the choice of Loading a complete 
Knowledge Base, Loading or Saving 
specific sets of values, Clearing all 
inputed values, Help, Quit, or Status 
Display. The latter displays current 
program and system information 
including the current directory and 
existing knowledgebase files as well as 
the number of rules, words, and cells in 
the current KB. This command offers 
immediate gratification at any moment, 
something you will appreciate as you 
fijmble your way toward Intelligence, 
Artificial and otherwise. 

Commands added since printing 
the manual include Lock, a feature for 
use in testing different combinations of 
rules and values, and New CO, which I 
am using right now to multitask with 
Scribble! as I write this article. Also 
added since the manual went to press 
are opdonal keyboard commands for 
most menu items. 

Rule Options include: Select, 
Create, Display, Save Rules, Edit, Delete, 
and Help. You can enter new rules with 
Create, or change existing ones by 
Selecting, then Editing or Deleting. 
Saving Rules allows you to store tested 
rules in a separate file and "back up" a 
current rule base while experimental 
changes are made. Help, as with all 
such menu choices, directs you to the 
appropriate pages of the manual. 

Cell Options are Select, Display, 
and Help. Each rule created, 
automatically creates a cell. A cell is one 
of a number of combinations of the 
object, attribute, and value (OAV triplet) 
in a rule. We'll get back to cells in a 
minute, but they are important because it 
is by Selecting cells that you can attach 
variables, text files, images, or 
programmed functions to an individual 
cell to expand the complexity and 
intuitive reasoning of your expert system. 

Words Options allow you to Add 
Words, Display tlie dictionary list of 
word and phrase entries, create 
Synonyms, and Edit mispelled words or 
change them to another word. Such 
changes are automatically global in the 
rule base. Help is a Synonym for Pages 
59-64 in the manual. 

It's Logical 

Inference is defined in the 
glossary as "The process by which new 
facts are derived from established facts." 
Our Menu choices in the manual are 
Backchaining, Forward Chaining, and 
Synergistic. MAGELLAN tries to derive 
the information it needs from the rules 
already in the system before it quesdons 
you for input. Let's recall that rule about 
the dog. Backchaining is initiated by a 
goal. The system attempts to determine 
a Value for the goal and identifies rules 
that conclude with a Value for the goal. 
If the goal is "watchdog", then the rule 
that pertains is our "fur type is brown, 
THEN dog type is...." So having located 
that rule, the process then Backs up and 
attempts to determine if the IF clauses of 
the related rules are true by determining

values based on yet other rules. 
Evenmally the backchaining sequence 
arrives at either a pause as it asks the 
user for information it doesn't have, or it 
may halt with the result stated as 
unknown. Successful backchaining can 
result in an answer to the original goal; if 
more than one solution is possible, a list 
of acceptable solutions is displayed. 
Forward Chaining begins by 
reviewing the known facts and then 
"firing" all the rules whose IF clauses are 
true. The system then begins another 
cycle, checking what additional rules 
may now be true, and so on until the 
program reaches a goal or runs out of 
new possibilities. Synergistic inference 
uses both backward and forward 
chaining, backchaining to resolve a goal, 
then moving forward to locate ail 
associated conclusions and triggering 
related processes like IFF and text files 
or external program commands. 
Synergistic is the default mode, since its 
result reflects the most comprehensive 
up-to-date analysis of information 
available to the system. 

Attempt and Goals 

Scrolling down tlie Inference 
menu, you come to several important 
additions to the program, Attempt and 
Goals, documented in MAGELLAN 
Manual Supplement 1.0 included in the 
package. With Attempt, the goals you 
initiated Backchaining with previously 
can no'w be created, once prioritized and 
stored with a knowledgebase. As the 
knowledgebase is retrieved with the 
Load KB command from the Session 
menu, the saved goals are restored. 
Goals Option has a sub-menu with 
choices to Add, Delete, Display and 
Clear. By selecting Attempt you initiate 
Backchaining in decreasing order of 
priority from 100 (high) to (low). All 
in all, a neat time saver that encourages 
experimentation and automates the user 
interface for those of us like me who 
appreciate digital hand-holding. 

Display Options 

Display Options include Preview 
Picture, Output Mode, and Results Mode 
(the latter yet another recent addition). 
Preview lets you search for graphics or 
pictures without leaving MAGELL-^. 
Output can be directed via a sub-menu 
to Screen, Printer, or File. A Voice setting 
is grayed out, indicating a "hook" to be 
activated in revisions forthcoming soon. 
Default is to the screen, of course, but 
you can direct to multiple destinations 
simultaneously. Occasionally, it is 
desirable to suppress the display of 
resolved information and goals during 
backchaining. Results Mode allows this, 
and via tire Wait sub-menu command, a 
time delay between results windows. 

Let me Explain 

Our last Menu Option is 
Explanation, and not a minute too soon. 
But seriously, these options show the 
path of reasoning used to conclude the 
current result. Why? explains why 
information is requested, The rule clause 
being investigated is displayed as well as 
the value sought to prove die rule. 
Trace shows the path of reasoning that 
was followed to get to a particular result. 
This is especially helpful for the 
beginning Knowledge Engineer, as it 
shows how tlie system came to its 
conclusions and where the rule base 
took any wrong turns. As tlie manual 
points out, expert system development 
programs are called shell programs 
because they themselves contain no 
knowledge about a problem, but instead 

enable you to create your own expert 
systems rapidly. You - the expert - teach 
the computer how to solve the problem 
by entering rules explaining the steps 
involved in the decision -making process. 
Wliy? and Trace are like litde windows 
into MAGELLAN'S brain; if MAGELLAN 
asks tlie wrong question or returns an _ 
unexpected result, these options let us 
track down where we went wrong and 
help to correct our reasoning. 

Creating a Rule 

Now that we've checked out the 
Menus, MAGELLAN is ready to go. So 
are we, once we've learned a few more 
terms as we explore Level Two. The 
manual navigates back through the menu 
selections, this time in depth. We leam 
how to create a rule, opening the 
Rulebuild window and entering rules in a 
simple, English-like mediod. The first 
box below the IF statement is the Object. 
The Attribute goes next to the right, and 
can best be defined as a characteristic of 
the object. The attribute in turn is best 
described by the Value. 

In between Attribute and Value is 
the Operator. It characterizes the 
relationship between the contents of 
these two elements. Operators describe 
various relationships including: 

verbal - 

is, is not, are, are not. 
mathematical - 

less than (<), greater than (>), 

<-, >=, =,!=. 
Special (in THEN Result clause) - 
Execute ($), Print (!), 
Show (*), and Parse(5*). 
These operators execute an 
AmigaDOS command, start a 
printing job, show an IFF image, 
and parse ati equation to solve a 
dependent variable. 

Also explained are threshhold and 
certainty values entered to the right of 
the values in the Premise and Result 
clauses respectively. A threshhold value 
of .20 represents the minimum degree of 
certainty a condition must possess before 
the related rule will be recognized by the 
inference process. A THEN clause that [ 
dog ][ type ][ is ][ watchdog 1I.501 implies 
that there is a fifty percent chance (a 50% 
chance of being 100% certain) tliat the 
dog type is watchdog, IF it is determined 
that the [ fur ][ color ][ is ][ brown ![.201. 
Clicking on the Auto gadget sets default 
threshholds at .20 and certainties at l.CX) 

34 Amazing Computing V3.12 ©1988 

which is good enough for most rules. 
ReaJ-world problems rarely have absolute 
answers. Confidence factors, like 
ihreshhold and cercaincy, allow you to 
include rules that imply or suggest a 
solution, but are not absolutely 

More on Ceils 

That reminds me: I promised to 
get back to cells, didn't I. By Selecting in 
die Cell option, you access the Cell Edit 
window. This contains boxes for the 
now familiar Object, Property (don't 
worry, it's a synonym for Attribute), 
Operator, and Value. Right and left 
arrow gadgets below the Object box are 
clicked on to locate particular OAV cells 
from the rule base currendy in memory. 
Also displayed are gadgets labeled 
Legals, Variable, Inquiry, and Info. 
These buttons allow you to attach 
gadgets, files, and variables holding 
floating point numeric values to cell 
values. Selecting the Cell Display menu 
option helps you to see if values need to 
be cleared out before discrete inference 
processes, and, as with all edit windows, 
this one can be resized and put away by 
clicking on the box in the upper left 
comer of the display window. The 
program remembers all resizing and 
screen relocations. 

Applying AI 

Level Three, Getting Started, 
begins witli some general suggestions for 
how to go about applying artificial 
intelligence techniques to real-world 
problems. It recommends using expert 
systems where the technology is useful 
and appropriate, anticipating the usage 
by providing users with easy, simple to 
use "handles", augmented with graphics, 
audio, and text explanation. It is 
strongly suggested to focus the problem 
tightly, breaking it down into smaller, 
specific problems. Many problems can 
then be handled with just a few rules. 
MAGELLAN can handle up to 100 rules 
in 512K, and will hold several thousand 
rules on a fully configured Amiga. 

The tutorial is based on a 
diagnostic system of symptoms and 
possible failures of chips in the Amiga 
1000. IF symptom is a black screen with 
a white bar OR symptom is a black 
screen only, THEN possible failure is 
Agnus Chip (8361). Rule entry is 
demonstrated with various screen shots 
and explicit directions. Be sure to pay 
attention to carriage returns, and make 

sure to click in the appropriate window 
before entering characters. (It is 
somewhat annoying to navigate between 
Dialog and Control windows via left 
button mouse clicks, but it is rumored 
that updates will advance the user 
interface to reflect the sophistication of 
the rest of the program.) 

The various symptoms and 
appropriate failures are reduced from 
seven chart entries to four rules. The 
program automatically checks each rule 
when entered for recursion, so that 
backchaining does not send the program 
into an endless loop. Now it's time to 
test our first rule - first Clear All from die 
Session menu, This clears all certainties 
to zero prior to execution, and can be 
checked by Displaying in the Cell Option 
menu. If cleared, all cell values wUi be 
"unknown." Then we select the 
backchain option of the Inference menu. 
The Dialog screen wiU read 
"Backchaining Goal Entry; hit <CR> to 
begin." Click in the lower window and 
do just that; the system wUl now request 
the Object to reason about. It is looking 
for the Object of the THEN clause of our 
rule about [ Possible ][ Failure ], so enter 
"Possible" and <CR>. The system 
"knows" about possible failure, so it says 
"The system can reason to determine: 
What is the Possible Failure" and tlien 
"What Attribute do you wish to find out 
about 'Possible'?" We enter "Failure" and 
<CR> and a new window opens. 

The Data Entry window is 
MAGELLAN'S way of asking questions. It 
asks "Is the Symptom A Black Screen 
Only?" and if you click on the no button 
at the bonom, comes up again to ask the 
second IF clause of the original rule, "Is 
die Symptom A Black Screen With A 
White Bar Only?" If you dick yes, you 
have given the system a Value that it can 
use to resolve the search for the goal, 
and the final result is given in the form 
of a Conclusion that is displayed in its 
own window: die Possible Failure is 
Agnus Cliip (8361) [certainty = 1.000000]. 

A Great Start 

The tutorial concludes by showing 
how to bring up an IFF image in 
conjunction with die conclusion, and 
how to use MAGELLAN to generate legal 
values as suggested responses to 
quesdons. Included on the data disk are 
several sample knowledge bases that are 
worth loading and examining with the 
various Display options to see how rules

are constructed and how cells fill up as 
you Attempt back and forward chaining. 
You may have some difficulty in getting 
IFF pictures to come up, but make sure 
to direct die pathway to the data disk as 
KBasesiAgnus, for example. Or load 
your images into RAM for faster display. 

That's aU folks! 

That's as far as MAGELLAN goes 
in its Intro package. Once you've spent 
some time playing with die rules you've 
entered in the tutorial, and dissected the 
data disk examples, you may wonder 
what to do next. Don't discourage 
yourself by attempting too complex a 
system. Start by training yourself in how 
to reduce an everyday situation into a set 
of rules. 

A good way of generating rules is 
by describing how you go about solving 
a problem. For example, let's say you 
want to figure out what to do tonight. 
There are a variety of options: Go to a 
movie, take a walk, get some Chinese 
food, stay home and use MAGELLAN to 
figure out this problem - no, that might 
be recursive! Each of these alternatives 
can have associated facts and rules of 
thumb. IF you like movies AND IF it's 
not raining THEN you might Go To The 
Movies .70 certainty. A further rule 
might relate to your preferences for 
comedy over drama, etc. You can see 
how quickly such a simple question can 
begin to generate rules. And then you 
have to factor in what your better half 
wants to do. You'll soon be developing 
an expert system on just who I wears the 
pants ] in this house, let me tell you. 

MAGELLAN, don't forget, is an 
Introductory package. It is also the first 
release of the first micro-based multi- 
tasking AI program. As such, it is strong 
on concept, deep in access and hooks to 
emerging technologies, but also tentative 
in interface and right-now application. 
This is as it should be; the .Amiga user 
base is growing rapidly and many are 
new to computing in general. There is 
plenty to sink your teeth into now with 
MAGELLAN, and by the time you've 
learned how to choose an area for 
knowledge engineering and apply 
MAGELLAN to its domain, Revision 1.1 
will be on the scene, Free to registered 
MAGELLAN owners for' one year, 
additional features and improvements are 
promised including: 

Arexx front end — 

Currentiy, MAGELLAN can 
command the execution of Arexx macros 
via the 'S' operator in the result clauses 
of rules. With the Arexx interface, it will 
be possible to use MAGELLAN as a 
"Knowledge Server" to provide AI 
inference processing on demand from 
other, Arexx-supportive programs. 

Inference loop mode — 

continually 'waits' for new data 
and responds. 

Real time clock — 

automatic creation of 'Current 
hour', etc., cells and tlie upkeep of their 
current values. In combination with loop 
mode, a powerfijl feature. 

Improved Rule-Management 
Tools — 

better display, editing features 

More 'Meta-Logic' — 

greater control of MAGELLAN 
features from within a knowledge base 
itself — to allow users to control 
knowledge base loading, clearing values, 
etc., under rule control. 

These revisions will go a long 
way toward answering the questions that 
need to be asked of MAGELLAN. The 
appearance of AJ applications in the 
Amiga market is significant; there is an 
enormous body of research and 
commercial application in expert systems 
available for study and incorporation. 


With the proliferation of "main- 
frames on a chip" goes hand-in-hand an 
explosion of information and the need to 
manage it. Expert systems are here to 
Slay; they're embedded in your VCR, 
your coffee-maker, your cash machine. 
MAGELLAN gives you the keys to the 
future, as in: Gentiemen and women, 
start your [ inference ] engines!

' Incredible multisampled sounds 
in SoundScape and IFF formats 

by Tim Mobansingb 

Long before MIDI, and even 
before the personal computer, there was 
the first sampling keyboard. It didn't 
have a single byte of memory yet it 
could play back samples seconds long. 
It was the Mellotron, played avidly by 
many, including the Beatles and the 
Rolling Stones. Just listen to Days of 
Future Passed (The Moody Blues) or 
Strawberry Fields Forever (The Beades) 
to hear the "mutative organ". People 
reproduced anything by recording a 
sound onto a dozen closed loop tapes (it 
was the first multisampler, too!) and 
controlling the tapes with a Rhoads sized 

The technique to play notes 
ranging between the twelve samples was 
the same as it is now, The tapes were 
played faster to get higher notes. Today, 
tajses and speeds are replaced by bytes 
and sampling rates. A recent 
introduction to this modem musical 
software corps is E.C.T. SampleWare, 
created by Drew Neumann and Todor 
Fay, the programmer of SoundScape. 
The samples from E.C.T. were generated 
with the Mimetics SoundScape Sampler 
using the SoundScape Pro Midi Studio. 
Four disks are currently available in 
either SoundScape or IFF format Rock, 
Orchestral, Grab Bag and Digital 
Synthesis, containing a total of 88 
samples. These will be reviewed here 
along with some comments on their 
application and background. 

Why sampled sound? 

Sampled sound has a distinct 
advantage over traditional synthesis 
because the character of the sound 
doesn't depend on a particular kind of 
hardware or software. Not only can you 
reproduce traditional stationary tones, 
but complex, evolving patterns can also 
be created. When the sound has a 
regular pattern, it can be looped to 
create a continuous sound, a feat difficult 
to accomplish with traditional 
synthesizers. The E.C.T. samples contain 
several gems that take advantage of this 
ability. ElectroBoil and ElectroBubble 
are two examples that sound exacdy as 
they read. 

Measuring up 

The piano imitation in any sample 
package (or synthesizer) often serves as 
a good measure of the instrument's 
overall quality. The piano for E.C.T. was 
multisampled for 5 octaves, and like all 
the other samples, has good fidelity. The 
E.C.T. piano is over 50% bigger than the 
IFF piano sample from Deluxe Music, but 
shows considerable improvement in 
character (thanks to multisampling) and 
less aliasing distortion (the benefit of a 
higher sampling rate). The envelope 
settings needed a little adjustment, 
however, when first loaded, the velocity 
sensitivity was zero (not good for a 
piano with any feeling) and the attack a 
little too sharp. Softening the attack was 
necessary' to eliminate some bothersome 


I usually don't get too excited 
when somebody hands me a grab bag of 
sounds because it's difficult to find a 
practical application for a nutty variety 
pack. In Grab Bag, though, there are 
many noises that actually sound musical. 
Careful thought went into the production 
of masterpieces like Glug Glug, Wet 
Blorch and Wacky Flower Pot. Grab 
Bag has sounds that will work as the 
spice for your music, or even as 
alternative rhythms. 

Digital Synthesis is the newest 
addition to die E.C.T. SampleWare 
collection and has some of the most 
gutturally impressive sounds. The deep 
vibrations coming from Gnarly Stack and 
Phlangarama make the Amiga sound 
much bigger than it looks. 

Rock has pretty much what you 
would expect, samples of all sorts of 
guitars: stacked, fuzzed, clean, acoustic 
and synthetic. The drum kits are 
excellent. Orchestral is also pretty 
straightforward with wind instruments, 
strings, horns and percussion. Orchestral 
Hits is a very spieciai sample tliat is 
guaranteed to keep anyone awake 
during your music. It's a snapshot 
collection of the "bangs" where an entire 
symphony is blasting the same staccato 
note. Pretty impressive. Overall, 
Orchestral demonstrates well tlie night 
and day difference between professional 
samples and home samples. 

38 Amazing Computing V3.12 ©1988 

What do you get? 

On ±ie outside, the E.C.T. 
package comes with a 7 page booklet, 
and the four descriptively labelled disks. 
The booklet describes what went into 
making die samples, how to use the 
samples widi your system (whether it be 
SoundScape or an IFF compadble 
application), and how to custom tailor 
the samples to fit in less memory. It also 
describes how to use SoundScape to 
create a vibrato effect. 

AU this and IFF too! 

For folks who don't have 
SoundScape and want to use the IFF 
samples with other software, E.C.T. also 
offers multisampled sounds in IFF format! 
Using proprietary software written by 
Todor Fay, separate sounds were 
recorded on different octaves and 
combined into one sample. 
Multisampling preserves the quality at 
higher and lower octaves for wide range 
instruments like the piano, and is 
indispensible for creating a good drum 
kit. The IFF samples also have icons 
allowing them to tie dragged into 
different directories without using the 
CU. This is handy for people with 
Instant Music and other software that 
need sounds in a special instrument 
directory. Sonix users will need to 
rename their samples witli tire suffix 
".instr". In addition, Sonix users will 
need to play with the keyboard note 
assignments in order to hear the sounds 
once they are loaded. 

The Making of a Sample 

Creating a good sample takes a 
few tricks: First, good audio equipment, 
and then careful attention to sampling 
rate, envelope and loop point. 
Unfortunately, even with the most careftil 
setting of the looping point, nasty clicks 
can show up in the sound. Todor Fay 
got rid of this problem by using a 
crossfade module in SoundScape (see 
Amazing Computing volume 2, number 
9). By crossfading the beginning of a 
sample witli the end, smooth transitions 
occur as die sound is held. Most of the 
time crossfading works well. It was used 
heavUy with die E.C.T. sampleware to 
ensure that the samples could be 
sustained without distracting attention. 

Make those sounds more 

AU sampled sounds have an 
inherent disadvantage, they sound 
exacdy the same every time they are 
played. That's why it's hard to sample a 
saxophone and fool anyone into diinking 
what you then play is live. Quite often, 
acoustic instruments depend heavily on 
drastic variations to make the sound alive 
and to convey a human feel. So when a 
guitar or flute is sampled and used to 
play a sequence, it can be pretty dull. 
Fortunately, there are several tricks you 
can use to make samples sound more 

1. You can add a vibrato to a 
sound in SoundScape by using a 
pitchbend track and the Tapedeck. This 
is explained in the manual that comes 
widi the samples, and an example track 
sequence is provided on the SoundScape 
version sample disks. Vibrato generated 
this way is very realistic since it is 
independent of the sampling rate. That 
means no chipmunks as you play 
different notes, the vibrato rate doesn't 
change. NICE. 

2. The Echo module in 
SoundScape (see Amazing Computing™, 
Volume 2, Number 5) does wonders for 
a sound by improving the depdi and 
hiding litde glitches in the sample. 
Aldaough it's expensive in terms of the 
audio resource (you may not be able to 
play more than one sample when using 
Echo), this effect can turn an other^'ise 
dull instrument into a great solo. Synth 4 
on the Rock disk sounds incredible with 
an Echo effect. 

3. If you don't want to go as far as 
the Echo module, things can still be 
improved for lush sounds by lengtliening 
the envelope to get soft fades. Here 
again is a compromise between smooth 
sound transitions and running out of 
audio channels. 

4. Pay attention to your playing 
style. Hold notes just long enough to 
hear the character, then let go or play 
something else before looping becomes 
obvious. This may hie hard to do if you 
are playing a piece by strict time, but 
keep it in mind when composing. 

You may fmd that just as everything is 
fattened up to where you like it and 
you're ready to add the drum track, 
you've run out of audio channels. The 

next step is to add an external 
synthesizer and control it with MIDI to 
get the extra sounds. Alternatively, the 
combinadon of an inexpensive 
synthesizer and the Amiga playing notes 
together (called stacking) can make very 
impressive single sounds diat imitate 
much more expensive keyboards. 

Sampling rates and filters 

For someone with lots of memory 
and a picky ear, sampling rate becomes 
an important issue. Sampled sounds on 
the Amiga have until now depended on 
a hardware filter to eliminate aliasing 
distortion caused by a low sampling rate. 
Now the fJter can be switched out with a 
software button and many want to hear 
the higher frequencies that the Amiga is 
capable of reproducing. The E.C.T. 
samples were sampled at 14 kHz, which 
is a reasonable compromise between 
high fidelity and nicely sized samples. 
Another solution which would allow the 
user to make compromise decisions 
would be to sample the sounds at the 
maximum rate (about 28 kHz) and dien 
provide a filtering program that would 
allow sample sizes to be reduced when 
memory is short. 

Good stuffl 

The bottom line criteria for a good 

sample is musical utility. Answer the 
question: Can I really use this sample? 
E.C.T. SampleWare was designed with 
this principle in mind. The sounds were 
professionally recorded and well 
groomed characteristics thai are hard to 
get w^ith a home sampler and litde 
patience. If you're interested in trying 
these samples for yourself, send an order 
with S24.95 for one disk or $79.95 for all 
four to;

Wargame of the Century 


by Stephen Kemp, PUNK: SKEMP 

EMPIRE has finally made it to the Amiga — perhaps one 
of, if not, THE greatest computer game ever written! I have 
waited and waited for this game to appear on the Amiga, Now 
that it has, I am not disappointed! 

Ancient History 

Many of you may be familiar with previous versions of 
EMPIRE that were available on other machines. EMPlIiE was 
originally written by Walter Bright while he attended Caltech. 
Later he rewrote the program to run on the PDP-11. After that, 
many people became "addicted" to tlie game and it was destined 
to migrate to other machines. A version of EMPIRE was translated 
into C for the IBM PC around 1984. Although that program was 
being marketed, like all popular games, imitations sprang up in 
the public domain. Mr. Bright and the marketers of EMPIRE may 
have been "annoyed" by these unauthorized duplicates, but it 
may all turn out to dieir advantage. Once it becomes known diat 
this version of EMPIRE is the greatest yet available, EMPIRE 
"addicts" will not be able to resist. 

The Warning 

Yes, EMPIRE is -addictive". I have been an EMPIRE 
addict for many year. When I heard diat INTERSTEL's EMPIRE 
was going to be distributed by EA, I thought how 
appropriate. ...EA — Electronic Arts or maybe EMPIRE Anony- 
mous. Apparendy, INTERSTEL was concerned enough about 
the addictive nature of the game to include this warning on 
the box: 

■EARNING: This program is highly addicti\'e. Consider- 
able otherwise productive time might be lost. Play only during 

Do not take diis warning lighdy. Believe me, once you 
start this game, all sense of time is lost. Hours will pass by in 
seconds and days will pass by unnoticed. Before you know it, 
you will be just like me, an EiVIPIRE addict. You will look at 
your watch at 3:00 AM and say, "Oh, I'll go to bed just at soon 
as I do this one thing," And after that one thing is accom- 
plished, you will say it again, and again. 

40 Amazing Computing V3.1 2 ©1988 


EMPIRE is a game of conquest. 
INTERSTEL has done a nice job of 
working the scenario into its Star Fleet 
saga. You are sent to a planet to conquer 
the inhabitants and increase the reign of 
the EMPIRE. However, one or more of 
your EMPIRE'S enemies have the same 
intentions. Now it is more than a simple 
conquest, you must also eradicate your 

Planetary conquest is accom- 
plished by bringing the planet's cities 
under your control. Once you have cities 
under your control, they can be directed 
to build armies, fighters, and ships so 
that you can expand your control and 
plan to meet your enemy. When you 
finally do meet the enemy it will be a 
test of strength and endurance. Ulti- 
mately, the one who makes the most 
strategic use of their resources will be 
the viaor. 

EMPIRE is not disk copy-protected 
but it is play-protected, which means that 
you are annoyed at the beginning of 
each session by having to type in a word 
from the documentation. The only 
problem I have with this protection 
method is that nobody seems to imple- 
ment it properly. When they ask you for 
a word, they give you tiie word number, 
the line number and then the page 
number. When you look it up, you need 
the page number, the line 
number and then tlie word 
number. Am I the only one 
who has noticed that they 
give it to you exacdy 

War Pieces 

In order to take over 
a planet and defeat your 
enemies you will need a 
number of war units. Here 
is a brief description of the 
pieces that you can make 
during a game: 

Armies — These are 
the most important units 
when conquering a planet 
and fighting a war. Armies 
can be produced in tlie 
least amount of time and 
are the only piece that can 
conquer cities. This makes 
them indispensable, since 
you need cities to make 
more weapons. 

Fighters — • Unsurpassed in their 
ability to quickly discover new territory, 
the fighters are also good in combat. This 
is due to the fact that fighters can "move" 
a greater distance in a single tum than 
any o±er piece. This gives them the 
ability to get to the front quickly once 
the enemy is detected. 

Troop Transports — Troop 
transports are used to move armies 
between continents. They are not well 
suited for combat, but will perform when 

Submarines — One of the most 
useful batde units in the sea is the 
submarine. They are hard to detect by 
your enemies and can inflict tremendous 
damage when they attack other vessels. 

Destroyers — These are the fastest 
ships. Because of their speed, they can 
be sent to enemy sightings quickly. 
Destroyers are good in battle and as 
escorts for transports. 

Cruisers — Cruisers are not as fast 
as destroyers but are much stronger. 
When engaging the enemy at sea, the 
cruiser is a good weapon. 

Aircraft Carriers — These are 
large sea vessels which can carry up to 8 
fighters. Since fighters require periodic 
refueling, it is sometimes Liconvenient to 
send them back to a city. Carriers can be 
used to refuel fighters and, unlike cities, 
they can move to where the action is. 

Battleships — The final and larg- 
est unit available to you is the battleship. 
They are heavily armored and almost in- 
destructible when engaging a single 
opponent (unless it is another batde- 

Of course each unit has some dis- 
advantages. The pieces might be thought 
of in the same manner as the old "Paper, 
Rock, Scissors" game. Some pieces are 
not as effective against one type of piece, 
while extremely effective against others. 
Additionally, you have to wait for a city 
to build the units. I have listed them in 
the order of the amount of production 
time required to make each item. Armies 
require 5 turns and batdeships require 
50. A tot can happen in the 50 turns it 
takes a city to produce a batdeship. You 
may have needed the 10 armies that 
could have been produced in those 50 
turns. Also, by the time you discover the 
enemy, the front could be so far away 
from the city making a batdeship, that it 
might not get there in time to help. Don't 
let tlie produaion time prevent you from 
making strong pieces, just keep in mind 
that when you meet the enemy, you 
want to have as large a force as possible. 
That means you will want to have plenty 
of armies, fighters and cities. They are 
the foundation of a strong front.

(Dragons Lair 

by Ra ndy Linden 

Insert Coin 

In the summer of 1983, a revolutionary new game appeared in the arcades. 
This game featured high quality stereophonic sound, the likes of which had never 
been heard in the arcades. But even more importantly, this game dazzled the arcade 
going public with it's high quality cartoon style animation. This game was, of course. 

Dragon's Lair, and the arcade scene has never 
been the same since. Dragon's Lair ushered in 
a new age of high quality graphics for both 
laser disk and nonlaser disk games aUke. 
Gone are the rudimentary graphics of early 
arcade games to be replaced by dazzling, 
realistic displays. 

Seeing Dragon's Lair in an arcade first 
seminated the notion of high quality graphics 
on computers. It seemed only natural that 
similar results could be achievable on a 
personal computer. With that thought in 
mind, the hunt was on for a computer which 
could keep up with the demands of real time 
full screen animation. As it turned out, 
however, the search was difficult and the wait 

Dragon's Lair on a C64? 

Visionary' Design Technologies' first real 
attempt at recreating Dragon's Lair on a 
personal computer was undertaken using the 
Commodore 64, then, the most giaphically 
sophisticated jjersonal computer around. After 
lowering expectations time and time again 
to allow for hardware limitations, it was 
concluded that satisfactory results could not 
be achieved and the idea was put aside to 
collect dust until a revolutionary new 
computer came along. 

This revolutionary new computer did 
come along in 1985 in tlie form of the 
Amiga which astounded everyone with it's 
graphic and audio capabilities. However, it 
was not until two years later, when the 
Amiga had matured sufficiently, that the 
project became truly feasible. Whjls the 
actual computer was there, there was 
neither the support software nor sufficiently 
powerful hardware to aid in tlie 
development of the game. 

Why wait for tbe Amiga? 

The Amiga's most important trait, from 
the point of view of the game, is the 
incredible color graphics. While many 
other computers are capable of acliieving 

(Top and Bottom) Scenes from the Amiga version of Dragon's Lair.

similar results, few can do it as well, 
and even fewer can claim that every 
owner will be able to achieve such 
results. Further, the Amiga lends itself 
to graphically intensive operations 
because of it's bliner coprocessor. The 
bUtter can, in effect, take over some of 
the more mundane operations from the 
microprocessor and, as well as 
executing them faster than the 
microprocessor, frees it up to work on 
more sophisticated operations. 

It is tliis splitting of 
responsibilities between the 
microprocessor and the blitter which 
allows for the very advanced 
compression techniques diat are used 
throughout tlie game. Similarly, more 
efficient and better sounding audio 
compression is made possible by this 
unique combination. Unlike the 
industry standard IFF format with it's 
limited compression abilities, die VDT 
compression formats push the machine 
to it's limits. These new formats 
achieve significantly better results with 
a combined increase in play speed and 
a decrease in storage requirements. 

Animation with CAST 

The Amiga's unique blend of 
inherent graphic abilities and processing 
speed makes it ideally suited for 
animation. It was this combination 
which convinced Visionary Design 
Technologies to begin working on a 
powerful Cel Animation Sequencer 
Tool, code named CAST. This program 
would allow cartoonists to easily 
animate with their computer while 
emulating some of the processes they 
were accustomed to from classical 
animation techniques. CAST may yet 
be released commercially if sufficient 
interest exists within the Amiga 
community to justify the completion of 
this very large project. 

It was while trying to come up 
with a creative demonstration of die 
power of tlie CAST package tliat the 
idea of resurrecting the computer 
version of Dragon's Lair, now under the 
official title of Don Bludi's Dragon's 
Lair, came up. From our point of view, 
this course of action had two 
advantages. First, the animation was 
already done, so we had only to digitize 
and touch up the actual animation 
frames. Furthermore, the product 
would have an easily recognizable 
animation sequence to show off it's 

power. Don Bluth's animation is 
recognized intemauonally as being of 
the highest quality, and is a perfect 
compliment to the technical excellence 
of the CAST animation system. 

Looking back 

Our first step was to research the 
market for all currently applicable 
hardware and software to make the task 
at hand easier. After an exhaustive 
examination of all image and sound 
capturing hardware available at the 
time, we finally settled for Sunrize 
Industries' Perfect Vision and Perfect 
Sound digidzers. Of the many digiUzers 
we looked at, their hardware simply 
outperformed the others. They were 
faster, easier to use, and the results 
were much better. The people at 
Sunrize Industries were very helpful 
with tlieir excellent support, and tliey 
produced custom versions of dieir 
digitizing software suited to our needs. 

Digitizing and animation 

Once we had picked our 
hardware, we could get on widi the 
actual job of producing Don Bluth's 
Dragon's Lair. The processing of the 
animation is actually quite tedious as it 
involves digidzing each frame from the 
laser disc, and passing it tlirough the 
hands of an Amiga artist who "lifts" the 
animated parts off the background. 
That is to say, the artist replicates a 
picture which contains only tliose 
images that are currently moving in the 
animadon. This is necessary because, 
even with die fine digitizing equipment 
we had available to us, no two frames 
come out exacdy the same. This lack of 
consistency would have caused all the 
animated characters to appear as 
though they were shimmering. Other 
anists are assigned die task of 
reconstructing the background for the 
given animation sequence. This 
process is very artistic in nature, and 
requires a good knowledge of both 
classical art techniques as well as the 
limitations of the Amiga. It is up to the 
background artist to create the illusion 
of depth and perspective for the 
animation, because the animated 
characters are very two dimensional. 
Once both the foreground and 
background pictures have been cleaned 
up, diey are combined and sequenced. 

The work now passed into the 
laps of the four rotoscop>ers who put 
both sets of imagery together, and made 
sure it was consistent. Along with 
combining the foreground and 
background art, die rotoscopers were 
responsible for making sure all the 
trivial rules were observed; Such things 
as matched color palettes for a given 
sequence, centering and die like, are all 
important for the final product to look 
bodi clean and professional. 

Now for a little music 

Once the animation sequence is 
established, it has to be synchronized to 
the audio track. While this process is 
fairly straightforward for rooms which 
were transferred direcdy from the 
original game, rooms which needed to 
be edited required some audio 
manipulation. As each animation 
sequence was adjusted, the sound had 
to be resynced with tlie video tracks so 
that everything remained consistent. 
When all the sound sequences were 
finalized, we went into the studio and 
digidzed the complete sound track for 
the game widi the perfect sound 
digidzers. The audio was compressed, 
and combined with the animadon to 
form die finished rooms. 

Creating the code 

While the artistic process was 
going on, there were also programmers 
working out the technical wizardry 
which needed to take place before Don 
Bludi's Dragon's Lair on the Amiga 
could become a reality; making the 
Amiga run faster and more efficientiy 
than ever before. As well as creating 
die software which generates the game, 
the actual game, and all of the 
compression algoridims needed to be 
designed and implemented, it was 
decided early on in the project that we 
would cake the original Dragon's Lair 
concept and extend it beyond it's 
arcade rendition. The result was die 
incorporation of an entire arcade game 
in the computer version. This maze 
section pits a smaller animated version 
of the player against monsters in a 
large, omnidirectional scrolling maze. 
The player must find his way through 
the maze and pass through each of the 
animated rooms diat are beliind the 
doors in the corridors. The maze 
portion of die game and all of it's 
support software needed to be written

complete the work. A total of four 
programmers took pan in the effort 
with the overwhelming majority of the 
programming time spent on the 
generation software and player portions 
of the game. 

Another programming Jtrst! 

This game is also unique in that 
it accomplishes several programming 
"firsts" in the Amiga community. Aside 
from the fact that this is the first ever ce! 
animated game for any computer 
anywhere, it is also the Ptrst ever fully 
over scanned video game for the 
.\miga. Add to this it's high resolution 
and interlaced modes, as well as 
stereophonic sound, and you have a 
dazzling product. There are also 
several firsts which are transparent to 
the user. This is the first piece of 
software which can utilize the Writable 
Control Store, or in plain English, tlie 
256k of RAM found in all Amiga lOOO's 
but not normally accessible for anything 
but Kickstart. This, effectively, gives 
Amiga 1000 owners with a 256K 
expander 768K of RAM. That is why 
the game requires an Amiga 500 or 
2000 with 1 Meg of RAM, but only a 

512K Amiga 1000. Another transparent 
but valuable feature is concurrent 
loading; while the game is being 
played, it is also transparently loading 
information from the disk. This is 
accomplished without any loss of speed 
in either animation or audio, and allows 
smooth running animation much larger 
than available memory to be played 
with no interruptions in game play. 

Because of our commitment to 
support as many Amigas as possible, 
we had very serious size limitations on 
the player code which actually executed 
the program. It is, of course, written 
completely in 68000 machine language, 
but was written and rewritten many 
times to improve efficiency and speed, 
as well as to shrink it down. Similarly, 
the generation software is also written 
entirely in 68000 as is the maze portion 
of tlie game. 

Finding the talent to 
make it possible 

We realized quite early on that 
we would quickly exhaust normal 
channels for finding artists when our 
requirements were so higli. We 

decided to be true to our usual form, 
unconventional and find new talent 
through local BBSs. We decided to opt 
for local BBSs for obvious 
organizational reasons, but we would 
be happy to hear from any of you who 
are interested in working on future 
projects. In our experience, many 
people who may not have considered 
working as artists (or programmers, in 
fact) actually make for a great addition 
to the development team if given a 
chance. The response from the BBS 
public was tremendous, and it is largely 
due to the help of the various users and 
SYSOPs that this project was completed. 

Of Drawbridge rooms 
and Hard drives 

When the game was first 
introduced to the Amiga market place at 
a preview at AmiEXI^O Midwest '88 in 
Chicago, the rwo most frequently asked 
questions were "Is the room no one 
ever saw in there?"' and "Will there be 
hard drive support'". The first question 
refers to the Drawbridge room which 
was not seen on most of the Dragon's 
Lair arcade machines, and the answer to 
that question is yes. The second

The internal sound capabilities of the Amiga are better than 
that of any other personal computer These capabilities mean 
nothing though, without quality digital sounds, which up till 
now have been scarce. Sound Oasis gives Amiga owners 
access to a large library of sludio-tested digital samples, by 
using the Amiga's built in disk drive to read disks made for 
the Mirage Digital Sampling Keyboard. Sounds can then be 
played from a MIDI keyboard, the computer keyboard, or 

saved as an IFF standard file. Mirage is a irademafk of Ensoniq inc. 

Transform your Amiga into a professional-quality drum 
machine with this software package. Easier to use than 
hardware-based drum machines because everything is 
displayed graphically on screen. Enter drum patterns quickly 
and easily in real time with visual feedback and editing. Create 
realistic drum tracks with any of the 100 drum and percussion 
samples that are included or use your own unique IFF one- 
shot samples. Dynamic Drums also has full MIDI 
implementation and even becomes velocity sensitive when 
triggered from a MIDI keyboard. 

A powerful MIDI sequencer that takes full advantage of the 
Amiga's sound, graphics, and sophisticated user-interface. 
Dynamic Studio is perfect for professional applications due 
to its sophisticated editing capabilities and SMPTE support. 
It is also ideal for home studios, because in addition to 
sequencing MIDI instruments. Dynamic Studio has a built-in 
drum machine, and the ability to playback instruments 
translated with Sound Oasis.

answer was, unfortunately no, or rather, 
a qualified yes. With the obvious need 
for hard drive support we added this 
problem to our list of programming 
challenges to be overcome. We soon 
realized that to include any typje of hard 
drive support we would require large 
amounts of dme and cooperation from 
the hard drive manufacturers. A 
thorough understanding of each hard 
drive's software and hardware is 
necessary before it can be incorporated 
into the program. Actual hard drive 
code must be inserted into the game 
and this requires that hard drive 
manufacturers release to us their source 

With the help of the fine people 
at Comspec, and their great hardware, 
we set about making it possible. Not 
only is the game installable on dieir 
hard drives, but diis installation is 
transparent to the user. The user has 
only to insert the master disk, and the 
game will automatically adjust to any 
Comspec device that happens to be 
present. This means that not only are 
hard disk drives supported, but also 
Bernoulli boxes as well as any other 
SCSI device. We are hoping to add 

other hard drives to our list of 
supported devices, but cannot do so 
without the help of the individual 
manufacturers. At dais time, only the 
Comspec SCSI controller is supported. 

Game Over 

When compared with other 
games available for the Amiga, and 
there are many fine entertainment 
products out diere, Don Biudi's 
Dragon's Lair is indeed a ground 
breaking product which may 
irreversibly affect the standards by 
which Amiga games are judged. With 
it's real time animation and sound, 
combined with it's exciting arcade 
gaming, Don Bluth's Dragon's Lair 
promises to be a big favorite for the 
foreseeable future. As Michael T. 
Cabral wrote in his AmiEXPO Midwest 
'88 report, "When you first see the 
graphics and animation, you'll take a 
look around to make sure you didn't 
somehow stumble into a video arcade." 

Versions of Don Bluth's Dragon's 
Lair are currendy under development 
for other popular personal computers, 
but very few of those machines appear 

to be capable of handling the enormous 

amount of work the Amiga must 
accomplish in order to achieve these 
spectacular results. Whether or not 
other versions are released will depend 
largely on the success of our 
programmers in pushing machines 
which were not designed for the task of 
animation to that lofty goal. With the 
Amiga setting the standard by which to 
measure our success on other machines, 
we can make no promises right now. 

On behalf of the whole Don Bluth's 
Dragon's Lair development team, we 
hope you enjoy this game. 

We would love io bear from any 
programmers or artists out there who 
would like to work on Amiga projects, or 
from those of you who have projects in 
mind you would like to see.

(EMPIRE, continuedfrompage41) 

Playing EMPIRE 

If you have ever played EMPIRE, 
you will have no trouble playing this 
version of the game. For the novice, 
ne\'er fear, the documentation is good 
and the menus are easy to use. 

There can be up to three forces 
\'ying for control of the planet. Any or all 
of the forces can be controlled by 
players or the computer. EMPIRE offer a 
play-by-mail option, but modem play is 
not available (yet). Each force has a 
different color, so they can be easily dis- 
tinguished. The playing ability of the 
computer can be changed as can the 
combat and production efficiencies of 
the game pieces. 

The world is usually divided up 
into several islands or conunents. Your 
map of the world is divided into a 60 x 
100 grid. To begin the game you are 
given a single city. Eventually you must 
produce an army from that citj' if you 
want to conquer another cit>'. Each unit 
(including cities) only knows about its 
immediate surroundings. Any area of the 
map that you ha\'e not yet visited will 
remain black until you move into that 
area. As your units move around, the 
map will be filled in with the information 
relayed from tliem. However, once your 
piece moves away from an area, the only 
thing that is certain is whether the area 
was land or sea. The enemy can and will 
be moving, just as you are. Opponents 
can only be seen while they are next to 
one of your units, but you will be able to 
tell where you last sighted them. 

To attack the enemy or a city, 
simply attempt to move your piece onto 
die occupied square. Then the battle 
begins. You never know who will be tlic 
victor of an engagement. It depends 
upon the fighting ability of your piece, 
the defensive ability of the opponent's, 
and a little luck. 

You control your pieces by giving 
diem "orders". Some pieces can be sent 
out on random, while any unit can be 
given a direct order as to move to an 
exact location or in a general direction. If 
a piece cannot follow its orders it will 
wait for you to help it out, but once you 
get die hang of giving orders this will 
seldom happen. Orders can be given to 
pieces via the keyboard, mouse, or 


One of the most impressive im- 
provements of this version of EMPIRE 
over all the others is the inclusion of 
sound. 1 could not belie^'e how much 
difference it made in the game. The 
armies' tanks rumble, the fighters buzz, 
and the ships swish (?). At first I thought 
the sounds would get old, but now I 
can't play witliout them. If you feel 
otherwise you can turn the sounds off. 
When you take weapons into battle, you 
hear tlie boom of large guns while the 
engaged pieces flash on the screen. 
When the guns go silent there will be 
only one survivor. 

The graphics are also an improve- 
ment over the previous versions of 
EMPIRE. As you might expect, land is 
green and water is blue. Unlike older 
versions of the game, the war units are 
no longer simple letters. An army looks 
like a tank when active and a row of 
tents when on sentry. Fighters naturally 
look like planes, and the ships ail have 
different designs. It is supposed to be 
possible to tell whether a troop transport 
or carrier has troops on board, but I 
found it fairly difficult. Aside from this 
short coming, I found the graphics 

Creating Worlds 

Finally I should note that you can 
create your own worlds to conquer. 
There is a map editor included with the 
game. A number of pre-designed maps 
are also included, so you won't have to 
produce a world right away. Once you 
have played with these worlds long 
enough, you may be able to start 
recognizing them. Unfortunately, the 
program only randomly selects a game 
map, it will not randomly generate one. 

Final Words 

The point of ElviPIRE is to be tlie 
sole survivor. It can only be accom- 
plished by careful planning. This version 
of EMPIRE is easy to play and hard to 
put down. Once you get your hands on 
this game you won't care about anything 
else. In fact, it was almost impossible to 
write this review, because it tore me 
away from my game.

up, and down the screen. The game 
will start with your ship at the bonom 
of the screen, and three tanks of 
energy (or lives) for shields. You will 
fmd your ship to be flying over a 
vertically-scrolling background which 
contain some of the best visual effects 
I have ever seen in a shoot'em-up. 

Aliens will enter the screen in many different attack formations, causing their defensive 
and offensive powers to be very strong. They will start at the top of the screen and 
slowly drop down to the bottom. As they are doing this, one of the aliens will go for 
what I call a "suicide dive" in which it will drop from the attack formation and go 
direcdy for your ship. Of course, while aU this is happening, they are firing a barrage of 
lasers aimed direcdy at you. 

You will find Better Dead Than Alien to contain a whopping 72 levels of play, 
each one with completely different aliens, attack formations, and backgrounds. As you 
progress from level to level, you wUl fmd each one more challenging than the last. I 
have been playing the game for about 30 to 35 hours, and I still have not made it past 
level 10. This is due to what they call the "bonus rounds". I call them the "freeway 
express rounds" because they require you to have the reflexes of a Sunday driver on a 
downtown expressway.

Bonus rounds? 

After you have managed to 
successfully destroy three waves of 
aliens, you wilt be presented with one of 
three different bonus rounds which are: 
Rocky Ride, Master Alien, and Super 
Alien. These have got to be the toughest 
bonus rounds I have ever seen for a 
game. They claim you can rack up some 
high scores here, I claim you can panic! 
The last two, Master Alien and Super 
Alien are just large aliens which are 
almost indestructible requiring you to 
have fast reflexes as you attempt to 
destroy them. However, the Rocky Ride 
is a different story all together. This 
round contains three very large boulder 
aliens with mean looking eyes that when 
hit split into smaller boulders. The best 
way to describe this is to think of the old 
Atari classic Asteroids, increase its speed 
by twenty times, and you have a good 
idea of what this bonus round is like. 
These are just a few of the bonus rounds 
you wUi encounter in the game, others 
await at higher levels to really challenge 
your reflexes. 

Don't fire until you see the 
greens of their eyes 

That's right, aliens don't have 
white eyes so you must fire when you 
see their green eyes. What does this 
mean? WeU, it certainly doesn't mean 
you're flirting with an outer space 
creature, but it does mean you've caught 
it at the weakest moment, When this 
happens, a power capsule will float 
down towards your ship for you to pick 
up by flying over it. The pane! icons are 

to the far right of the screen, and 
depending upon which one is lit up at 
the time you pick up the power capsule, 
an enhanced feature will be given to 
your ship. The laser scatter bolts allow 
your ship to fire multiple lasers, auto 
repeat saturation blasts will destroy 
multiple hit aliens with one shot, stun 
effect causes the aliens to freeze and 
stop movement, and clone ship doubles 
your ship (not lives) for added fire 
power. Others include multiple blast 
which fires a burst of missiles, armour 
missile takes out an entire rank of aliens, 
neutron bomb weakens all the aliens, 
and shield gives you limited protection 
from enemy fire. If one of the panel 
icons is not lit up at the time you pick up 
a power capsule, an extra energy tank 
wUl be given to you.

After playing the game for quite 
some time, I have found only one major 
complaint. That is, the inability to store 
the top ten scores to disk. If you get a 
really high score, you will be asked to 
enter your name, and when you stop 
playing the game you will lose your 
score forever. This hardly seems right, 
especially when you want to boast your 
score of over 500,000 to your friends. 
Hopefully Etectra will change this in a 
future version of the program. 

Better Dead Than Alien combines 
a great blend of arcade-action, superb 
graphics, and sound effects to make it 
the best shoot'em up I've seen. Due to 
the many levels of play and changing 
scenery, you will find it difficult to get 

bored with playing the game. If you like 
lots of arcade action where your fire 
button is used to squeeze off millions of 
shots, then this one is for you! 

Hints and Tips 

1. Never stay in one spot for 
more than several seconds. If you do, it 
will give the aliens an easy target for 
them to fire at and go for a suicide dive. 

2. Make sure and collect any 
power capsules that are available, for this 
is the key to making it out of really tight 
situations. If your timing is right, you can 
wait for the panel icon lights to go off 
before you have to shoot the alien with 
the green eyes. By doing this you will be 
given an extra energy tank ( or life). Be 
careful though, not reacting quick 
enough could result in no power capsule 
at all. 

3. When you encounter the 
Rocky Ride, use the following techniques 
for survival. You should concentrate on 
only one boulder alien at a time. Shoot 
this one first, then keep shooting the 
smaller boulders until it is gone. Repjeat 
this process until you've made it through 
the Rocky Ride.

48 Amazing Computing VS. 12 ©1988 



by Bruce Jordan 

Touted as the most popular video game in Japan, 
THEXDER is a futuristic, arcade-type game that actually 
lives up to every promise made on the outside of tlie box: 
action, adventure, fantastic sound, and stunning graphics. 
Written by talented 68000 machine language programmers, 
THEXDER turns out to be a real screamer, 

The Package 

The package consists of a single disk and a very 
brief set of instructions covering how to use the numeric 
pad as controls, how to use a joystick, the meaning of the 
status indicators that will appear at the bottom of the 
screen, and your objective; To penetrate all sbsteen levels 
of this heavily defended, erie underworld and destroy the 
central computer. To aid you in your mission, you've 
been given Thexder, a robot fighting machine complete 
■with lasers, and the capability of transforming itself into a 
jet fighter. Transformation is accomplished by pulling 
down on the joystick or by pressing any of the bottom 
three numeric keys. However, you're warned that there's 
only one Thexder, and death on any level sends you right 
back to level one. 

Ingeniously, when the instructions are unfolded, they form a wall-sized map of 
the first level of play, giving directions and a few hints. Around the border of the map 
are pictured some of the intriguing nasties you'll be facing. Some twenty in all are 
displayed, but there's a heck of a lot more than just these lurking out there. 

Plug in tbatjoystickf 

On booting the copy protected disk, up 
comes a quick title slide displaying an alien 
landscape and the digitized voice of some young 
woman saying in Japanese, "Sierra On-line 
presents THEXDER". Next comes the main title 
slide, listing copyrights and credits, while in the 
background plays the Moonlight Sonata by 
Ludwig van Beethoven. The game begins as 
soon as any key is pressed. Pressing the "J" key 
sends control to the joystick. If you have a 
joystick, I strongly suggest you use it! 

When play starts, you find yourself literally 
up against a wall as the instructions warn, "There 
is no turning back!". Suddenly, you hear the 
same woman's voice proclaim, "Warning! 
Intruder!". There's nothing to do but turn, try to 
stay alive for as long as possible, and find you're 
way to the next level. The battle is on! Almost 
instantly you find yourself fighting off an army of 
the most imaginative and interesting criners to 
come along in quite a while. You'll face Tribars, 
Blademills, Rimquarts, and Clobters to name just

Virus Infection Protection (V.I.P) 
from Discovery Software takes tlie first 
step in helping you protect your 
valuable software from the deadly 
disease. By acknowledging that this 
exists in the Amiga community, we are 
providing end users with not only 
information, but also a solution to the 
problem. Before we move on, let's 
further explore what exactly a 
computer virus is. 

What makes a 
computer sick? 

Did you know that your 
computer can catch a deadly and 
harmful disease? Well, while it might 
not be like you and me catching a virus 
it can certainly cause the computer to 
reaa violently. What I mean by this is 
that it can destroy your precious 
computer disks, any and all without 
discriminating, A virus will get inside 
your computer's RAM memory residing 
there until the computer is turned off. 

While it's present, any disk that is 
inserted in the computer can be infected. 
However, this is only true for disks that 
are autobooting (i.e. Workbench, games, 
etc.). The way the virus gets from the 
computer's RAM to disk is that the virus 
itself will be copied onto the vital boot 
block sector, without which your disk 
will not function. When we are referring 
to a virus in essence we mean an "evil"

computer program written by people 
wishing to derive pleasure from knowing 
that they've destroyed someone's 
valuable software. What is worse is that 

it's not just the Amiga community either, 
but rather all computer companies are 
finding themselves confronted with the 
same bad situations. For more 
information on computer viruses you 
should locate a copy of Time Magazine 
September 26, 1988 issue. Now that 
we've briefly discussed computer 
viruses, let's introduce the vaccination. 

Ttje cure for sick software 

Virus Infection Protection will 
restore your damaged software to its 
original state by destroying any virus 
which is on the disk. Once the program 
is loaded, you will find five pull down 
menus which are: project, check, 
language, file, and viff entry. The project 
menu has four items on it which cell 
about the product, a brief description of 
the concept behind it, help witli all the 
menu items, and quitting the program. 
On the check menu you'U find three 
items which are; examine, classify, and 

The examine option allows you to 
insert a disk into any disk drive and 
check it for a possible virus. You will be 
happy to know that V.I.P. cunently 
supports six of the most widely known 
and dangerous viruses which are: SCA, 
Byte Bandit, Byte Warrior, Obelisk, 
North Star, and Revenge. If your disk 

Checking for a rArus tvith VJP 

50 Amazing Computing V3. 12 ©1988 

contains a virus, a window will appear 
saying so along with the name of tiie 
virus which was found. The classify 
command allows you to enter new virus 
information into the database. 

If you discover a disk to contain a 
virus which V.I.P. will not recognize, 
then you may select this command 
which will store the information so that 
from that point on it will know when it's 
encountered. Whenever one of your 
disks becomes infected witli a virus, and 
it's standard AmigaDOS boot code, then 
you may use the install command to 
correct it. 

The file menu has six items on it 
which are: new, load, save, save as, 
delete, and print. "When first starting out, 
you should select the new option which 
will create a viff file. What this file will 
contain is all the boot blocks from the 
disks you wish to store, and can be 
given any name (i.e. If you want to store 
boot blocks for games, simply name the 
file games.) The viff file must be stored 
on an already formatted disk, don't use 
the V.I.P. disk for storage. The load 
option allows you to work with an 
already existing viff file, which may 
either be empty or contain boot blocks. 
Other options are self explanatory so I 
won't botlier to describe them. 

The viff entry menu contains 
seven items which are: view, make, 
remove, sort, verify, write, and print. You 
may view the boot code of any viff entry 
by selecting this option from the menu. 
The make command allows you to create 
a boot block from the disk of your 
choice to be stored in the viff database. 
For example, if you've checked Arkanoid 
for a virus and found nothing then you 
may wish to back it up in case disaster 
strikes. To do this, you simply insert 
Arkanoid into a disk drive and select 
make which will read the boot block so 
that it may be stored and recalled later. 

The remove item allows you to 
delete any boot block which is stored in 
the viff database. 

Sort allows you to organize your 
boot blocks according to date, 
alphabetically, date disk was created, and 
ID number. 

The verify command allows you 
to compare die boot block in the viff 
database to the one which is on the disk. 

If your disk gets a virus, you may 
destroy it providing you've already 
stored tliat boot block in die viff 
database. Using the write command 
allows you to select the appropriate boot 
block which will destroy any virus on the 
infected disk (i.e. If Arkanoid gets 
infected, select the Arkanoid boot block.) 
The print command allows you to get a 
hard copy of the actual data contained in 
a viff entry. 


What makes V.I.P. so simple is its 
easy to use operating environment. AH 
the user has to do is follow the manual 
and on screen instructions, which are 
designed very nicely. I think it's time that 
we all stood up and said, "Enough is 
enough and we're not going to take any 
more of tliis kind of abuse from people 
wanting to destroy the Amiga 
community!". That's just what I feel 
Discovery Software did by publishing 
such a valuable product as Virus 
Infection Protection. I commend them for 
keeping software users in mind, and for 
taking that first gigantic step in 
preventing valuable data loss. 

I've been told that as more strings 
of viruses are found, tliey will keep 
updating V.I.P. to vaccinate diem. In my 
opinion V.I.P. should stand for Very 
Important Product, which is exacdy what 
it is and no user should be without one!

a few. Each is animated and has its own 
unique personality. Of course, lliere's the 
odd lava pit and acid lake to watch out 
for as well. 

If you have time to look at the 
bottom of the screen, you'll see 
displayed your score, your energy level, 
the level of play you're currently on, and 
your Enmax: the highest amount of 
energy you're allowed to possess. 
There's also an indicator for shields 
status. Shields are activated by pressing 
the left Shift key on the Amiga keyboard, 
and can be a real lifesaver. However, try 
to use them sparingly. Activating your 
shields takes ten energy points, and 
completing a level of play without 
shields is rewarded by extra energy. 

As you frantically scurry and fly 
through mazes, vast cargo bays, and 
caverns, you run into wave after wave of 
attackers, sometimes twenty and thirty at 
time. However, it doesn't take long to 
discover that the bad guys can be broken 
down into three groups: (1) Actively 
hostile: those determined to kick your 
metallic backside no matter what, (2) 
Passively hostile: these aa as barriers 

and will not attack, but on contact will 
suck your energy dry in seconds, and (3) 
Semi-hostile: non-attacking, but again, 
lethal to the touch. However, destroying 
any of the third category of creamres 
gives you energy. Finding and destroying 
this third type of creature is essential for 
staying alive, as energy is the name of 
the game. Many of these energy* 
creatures are cleverly hidden in the walls 
and must be blasted out. Fortunately, in 
robot mode, your lasers are heat seeking, 
and if your beams are suddenly aitraaed 
to a wall, it's a good bet that there's 
someone hiding there. Alternately, in 
fighter mode, your laser fire is always 
directed straight ahead, and with no heat 
seeking ability. So if you're getting low 
on energy, try to stay in robot mode as 
much as possible. 

More than just your average 
shoot-'em-up, THEXDER has an added 
dimension. Many of the situations you 
find yourself in are actually clever, logic 
puzzles, where the solutions may consist 
of finding ways of getting free energy, or 
suckering out the nasties by some special 
means. This helps keep repeated play 
from becoming boring, and motivates 
you to try a new strategy on the thing 

that wasted you the last time out. Ai the 
same time, THEXDER is so rich in 
complex, little details that you're almost 
guaranteed to notice something new 
each time you play. Praises go to the 
authors, S. Uesaka and G. Godai! 


As for the overall game; as a 
"quarter saver", I found it flawless. It's 
visually stunning, the animation is as 
smooth as silk, all of the creatures are 
interesting and clever, and the forbidden 
underworld is exceedingly intricate and 
full of surprises. Obviously written for l6 
bit machines, this game does real justice 
to the capabilities of your Amiga. If you 
like action/arcade games, THEXDER is 
defmitely worth the money. Check it out, 
and I'll see you on level eight.

/The statements and projections 
presented in "Roomers" are rumors in the 
purest sense. The bits of information are 
gathered by a third party source from 
tvhispers inside the industry. At press 
time, they remain unconfirmed and are 
printed for entertainment value only. 
Accordingly, the staff and associates of 
Amazing Computing™ cannot be held 
responsible for the reports made in this 

Aegis is looking hale and hearty 
these days, thanks to a healtJiy infusion 
of capital (more than a million, it's said). 
Their booth at AmiEXPO was impressive, 
displaying their new confidence. The 
word is d:at their cash flow cri.sis is 
solved, new people are being hired to 
replace the old guard that left, and 
product development is proceeding 
apace. See how rapidly things can 
change in this business? It [ust goes to 
show you. (Remember what Mark Twain 
said about his premature obituary?) 

Aegis's new Audiomaster 11 
sound editing program iooks like a 
winner: it turns your Amiga into an 
oscilloscope and gives you real-time 
effects like echoing — speak into the mike 
and your voice is processed dirough the 
Amiga in real time. Very impressive. 
Aegis also announced a new program 
called Videola — designed for editing 
ANIM files; and a new version of Sonix 
that offers more editing features and full 
MIDI compatibility. 

Also at AmiEXPO, Allen Hasting's 
new mini-movie Rush Hour was a hit, 
drawing crowds at every showing at the 
NewTek booth. No new movies for a 
while, since he's at work programming 
on a top secret project with NewTek. 
(The Bandito's informant proved 
extraordinarily fragile during routine 
questioning, so no details yet. They just 
don't make informants like they used to.) 

Possibly the strangest thing at 
AmiEXPO was the lack of new products, 
Oh, there were plenty of games, and 
some new versions of old products were 
announced or hinted at, but nothing to 
make you jump up and run down to 
your local Amiga dealer. Most companies 
were showing the same old things in the 
same old way. Seems like the turmoil at 
many Amiga developers has slowed 
down product development a bit, and 
most developers are putting their effort 
into marketing their current product for 
Christmas rather than introducing new 
product. Look for a slew of new product 
introductions in the first quarter of next 
year, including some long-awaited 
hardware and software. 

AmiEXPO also had smaller crowds 
than expected. The problem could be 
related to tiie prices: $20 for one day 
admission, $15 to park at the hotel 
parking lot, plus the aggravation of 
having to deal with LA traffic (which is 
abysmal even on the weekends). So 
throw in a little bit of money for food, 
and you're talking about nearly fifty 
clams just to pick up a bagful of flyers 
and see a Madonna imitator. Some 
developers were grumbling that it's not 
worth it unless there's a better turnout, 
It will be interesting to see how this 
compares to the upcoming World of 
Commodore show in Philadelphia. 

Is Mediagenic (actually, their 
Activision division) negotiating to buy 
one of their affiliated labels that's made a 
name for itself in the Amiga market? 
Well, it certainly sounds like a good 
match-up. Stay tuned to this space for 
more information. 

The Bandito mentioned Dragon 's 
Zair before, and here's an update. The 
game comes on sis disks, retails for $60, 
and they're distributing a demo that has 
about six to ten seconds of really superb 
video on one disk. But cynical observers 

note that the original game had about 20 
minutes of video, Sbc disks at 10 seconds 
per disk yields about 1 minute of game. 
Either they've got some incredible 
compression, or the whole game doesn't 
look quite like the demo we've seen. 
What will the game really be like? 

New Technologies Department: A 
new CD format has been created — 
CD+MIDI, which stores up to 16 
channels of MiDI data (along with 
graphics) in the subcode area of the disc. 
Making a CD player compatible with CD- 
MIDI adds about $2 to the manufacturing 
cost, so expect to see a number of the 
new players with this capability. CD- 
MIDI lets you relocate instruments or 
voices in die playback mix, change the 
sound of the arrangements by revoicing 
parts with your own MIDI equipment, 
and change the tempo or key. You can 
even print out sheet music, resequence, 
or repeat sections if you've got a 
computer hooked up. Makes an interest- 
ing addition to an Amiga music studio. 

In other news, an interesting 
conference on computer game design 
just took place in California. It was 
described by attendees as similar to 
Electronic Arts' Artist Conference, only 
independent of any software developer. 
It was put on by Chris Crawford, the 
grand old man (or enfant terrible, 
dep>ending on your point of view) of 
computer game design. There were 
seminars for game design, technical 
issues, and legal stuff to do with com- 
puter games. Mainly, of course, people 
were cutting deals in the hallways and 
exchanging juicy gossip. 

The Amiga seems to be com- 
manding more respect as a target 
machine for games that can make money 
and generate great PR value, though the

hatred for the marketing people at 
almost every publisher, regaling each 
other with stories of the ignorance and 
cupidity of market-droids. According to 
the developers, it seems that many of the 
marketing people at the biggest publish- 
ers come from strange backgrounds, like 
selling dog food, shampoo or fertilizer. 
Many of tliese market-droids are not only 
ignorant of computers and games, but 
tliey don't WANT to leam anything, 
which is really annoying. At least tlie 
smaller publishers don't have the 
problem (well, maybe not lo the same 

Lotus is planning to do 1-2-3 for 
the Macintosh, IBM mainframes, and 
other odd Vfpes of computers. Could 
they be looking at WordPerfect's success, 
and seriously considering an Amiga 
versioa' The market's getting big 
enough. If they aren't, they should be. 

Commodore is spreading its 
advertising dollars a little further afield 
these days. New ads, appealing to the 
professional graphic artist, are appearing 
in Advertising Age and Print magazines. 
There's a very nice Amiga ad in Mix 
magazine, the recording industry' rag. It's 
a tw^o page spread with ver^' slick 
graphics and text. It looks like Commo- 
dore is getting serious about going after 
the music market. They're signing up 
many music dealers, especially targeting 
the ones that Atari acquired during their 
big push into the music market. Unfortu- 
nately for Atari, their success has paved 
the way for Commodore to do the same 

Overall, Commodore's doing 
great, showing better profit numbers 
every quarter. The Amiga is accounting 
for a bigger percentage of their sales 
with each passing quarter, which is just 
fine since it's the most profitable of all 
the computers they sell (the A2CX)0 is 
especially profitable). Commodore's great 
fear, that C64 sales would collapse 
before the Amiga has a chance to pick 
up the slack, has proven unfounded as 
yet. Wliile C64 sales continue to slow, 
there's no sign of the bottom falling out 
of the market. Commodore's busy 
picking up new retail accounts for the 
Amiga: Computerland will carry the 
A2000 in .some stores; Entre computers 
carries it; and Fry's, the hacker's com- 
puter store in Silicon Valley, has dumped 
the Atari ST and is carrying the Amiga. 

The A500 is developing as the 
premier game machine, and that's what's 
driving sales. The A2000 has a tougher 

road to travel. It needs somediing to 
really break into the business market, 
something like the LaserWriter/Page- 
Maker combination that made tlie 
Macintosh sell. The Bandito thinks the 
answer lies somewhere in tlie desktop 
video market... 

Look for some good deals on 
Amiga 2000s this Christmas. The price 
may not be lower, but dealers will 
probably bundle software and hardware. 
This is a result of Commodore giving 
them better profit margins in an attempt 
to boost A2000 sales. Don't look for any 
price decreases for the foreseeable 
future; Commodore will likely use 
rebates, bundling, or otlier promotions 
rather than reduce the list price. 

There's a new problem for Amiga 
dealers — finding shelf space for all of 
the Amiga software titles. Many dealers 
are having to rearrange their shelves, or 
at least tliink more about what to stock. 
At last count there were about 500 
different Amiga titles available (about 
half of them are games). This portends 
some big changes in the Amiga software 
market. Gone are the days when any 
software title could find a spot on the 
shelf. It's becoming dog-eat-dog out 
there, and the days of the ziploc bag, 
software are just about over. With every 
passing day, tlie cost of bringing a piece 
of Amiga software to market (witli 
distribution, packaging, and advertising) 
increases. Which probably means we'll 
see a little less innovation (.sigh) as the 
products are brought out by larger and 
larger companies. 

Don't be surprised you see one or 
two major Amiga developers pulling 
back on [lieir advertising. There's a little 
bit of the cash-flow flu going around, 
and some developers have a bad case. 
Not to wony, they'll feel better after 
Christmas, when Santa brings them 
hearty sales figures for their stocking. 

The ST is fading fast — develop- 
ers no longer even discuss doing a 
version of a successful IBM or Amiga 
product for the ST, since there's no 
money in it. So many of the staunch 
Atari developers are looking other places 
for revenue. Some are trying to aack the 
IBM market, and others are trying to take 
their 68000 expertise to the Macintosh 
and Amiga markets. Antic, one of die 
ST's most fervent supporters and a long- 
time Amiga-basher — look at some back 
issues of tlie magazine — has now 
deciphered the text font on the wall and 

started Amiga software development. 
They annoimced that Zoelrope, Jim 
Kent's animation program for the Amiga, 
will be available soon. They're also 
selling Pioneer Plague, billed as tlie first 
all HAM mode action game. They're very 
careful not to mention the word '"Atari" 
when the)' talk to Amiga fans... 

David Klein, Electronic Arts' 
superstar salesman, has left to become 
Commodore's new Vice-President of 
Marketing. Those in the know say that 
he should do a whiz-bang job. Look for 
some new and different approaches to 
Commodore's marketing and distribution 
next year. By the way, Klein's sfjecialty 
at EA was selling to mass-market 
accounts like Toys R Us. 

Deep C, the Bandito's Commo- 
dore connection, reports several interest- 
ing developmenLs in the Commodore 
laboratories. The first one is a better 
blitter chip, more than twice as fast as 
the current model. And of course diey're 
working on 15-bit color (that's a palette 
of 32,000 instead of 4,096), witii a new 
HAM mode diat allows all of those colors 
to be displayed at once. (This ties in with 
something the Bandito heard elsewhere, 
about a developer who's working on 
applications that work in many more 
than 4096 colors on tlie Amiga.) 

But the hottest idea being bandied 
about at Commodore is this; take an 
Amiga 500, remove some of the unneces- 
sary stuff like die keyboard, the disk 
drive, the mouse, and most of the ports, 
put in a cartridge port, and what do you 
have? A Nintendo-Killer, if you can price 
it around $200. That's right, Commodore 
is thinking about taking a shot at the 
videogame market. The big discussion 
centers around liow much memory to 
build in — some reactionaries are 
arguing for 256K, but tlie progressives 
want 1 megabyte. Bet on at least 512K so 
they can run the majority' of current 
Amiga games. If this happens, there'll be 
a tremendous oppominity to make 
money from the current crop of Amiga 
games, so you can bet that developers 
are watching with great interest. 

■Wliile we're on the subject of 
videogames, let's talk a bit more about 
CD-I. Adding to the confusion surround- 
ing this new hardware is RCA's Digital 
Video Interactive (DV-I), which is similar 
to CD-I except tliat it offers full-screen, 
full-motion video (by using some sneak>' 
compression tecliniques). RCA initially 
demoed DV-1 at a CD-ROM conference 
and completely upstaged CD-I. After- 

54 Amazing Computing V3. 12 ©1988 

wards, RCA said that they were just 
presenting the technology' and didn't 
know what kind of product it -would 
make. The consensus at that time was 
that DV-I would be just a high-end 
business hardware option, since RCA's 
first guess was that a DV-I board for a PC 
AT computer would cost about $3000, 
putting it well out of reach for any but 
the most esoteric applications. But now 
Intel (makers of the 80x86 chips) has just 
bought the rights to the DV-r chip set 
and the technology, so we could see DV- 
I as a consumer device after all. Or 
p>erhaps as a computer industry standard, 
extending the CD-ROM format. But don't 
expect anything until the 1990's. 

There's a flood of games coming 
from overseas, and the Bandito has 
noticed that each has its own distinctive 
packaging — from CD jewel boxes to 
albums to boxes to baggies. Some of the 
"artwork" (to use the term loosely) 
would gag a maggot. (But then, a few 
packages from our side of the Big Ditch 
look like old road kills, themselves.) 
While the graphics and sound are usually 
pretty good, most of the imports are 
lacking when it comes to game design. 
The Bandito wishes there was somebody 
reliable out there who could review ALL 
of them as they come out, so that people 
wouldn't waste $30 on trashy games (and 
add to the trade deficit, besides). 

Yet another flight simulator, 
Skychase, is coming out, and this one 
boasts the fastest frame rate of any 
flightsim on die market (it's wire-frame 
instead of filled solids). You can fly all 
sorts of planes, even a paper one, in 
head to head competidon with another 
player or the computer. 

Dale Luck (one of the original 
Amiga development team who's still 
hanging in there at Amiga Los Gatos) has 
developed a three-bunon optical mouse 
for die Amiga. It's pan of his X- Windows 
development effort; on sale in January, 
or thereabouts. The mouse is twice as 
accurate as the ordinary mouse, and less 
prone to mechanical trouble. 

New Hardware Dept.: The NeXT 
computer was introduced October 12 to 
great hullabaloo. It does have some neat 
gimmicks (a 256 megabyte erasable 
optical disk, for one), but it won't even 
be available in quantity until the middle 
of next year, and then only to universi- 
ties (and at a hefty S650O price tag for a 
monochrome machine). Of course, 
they'll probably start selling it to every-

body in 1990, but by that time the Amiga 
will have much of NeXT's capability... 
won't IL' Hello, Commodore? 

Speaking Of Other Guy's Hard- 
ware Dept.; According to inside sources 
at Apple, IIGS sales are disappointing, 
and the recent price hike won't help 
matters any. Apple seems to think the 
Amiga is one reason — which may be 
why dealers are reportedly being 
pressured NOT carry Amigas if they carry 
Apple products. And don't look for the 
IIGS Plus real soon; it now looks like 
they won't bring it out until the summer- 
time, or maybe even the fall. They're 
busy concentrating on Macintosh sales. 

One thing to keep your eye on — 
will Apple drop the Mac Plus from the 
product line, or drop the price and keep 
it around? Things would be easier for the 
Amiga if it didn't have to compete with a 
$995 Macintosh. Sure, technologically it's 
not much of a contest, but remember 
Apple's marketing muscle. Let's hope the 
plug gets pulled on the Mac Plus. 

There is no truth whatsoever to 
the rumor that a major Amiga developer 
is porting its animation software to the 
Etch-A-Sketch, even if die interfaces are 

More Amigas in the media; they're 
in the John Carpenter film Prince of 
Darkness (even using Amiga text fonts 
and wire-frame animation); they're 
generating some of the graphics for the 
Max Headroom Coke commercials; 
they're being used by the good guys in 
the newWarofthe WorldsTV series; 
they're helping out with the production 
of Who Framed Roger Rabbit. A few 
more liit films, and maybe we'll see good 
ol' Ami written up in Hollywood gossip 
columns; "Ami was seen out on the town 
partying hearty with Ashton Tate, 
spuming her recent boyfriend Mike O. 
Soft..." From there, it's only a short step 
to the Betty Ford Clinic to deDOSify...

The Command Line 

Although AmigaDOS is a powerful operating system with 
some very useful commands and a fair amount of flexibility, the 
creators left a few things out. Fortunately, the Amiga has 
attracted a lot of attention from top notch programmers that 
have helped to fill in these gaps. These developers occasionally 
write small programs to ftll a specific need diat arises during 
program development. To our great fortune, many place the 
utility program in the Public Domain. 

These programs are free for the downloading or copying 
time you wish to invest. Some of the authors request a modest 
donation if you tike the program and use it. Others are 
classified as "Shareware" meaning that the program is free for 
you to use to determine if it fills your need. If you use it, you 
are asked to send a payment to the author ranging from SIO to 
S25. Quite reasonable. Particularly if you consider that many of 
tiie programmers will reciprocate by sending you the latest 
version of die program, complete documentation, and often, 
additional sample programs of other utilities offered. 

AmigaDOS don tfail me now! 

When tlie commands of AmigaDOS fail us, we can often 
turn to the wide range of "freely distributable programs" that 
exist in numerous User Groups and on hundreds of Bulletin 
Board Systems throughout the country. In the next few issues, I 
will examine some of the programs that have been written to 
address several weak spots in AmigaDOS. If you already own a 
modem, you have at your disposal a door to a fantastic worid 
offering something for everyone. If you don't own a modem, I 
strongly urge you to put one on your list of "Toys I MUST 

User Groups 

A User Group is the next best thing. You will find 
people of varying ages and backgrounds with a dedication to 
your favorite machine that could be classified as "fanatical". Ask 
some of the "Old Timers" what utility' programs diey find most 
useful. There are hundreds of tides in the Public Domain and 
finding just the right program to fit your needs can often be dis- 
couraging. The list provided at the end of this magazine. The 
AMICUS & Fred Fish Public Domain Software Library, is a re- 
source of unparalled distinction. Use it. 


The line editor used in the console windows must have 
been written in the dark ages. It's a real pain to retype an 
entire line that is rejected because of a typographical error. 
Several solutions to this problem were introduced early on with 
each having various inconsistencies of their own. Then along 
comes William Hawes with ConMan and the sun begins to 

The keyboard communicates to the Amiga through a 
type of driver that interprets the key codes and displays the 
results. The one supplied by Commodore has a single distin- 
guishing editing feature: the BACKSPACE key. How can you 
build the greatest computer of the decade and then curse it with 
a keyboard interface seemingly derived from the Teletype? We 
may never know. ConMan up-roots the default console handler 
and replaces it with one that provides powerful editing capabili- 
ties. Once ConMan is installed, every console window opened 
will use the new console handler. So what does ConMan do? 

A. Editing 

1 . Complete editing facilities using the Left and Right 
cursor keys. 

2. The DELETE key works as it should. Delete words 
backward (F7) and forward CF8). Delete from tlie cursor to the 
end of die line (Control Y) or to die start of die line (Control U) 
or delete die entire line (Control X). Delete all lines, including 
type ahead lines (Control 2) or return diem (Control R). 

3- Skip to next word backwards (Shift Left Arrow) and 
forward (Shift Right Arrow). 

4. Toggle between Insert and Overstrike (Control A) 
or force Insert mode (Control a). 

5. Support of Xon (Control S) and Xoff (Control Q). 

B. Command History 

1. Recall previously entered lines by pressing the Up or 
Down Arrow keys, Shifting each of diese will recall ilie latest 
and oldest lines respectively, 

2. Clear the history buffer widi Control B. 

3. Buffer size and recall mode options diat may be set 
when ConMan is first started. This affects all console windows. 
If you need to change these later, the utility program SetCMan 
makes it easy. The default buffer size is large enough to hold 
25 to 30 lines.

Tliie Super-speed, DMA, SCSI Hard 
E>i3k Interfece with 1 .3 Autobootirig 

8-UP! The eght Megabyte 
Memory Card with Amiga-specific 
DRAM Controller Logic 

How fast is fast? HardFrame/2000 transfers data 
at Amiga bus speeds! It's actually faster thar^ the 
hai'd disk mechanism, itself! And even more important 
in the Amiga's multitasking environment, HardFrame/2000 has 
extremely efficient DMA circuitry to get on and off the bus in al- 
most no time at all: 280ns to get on; 200ns to get off. HardFrame/ 
2000 autoboots under AmigaDOS'"'''' 1.3 and is fully compatible 
with the new Fast File System. The core of any DMA SCSI inter- 
face is its SCSI protocol chip and DMA chip. MicroBotics has 
chosen the new, high performance Adaptec AIC-6250 SCSI chip, 
capable of up to 5 megabytes per second raw transfer speed, and 
the Signetics 68430 DMA chip running at 12.5 megahertz. Then 
we added additional FIFO buffering and enabled 16-bit wide 
data transfers for maximum throughput. The sophisticated de- 
sign of HardFraine/2000 provides for automatic SCSI arbitration, 
selection and reselection. The hardware supports either syn- 
chronous or asynchronous data transfer. HardFrame/2000 can 
function as either the SCSI bus initiator or the target and can re- 
side in a multiple master environment. Physically, HardFrame/ 
2000 is optimally flexible: the compact, half-size card comes at- 
tached to a full length, plated aluminum frame. The frame has 
mounting holes positioned to accept standard, 3.5" SCSI hard 
disk units such as those manufactured by MiniScribe, Seagate, 
Roc'.ime, and others (hard disk mechanisms must be supplied by 
the user or his dealer as a separate purchase item). Alternatively, 
you can cable-connect to a SCSI drive mounted in your Amiga's 
disk bay or in an external chassis. As many as seven hard disks 
may be connected to a single HardFrame. There is no size limit 
on each disk. HardFrame/2000 includes a 50-pir. SCSI cable and 
header connectors for either 50-pin or 25-pin cable connection. 
Also included is a current tap to power frame-mounted drives di- 
rectly from the slot itself. HardFrame/2000 comes complete with 
driver, installation, and diagnostic software. Available September 1988. 
Sug^;e&ted list price, £329 (hard disk not included). 

All the memory space you and your Amiga 2000 
need -in a modern, highly integrated FastRAM 

expansion board, in 8-UP!, MicroBotics went all the way to 
provide you with a truly Amiga-specific memory design to meet 
the special demands of the Amiga's high speed multitasking en- 
vironment: The heart of any memory expansion is its DRAM con- 
troller circuitry. Rather than compromising with off-the-shelf 
parts, MicroBotics developed its own, custom controller design 
and built it into high-speed. Programmable Macro Logic chips (Sig- 
netics PLHS501). These new, super chips (each 8-UP! uses two 
PML's) permit MicroBotics to employ sparse refresh technology to 
assure that your 8-UP! is a truly zero wait-state/minimal-refresh- 
collision memory design. If you're putting eight megabytes in 
only one slot, that means that you probably have plans for your 
other A2000 slots. 8-UP! gives you new freedom to do that plan- 
ning since, unlike other ram peripherals, it is an extremely low- 
power memory card- a single, fully-loaded, 8-megabyte 8-UP! 
draws an astoundingly efficient 0800 milliamps! That's less than 
two-fifths of the power "budget" for a single slot! Low power draw 
also means that the card is cool-running for reliability and long 
life (not to mention a cooler Amiga!). 8-UP! offers you maximum 
flexibility in memory configuration: it is organized into two sep- 
arate PIC's (Amiga-speak for autoconfiguring peripherals). Each 
8-UP! PIC consists of four SIMM module sockets; these sockets 
accept either 256k-byte or 1 megabyte SIMM's (Single Inline 
Memory Modules). You can also purchase optional PopSIMM 
boards from MicroBotics; fill thenn with conventional RAM ; then 
use PopSIMM's to fill your 8-UP! The card can run with as little 
as 512k of memory or as much as eight megs -with many inter- 
mediate configurations possible (particularly the six megabyte 
configuration, most desirable for use with a BridgeCard '''"). 8-UP! 
is speedy, efficient, custom memory technology for your Amiga 
2000 -and it's available now! 8-UP! suggested list price is $199 (Ok installed). 
Optional PopSIMM's are $49.95 per pair.

product with a MiniScribe 20 megabyte 
hard disk installed. Hard disks are not 
included in the purchase price of Hard-

4. Search the buffer forward (F6) or backward (F5) for 
a match on a partial string. 

5. If you've entered a long line and accidentally hit 
the up or do'wn cursor keys (thereby recalling a previous line), 
you can get it back with Control - (minus). 

C. Window Manipulation 

1. Shrink (Fl) or expand (F2) the console window. 

2. Pop the window (FIO) or tlie screen (F9) to the 
back or to the front. 

3. New window attribute options for including or 
excluding the gadgets and other features. (Very Nice!) 

4. Clear the window with Control W. 

Included with all of this is several utility programs for 
manipulating the command buffer in various ways. THIS is the 
type of console the Amiga should have had to begin with. 
Once installed, ConMan is transparent to the user. Each 
NEWCU command will automatically engage the mastery of 
ConMan when the window is opened. I commend Mr. Hawes 
for his fme effort to bring this most welcome addition to the 
Amiga. He has also written a program he calls WShell which I 
■will be using soon. I will cover WShell, Matt DUlon's Shell and, 
if available by then, AmigaShell (WB 1.3) in a future issue. A 
Sheil is a command environment with some spiecial features to 
make CLI operations much easier. This should not be confused 
with console handling software such as ConMan which gives 
you a better ANSI Terminal. 

All of the escape sequences described in the last issue 
are still accessible and I've found ConMan to be compatible 
with everything I use. The latest version of ConMan may be 
found on Fred Fish Disk i!^133 or you can order it direcdy from 
the author -

I stumbled across an interesting window manipulation 
feature using the Fl and F2 keys as described above. If you 
create a window -with NEWCLI that is some portion smaller than 
the full screen, the F2 key may be used to increase the window 
size to full screen while the Fl key will collapse the window. 
Try this: 

1 > NEWCU CON:0/200/640/200/Neato 

Now press F2. The window opens to full screen. Press 
Fl and it collapses into a small window at die top left comer. 
Press Fl to open it to full screen again. Press F2 and the 
window returns to the original size when opened. Press Fl and 
it will collapse and stay in the middle of the screen. VChat's so 
great about this? If you want a smaller window but need a full 
screen display once in a while, you don't need to have several 

console windows hanging around. Mr. Hawes indicates that the 
next release will include "an improved iconify state" which I 
hope will work similar to the next program described. 


Wouldn't it be nice if you could click on a gadget or 
something and cause a console window to get out of the way? 
We're all used to Icons. VPhy not provide a way to make a 
window disappear and leave an Icon behind to let you pop it 
back to full size when needed? Davide P. Cervone apparendy 
feit that tills would be a nice feature and wrote wiconifj' to 
solve the problem. Great job Davide! Several attempts have 
been made to get the window out of the way, from TinyWin- 
dows to Smartlcon. I feel wiconify provides the most elegant 
solution. Once installed, neariy any window on the Workbench 
screen will Iconify, even some commercial program windows. 
Because the program operates on the Workbench screen, you 
must run LoadWB before wiconify is started. To collapse a 
window press and hold tlie left mouse button then tap the right 
mouse button. 

Although this works well enough, I think it might be 
better to provide a new window gadget instead. When col- 
lapsed, a small icon resembling a console window appears near 
the bottom of the Workbench screen with the tide of the 
window underneath it. You can manipulate it the same way 
you would a Disk icon. New menu items are added to the 
Workbench menu for manipulating the icons. Below the DIS- 
CARD item on the WORKBENCH pop-down menu you should 
fmd an ICONIFY item which produces VERSION, CLEANUP, 
will neady arrange multiple icons similar to the Clean Up selec- 
tion on the SPECIAL pop-down menu. OPEN ALL v^'ill cause all 
iconified windows lo open back up, END terminates wiconify 
and VEPtSION displays information about the program. You 
may also use die OPEN and CLOSE items from the WORK- 
BENCH pop-down menu as you would with other Workbench 

Although Davide warns that he cheats some to make the 
program work and that it may not be compatible with a newer 
release of Workbench, my spies tell me that only the menu 
items seem to be inoperative with AmigaDOS 1.3- 


One of the problems we ran into whQe writing batch files 
was in determining what volumes are mounted without causing 
that blasted requestor to pop up. Bryce Nesbitt gives us a 
program called MOUNTED that eliminates the problem. 
MOUNTED will test for the presence of the volume specified in 
the command string and return a value that may be used by the 
IF command. The format is; 

MOUNTED <volume;> 

(command to execute If the volume Is present)

If the volume Paint: is not present, nothing happens. No 
requestor pops up and the batch file continues on. If it is 
present, then we test for the data disk. If the data disk is 
present then make some assignments and finish up by running 
the paint program. You can see another problem right away. 
What if you forgot to put the data disk in the drive? No 
assignments are made but the paint program is still started. 
How can we improve this? Read on. You will find MOUNTED 
on Fred Fish Disk #79- 

Now, if the the data disk is not mounted we ask the user 
what to do. If the WABN string is entered (C) the WARN 
condition is set to true and the file is executed again from the 
top. (This makes sure that the volume WAS mounted by testing 
again.) If the OK string is entered (A), the TIMEOUT value 
expires, or the RETURN key is pressed, the ELSE section is 
executed and it skips to the bottom. If something other than 
the WARN or OK strings is entered, ASK will re-display the 
prompt and wait for a valid response. The default values for 
Prompt, WARN, and OK are "?", "Y", and "N" respectively so it's 
not mandatory that you specify a string for each. Most of the 
other available ASK type of programs will only work widi a "Y" 
or "N" answer. The ability to define a specific keyword to 
match for the True and False answers is what sets this AEP 
command apan from tlie rest.

Fred Fish Disk *123 or may be ordered from:

Another problem that arises when working with batch 
files is that there is no easy way to make decisions based on 
user input. This would be handy in the script just shown. 
Although there are several P.D. programs that address this 
problem, I prefer the flexibility provided by the ASK command 
found in the ARP collection. I will be covering the AmigaDOS 
Replacement Project commands next issue. ASK allows you to 
suspend execution and wait for input from the keyboard. The 
syntax is: 


Prompt is a string that will be displayed in the console 
window. TIMEOUT is a set time limit in seconds. To test the 
WARN and OK values we can use IF WARN and ELSE state- 
ments. Let's modify the script shown above to handle a 
forgetful user. For this purpose the file is saved as "Paint.stu". 


MOUNTED Pictures: 

ECHO "The Data disk Is not mounted.' 
ECHO "Place volume Pictures: in any drive and enter" 
ASK "C to continue or A to abort." "C" "A" TIMEOUT 10 

EXECUTE Paint.stu : execute this file again 

SKIP Exit 

ASSIGN HR: Plctures:HIRes 
ASSIGN LR: Pictures:LQRe5 
ASSIGN BRUSH; Pictures: Brushes 

RUN Painter 
LAB Exit 


I have shown you a method for changing the Assign- 
ments needed by AmigaDOS to make another disk your system 
CWorkbench) disk. A quicker way to do this is to use the 
DefDisk command. By providing the name of the volume to 
change the assignments to, DefDisk wiU re-assign the logical 
names needed by Workbench to point to the new volume or 

DefDisk <volume name> 

DefDisk DHO; 

This is a lot easier and just as flexible as the original 
metliod. DefDisk may be found on AMICUS Disk #18. 

I'll be covering batch files in detail in an upcoming issue. 
With the help of these and other Public Domain commands we 
will discover some of the power that the Amiga provides. .N"e.xt 
issue I will discuss the differences and improvements in 
command line processing provided by the ARl' command col-

A compiler that makes AmigaBASIC a viable 

development language! 

by Bryan Catley 

Release 1.3 of Absoft's AC/BASIC compiler for the Amiga is now shipping. 
Registered users should receive the upgrade automatically. This release contains no 
external differences, but instead concentrates on improving compatibility with 
AmigaBASIC and fixing bugs. Additionally, a number of routines were rewritten to 
increase execution speed. The result is a compiler that makes AmigaBASIC a viable 
development language! 

The distribution disk includes a number of examples, plus a full set from the 
reference manual. Also included is a short AmigaBASIC program that creates a HAM 
screen and then fills the screen with pixels drawn in random colors. There are two 
problems with this program you may wish to correct before using it. 

First, change both "CALL CleanUpEverythingO" statements to "CALL 
CleanUpEverything", and change the "SUB CleanUpEver)tlTingO STATIC" to "SUB 
CleanUpEverything STATIC". If you do not make this change, and you run the program 
under the interpreter, you receive a syntax error. 

Second, change the two "pen% = INT(RND*31+1)" statements to "pen% - 
INT(RND'63+1)". Tills change allows the full effea of HAM colors to be seen. As 
originally written, only the blue intensity ever gets modified (and even then, only when 
the random number is above 15), so the result is a screen of mostly standard colors! 
The difference is dramatic! 

Other example programs are the BSpread AmigaBASIC spreadsheet (AC V3.1.) 
and programs that show how to access command line or Workbench arguments from a 
compiled program. AC/BASIC also supports a number of language extensions, 
including the CASE statement. If you have been using this extension, you should be 
aware of some usage rule changes — made at the request of Microsoft Corporation — 
with this release. 

My original review of AC/BASIC Release 1.2 (AC V2.9, V2.10.) included a list of 
all the bugs I encountered. With one exception, all those bugs have been fixed. The 
exception is that collision detection is still not handled correctly. As indicated, many 
other changes have been made for increased compatibility, and the mouse handling 
routines are among those which were completely rewritten. They now work 
beautifully... and all the time! 

The documentation has also been changed; rather than a small three-ringed 
binder, it is now a standard soft bound book. Its contents have not been changed 
much, but some additional examples have been added. The print is also larger and 
easier to read. Overall, the documentation is superb, and you will probably find 
yourself using it rather than the AmigaBASIC manual (even when using the interpreter). 

If you are not familiar with the compiler, Absoft does not charge royalties for 
distribution of compiled programs. They do request that you mail in die licensing 
agreement included in die package before distributing a program. 

This release of AC/BASIC is really worth having! If you do any j'XmigaBASIC 
programming, buy it. (It's not expensive!)

Extending AmigaBASIC 

Accessing Intuition Functions From AmigaBASIC 

by John Kennan 

For about 2 years. I have been an active member in the 
Tri-City Amiga User's Group in Midland, MI. As the current 
president, part of my role is helping group members use their 
Amigas more effectively. Recently one of our members ap- 
proached me and asked if it were possible to create borderless 
windows in AmigaBASIC. He was working on a project involv- 
ing overlaying text on a video signal using a genlock and an 
Amiga. The genlock substituted the video signal for the back- 
ground color in Amiga windows and screens. An AmigaBASIC 
program generated text for the video. The problem was that 
windows created from within an AmigaBASIC program always 
included a window border which was visible in the final 
videotape. I took a quick look through the AmigaBASIC manual 
and found that AmigaBASIC gave the user very few options on 
window management. None of the available options allowed 
creating borderless windows. Since AmigaBASIC always creates 
windows with borders, I needed to come up with a way of 
making a window border transparent. The simplest way would 
be to tell the Amiga to make the border color the same as the 
background color. Once again, AmigaBASIC offered no obvious 
way of doing this. 

After studying the problem, I realized the only way to 
remove a window border was to access Intuition data structures 
and functions. Unfortunately, tliis advanced topic is not covered 
in the AmigaBASIC manual. This article attempts to remedy this 
problem by demonstrating the procedure for calling some of the 
Intuition routines. Intuition.bas, the program accompanying this 
article, includes some of the most useful calls. The program 
name is derived from the fact that the routines are available as 
Rom Kernel calls when the Intuition Library is opened. 

For those of you in a hurry, I'll start with a quick 
description of how to get Intuition.bas up and running, and 
then we'll go into a brief discussion on how the program works. 

Before typing in listing 1, you'll have to do a few things. 
For AmigaBASIC to access Intuition calls, the Libs: directory of 
your Workbench must contain a file named 'intuition.bmap' . 
Unfortunately, it is very likely that you don't have that file. Don't 
worry, all is not lost. The file is ver>' easy to create using a 
B.\SIC program found in the BASICDemos drawer of the Extras 
disk that came with Workbench 1.2. Simply load the program 
ConvertFD and enter 'run'. The program will prompt you for the 
name of an .fd file to convert. At this point, enter 'Extras:FD1.2/ 
intuition_lib.fd'. The program prompts you for the name of a 
•bmap file to create. If you have a dual drive system, you can 
have ConvertFD create die file direcdy in the Libs: directory by 
entering 'Libs:intuiiion.bmap'. If you have a single disk drive, 

you can save yourself a lot of disk swaps by entering 
'Ram:intuition.bmap'. The file intuition. bmap will be created in 
the Ram: disk. It is then a simple matter of going to a CU 
window and entering 'Copy Ram:intuition.bmap to Libs:'. 

If you already have a copy of the file intuition.bmap, you 
may want to go through the trouble of creating a new version of 
the file. The reason is that the file 'intuition.bmap' contains in- 
formation that tells AmigaBASIC how to call Intuition functions 
by name. Older file versions might not include function calls 
added to version 1.2 Cor 1.3) of the operating system. 

Now type in and save listing I. Intuition.bas is a program 
to demonstrate some of this new function calls. Included are 
routines for making window borders invisible, resizing win- 
dows, moving windows, and moving screens. To see the 
demonstration, enter 'run' . 

Understanding how this program works will allow you to 
better understand the inner workings of the Amiga. This should 
allow an AmigaBASIC programmer to explore other Library 
calls. Furthermore, if at some future time you decide to make 
the transition to another programming language such as C, 
Forth, Modula-2, or assembly language, this information will 
help you get started. 

Most of the Amiga operating system's inner workings 
revolve around structures. In the "C" programming language, a 
structure type is first defmed as having a certain format. The 
format defmes die number of bytes of memory an occurrence of 
the structure requires, and the sequence and size of the data to 
be stored in the structure. After that die program can allot space 
for an occurrence of die structure and store data in the structure 
according to the structure's format. Any program can then 
access the information if it knows the format and the starting 
address of the structure, 

A powerful feature of structures is that they will often 
contain addresses which point to other structures (thus a 4 byte 
address is referred to as a pointer). In this way structures can be 
linked together through a series of pointers. Thus a single 
structure can form the beginning a linked group of structures 
(sometimes referred to as a linked list). Linked lists of this type 
are fundamentally import to die Amiga Rom Kernel in keeping 
track of what occurs in the .\miga multi-tasking environment. 

An example of one of die most important structures 
available in Intuition - the Window structure will make this 
dear. The Amiga uses this struccure to keep track of information 
pertinent to window management. Rather than describe die 
entire structure (it contains 48 different entries), we'll just look 
at some of the highliglits to get a flavor for the type of informa-

Notice that the above structure contains a variety of 
inlbrmation. Data within a structure may be stored as a byte, 
short word (two bytes), long word (4 bytes), or just about 
anything else. Fortunately Amiga BASIC includes the commands 
a iDrogrammer to easily access data in a structure no matter how 
ths data is stored. 

The most important thing to remember about structures 
is that while there are many structure types (i.e. Window, 
Screen, Gadget, Requester, etc. are all structures defined by 
Intuition), once a structure type is defined, all structures of that 
type will have the same layout. Thus there may be many 
Window structures resident in memory, but tlie 10th and 1 1th 
b^te of each of those structures will always describe the height 
of diat Window structure's window. 

Anyway, a structure's real power is in passing informa- 
tion from one part of a program to anotlier part, such as a 
subroutine. Rather than passing the 48 variables defined in the 
■Window structure, we can pass just one number — the starting 

address of the Window structure. The subroutine can then 
extract any information it needs from the strucaire simply by 
knowing the offsets that define where the information is stored. 
Most of the Intuition Rom Kernel routines require as input the 
address of the Window structure that describes the window of 

In principle, all of the Intuition Library calls could be im- 
plemented from AmigaBASIC. In practice, most of die calls 
require a great deal of preparadon which might make them 
difficult to use. We will focus on the ones which are easy to 
implement and offer the added benefit of overcoming some of 
AmigaBASIC's more serious limitations. For example, once you 
create a window or screen from within an AmigaBASIC pro- 
gram, the program has virtually no control over that window or 
screen. Fortunately, the Intuition library calls change this 
situation dramatically. Below is a list of die calls used in listing 
1 . Within the program, Rom Kemel routines are called by name. 
The more useful calls (from a BASIC programmer's point of 
view) are as follows: 

WindowToFront(MyWindow&) - Moves the specified 
window to the front of the screen 

WindowToBack(MyWindow&) - Moves the specified 
window to the back of the screen. 

RefreshWindowFrameCMyWindoiv&)- When you move 
or resize a window under program control, Intuition sometimes 
gets confused and fails to redraw the window's border. This 
routine was added to version 1.2 of the operating system to 
allow programmers to force Intuition to redraw the border. This 
routine is useful as it allows a programmer to modify the

Window structure and then force the Amiga to redraw the 
border. Tliis is how we make the border disappear in the demo. 
ScreenToFronrCMyScreen&) - Moves the specified screen to the 
front of the display. 

ScreenToBack(MyScreen&) - Moves the specified screen 
to the back of die display. 

Move\Vindow&(My'Window&,dx%,dy%)- Moves the 
window by die specified number of pixels left or right and up 
or down. 

SizeWindow&(MyWindow&,dx%,dy%)-lncrezses or 
decreases the size of the window by the specified number of 
pixels left or right and up or down. 

In the calls listed above, function's name is followed by 
its required parameters. I have substituted variable names for 
the parameters. The '&.' symbol indicates eitiier that the variable 
is a long integer, or diat die ROM call returns a long integer. 
The '%' symbol indicates that the variable is a short integer. 

All of the calls listed above require the address of die 
window's window structure as a parameter (as indicated by tlie 
variable MyWindow&). This address is readily obtained by 
forcing die window to become the current window witli the 
AmigaBASIC command WINDOW OUTPUT <window-id>, and 
then getting the address of the window structure with the 
statement WINDOWCT). Save this value in a variable for later 
use. Listing 1 includes examples using all the above calls. 

All the calls l^ecome available when the Intuition Library 
is opened with the LIBRARY statement. AmigaBASIC restricts 
use of Library calls. If a Library call has multiple parameters or if 

it returns a value, it must be defined in advance with a DE- 
CLARE FUNCTION statement. Furthermore, once a call is 
defined in a DECLARE FUTs'CTION statement, it can only be 
used in an arithmetic expression. For example, the following 
program will open the intuition library and then decrease the 
size of the default AmigaBASIC window. (Make sure the 
window is open and of sufficient size so diat shrinking the 
window 5 pixels in the x and y direcdons won't crash the 

LIBRARY "Intultion.iibrary- 



My Window&=WI NDOWC7) 



Exercise caution when using Inmition ROM Kerne! 
routines. Remember ROM calls are outside of the control of 
AmigaBASIC and errors will not result in the relatively benign 
AmigaBASIC error codes. To recover from an error in a ROM 
Kernel call, you will probably have to reboot die machine. To 
avoid errors, make sure the window to be operated on is open 
and that the parameters passed to the routine are in an accept- 
able range. 

Listing one also includes some subprograms which make 
ROM Kernel calls a little easier to use. CALL 
SetWindowSize(MyWindow&, WWiddi%, WHeight«/o) will set tlie 
window to the desired width and heiglit. The advantage of 
SetWindowSize over SizeWindow is that SetWindowSize accepts 
the desired window size as parameters and dien does tlie 
required error checking before calling die ROM Kernel rouUne 
SizeWindow. CALL KiliBorder(MyWindow&) and CALL 
RestoreBorder(MyWindow&) are used for removing or reinstat- 
ing the border on an AmigaBASIC window. 

By the way, KillBorder and RestoreBorder only effect the 
border. These subprograms will not effect gadgets within the 
window border. Therefore if you want the border to completely 
disappear, create windows without gadgets (read over the 
Window command in die AmigaBASIC manual). It is also 
advisable to leave out the Window Close gadget since this 
prevents the user from closing a Window the program may later 
try to manipulate. 

Listing two contains a small demo program which I used 
at our club meeting to demonstrate borderless windows in Ami- 
gaBASIC. The program superimposed scrolling text on a 
background video signal using a genlock de\ice. As an aside I 
might mention that in my first version of this program I used the 
BASIC SCROLL command. I discovered that repeated Lise of the 
SCROLL comniand causes die Amiga to use up memory rapidly. 
Furthermore, the memory is not deallocated when the BASIC 
program is terminated. Left on its own, a program repeatedly 
using the SCROLL command will crash die machine. I suspect 
diat die problem originates in a bug in die Rom Kernel routine 
ScrollRaster. Hopefully this will be fLxcd in the next revision of 
die operadng system. 

That about covers our introduction to using LIBRARY 
calls from AmigaBASIC. If you want to learn more about the 
ROM calls that are available, you might want to examine die FD 
files in the FD1.2 drawer on the Extras disk. AH Rom Kernel 
routines are listed in these files. Learning how to use them 
might be a litde tricky. You might want to seek help from other

Patch Librarian Files 

(or, '^How to get your sounds from there to here^') 

by Phil Saunders 

When I bought my Yamaha DX7 synthesizer, I also 
bought a used patch editor for the Macintosh. The musician I 
bought it from told me he had, "about a thousand patches", 
stored on the disk. I started using the DX7 with my Amiga 1000 
and a MIDI interface, but tlie thought of those thousand patches 
haunted me. I knew there must be a way to use them M/ith my 

One afternoon I hooked my girlfriend's Macintosh to my 
Amiga with a null modem cable and transferred all the patch 
files. Now I had tlie files on an Amiga disk, but my Amiga patch 
editor refused to recognize them. Whenever I tried to load the 
Macintosh files, my patch editor showed a screen full of 
garbage. I soon realized that the Macintosh editor stored DX7 
patch data in a different format from Dr. T's DX-Heaven. What I 
needed was a way to convert the Macintosh files into Dr. T's 
files. After some research, I was successful. 

The techniques I used can be modified to translate 
sounds for any syntliesizer to Amiga format, regardless of the 
editor or computer used to save the patches. The same tech- 
niques can also be used to convert other kinds of data for use 
in Amiga programs. Here's how to go about the task. 

Compare 'em 

The first step is to compare a few of your existing Amiga 
patches to the "foreign" patches. In my case, after USTing both 
files, I saw thiat the Macintosh file was 4352 bytes long, while 
the Amiga file was 8192 b>-tes long. Checking Howard Mas- 
say's, "The Complete DX7^ I discovered that the Yamafia format 
for a bulk voice dump is 4096 bytes long (128 bytes times 32 
voices). "The Complete DX7" also showed how the various 
parameters of each voice were stored within those 4096 bytes. I 
now knew the Yamaha format for a voice dump. (This informa- 
tion is usually in the oack of a synthesizer manual, under the 
MIDI implementation section or the system exclusive code 

The next step is to compare both patch files to the 
synthesizer's own patch format. You could use a disk or file 
editor to do this; I used the TYPE command with the OPT H 
extension. (TYPE AmigaPile to PRT: OPT H). This gave me a 
printout of both the hexadecimal and the ASCII codes of each 
file. (See Listings I and 2.) The T\TE command is useful 
because it provides two ways of looking at ever>' byte in the 
file. The ASCII printout on the right side allows you to scan the 
file for intelligible information; the hexadecimal values on the 
left let you get precise values of the data. 

In this case we can quickly locate the name of the first 
patch in the Amiga file. Yamaha DX7 patch names have ten 
characters in ASCII format. Looking at tlie right column we see 
tliat "AC.PLANO" starts at $76 and ends at $7F. The ASCII char- 
acters in the patch name are a good due to how the patch data 
is stored. Examination of the Amiga file shows that voice names 
recur every 128 bytes until location $OFFF. (The first name is at 
$76-$7F, the second name is at Sf6-$FF, the diird is at $176- 
S17F, and so on through the thirty-second, which is at $FF6- 

Since a DX7 patch takes up 128 bytes in bulk dump 
format, the patch data is clearly stored in this first part of the 
file. If we compare our listing of the Amiga file to the DX7 
system exclusive data in the book, we see that DX-Heaven 
appjears to store data in the same order as the DX7 system 
exclusive commands. (Most voice editors will conform to the 
manufacturer's bulk dump format because they need to send 
the data to tlie synthesizer in that format.) Looking at the ASCII 
dump after $1000, we see text strings showing the performance 
function data for the DX7. Since this information is not included 
in the 32 voice bulk data dump, we will ignore it. (Some 
synthesizers do save performance data with dieir patches. 
Usually this data will be pan of the patch, so no special steps 
will be necessary to retrieve it). 

What 's you rname? 

We now know that the first 4096 bytes of the Amiga file 
are the same as the standard Yamaha format. But what about 
the Macintosh file? Let's try the same technique of looking for 
the patch names. The third through sixth bytes have some ASCII 
data, but they are surrounded by hexadecimal zeroes. That 
doesn't seem right, so we keep scanning. Looking further on, 
we see the string "A-2" starting at $F8-$101. The patch names in 
the Macintosh file also recur every 128 bytes, so we find the 
next name at $178-5181, followed by another at $1F8-S201, and 
so on. We'll assume that Opcode didn't devise a custom data 
format since die amount of space between patch names is the 
same as the Yamaha specificafions. So, the Macintosh file looks 
like the Yamaha bulk dump format, but with a lot of extra data 
tacked on to the begirming. 

In the Yamaha format, the patch name takes up the last 
10 bytes of the 128 allocated for eacli voice. The first 118 bjtes 
contain data for the other parameters in the voice. So, if we 
want to find the first byte of any patch, we need to look for the 
location of the first byte of its name and then subtract 1 18. If we 
do this for the Amiga file, we find the first byte of the patch 
name at $76 (decimal 118). If we subtract 118 from this value, 
we get zero. The file starts at $0000, so diis makes sense. 


Amazing Computing V3. 12 ©1988 

The Macintosh file has its first patch name at SF8 
(decimal 248). If we subtract 118 from 248, we get 130 (S82). 
This means that the first voice in the Macintosh file starts at S82 
and runs for 128 bytes (to SlOl). The second goes from S102 to 
Sl81, with the last patch ending at $1081. We want to extract 
the data from $82 to $1081 (Decunal 130 to 4225) and discard 
the rest of the file. I wrote a simple utility, CONVERT, which 
will skip a user specified number of bytes into a file and then 
write a new file of the specified length. 

Convert It! 

To convert "Macflle" to Amiga format, we would use the 
following command: "CONVERT dfOrMacfile 
dfO:AmigaFormat.TX7 130 4096". ("Convert Macfile to 
AmigaFormat.TX? by copying 4096 bytes after skipping 130 
bytes".) The output file created by the CONVERT command is 
ready to be loaded into DX-Heaven or a public domain program 
like DX-fer. The actual conversion of the file is easy; the 
difficulty is in finding what bytes need to be skipped and which 
need to be kept. There are several standard steps in doing this 
kind of file conversion. I will summarize them in general terms. 

1: Get hexadecimal dumps of the different file formats. 
The "TYPE OPT H" command is useful for this purpose. If you 
have access to the program that generated the file you wish to 
convert, try entering the same data in both programs and then 
comparing the resulting files. This is about the only way to do a 
conversion if a program rearranges data. (Few^ patch editors will 
do this). 

2: Examine the "standard" format. Most manufacturers list 
their system exclusive data formats in the synthesizer manual. 
Even if the information is not listed in the standard manual, it 
may be available in other books or by request from the manu- 
facturer. A public domain program that accepts raw MIDI 
system exclusive dumps is another way to get a look at what 
format tlie synthesizer expects. 

3: Look for landmarks. In our example we looked for the 
ASCII codes tliat represented patch names. Once we found 
these we could look for patterns that recurred (patch names 
being 128 bytes apart, for example). This kind of analysis gives 
you useful information about how data is stored. 

4: Compare the different files. Do the patterns repeat the 
same way in each file? Where is the "good" data stored? How do 
the files you are trying to convert differ from the standard 
format' These are the kinds of questions you should ask 

5: Find the start and end points of the data you want. If 
you know that each voice in the file starts and ends a certain 
distance after your "landmark", you should be able to locate the 
data you want. The CON'VERT utility is a very useful tool for 
extracting data — once you know which data you want. 

6: Put the new file in proper format. This step is unnec- 
essary in our example. But if we needed to add a "header" so 
that data could be read by an application program (a program 
that required IFF format samples, for example) we would have 
to create the header and then JOIN it to our new data file. One 
easy way would be to use CONVERT to extract an existing 
header, then use a disk editor to alter it to match the foreign 
file. The header could then be JOINed to the new file. You can 
also use CONVERT several times on a file to extract different 
data, then use JOIN to rearrange the pieces. This hasn't been 
necessary in my applications, but it is certainly possible. (See 
Richard Rae's article in the Sept. 1988 issue of Amazing Comput- 
ing for more details on IFF format sounds). 

A general rule for translating Yamaha DX7 files is to find 
the location of the first patch name and then subtract 118. The 
result i,s both the start of the patch data and the number of bytes 
that should be skipped. In the example cited in the article, the 
first patch name starts at SF8 (Decimal 248). If we subtract 118, 
we get 130 (S82), Since the first byte of the file is numbered at 
SCXXX). the byte located at 130 is actually the 131st byte in the 
file. By skipping the first 130 bytes and extracting the next 4096, 
we extract the patch data. I have compiled a list of skip values 
for several DX7 patch formats, Refer to Table 1 to get the 
correct value, then use the CONVERT command to convert the 
file to Amiga format. (Other synthesizers are handled in the 
same way, although the starting offset,H8 in this case, will 
probably be different.) 

The CONVERT utility gives you access to the thousands 
of public domain sounds that exist on bulletin boards across the 
country. I have used it to convert more than three thousand 
DX7 patches for use on my Amiga. It does require a little work, 
but once you learn how a file is stored, you can conven all files 
of that type with little additional effort. I hope you find CON- 
VERT as useful as I do.

C niotee ^Mtn tke C (ff^-oap 

by Stephen Kemp, PUNK ID: SKEMP 

Program or function control must often be determined by 
the value contained in a variable, or by tlie results of an 
expression. For instance, most programs that accept keyboard 
input have code that determines the program functions to 
execute — based on the keystroke. The evaluation of the 
keystroke determines what happens next in the program. 

There are several ways to write the code to handle this 
type of program control. The first method that springs to mind 
is use of multiple "if' statements to check the conditions and 
then direct the program. This is a ver)' logical choice, especially 
when there are only a few possible branches. But when there 
are many possible branches, the best method to control 
program flow may be the "switch" statement. 

The Switch Statement 

The "switch" statement evaluates an expression (or 
variable) and uses the results to match the expression with one 
of many branches. The syntax of the switcli statement is: 

switch (expression) ( 

cose constant 1 : statements 
case constant 2; statements 

cose constant n: stortements 
default: statements 

The expression determines branching within a switch 
statement. The results are compared to each "case" that has 
been defmed and the statements foUowing a match are exe- 
cuted. If no matching "case' is found, the "default case" is 
executed (if it is defined). 

W}}icb Case? 

Lets take a closer look at the switch statement. The 
expression can be a single variable, the result of a function call, 
or any other valid statement. "Case" statements within a switch 
statement serve as branch labels and must include a CONSTAJ^ 
value notz variable. For example "case 3: " is a valid case 
statement, while "case vaix:" is not valid, since varx is not a 
constant. Remember, the case must be labeled by a con Lant 
vaJue or a constant expression. 

A switch statement can contain any number of cases, but 
no two case constants may have the same value. To cause a 
branch to occur, the constant value must exactly match the 
expression's results. The only exception to this rule is the 
"default" case. (Notice that the "default" label does not actually 
have the word "case" preceding it.) If a default case is included 
(it is optional), and the expression does not match one of the 
cases, control branches there. 

It is important to note that the cases are merely labels. 
Once the label is "jumped" to, control continues to fall through 
the remainder of the switch statement. (This is analogous to the 
goto statement and label.) When more than one "case" is 
expected to execute the same code, this "fall through" condition 
can be used to your advantage. However, more often you want 
execution of code to end before following into another case. 
This is accomplished with tlie "break" statement. 

Gimme a Break,' 

The break statement serves a similar purpose in the 
switch statement and within loops. When a "break" is encoun- 
tered, program control jumps to the next statement following 
the switch statement. The break statement is important to 
proper functioning of the switch statement. To see how the 
break can be used, look at this example: 


/' detefmine what to do with value '/ 

easel: /' if value = 1 then '/ 

statements /" do some statements 7 
breal{; /'cose ! Is complete, end switch 7 

case 2: /* if vaiu© =■ 1 then "/ 

statements /* do these statements 7 
break; /• case 2 now complete "/ 

default: /■ if value is some other value '/ 

statements /* do these statements 7 
break; /' the default cose is complete 7 


Break statements transfer program control once a case is 
completed. If the break statement is omitted between case 1 and 
case 2, whenever the value matches the first case, the state- 
ments of both case 1 and 2 are executed. Notice that a break 
statement again occurs after the default case. Although it is not 
necessary to have a break after the last case in a switch state- 
ment (because the next statement to be executed comes after 
the switch instruction), it is still a good practice. The break may 
help avoid an error in execution if another case is later added to 
the end of the switch. 

Notice the format used within the switch statement. The 

syntax diagram shows that ihe statements can begin anywhere 

after the colon in a case statement. To make the code more 

readable, most people prefer to place the case labels on 

separate lines. Additionally, notice tlie indentation. Some people 

like to keep tlie case statements lined up with the switch 

statement; otliers prefer to indent. Almost everyone agrees, 

though, that the statements should be indented after the case

Each case is compared to the value, and the default case 
is taken only if no match is found. This means the order of the 
case statements is not important. In our last example, the default 
case could be at the top (case 1 could follow case 2), and the 
statement would still function the same way. For easy mainte- 
nance and understanding, I recommend tliat you order the case 
statements whenever possible, and place the default at the 
bottom. This set-up makes it easier to detennine if every 
possible branch has been included. 

You may notice that I mention little regarding the 
statements following the cases. These statements can be any 
valid C instructions, including other switch statements. The only 
important point to remember is that once execution has begun 
at a case label, it continues through the remainder of the switch, 
unless a break statement is encountered (or a goto statement, of 

Let's Code.' 

To help us understand the switch statement let's write a 
program. Here are the parameters this program should follow: 

1.) Count the number of times the keystroke '1' is entered. 
2.) Count the number of times '2' or '3' or '9' are entered. 
3.) Count the number of times any other keystrokes are entered. 
4.) Print die results of each count then terminate the program 
when 'Q' or 'q' are entered. 

When you have finished writing the program, it should 
look something like the program in Listing one. If you have 
problems, don't be afraid to seek assistance from my example 
or a language reference manual. After your program works suc- 
cessfully, proceed to expanding or alterations. Remember, you 
can learn a lot from experimenting.

Easy Menus in JForth 

The EZMenu system makes it quite easy to implement 
simple text based mentis 

by Phil Burk 

Never Used Forth? 

If you have already programmed in Forth, skip ahead to 
the next section! 

I won't try to teach you Forth in this article. But hope- 
fully I can explain enough so thai the program listing makes 
some sense. In Forth, subroutine, or function is called a 
"word". The defmition of a word is started wth a colon, ':', 
followed by the name of the word. The definition is terminated 
with a semicolon, ';'• A program called HI that prints out "Hello 
World!" would be defined as follows: 

:HI .'Hello World!-; 

This could be compiled interactively in any Forth in 1 or 
2 seconds. Once compiled it is added to a dictionary of com- 
mands, any of which can be executed interactively or refer- 
enced in another program. Thus, Forth is both a compEer and 
an interactive environment. 

Forth code looks a little strange at first since it uses 
Reverse Polish Notation. In Forth, numbers and addresses are 
held on a stack. The Forth words operate on this stack in the 
order of their appearance in the code. The syntax is therefore 
very simple, being much like English. Here is some code that 
places two numbers on the stack, adds them together with 
"plus", then prints the answer using "dot". 

23 45 + . 

The answer, 68, would be printed if you ty]>ed this into 
any Forth. 

Most of the common Hinctions in Forth are standardized. 
However, the way in which Foith is interfaced to an operating 
system has not been standardized. Thus, this program, which 
uses Amiga Intuition Menus, will only compile under JForth 
from Delta Research. The EZMenu toolbox is unique to JForth, 
but almost every Forth on the Amiga allows you to access 
Intuition Menus in some way. 

Wtiy Use Pull Down Menus? 

If you're like me, when you buy a new interactive 
program you want to tr>' it out NOW! You pop in the disk, click 
on some likely looking icon and you're in. Now what.' While the 
manual sits unopened in tlie box you probably start exploring 
the puU down menus. If the user interface is well designed you 
can get pretty far this way. After your initial frenzy subsides, and 

you get in deeper, you can always consult the manual to teU 
you what you've missed. 

If you are writing a program for others, providing a good 
set of menus is obviously important. Adding menus to your 
Amiga program, however, is no trivial matter. The Amiga menu 
system is so flexible, and has so many options, that it can take a 
lot of work even to do somed^ing simple. I am very grateful to 
the folks at Amiga for providing a very well thought out menu 
system that can handle almost anything. But when I was just 
writing a simple text menu, I used to wish for an easier way. 
For this reason, I wrote the EZMenu system and included it with 
the JForth compiler. The EZMenu system makes it quite easy to 
implement simple text based menus which are the most 
common type. If you choose to do something fancier, like 
including graphics in your menus, you will have to do a bit 
more work. 

[Note: JForth is a Forth '83 based compiler similar to the 
MultiForth system described in previous Amazing Computing 

Amiga Intuition Menus 

To understand how EZMenu system works, it helps to 
have some idea of how the Intuition Menu system works. 
Intuition Menus use several different structures linked together. 
(See Figure 1. for a diagram of this system.) The primary 
structure is the Menu structure. This structure determines where 
the menu appears on the menu bar, its name, and its size. Tlie 
Menu structure points to a linked list of Menultems. 

Each Menultem has its own size and position, plus 
information on how to draw it. Each Menultem points to either 
an IntuiText structure or an Image structure. Thus you can mix 
text and graphic images in a menu. Menultems also have a 
number of flags that control whether it has a checkmark, how it 
is highlighted, whether it has a command key, etc. Menultems 
may also have a pjointer towards a list of Subltems. 

The IntuiText Structure has a pointer to the text, plus in- 
formation on position, font, colors, etc. Multiple IntuiText 
structures can be linked together into lists. Image structures 
allow you to specify a bit mapped image, which bit planes to 
use for highlighting, size and position, etc. Images can also be 
linked together. 

The primary Menu structures can be linked together to 
form a Menu Strip which can be connected to a window. When 
you select a window, its Menu Strip is made available. When 
you pick from a menu, a MENUPICK event is sent to die 
window for use by your program. (continued)

figure 1 

Although complicated, the Intuition Menu system is very 
powerful and flexible. The JForth EZiMenu system was designed 
to make it easier to use these menus in your programs. 

JForth EZMenu System 

The JForth EZMenu system makes some assumptions 
about how you'd like your menus to look. Using these assump- 
tions, it can do most of the work required to set up an Amiga 
Intuition menu. EZMenu assumes diat the Menultems will be 
lines of text arranged vertically, "regular menus". You simply 
specify how many items to liave and what the text will be. You 
can then deEermine a Forth word to be executed when you pick 
each item. You may also add command key equivalences, 
checkmarks with mutual exclusion, and other custom features as 

The EZMenu system is based around a special JForth 
structure called the EZtMENU. This structure contains a complete 
Intuition Menu structure, plus a pointer to a block of IntuiText 
strucaires and a pointer to an array of CFAs, one for each menu 
item, and a count of how many menu items there are. You 
create one of these structures for each menu wanted. Most of 
the EZMenu routines uses this structure as one of its parameters. 

l£t's look at a simple interactive graphics program 
written in JForth to see how this EZMenu system is used. 

Step by Step 

This program will open a window and begin drawing 
colored lines or boxes in a random walk pattern. The puU down 
menu offers four choices. You can select between lines or 
boxes, clear the window, or quit. 

The numbers in parentheses in this article correspond to 
numbers in the listing. This should make it easier to match code 
with the text. 


Amazing Computing V3.12 ©1988 

(1) Compile any code needed for this program. This 
includes the graphics toolbox, the event handling tools, the 
EZMenu system, and a random number generator. 

(2) Declare a copy of an EZMENU structure as described 
above. We will be using only one menu. 

(3) Define the words and variables that control the 
drawing mode. The variable DRAW-MODE is set by picking 
Lines or Boxes from the menu. This variable is then used by 
another routine to decide what to draw, 

(4) Define a word to dear the window. This demon- 
strates how to call an Amiga library routine from JForth. We will 
use the Amiga SetRast function to set the entire RastPort to the 
background color. The first line in CLEAR. WINDOW gets the 
address of the current RastPort. This variable will be set when 
the windo'w is opened. The routine is called with the line; 


The CALL word in JForth builds a call to the named 
routine by searching the Amiga "FD" files for the necessary 
information. It figures out which parameters go in which 68000 
register, determines the offset of the routine in the library, then 
builds the proper 68000 machine code. This system will work 
with any Amiga library that has an FD file including the ARP 
library, custom MIDI libraries, or whatever. 

(5) The word MY-MENTJ.INIT initializes the menu. First 
we set die width for the menu items to 10 pixels. Then we dy- 
namically allocate the structures needed for our 4 menu items 
with the line: 


The word EZMENU.ALLOC allocates enough memory for 

4 Menultems and 4 IntuiText structures and attaches them to 
MY-MENU. It also allocates space for 4 CFAs. The next com- 
mand line uses EZMENU.SETUP to give the menu a name. It 
also initializes all of the Menu, Menu Item, and IntuiText 
structures to reasonable defaults, then links these structures 
together into a complete Intuition menu. 

We now use die word EZMENU.TEXT! to specify the text 
for each menu item. Notice how we use the word 0" to 
generate the NUL terminated, 'C like, text strings needed by 
Intuition. We now use EZMENU.CFAO to tell the EZMenu system 
what to do when a menu item is picked. We could set each one 
individually like we did with the text above, but I decided to 
use a DO LOOP just for fun. We could stop here and have a 
workable pull down menu. Let's continue, however, and make 
them a litde fancier. 

C6) Put a checkmark beside the Lines or Boxes item in 
the menu to show which one is current. We can use the 
Amiga's mutual exclusion feature to make one check mark 
automatically disappear when the other appears. Intuition 
allows you to give each menu item a bit pattern. When you 
select a menu item, its pattern tells Intuition which other menu 
items to turn off. There are 32 bits in the pattern but we will 
only look at the 4 lowest bits since we have only four items. 

When we select menu item I, "Boxes", we want menu 
item 0, "Lines" to become unchecked. The "Boxes'* item would 
now have the checkmark. The other items will be unaffected. 
Thus the exclusion pattern for Boxes should have bit set to 1. 
The bits are numbered from right to left, 0-31. Thus the pattern

for "Boxes" should be 0001. For "lines" to turn off "Boxes" the 
pattern should be 0010. The binary patterns for each menu item 
are shown below. 


= item # for each bit 




= turn otf item 1 . Boxes 




= turn off item 0, Lines 


-bit 2 


= ieave others aione 


-bit 3 


We also need to put a checkmark beside the "lines" item 
since the program starts that way. 

(7) We can easily assign a command sequence for menu 
items using the E2MENU.COMMSEQ! word. Now when the 
program is running you will be able to hold down the "right 
Amiga key" and then hit a 'C on the ASCII keyboard to Clear 
the window. The menu initialization is now complete. 

(8) This code is responsible for drawing the lines and 
boxes. SAFE. RE CT sorts the comers of a rectangle before 
drawing it. The Amiga does not check for backwards rectangles 
(for speed reasons) and freaks out if you try to draw one. 
Notice the use of GR.RECT, is one of theJForth graphic routines 
which start with the prefix "GR". (The JForth graphics toolbox is 
based on the concept of a current window. Most JForth graphics 
words operate on the RastPort of that window.) 

The word WANDER.XY is interesting because it uses 
JForth's structure referencing tools. If you have done any Amiga 
programming, you have no doubt encountered the use of 
structures. Stnictures allow you to package together the data 
needed to describe something in the computer, like a window 

or menu. In this word, I wanted to keep the lines and boxes 
from going outside the window. I couldn't just use the original 
sizes because people might resize the window. Luckily, the 
current widtli and height are stored inside the window structure. 
The X position is dipped to the window by the line: 


Let's examine this line in detail. The x value has been left 
on the stack by the previous line. The word MAX takes two 
numbers off the stack and remms the biggest. Thus if our x 
position is negative, zero is bigger and we are left with zero. If 
X is positive, we are left with x. We then get our window 
strucnjre pointer from the variable GR-CURWINDOW. This is 
passed to ..© which fetches the width of the GIMMEZEROZERO 
window from the structure. In 'C this line would look some- 
thing like; 

If (X < 0) X = 0; /* equivalent 'C' code! 7 
xlimit= gr_curwindow->GZZWidth; 
If (x > xllmit) X = xllmit; 

TheJForth word ..® calculates an address by adding the 
offset for die wdGZZWidth member to the structure. It then calls 
either C@ , W@ or @ depending on whether the width is an 8 
bit, l6 bit or 32 bit value. You don't have to know the size of a 
structure member to reference it. We have a saying around here, 
"The size of your member is not as important as what you do 
with itl". The fmal word, MIN, clips the x value to the window 
width. There are more examples of accessing structures in 
section (10). 

C9) This section contains the program's main loop. The 
word LOOP. DRAW draws a line or box then checks to see if the 
user has generated any events. The events are associated with a 
specific window so we must pass EV.GETCLASS our window 
address. It returns an event class. If the class is zero, there was 
no event so we just keep looping. If there was an event we pass 
it to HANDLE.EV'ENT for processing. HANDLE.EVENT only 
checks for two kinds of events, MENUPICK and CLOSEWIN- 
DOW. If a menu is picked, the menu code is passed to 
EXMEIW.EXEC which then figures out the item selected. 
E2MENU.EXEC then caUs the word you specified in section 5 
using EZMENU.CFAO. If the CLOSEWINDOW gadget was hit, 
we set QUIT-NOW which causes LOOP.DRAW to exit later. 

(10) I find it very helpful to separate most programs into 
three sections: Initialization, Execution, and Termination. If you 
look at the fmal word EZWALKER, you can see diis organiza- 
tion. When debugging, I can initialize the application with one 
word, e.g. EZMENU.INIT, I can then examine structures, test 
graphic words, look at variables, etc., under the same conditions 
that the program would execute. When I am done, I can clean 
up with one word. 

At the beginning of this section we declare a NewWin- 
dow structure. This is used as a template for how we want our 
window to look when we op)en it.. We can set the default 
values for this window using: 



Amazing Computing V3. 12 ®1988 

We can dien override these defaults to customize our 
window. In the next two lines, we can give it our own title b>' 
storing the absolute address of a string in the title field of the 
NewWindow structure. The example in section (8) used a 
pointer to a structure. Here we use the structure directly. Note 
also that we use 0" since the Amiga uses zero terminated strings 
instead of Forth style strings. The word ..! is the opposite of ..@ 
as it is used to store values in a structure. 

We need to change a few of the flags to make menus 
work with this application. We set the IDCMP flags to give us 
menu picks and closewindow events using the line; 


The equivalent code in 'C would be; 


By also setting the ACTIVATE flag, we don't have to click 
in the window to active when it opens. This flag is ORed with 
the existing flags. We now open ilie window and associate our 
menu with it using SetMenuStripO. 

The Termination word clears the menu strip, closes the 
window, then frees any memory' associated with the EZMenu. 
The last word EZWAIKER ties everything together. Finally I 
print a message that tells me how to run the program immedi- 
ately after compiling. 


I hope this article will encourage you to use menus in 
your application (if you are not already doing so). To get the 
most out of Amiga's menus you should read the Intuition 
manual. Menus can make your programs easier to use and help 
give them a professional look. 

1 will try to upload this program onto most bulletin 
boards so you don't have to typ)e it in. It shouldn't take too long 
to download. The source code is 5215 bytes. The executable 
image is 9324 bytes and the small image size is because of 
CLONE: an optimizing target compiler to be released in late

Getting Started in Assembly 

Learn to write the software in the 7nost efficient 
computer language available: Assembly 


The surest way to make a powerful computer an 
impotent collection of deficient electronics is to run a program 
written in an inefficient programming language. If the applica- 
tion involves intricate calculations such as floating point math or 
needs to perform a real-time function such as music sequencing 
or animation, a high level language just won't work. The only 
solution is to write the software in the most efFident computer 
language available: Assembly. 

Although C has become the language of choice for many 
programmers, and the de facto standard for the Amiga, it is 
certainly incapable of matching assembly's speed performance. 
In applications where unnecessary, extra machine instructions 
can cause a humanly perceptible delay, a high level language 
like C can ruin a perfecdy good algorithm. 

Unfortunately, there is precious little information about 
programming in assembly on the Amiga. Now I wish to present 
an example implementing some very elementary functions. Al- 
though there is no urgent need for speed in executing tliese 
functions, they demonstrate, in assembly, how to perform the 
following aspects of Amiga programming: 

1) Making a program that runs from the CU 

or WorkBench. 

2) Opening and calling routines in Amiga libraries. 

3) Opening windows and fonts. 

4) Setting up and decoding menus. 

5) Getting and interpreting messages from Intuition 
including keyboard and mouse events, 

and gadget selections. 

6) Outputting text and changing pen colors. 

If you can't do the preceding functions in the language 
of your choice, then you aren't really ■wTidng Amiga software. 

The first step in programming in assembly on the Amiga 
is to become familiar with the Motorola 680OO's instruction set. 
If you don't know what a move instruction is then proceed no 
further. You need to study a book on the 68000. 1 recommend 
"68000 Assembly Language Programming" by Leventhal, 
McGraw-Hill publications. 

Next, purchase an assembler. Amazing Computing, June 
1988, contained a review of several products. The assembler 
should come with some include files which defme certain 
structures and values that we need to reference. 

The disc should contain a start-up code module as 
described in the RKM Libraries and Devices manual on page 
489. You can obtain this start-up code on Fish Discs 101 or 55. 
By calling the first program routine to be executed _main, and 
linking with this start-up code, you will automatically acliieve 

the first goal: a program executable from the CLI or WorkBench 
(provided that you make an Icon for WorkBench). Also, the 
start-up code gets the Exec library's base, called _SysBase, and 
opens the DOS library with the base address stored at 

In describing the example assembly program, Example!, 
I will step through the code in basically the same order the 
68000 executes the instructions, referring to the symbolic labels 
at certain lines. At the top of the listing are some external 
references that the include files with the assembler will resolve. 
These include flies supply the actual values for the symbolic 

The first line to be executed is El in _main. The contents 
of all of the non-scratch registers that will be used are saved 
here. Tl^e registers dO, dl, aO, and al are considered scratch. 
This means these registers can be used without saving die 
original contents. All other registers must be saved if they are to 
be used. Never violate this mle unless you prominendy com- 
ment, at the head of die routine, which non-scratch registers 
will be "destroyed". If a call is made to an Amiga library 
function which uses a non-scratch register, save the register 
before the call, and restore it upon return. At line E2, a call is 
made to the routine, open_libs. 

The routine, openjibs, opens the libraries, font, and 
window die program will access, attaches the menu, and sets 
the initial drawing mode and primary pen color. If all goes well, 
it returns to _main with dO = 1. If an>tliing fails to work, it is set 
up to return dO = 0. If you link with the start-up code, the Exec 
and DOS libraries have already been op>ened, and the base ad- 
dresses stored at _SysBase and _DOSBase respectively. When 
linking, always specify the start-up code first so that it calls the 
application's _main routine. A library' must be opened before 
accessing the routines in it. Whenever a library routine is called, 
the base address of that routine's library must be in a6. 

To open the Intuition library (as shown at line Bl), we 
must call the OpenLibrary routine which is itself a routine in die 
Exec library. That is why _SysBase is placed in a6. The return 
value (in dO) will be the base address of the Intuition library, or 
if the Intuition library doesn't opten. 

Many Amiga funaions return certain values for an error. 
An alphabetical listing of available library routines starts on page 
A-12 of the RKM Libraries and Devices. It tells what parameters 
must be placed in whidi registers, and how to interpret any 
return value. If OpenLibrary returns dO = (error), then storing 
the value at _IntuitionBase will set the Z flag, and we will 
branch to BIO before even proceeding to B2. (There is no need 
for a tst instruction here. In fact, moving a value into another

the ,\iTiiga. Check ou: Lhesc fcat-jrcs and 
you'll see why programmers agree, "DSM 
is the best disassembler currently avail- 
able for the Amiga, bar none." 

• DSM disassembles any Amiga pro- 
gram that docs not use overlays. 

• DSM produces assembler-ready output 
that is 100% compatible with the 
Amiga assembler, assem. Excellent 
results can also be obtained using the 
C.A.P.E. assembler from Inovatroiiics. 

• DSM features true text detection. 

• Improved disassembly is supported 
using the built-in expert system mode.

register is quicker than using the tst instruction to set the flags in 
the status register. Just be careful that the register moved to is a 
data, not address, register. Moving to an address register 
automatically uses the movea instruction which doesn't affect 
ANY flags.) 

At B2, the Graphics library is opened just like Intuition 
except that _SysBase needn't be placed back in a6. It's sull there 
since the Amiga libraries never destroy a6. The address of the 
main task is obtained at B3. Although this particular program 
doesn't use this info, any program that uses multi-tasking and 
ports probably will Since future articles will demonstrate how 
to add these features to the Example 1 skeleton code, we'll get 
the address now. 

At B4, the TextFont structure's address, TextAttr, is 
passed to a routine called OpenFont in the Graphics library. If 
you examine the TextAttr structure in the data section of the 
program, you will note that I want to open the Topaz 8 Font. 
By changing the FontName string to 'sapphire.font', and the 
ySize in TextAttr, I could open a different font. Also I can 
change the FC_STYLE to UNDERUNED (1), BOLD (2), ITALIC 
(4), or EXTENDED (8). 

At B5, the main window is opened via a call to Intuition 
lib. One of the passed parameters is the base of the newWin- 
dow structure. This structure, called WindowSirua, is in the data 
section of the program, and it contains info about where the 
window will be placed, how big it will be, what pen colors to 
use for the foreground and background, which types of 
messages Intuition will send to the window, what type of screen 
the window will be opened upon, what should appear in tlie 

title bar, what types of system gadgets will be in the window, a 
pointer to the list of gadgets that you wish to add to the 
window, as well as info about sizing dimensions. 

Page D-155 of RKM presents a summation of die various 
fields. The IDCMPflags are particularly important to the program 
diat needs to communicate with Intuition. Page D-152 of the 
RKM contains list of the values for all possible messages that 
can be sent. Here are the messages that Example 1 wants 
Intuition to send, the values for the messages, and the bit -s 
which are set by these values.

10 When a key Is pressed or released. 
























Simply add up the values for the desired flags and put 
this value in the IDCMPflags field of the window structure. 
(Remember to convert hex values to decimal before adding 
them). Now when the window is opened, Intuition sets up a 
port for the window which is where these messages will be 
sent. Intuition also gets a particular signal which it associates 
with the ".main" task. This will enable the task to wait for 
messages to arrive at this port from Intuition, and when the 
message does arrive, exec will send tlie program the signal 
Intuition has allocated. 

Many Graphics library routines require the address of the 
window's RastPott. This address can be found at an offset of 50 
bytes from the base of the opened window. The window's 
RastPort address is obtained at B6. 

At B7, the opened font, topaz 8, is set for this window. 
This means any text output to the window will be rendered 
with this font. Also, in the menu strucujres (and any user gadget 
structures) I have deliberately sec any pointers to a TextFont 
structure, to TextAttr in the data section. It is not necessary to 
open and set a font because the default font in Preferences will 
be used, but it is a good idea to do so. Especially with gadgets, 
if text is to be "fit tnbetween" two images, and the co-ordinates 
are set based on an 80 column display. When the program is 
run on a 60 column display, the larger letters may trash some of

exactly the size and style desired. 

Ac 58, the pre-initialized menu strip is added to the 
window. This program contains 3 menus, each menu containing 
3 items. An item in the first menu, Color, will also have 3 
subitems. A menu strip is a long, linked list of structures 
containing Menu, Menultem, and Incuitext structures. The data 
section contains examples of each structure. Menu and Menu- 
Item structures contain info about the item or menu's placement 
(always relative to the top left comer), the dimensions of the 
select box (the box which is drawn around the item that die 
mouse pointer is over), the address of the next member of tlie 
list, the address of any IntuiText or Image structure (the text or 


Amazing Computing V3.12 ©1988 

image that appears in the menu), and a bit mask describing 
which other items need to be excluded when this one is 
selected. A flags field describes what features are to be used for 
this item. A list of possible features for menu items is available 
on page D-146 of the RKM. 

For example, in the PenlSubltem structure, these features 
are set: CHECKIT (1), ITEMTEXT (2), COMMSEQ (4), ITE- 
MENABLED ($10), HIGHCOMP ($40), and CHECKED (SlOO). 
These 6 values are summed, and this sum is placed in the flags 
field of die structure. One of the flags set is COMMSEQ. This 
gives the alternate keyboard command which is indicated in the 
menu by the symbol for the right Amiga key followed by the 
chosen ascii value. I chose to use tlie '1' key as an alternate 
keyboard shortcut for Penl, and so the ascii value for T must 
be placed in the Command field of the structure. 

There are several different methods for highlighting the 
select box. For most items, the familiar HIGHCOMP flag has 
been set, but for one item, Infoltem, HIGHBOX is set instead. 

Note that in the menu, a box is drawn around the item as 
opposed to the entire area being complemented. There will be 
3 subitems for the Color item: Penl, Pen2, Pen3. The seleaed 
pen should have a check drawn before it (CHECKIT), and 
initially, Penl must be CHECKED. Only one pen may be 
selected at a time. The other two must be deselected and 
unchecked. Do this by mutually excluding each pen from the 
other two pens. 

The mutual exclude field is a bit map of excluded items. 
Notice diat for the PenlSubltem, all the bits of the mask (except 
for bit »0 because this is Subltem *0 under the Color Item) are 
set. This means tliat when Penl is selected, all the other 
Subitems (Pen2 and Pen3) will be deselected. Notice also that 
the mutual exclude fields of Pen2 and Pen3 have the appropri- 
ate bits set to exclude tlie other pens. 

LntuiText structures are used for every text string Intuition 
must display. They are used for text with gadgets, menus, and 
requesters. The various fields give info about where the text 
should be printed, what colors to use for the fore and back- 
ground, the drawing mode, and tlie addresses of the actual 
string to be printed, the TexlFont sLrucnjre, and any other 
IntuiText structures linked to this one. An example of this is 

Once the menu has been attached to the window, the 
drawing mode and pen colors are initially set at line 39. The 
drawing mode is JAM2 which means that 2 f)en colors are to be 
used for rendering text. Pen A is set to the color of color register 
*1. This pen draws the actual "outline of the letter to be 
rendered". Pen B is set to color register *0. This pen draws the 
"background beneath the letter". Since this program opens its 
window on the WorkBench screen, we can use only 4 of the 
possible 32 color registers — registers to 3. The background 
jjen is always going to be register 0. (The decision is yours It 
can be changed at any time). The color menu subitems will 
allow Pen A to be set to register 1 , 2, or 3. This is what the 3 
subitems, Penl, Pen2, and Pen3 are for. It allows the letters that 
are printed to the screen to be one of 3 different colors. 

The last operation open_libs performs is to move a 1 
into do. This clears the Z flag so that _main wiU know that 
everything went ok. Upon returning to _matn, the low byte of 
dO is moved into dl. (Again, tliis is quicker than a tst instruc- 
tion). If a zero, something went wrong and the code immedi- 
ately branches to a call to quit_all. Quit_all closes everything 
that managed to open in openjibs. Always dose anything that

was opened before you exit a program. This includes libraries, 
fonts, devices, windows, screens, spawned tasks, and deallocate 
any allocated memory. 

If openjibs was successful, the next step is to find the 
signal number that Intuition allocated in OpenWLndow. This 
signal notifies the task of an arriving message. This signal is 
stored in the message port that Intuition also allocated and 
attached to the opened window. At E3, the base of the open 
window is placed into aO. Then the address of the message port 
is obtained at an offset of 86 bytes. The signal number has been 
stored at an offset of 1 5 bytes. When the signal number is 
obtained (its a number from to 31), its respective bit * of 
register d7 is set. This is essentially a bit mask of the signal. 

At E4, a call is made to GetMsg to determine if there are 
any messages at the port. Perhaps the user was moving the 
mouse while open_libs was executing. (Never trust a user to sit 
quietly by during critical operations), if tliere is a message, its 
address is returned in dO. If no messages, dO = 0. If a message 
exists, the code branches to E7. The message contains info 
about the class of message (mousemove, gadget, etc), as well 
as other info that can be interpreted different ways depending 
upon the class. Intuition uses tlie first 20 bytes of the message 
structure to keep track of the messages. The info we need starts 
at die class field, so its effective address is loaded into aO and 
post-decrement addressing mode is used to jam the other, 
following fields into registers. 

At this point, it should be noted that normally, indexed 
addressing mode is used in accessing Amiga system struaures, 
and symbolic labels are used to represent the offsets. For

example, the previous paragraph mentioned two offsets of 86 
and 15 bytes to obtain the port address and the signal number. 
These numbers can be replaced by the labels wd_UserPort and 
MP_SIGBIT respectively. Adding the statement, INCLUDE 
"intuition/intuition.i" will get the two values from this include 
file. This is done so that if the structure is changed in future 
revisions of the operating system, the program will only need to 
be re-assembled with new updated include files. Personally, I 
loathe include files, and prefer to add my own EQU directives 
to resolve the symbolic labels, but this would have made the 
listing too long here. 

My biggest complaint about using include files is that 
they "hide" important information from you. If I had used 
symbolic labels for accessing the fields of the IntuiiMessage, I 
might not have noticed that all of the fields are adjacent in 
memory, and that post-increment addressing mode could be 
used. The 2 fastest ways to access blocks of memory is via post- 
increment and pre-decrement modes. I use them wherever 
possible though this may make it more difficult to update the 
program if the structures are changed in new operating soft- 
ware. If you are interested in churning out code, and execution 
speed is a minor consideration, program in C. By the way, 
extreme use of indexed addressing mode is one reason why 
Amiga libraries and devices are rather slow. 

Once all the info from the message is stored somewhere 
(in this case 68000 registers), it is imperative that the message 
be replied. Intuition will free the memory. We have all the info 
we want. We don't need the message anymore. 

The class of the message is determined at E9. Remember 
that each of the available classes has its own bit. Depending 
upon which bit is set, that is the class. Refer to the above 
IDCMPflags chart for the bit assignment. At this point, the 
program branches to the proper handler for the class. For 
brevity, I have substituted dummy handlers for all of the classes 
except MenuPick (not one of my attributes). In future articles, 
some useful handlers for the other classes will be devised and 
substituted for the dummy ones. 

If the message is MENUPICK, then _main branches to 
decode_menu. The important field is the Code, which was 
stored in d5. For a MENUPICK, the Code contaiiis the selected 
subitem number (if there was one), the item number, and the 
Menu number where the item resides. AH these numbers are bit 
packed into that one WORD in d5. First, we check if the user 
backed off without selecting anything at all. If so, d5 will = -1 
(MENUNULL). If sometliing was selected, the menu number 
must be determined since tlie program has 3 menus. By 
AND'ing with SIF, the bits that represent the menu number are 
isolated from the bits representing the item number and the 
subitem number. Once the menu is determined, the appropriate 
handler is called. Tlie item number within this menu must be 
determined next. This is done precisely the same way as 
determining the menu number, except that the bits which need 
to be examined must be shifted to the low bits of the register. 
Finally, if a subitem of an item was selected, this needs to be 


Amazing Computing V3.12 ©1938 


Let's assume that the user selected the Pen3 subitem in 
the Project menu. The class of the IntuiMessage is ME^^JPICK, 
so _main branches to decode_menu. At Fl, the menu number 
bits witliin tlie Code are isolated and evaluated. Since the 
Project Menu is the first in the linked list of menus, it is menu 
#0. The branch is taken to F4 which calls do_menuO. At Gl , dne 
item number bits within the Code are isolated and since Pen3 is 
a subitem of Color (which is the Item #0 in the Project menu) 
the branch is taken to G4. The routine, do_colors, isolates 
which of the 3 subitems under Color was selected, and sets the 
foreground pen color to that color register + 1 . The reason 1 is 
added is so that the foreground pen can't be set to register 0, 
which is the background color. 

The other two menus simply print one of 3 messages to 
the window, and erase the same messages (by printing spaces 
over the area). The byte PrinuMode determines which operation. 
Rather stupid, right' This program is meant to be only a 
skeleton example of using Intuition. Experiment with adding 
menus and items, and more meaningful handlers. 

"When returning back to _main from any one of the 
handlers, the code always branches back to E4 to check for any 
more messages at the pon. GetMsg only returns one message at 
a time. It is entirely possible that Inniition has "queued" several 
messages. GetMsg returns them in die order that they arrived at 
the port. When the last message is removed from the port and 
processed, the program has nothing more to do, and so tells 
Exec to "put it to sleep" with a call to Wait. The signal mask for 
the UserPort is passed to this function in dO. hi essence, the 
program is asking Exec to allow resumption only when Intuition 
puts a message to the port and signals the task. Never let a task 
go to sleep before all messages have been gotten and replied. 

The routine, print_message, uses a structure of my own 
creation. Each string has a IvisgStruct. It contains the address of 
the NULL-terminated string (LONG) and the X and Y window 
co-ordinates where the string will be printed (WORDS). Since I 
need to output one of 5 possible strings, there are 5 of these 
structures all adjacent in memory beginning at the label 
MsgStruct. I prefer to have related structures adjacent in memory 
rather than using the popular linked list approach. This prefer- 
ence is based on execution speed. With adjacent structures, 
post-increment and pre-decrement addressing modes can be 
used. Also, I only need to know the base of the first structure, 
and the size of one structure in order to locate the desired 
structure. Searching linked lists can be very time-consuming. 
Also, I try to make the size of a structure a power of 2, (i.e. 8, 
l6, 32, etc). This is so that instead of calling a multiplication 
routine to fmd the offset from structure *1, I can use left shifts 
or simple adds (as demonstrated at line K2). Arrange the 
members of the structure in the order that they need to be 
accessed so that post-increment addressing mode can be used 
(as in K3). 

The last aspect of the program is exiting it. The user exits 
by either clicking on the close gadget (which sends a 
CLOSEWINDOW message to the port) or by selecting the Quit 
item from die Project menu. Bodi actions clear the byte Quit 
which was initially set to a 1. This happens in line El6 of _main, 
and line G2 of do_menuO, respectively. Note that I don't 
immediately branch to an exit routine. This is because there 
might be more IntuiMessages queued at the port. Never exit a 
program before all messages sent to the task are replied, so that 

these messages can be freed. The point where Quit is examined 
to see if the user wishes to exit, is when GetMsg returns dO = 
(indicating no more messages). This occurs in line E5 of _main. 
If so, then the branch to El 5 is taken, and quit_all closes/ 
deAllocates everything that was opened/Allocated in exactly the 
opposite order. 

By using this example program as a starting point, you 
should be able to quickly develop a program in assembly 
language that utilizes the most unique aspects of the Amiga: 
Intuition and libraries. Later, I wtU present some examples of 
how rawkey and mouse messages might be interpreted, as well 
as adding gadgets to the window. These will be "plug-in" 
modules to replace the dummy calls, so for now, assemble the 
program and experiment with menus, fonts, and outputting text. 


If you are using the Manx Asm, disable the small code, 
small data feature. 

Execution speed is best obtained by the following: 

1) Using alll4 of the 68000's registers. 

2) Using post-increment and pre-decrement addressing 
modes instead of indexed. 

3) Passing values in registers wherever possible. 

4) Using conditional branching for loops wherever 

The Manx method of speeding up code requires the use 
of register a4, and may impose limits upon the size of the pro- 
gram. It is best to use die more conventional methods men- 
tioned above. 

If you want to eliminate all external references, the _LVO 
labels can be replaced by the hex or negative decimal absolute 
values in the chart starting on page D-5 of the RKM Exec 
manual. Since the libraries and devices are what really undergo 
changes between system software updates, this is not recom- 
mended though. 

If you do not have a start-up code and are too lazy to 
type in the example in the RKM Libraries and Devices (pg. 489), 
this program can be made to run from the CU by adding the 
following code at the beginning of of)en_libs: 

fflovea.l 4,a6 ;The base address of Exec libcary Is always 

move.l a6,_Sys3ase ;scored at address S00000004.

AmigaDOS, Assembly Language, and FileNotes 

by Dan Huth 

Accurate, descriptive file naming is one of our weapons 
in the war against infonnation overload. Unfortunately, disk 
filenames have often been limited to ridiculously short lengths: 
computer users constandy try to cram accurate file descriptions 
into as few as eight characters. But systems programmers are 
lately becoming more concerned about such things, and have 
been designing disk operating systems that allow lengthy, even 
verbose, filenames. Witness my trusty old Commodore-64 
(vintage 1983) and its generous l6-character filenames. How- 
ever, the doors to file naming verbosity didn't open for me until 
March 1986, when I became tlie proud owner of a sparkling 
new Amiga 1000 that boasted (Amigas are very proud ma- 
chines) huge thirty-character filenames. 

Thirty characters are an awful lot. For example, 
Assembler_Macros_&_Constants.i is a legal filename under 
AmigaDOS. Pretty descriptive, eh.' But there's more. For those 
situations in which even a thirt^'-character filename isn't long 
enough, AmigaDOS provides its users with the ability to append 
an eighty-character comment to any disk file via the FileNote 
command. To add a filenote to a disk file named Warm- 
FuzzyData in the UFO directory on the disk in my external 
drive, I'd use this command: 

1> FileNote DFl :UFO/WarmFuzzyDoto "Info about the warm 
fuzzy ttiings that landed in ttie backyard Ttiursday night." 

But filenotes are rather elusive creatures. The only way 
to fmd out if a directory possesses one is to list the directory 
containing that directory, using the AmigaDOS LIST command. 
To determine if an individual file possesses a fdenote, you have 
±e option of listing either that file, or 
the directory containing it. Thus, to 
read all the filenotes on a particular 
disk, the poor AmigaDOS user must 
list each direaory on that disk. For 
example, to fmd out if any of the files 
on a standard Workbench 1.2 disk 
contain filenotes, I'd use this series of 

and so on. (Fourteen more list commands would be required to 
complete my search.) As you can see, accessing a filenote isn't 
as easy as accessing a filename. (The names of all the files on 
the disk would be displayed if I used the command DIR 
Workbench 1.2: opt a.) I suspea that, because of their relative 
inaccessibility, filenotes are used less often than they should be. 
If filenotes were more accessible, people would be more 
apt to use them. Very late one night I started feeling sorry for 
the poor tilings. I decided to become a filenote partisan, and 
wrote a program diat would free all those forlorn filenotes out

there from their dark jail cells of obscurity and let them in the 
bright sunshine of prominence. In oilier words, I wroie a 
program that can search an entire disk, and display any filenotes 
it finds. 

How to use SbowFiteNotes 

The program is ShovvFilcNotes. Its I/O is like this; 

1 > ShowRleNotes Work; 


This is o test subdirectory. 


Tl^is file lias absoiutely no significance, it Is a test file only. 

Work;Source/PopToFront.a (FILE) 

From Transactor 

WorkiSource/Heoder.a (FILE) 

Skeleton for assembly language source files 

Wo;k:Source/TestForm (FILE) 

Test form for EmergencyDB 


Note that ShowFileNotes accepts a command line 
argument. Only the first argument is useful, since ShowFileNotes 
ignores anything on the command line after the first argument. 
A quoted argument is allowed, and must be used if the file or 
directory name specified contains spaces. If no argument is 
specified, then ShowFileNotes uses the current directory, so that 
the command ShowFileNotes Dfl : is equi\-alent to t!ie command 
CD Dfl: followed by ShowFileNotes. If the directory or file 
given as an argument can't be found, ShowFileNotes displays an 
error message, then exits. 

How ShowFileNotes Works 

(Note: since I need to use the phrase "file or directory " so 
often, I'm going to substitute the term "object "for that phrase in 
the remainder of this article.) 

ShowFileNotes's job is to check each object in a given 
directory and aU its subdirectories, searching for any objects that 
have filenotes specified for them. If any such objects are found, 
both the objea's name and its associated filenote are displayed 
in the AmigaDOS window. 

Filenotes are stored on the disk in the objea's file header 
block, but fortunately there's no need to actually read the file 
headers from the disk to spot objects that possess filenotes. 
Instead, we can use the DOS library functions ExamineO and 
ExNextO, which take care of the low-level disk accessing for us. 

ExamineO is a function that takes a lock and a pointer to 
a block of memory called a FilelnfoBlock (FIB) as its arguments, 
and copies information from the disk into the FIB concerning 
the object associated witli the lock. We obtain a lock by using 
the DOS library function LockO, and we receive a pointer to a 
FIB when we call the Exec library function AllocMemO. The 
assembly language code fragment below illustrates the process.

Now that we have all the relevant information about the 
object in our FIB, we can access it in this manner: 

,- — Determine whether the object Is a file or a directory

; — Get a pointer to the object's name 

lea fib_FileName |a2) ,aO .-pointer ta filename Is now in aO 

inove.l aO,dl ;now the pointer is also in dl 

The first thing we should check is fib_DirEntiyType, to 
fmd out whether the object we've obtained a lock on is a file or 
a directory. If it's a file, ShowFileNotes will look only at this file, 
and nothing else on the disk. If, however, it's a director)-, we'll 
need to look at each object in it.

We can look at each object ui a directory by calling 
ExNextO- ExNextO is designed to be called after ExamineO, but 
only if the object examined turned out to be a directory. 
ExNextO returns information in the FIB about the next entr>' in 
that directory. And, succeeding calls to ExNextO return informa- 
tion about succeeding entries in the directory, until the last entry 
in the directory is encountered. At that time ExNextO returns a 
vaJue of 0, telling us there are no more entries in this directory. 
(Actually, we can't be sure that the error resulted from reaching 
the end of the directory, unless we call tlie DOS library function 
loErrO immediately after receiving the error return value from 
ExNextO. In such a case, if loErrO returns the value 
ERROR_NO_MOKE_ENTRIES we can be sure. ShowFileNotes 
isn't this fussy; it assumes that an error return from ExNextO is 
due to a "no more entries" condition.) 

In pseudocode, the process of examining the contents of 
a director^' is as follows: 


Obtain Lock and FIB for the filing system object in question 

Call Examine [) 

( — Process data returned in FIB - ) 
If (the object is not a directory) then branch to Label2 
Call ExNext (I 
while (ExNextO didn't return zero) 

( — Process data returned in FIB — 1 

If (this directory entry is a subdirectory) then 
Save necessary register values 
Perform recursive subroutine branch to Label 1 
Restore register values 

End If 

Call SxNext 
End While 

Release Lock and deallocate FIB 
Return from subroutine 

The careful reader may have noticed that the above 
pseudo-code is general in nature; the two lines of ( — Process 
data returned in FIB — ) are where all of ShowFileNotes's 
specific code goes. Ln fact, just about any program that needs to 
examine the entries of disk directories, including nested 
subdirectories, can use the above code skeleton. I imagine 
about an hour's work would suffice to transform ShowFileNotes 
into a program displaying a disk directory a la either of the 
AmigaDOS commands DIR or LIST. 

Since the source code for ShowFileNotes is included with 
this article, you can examine it to gain further insights concern- 
ing the interaction between AmigaDOS and the assembly 
language programmer. In particular, the sections of code that 
deal with the manipulation of file and directory names may be 
of interest to you, as they illuminate the handling of deeply- 
nested directory trees: ShowFileNotes will without a gulp tell 
you that a certain file named 


has as a fdenote 

HI. Didn't think you'd find me. 

One last note: There's no error message generation in 
ShowFileNotes. This would be a worthy programming 
exercise for anyone who wants to sharpen his or her 
Amiga assembly language programming skills; it won't be 
difficult, and it will be instructive.
