Hi there,

so I just though I would contribute a bit to the wast number of
source codes lying around out there. Here is some more demo
code. It's not the hottest stuff ever made, quite simple most
of it - but you will find a fast vector-box, wildly rotating
full-screen pictures and a nifty starwars scroller. Also a
very simple (but fast and easy to expand) wolfenstein thing.
Use ESCAPE key to exit most of the stuff!

                 

I'm sorry about the quality of the code, but I have not had
much time for coding (bought my PC half a year ago) so perhaps
I'll put up some better code later...
But look out for my vector animation program for doing stuff
like "Another World" animations.

                 

If the stuff doesn't work on your computer it's probably my
fault. I really don't know why. Perhaps its some interrupt
failure or illegal opcode, but anyway, my code seems to
break on some computers. If you find the mistake please
contact me!!!

                 

It's all in Pascal - with embedded assembly stuff in it
of course. Most files come in more than one version, so
you can see how the basic stuff worked and how easy it was
to expand the routines. But I'm not one of thoses "let's
comment the whole thing"-guys, so if you really want to
have explained stuff - mail me for an explanation.

                 

Use Borland Pascal V7.0, some with DPMI some not, and with '286
code generation, and put all range/stack checking switches off.
The assembly uses 80386 opcode even though BP7.0 doesn't
actually support this. Instead I'm writing the prefixes
myself. An example: A "xor eax,eax" typically is written as
$66,$33,$C0, which is "xor ax,ax" with a DB $66 prefix. So
instead we write "DB $66; xor ax,ax" in the source code.
"DB $66" is replaced with a constant, which is more readable.
"DB LONG; xor ax,ax" and so on.

                 

If this sound really wierd, complain to Borland. Why didn't they
just have 386/486 opcodes in the assembler in the first place?
(for those of you who disagree with the "xor eax,eax" opcode I
can only say, that I'm confused too. "xor eax,eax" has two (or more)
different opcodes!!! BP7.0 and TDX generates different opcodes!!??!!)

                 

The most interesting for not-so-experienced programmers would
probably be the units, which can be used for any purpose.
PCX and ILBM loaders are allways nice to have.

                 

You can use this code in any way you like. Credit me if you
use it in a demo - I really don't care! But a little message
or an e-mail note would be nice.

                 

And by the way, I'm not a member of any demo-group and don't
really want to be - only if there is some COOL danish group out
there who needs a really lazy coder...
