Pas2C64

[paul_nicholls]

Since I have added a WriteLn() command (for strings only ATM) to pas2c64, I decided to make a "hello world" example! LOL



I skipped the basic loader to save some vertical space...

It might not be the most exciting code ever, but it works <G>

hmmmmm.... nostalgia.. (remember of my C64 in faк far past ^_^)

Great, keep it going !

Hmm is that PDN in the background? 1 word man: Sweet. Not M$ paint or something paid for but open source goodness I miss very much as a native app in linux, yes Pinta and others have their benefits, but its never the same is it?

Anyway, nice work. I especially like that editor. Keep it up dude

LOL Yeah, it is Paint.NET in the background - I used it for saving the image

I have made the editor using D2010, and the TSynEdit component so I could get syntax highlighting, etc. very sweet

Thanks for the support

Cool to see someone else targeting retro hardware... I just finished a DOS game targeting a 128k 4.77mhz 8088 as the minimum spec... though I've been also working in DEFT Pascal on the TRS-80 Color Computer.

Was there no original pascal compiler for the C64 in the first place? Admittedly, a modern optimizing compiler meant for the target system would be a huge step up (just compare TP7 to TP3) but surely there must have been SOMETHING.

I mean, on the Coco we had three -- OS/9 Pascal (which sucked but is what most people used), DEFT Pascal (the only one that made standalone .bin files you could cloadm or loadm and exec while having access to all 64k of memory if present) and StarPAS (which was just a p-code interpreter)... surely there must have been something for the C=64.

Don't suppose you are planning on adding VIC=20 support to that? Just thinking I've still got one here. (along with my 64K coco 1 and my Tandy 1000EX)

Writing programs for old systems is having an interesting side effect -- at least for me... portability. Emulators are ported to pretty much every modern system, so by writing a game for an old machine, you suddenly make it available to everyone.

There is one interesting aspect of all this: if the super-optimized code designed for a few Mhz and KB could be 'adapted' (even if at a slight performance loss) to work with todays' PCs - imagine the speed you could pull out of it! XD It's like when I had to load DOS 7.1 on a quad core machine: basically DOS on steroids.

Now, that has even more potential

Neat I never had a TRS-80 computer though, only the C64 (and then 128D).

There were a bunch of Pascal compilers for the C64, but I wanted something native to windows, etc. that was easier to use

It is also a fun project + diversion for me too LOL

I hadn't thought of VIC-20 support, but maybe I will...first I will get C64 support going

Yeah! Emulators rock! On a nostalgia note, I do wish I had a real C64 though still though - it is what I learnt programming on part way between my 11th and 12 birthday

Oh well...

Hey all,
I hadn't worked on pas2c64 since February, so I thought I would have a bit more of a play with it. Since I have been using Lazarus 0.9.30 I thought I would have a go at converting over the program from Delphi to Lazarus using the automatic conversion.

It actually worked perfectly!! Everything still works, even considering I am using SynEdit as the programming GUI part...I was pleasantly surprised!!

So now I am continuing this using Lazarus now

I am also now working on converting Delphi floating point numbers to c64 floating point numbers using this site as a basis for an algorithm I am writing:

ftp://n2dvm.com/Commodore/Commie-CDs...e-base/197.htm

I have a good feeling about this, so hopefully soon I will also be able to convert floating point numbers using the parser to c64 floating point format (4-byte mantissa + 1 byte exponent, ie. compressed memory version)...

Once this works I will be able to use the C64 ROM routines to do any maths using floating point numbers!

cheers,
Paul

Great news! Still waiting release
