Long time before ChainQ made the Atari port of FreePascal to work again, it’s just a start but you can create some tiny programs even with GUI. Since this my compileserver also compiles Atari FreePascal and supplies a download package.
When creating the Webpage for compiling FreePascal Sources in a Browser for Amiga systems, I already had in mind also do that for the Atari guys. Just it do not fit well with Amiga because the sources are not compatible (especially GUI of course).
So I made a special version for Atari Online Compilation separated with own examples (one for console one for GEM).
Have fun to try: Atari FPC Online Compiler
And of course a little video.
P.S. Bear with me, if I’m doing something stupid here… I never used Atari before 😉
