Hi,
I am Pakrat's neighbor. He really should have written... world authority on all things GFABASIC for the Atari ST. You won't find any sites that cover all versions of GFABASIC. The people that support it only care about the version that runs on their preferred operating system. Also, in all my years with GFABASIC I have never come across a single site the supports the amiga version. It was ported way too late in its life cycle and never really caught on. It fact the ST version made it to v3.6 with over 600 commands and it ended around 1991 when GFA stopped all 68K development. They never bothered to delivered v3.6 for the amiga.
There is some guy hacking at the windows version, trying to keep it going on each new windows release. Like me he does not care about versions on other platforms.
I'm a huge GFABASIC fan, but my advise is don't use GFABASIC on the amiga. Its buggy and totally unsupported. There is no one really out there to turn to if you get stuck.
I used the original GFABASIC editor in a multitasking environment for many years (small patch), before I wrote a completely new tasking compliant editor. Also the programs made with GFABASIC can task, its only a matter of following proper programming guidelines.
