My next door neighbor, Lonny Pursell, is probably the world authority on all things GFA-BASIC, his GFA page is mostly about the ST version, but he more than anyone else would probably be able to answer any questions you have about GFA-Basic. His GFA page is : userpages.bright.net/~gfabasic/ He's messed with the Amiga version briefly via emulation, and has commented on how much of a direct port it is from the ST version, complete with most or all the bugs. ^^
