GFA v2.02 was released on an ST-Format cover disk. It can be found quite easily. The compiler was never released, but it's so old it makes binaries that are not so stable. Version 3 had a whole new compiler.
Version 2.x *.bas files can be moved to version 3.x simply by saving as ASCII from the old editor and doing a merge into the newer editor and then re-saved as *.gfa. Also my updated editor will read *.bas directly.
v2.x should really be avoided.
However, if you have an original v2.02 disk, for archival purposes, please MSA it or such and post it.
