Recursive macro expansion?!?
It wouldn't surprise me in the least if the stack limit for expanding macros
is on the order of 10 levels. But I guess I would be surprised that gpasm
doesn't give you an explicit error message about exceeding that.
It would be better to use a loop. MPASM has while/endw directives -- does
gpasm have this as well?
