>What is the maximum size allowable for a prg in VFP 8 SP1?
PRGs are not limited in size - unless you count the fact that in general, VFP can't handle files above 2 GB.
The limit is for individual procedures. According to the VFP 8 help file, the "Maximum size of compiled program modules" is 64 KB. That is to say, the source code might be larger, but the compiled version is limited to 64 KB; and this limit is for every procedure, so you may well have an FXP file with a TOTAL of more than 64 KB, but less than that for every procedure.
I heard that this limitation has been removed in VFP 9. In VFP 8, you can try to split a large procedure into several procedures if you get the corresponding error messages.
