I/O error problem running Foxpro 2.6a in newer OS:
I migrated OS from Windows XP Pro 2 to both Windows XP 3 and Windows 7 32 bit (could not solve problem on Windows 7 64 bit). Ran into the I/O error that is often reported. This issue is resolved by looking at the code generated by the screen writer that Foxpro 2.6a has available. They create a Foxplus line in the code that needs to be rem out.
m.compstat = SET("COMPATIBLE")
SET COMPATIBLE FOXPLUS
Rem out the second line only, or if you rem out both lines, see the code that refers to it in the generated code and rem those references out.
