I have a VFP SP3 application that uses GPLIB.FLL to issue some NetWare APIs. I am moving the app from Win95 to XP. When I issue a "set library to gplib50.fll' on XP I get a "gplib.fll is invalid" error message. The tech support on GPLIB says that it does not support XP.

What to do? Guess I could try to determine the operating system and issue the SET LIBRARY only if Win95. How can I tell the OS and are there any other suggestions?

Thanks
