>I suggest you use the _shellexecute class in the FFC _environ.vcx claslib that is included with VFP6, it supports this and also parameters. FOr vfp6.exe, you would probably pass the PRG/APP/EXE file name and not a statement like DO filename.

Do this instead:
cApp='d:\foldername\prgname.prg'

Then run Shellexecute(). This will automatically cause Windows to run the cApp using VFP as long as '.prg' is a registered VFP extension.
