flush was force buffers to write disc when dos days (except novell, I was using netware.plb for novells) . But with windows environment flush useles. With VFP9 you can write buffers to disc with "flush force" like dos days.

Your "flush" usage useless with vfp6.

from vfp9 help:
FORCE
Calls the Windows API FlushFileBuffers function for all affected files but does not apply to temporary files and files opened as read-only. For more information, see the MSDN online documentation.
