Mark,
>Is there an advantage to using modes 10-12 on disk files?
You should never use 10-12 on disk files. These unbuffered modes are intended for non-buffering devices like ports. OTOH, I don't see why it would bomb your app if you used it - it should work, just be a whole lot slower...
Wish VFP had a few extra flags for the file sharing modes
