Nick,

>Ok, I did sys(3055, 700) and then checked the return value of sys(3055). The return value still says 320 (default). I'm I doing something wrong here?\

The return value of sys(3055, 700) will be the value that exists at the time you issue the command to change the value! IOW, on a fresh startup of VFP

? sys(3055) = 320
? sys(3055,700) = 320
? sys(3055) = 700

Line two above *does* change the value, but returns the value prior to that change.
