I have noticed that some programs contain line

SYS(3050, 1, VAL(SYS(3050, 1))*0.75)

in beginning.
This decreases the foreground memory buffer which in cases where
vfp default setting is too long.

I user opens program and works with it exclusively,
will this setting increase preformance? Or will this
increase perfomance only in cases where another program is started when vfp program is running?
