I fired up three instances of VFP 9 on my windows xp machine. I started up the tasklist (Ctrl+alt+del) and switched to the processes tab. In the mem usage column I saw each VFP at 7Mb.

I issued these commands:

?SYS(3050,1,1024)
?SYS(3050,2,1024)

There was no change in the mem usage.

I want to know how to prove sys(3050) is beneficial.
