Ed,
While sys(1104) appears to work, what does it do? I can't find it documented anywhere (Help, MSDN, Technet).
>Very interesting. I place the sys(1104) in my form manager class

>>>I'm hoping someone knows how to force VFP to do garbage collection.
>>>For example, on an NT machine with task manager watching the VFP memory allocated, I type:
>>>
>>>x = space(16777184) ' VFP allocates between 20-36meg of RAM
>>>x = Null
>>>Release x ' RAM stays allocated
>>>
>>>CLOSE ALL
>>>CLEAR ALL ' No luck - still allocated
>>>
>>>Is there any way to force memory allocation? SYS(3050) has
>>>no effect on this kind of memory allocation.

>>>We have a citrix box with many VFP apps running, and if one

>>>If anyone has any insites, I would be very thankful.
