>In order to reduce the default memory usage of my app written in VFP6 SP5, I use sys(3050) to limit the memory. (To about 1/3 the default value)
>When this is used, does it mean that regardless whatever the app is doing, the maximum memory that it can utilised is limited to what is defined by sys(3050).
>Would using this cause out of memory errors where heavy processing is involved?
>Some insights would be helpful.
