Hi,

if the app is still in vfp3, multiboot with /maxmem=506.
Set sys(3050) to about a third of physical memory and be certain
to have at least the same amount of swap disk as the Maxmen of the OS.

If you are working in vfp>=5, forget about the multiboot,
but take care of sys(3050) and the swap disk.

HTH
