Fair enough, but type "limit" or "ulimit" (or ask your system folk what
the SGI version is) and see what it says.

Assuming a standardish unix setup, yes. Run "top", and watch it as you
start IDL up: this should show you memory usage changing. At the least,
this should tell you what the system memory actually is both physical

If you are using pointers and objects, then the "heap_gc" command may be of
help. It frees all the heap variables.
