Thanks everyone for the responses. Unfortunately none of them worked.
Contrary to what RSI says, there must be a built in memory limitation
or bug in IDL. I'm running 6.0 by the way. Once IDL crashes out with
the memory error, if I type in "BYTARR(120000000)" in the command
window I get "Unable to allocate memory: to make array." Even though
I still should have about 2GB of RAM available. I'm using the /3GB
flag in XP Pro. But if I try to allocate the same amount of memory in
C using "malloc(120000000)" it works just fine. This is while IDL is
in it's crash state. So there is that much available memory available
in the system. In fact if I use "malloc(1200000000)" in C it still
works. That's 10 times the amount of memory that fails under IDL
under the same conditions.
