freeing memory in programs [message #3933]

I'm writing a Wave Widgets program that uses some big arrays (256 * 256 *
128 MRI image stacks). Some operations require temporary arrays to hold
significant chunks of this, but I don't want these arrays around full
time to choke the memory. I can't use DLEVAR as I'm not at the main
program level, so how do I free up memory? If I had assigned an array
by, say

TmpArr = MAKE_ARRAY(256,256,128, /INT)

would a subsequent use of something like TmpArr = BYTE(0) or
TmpArr = MAKE_ARRAY(1) free up the memory, or would it still be taken up
but no longer accessible?

Curiously, Pete.
