Memory Cleanup-- Messy structure [message #71406]

OK, here's the sequence:

IDL> STRUCT1=CREATE_STRUCT("PTR1",PTR_NEW());
IDL> STRUCTALL=REPLICATE(STRUCT1,N)
IDL> FOR I=0,N-1 DO STRUCTALL.PTR1=PTR_NEW(ALLDATA[*,I])

Then I do what I need to do, and I'm done with it, so:

IDL> UNDEFINE, STRUCTALL

Except this doesn't free the memory, according to HELP,/HEAP.

Since I'm not a real programmer, I still consider pointers to be kinda
voodoo. Can someone patiently explain how I manually clean up the
memory in this case?

Thanks,

--Edward H.
