IDLers,
The following is a question that I sent to IDL tech support today.
Below it is the reply from IDL. Thought I'd post it to see if
anybody else had similar problems or solutions.

> program multiple times EVEN with a RETALL at the end of each run.
> Somehow, it appears that consecutive runs cause it to reserve

Alan Youngblood of RSI replies:
The circumstances you describe happen when memory becomes fragmented.
Unfortunately, there is nothing you can do except use less memory in
your application, or get more for the system to work with.
