Thank you for your response, Staffan. To the best of my knowledge (and, being retired, I cannot experiment with a current release of DFSORT), there's no way I can think of to make DFSORT _not_ allocate SORTWKs for every invocation. So I had been thinking along the lines of "How can I avoid the _entire_ overhead of invoking SORT multiple times?" With or without SORTWKs, the cumulative overhead of invoking SORT (as you said) 1000's of times ... that's going to kill your performance. If there's any chance to rework the program's logic, similar to what I said in my previous post, and call SORT only once ... that's going to give you the best bang for your buck.
I hope, you can find a solution to your problem. Perhaps posting the SORT messages for one of the invocations might help shed some more light on the issue.

I wish to be able to sort records in storage without "risking" that work files are dynamically allocated. I know this may sound silly but that's not the point. The point I'm making is that the documentation for DFSORT seems to show ways to do this using various parameters such as DYNALLOC, FILESZ, etc. but I can't make it work. Many thanks for any continued input to this.
