Hello,
Thank you for your answer.

Look at your code design and remember that REXX arrays are associative.
Every access to an array element is a search for the full variable name
with the index as part of the name.

It really depends on what you're doing with REXX that's causing it to munch
CPU. I associate CPU usage with slow processing, and since I'm not the perf
tune guy, I really only care about how long I have to wait for my code to
execute to completion and do so without adversely affecting others.
