I want to make the CPU go from 0% utilization back to 100% every 10 seconds. Kind of like waves if that makes sense. I was wondering if anybody could help me since I have no clue how to do it.
You may try Address TSO "OPSWAIT 10" and some kind of busy loop.
Address TSO "OPSWAIT 10"
OPSWAIT looks like an OPS/MVS command which the OP may not have.
Here is a general routine that you can model that uses the OMVS (aka USS) sleep function:
/* rexx */ /* call USS sleep routine */ parse arg sleep_sec . say time() address 'SYSCALL' 'SLEEP ('sleep_sec')' say time() return 0
