Crikey! Did it really take REXX a whopping 7.7 CPU seconds to count to
ten million?

Works for me just fine. Looping ten million times and incrementing a counter
by one resulted in this:
Bgn CPU: 68.66
Bgn SRV: 2447864
End CPU: 76.36
End SRV: 2721588

[External Email]
I am trying to measure Rexx exec performance metrics. Elapse is easy
Time('R') at start exec resets the counter and the second one reports the
value. But how to measure CPU or service units? I tried SYSVAR('CPU') at
beginning of exec and at end, thinking to do the calculation myself, but both
returns the same value ... same behevior with SYSVAR('SYSSRV').
I am a good developer, but i am not fooling my self I am SO good. what is the
trick to return the service units consumed by the exec?
