I didn't try it with System REXX as I don't have access to that. Let us
know how you go.

Thanks David.
Did u try this under SysremRexx? I'll try it tonight.

In the meantime you can do a quick and dirty using TCBTTIME
/* REXX */
main:
start = cputime()
do i = 1 to 1000000
nop
end
say 'CPU time:' cputime() - start
exit
cputime:
cvt = ptr(16)
tcbp = ptr(cvt)
tcb = ptr(tcbp + 4)
tcbttime = stg(tcb + 316, 8)
microsecs = x2d(substr(c2x(tcbttime),1,13))
cputime = microsecs / 1000000
return cputime
ptr: arg ptr, len
if len = '' then len = 4
return x2d(c2x(bitand(storage(d2x(ptr),len),x2c('7FFFFFF'))))
stg: arg ptr, len
return storage(d2x(ptr),len)

Maybe in System REXX but not in TSO where you may have split screens and
multiple tasks in the mix. Open an RFE.

Boys, don't still the thread... I need to understand why is same code
not
working under SystemRexx. Try it yourself.
I would take a guess that if you are running System REXX with TSO=YES
then sysvar('SYSCPU') is returning the CPU time of
the parent task and not the CPU time of task that the exec is running
in.

Can you share you compiler JCL?

David - I ran it on z/OS 2.2, the REXX compiler is 1.4
How about you?

The new test shows:
Non-compiled

Compiled

Your results are different to mine!
Interpreted: CPU time = 3.12
Compiled: CPU time = 7.99
Not so great, because of the inefficient memory management with
stem
usage?
