Analyzing RPG code

In years past there was a tool provided by IBM that allowed for analysis of
an RPG program. I seem to recall it was called "SPIES" and it allowed you
to start a job and enter the RPG program name and snapshot interval and this
tool would then record at each snapshot where an RPG program was at during
the snapshot. Then you could print a report that would show how many times
the program was at a line number during the collection period. This report
was useful in locating sections of code that where CPU or I/O intensive and
were sometimes candidates for rewrites.



I can't find this SPIES utility in the V5R4 release and I'm wondering if it
still exists hidden under the covers somewhere of if it's been replaces with
a new tool. If a commercial tool exists today that's fine too, I just need
to find a tool like this somewhere.
