Hi Greg!
What you're looking for is the print file distribution, which it looks like someone changed for each step in this multi-step job.
In jobdef, select the desired step, press F6 (Define), choose B. Report Distribution, press F6 (Define) then B. Print File Name. Then change the name, hit enter a few times, and you're done.
You can also use jobdump utility (and then jobload to reload) and change the PrtFileName parameter in the desired job step.
If you're not familiar with jobdump/jobload, the syntax is a little wonky

Thank you, Thank you, Thank you!! I didn't go far enough with my defines.
Exactly what I was looking for. Now if you could just extend the file name length to greater than 14 characters... that'd be great.
I know, way too much to ask for a system that is on it's way out.

Thanks again, John!
