RE: What PERFORM parameter in EXEC statement is meant ...
Hi
In os/390 installation the system programmer defines several performance groups which has specific performance characteristics like storage speed etc. Now each job class is associated with a default performance group. If one wants to override the default performance group associated with the class he can do it by this parameter- PERFORM value in the JOB or EXEC stmt. When used in EXEC stmt only that step will be influenced by that performance group.

The value give is normally a number; usually 01-15 with 01 being the lowest and 15 being the highest. Most installations do not allow this parm to be overriden. So don't be surprised if your job doesn't do anything.
