JCL tips


Notes:

The "&" character may be used as a continuation character on the JCL screen. Note that the subsequent (continued) line(s) start in position 1 of the field - do not put the "!" character in position 1.

commenting out unwanted JCL steps -- dangerous because some "reports" also update data or perform important checks. safer to “wrap” unwanted reports in LP resets like this:

!FILE LP=$NULL
!RUN PY503
LP

Or, some JCL steps can be suppressed using common code options e.g. PYFG/PY501C/NORUN. Several clients have commented out the posting programs (PY101, PY560, GL240, GL250, GL252); the accounting department does the GL posting later using PYPARN. Some clients have adjusted the JCL so that certain programs run earlier or later in the process. Examples: PY500 - final prelist - is typically not needed right away, and hypothetically could be moved toward the end of the process. PY604 - EFT file creator -- is usually the thing you absolutely need first, so that might be moved to a little earlier in the process.(thanks Rob Ryan for this tip)
