IPCS user completion codes

Use this procedure if IPCS processing ends with a user completion code. The code is 4 decimal digits.

Problems in either IBM-provided IPCS code or in installation exit routines can cause IPCS to issue an abend. Do the following for most IPCS user completion codes:

Check to see if IPCS issued any messages that might provide more information about the problem. These messages have the form of BLSnnnnnc, unless they were issued from an exit routine.
Look at the following explanation of the user completion code for a description of the problem. Follow the diagnostic steps for the code.
Check for a failing installation exit routine.
- Use the IPCS TRAP subcommand to isolate problems relating to the use of exit services.
- If your installation provides exit routines, check the dump to see if one of them is identified as the failing module.
  The IPCSTOC file might contain information to help identify exits.
- If the problem appears to be in an installation exit routine, attempt to by-pass the problem by using the NOTEST keyword.
- For an additional check:
  - Remove all command options that cause installation exit routines to be invoked from the IPCS input stream.
  - Rerun IPCS. If the problem goes away, an installation exit routine probably has a logic problem.
If an installation exit routine caused the problem, use the dump data to isolate the reason for the failure. Correct the exit routine.
