Exit 59 is similar to Exit 60 because it is also run in the JES2CI address space. In this environment, this exit does not have access to JES2 private storage data areas such as the HCT and the converter PCE.

One function of this exit is to enforce installation standards. If the exit fails a job, it should set a return code of 8 in register 15 before returning to JES2.

If you decide to fail the job, issue error messages to inform the operator and the user of the reason for the failure. Any WTO issued by this exit is placed into the system message data set for the job.
