If you spend any time developing RPG applications you will find that, sooner or later, you will need to debug a program that runs in batch. There are a few steps that you need to take in order to do this and, because my memory is terrible, I’m putting them here.

  • Know what job queue your job is being submitted to. Hold this job queue.
  • Submit your job.
  • Your job is now sitting on the held job queue waiting to be released. Display the job and make a note of the user name, job name and number.
  • Start a service job using STRSRVJOB entering the name, job name and number from the previous step.
  • STRDBG PGM(ProgramName). You can’t enter any breakpoints yet, so hit F12 to exit the source display
  • Release the job queue
  • The Start Serviced Job screen will be displayed asking you to press F10 to enter debug commands for the job. Press F10.
  • DSPMODSRC and enter your breakpoints.
  • Press F12 to resume and F3 to return to the Start Serviced Job screen.
  • Press Enter to start your job.

The job will now begin running and will stop, passing control back to your screen, when the first breakpoint is reached.
