Use a job to debug another job

You may want to use a separate job to debug programs running in another job.

• Debug batch jobs submitted to a job queue
  Using a separate job to debug another batch job submitted to the job queue allows you to put the batch job into debug mode and to set breakpoints and traces before the job starts to process.
• Debug batch jobs not started from job queues
  You can sometimes debug batch jobs that are started on the system but which are not submitted to a job queue.
• Debug a running job
  You can debug a job that is already running if you know what statements the job will run.
• Debug another interactive job
  You can debug a job from another display, whether the job is running or waiting at a menu or command entry display.
• Considerations when debugging one job from another job
  Although most jobs can be debugged from another job, there are some considerations you should follow.
