If a rerun is initiated and the job number is in use by another job, a new job number is supplied, and the CP/<JN> directory node is changed to reflect the new job number.

If a rerun is initiated and the PROCESSID function is used, the value returned by the function can be different for the restarted job. Refer to PROCESSID Function for more information.

When a job is restarted at some checkpoint before the last, subsequent checkpoints taken from the restarted job continue in numerical sequence from the checkpoint used for the restart. Previous higher numbered checkpoints are lost.
