Using the ABEND job
Use the ABEND job when you want to propagate the ABEND state to the job stream status.
If something bad occurs in your job stream and it is detected by the branch job, you can propagate this bad status at the job stream level by putting the ABEND job in the bad branch that follows the branch job.
The ABEND job issues only the command exit 1, which causes the job to ABEND, and ensures that the ABEND status is propagated to the job stream. Any previously ABENDed jobs do not propagate the ABEND status to the job stream because they have the recovery option set to Continue (this is required to allow the branch job to run).
For an example of an ABEND job, see Placing the branch job into the job stream.
