Job Monitor Loop
The job monitor loop monitors the ending statuses of the launched jobs and relaunches those that end in error if requested to do so by the user. This loop cycles through the internal job list that the job launch loop populates. In addition, it terminates jobs that run too long, if requested to do so. A job cannot be relaunched for more times than specified in the F91300 record of the job.
Like the launch loop, the job monitor loop periodically fetches the control record to see if it should end.
