The /JOB qualifier uses the value of the job name field to select
    records for processing. This field is present in all records
    except file backward link and file forward link records. For
    records that contain information about print and batch jobs, it
    contains the name of the job.

    The /JOB qualifier selects only records that have the specified
    values in the job name field. If you precede the values with
    a minus sign, it selects all records except those with the
    specified values.

    See also the /QUEUE and /ENTRY qualifiers, which select or reject
    records for print and batch jobs with specified queue names and
    queue entry numbers.
