/sys$common/syshlp/helplib.hlb JOB, Qualifiers, /CHARACTERISTICS  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /CHARACTERISTICS=(characteristic[,...])

    Specifies one or more characteristics required for processing
    the job. If you specify only one characteristic, you can omit
    the parentheses. Codes for characteristics are installation-
    defined. Use the SHOW QUEUE/CHARACTERISTICS command to see which
    characteristics are available on your system.

    All the characteristics specified for the job must also be
    specified for the queue that will execute the job. If not, the
    job remains pending in the queue until the queue characteristics
    are changed or the entry is deleted with the DELETE/ENTRY
    command. Users need not specify every characteristic of a queue
    with the JOB command as long as the ones they specify are a
    subset of the characteristics set for that queue. The job also
    runs if no characteristics are specified.
