VMS Help SET, QUEUE, Qualifiers, /CHARACTERISTICS  *Conan The Librarian (sorry for the slow response - running on an old VAX)

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

    Specifies one or more characteristics for processing jobs
    on an execution queue. If a queue does not have all the
    characteristics that have been specified for a job, the job
    remains pending. If you specify only one characteristic, you can
    omit the parentheses. Each time you specify the /CHARACTERISTICS
    qualifier, all previously set characteristics are canceled. Only
    the characteristics specified with the qualifier are established
    for the queue.

    Queue characteristics are installation specific. The
    characteristic parameter can be either a value from 0 to
    127 or a characteristic name that has been defined by the
    DEFINE/CHARACTERISTIC command.

    The /NOCHARACTERISTICS qualifier cancels any characteristics
    settings previously established for that queue.
