    containing the flag. Valid values are as follows:

    PPL$M_DELETEALL    Delete all items in the specified queue whose
                       value matches work-item. By default, only the
                       first item encountered is deleted.
    PPL$M_TAILFIRST    Begin searching at the end of the queue and
                       move toward the beginning. By default, the
                       search begins at the beginning of the queue
                       and moves toward the end.
