Description

   The /PRIORITY qualifier uses the value of the priority field
   to select records for processing. This field is present in all
   records except file backward link and file forward link records.
   For print and batch job records, this field contains the priority
   of the job in the print or batch queue. For other records, it
   contains the base process priority.

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

   Each priority must be a decimal number.
