 DSECT NAME - PRCPRP
 FUNCTION - Map a Monitor record.

        Through the Monitor Control Area
 REFERENCED CONTROL BLOCKS -
        MRRECHDR    Monitor Record Header
 NAME - MRPRCPRP
 DESCRIPTIVE NAME - Monitor Sample Record
                    Domain 5 - Processor Domain
                    Record 3 - Processor Data (Per Processor)

                                                was stolen. This array does not
                                                include the master-only
                                                processor since its work cannot
                                                be dispatched by another

                                                the number of times a different

                                                user was examined to see if it
                                                should continue to run, and was
                                                selected to run again (no

                                                had to be moved to the master
                                                processor for master-only work.
                                                This is the only time work will
