 DSECT NAME - SYTSCP
 FUNCTION - Map a Monitor record.
 LOCATED By -
        Through the Monitor Control Area
 REFERENCED CONTROL BLOCKS -
        MRRECHDR    Monitor Record Header
 NAME - MRSYTSCP
 DESCRIPTIVE NAME - Monitor Sample Record
                    Domain 0  - System Domain
                    Record 13 - Scheduler Activity (Per Processor)
 DESCRIPTION - Describes scheduler activities in a processor.  A
               separate record is generated for each online processor
               in the system.
 NOTES:
   - This record should be used in conjunction with record MRSYTSCG
     (Domain 0, Record 10) for a complete description of scheduler
     activities in the system.
