HFPBK Prolog

 NAME       : HCPHFPBK
 DESCRIPTION: Monitor Processor Domain Hi-Freq Sample Data Area
 DSECT      : HFPBK
 FUNCTION   : Control block for processor-domain high-frequency
              sample data.  There is a separate HCPHFPBK for
              each processor in the system. Data collected here are
              later transferred to the processor-domain monitor
              record, MRPRCPRP.

 DELETED BY : HCPMOPTM Processor Domain High-Frequency Sample
              Termination
 REFERENCES : none
 SERIALIZED : PLSHFLCK lockword in its respective PLSBK
 RELOCATION CONSIDERATIONS : None
 COMPATIBILITY AND MIGRATION CONCERNS : none
