 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 DSVBK in the system. Data collected here are
              later transferred to the processor-domain monitor
              record, MRPRCDHF.
