 NAME       : HCPHFUBK
 DESCRIPTION: Monitor User Domain Hi-Frequency Sample Data Area
 DSECT      : HFUBK
 FUNCTION   : Control block for user-domain high-frequencye function
              data.  There is a separate HCPHFUBK for each
              VMDBK being sampled. Data collected here are later
              transferred to the user-domain monitor records, MRUSEINT
              and MRUSEITE.
 LOCATED BY : VMDHFDAT
 CREATED BY : HCPMOUGT - Allocate HCPHFUBK for the user VMDBK
 DELETED BY : HCPMOURL - Release HCPHFUBK to free storage
 REFERENCES : none
 SERIALIZED : VMDHFLCK lockword in the respective VMDBK VMDHFDAT
 RELOCATION CONSIDERATIONS : None
 COMPATIBILITY AND MIGRATION CONCERNS : none
