     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
     NOTES      : none
