 NAME       : HCPDTFBK
 DESCRIPTION: DATATRACE TRACE RECORD FORMAT BLOCK
              for traces of TYPE DATA, IO, LAN
              and PCI
 DSECT      : DTFBK
 FUNCTION   : OVERLAY FOR THE TRACE RECORDS CREATED BY CP
              FOR DATATRACE TRACES OF TYPE DATA TYPE IO
              TYPE LAN and TYPE PCI
 LOCATED BY : EVTCONBF
 CREATED BY : HCPTXW
 DELETED BY : HCPTXW
 RELOCATION CONSIDERATIONS : None
 NOTES      : DTFRLNGT IS ALSO MAPPED BY MCFRLNGT
              DTFTOD   IS ALSO MAPPED BY MCFTOD
              ANY CHANGES TO HCPDTFBK THAT AFFECTS THE
              DISPLACEMENT OR FORMAT OF THESE FIELDS MUST
              ALSO BE MADE TO HCPMCFBK AND VICA VERSA
              If the length of this block increases,
              compile HCPTSR to make sure that the change
              does not cause the trace data maximum for
              any of the trace types to become invalid.
