     NAME       : HCPTSABK
     DESCRIPTION: TRSAVE definition block
     DSECT      : TSABK
     FUNCTION   : Contains data common to a traceid being
                  traced to DASD, by issuing the TRSAVE command
     LOCATED BY : TSTTSABK (for CP tracing) field in HCPTSTBK
                  TRCTSABK (for traceids) field in HCPTRCBK
                  TSDTSABK (Back pointer) field in HCPTSDBK
     CREATED BY : HCPTSG   : Initializes TSDBK for traceids
                  HCPTSA   : When saving DASD options on
                  TRSAVE for CP on DASD ...
     DELETED BY : HCPTSE   : When terminating the TRSAVE
                  function for CP
                  HCPTSF   : When terminating the TRSAVE
                  Function for a traceid
     SERIALIZED : This control block is serialized by the
                  TXCLOCKC (Trace services command lock).
