 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).
 RELOCATION CONSIDERATIONS : None
