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).
