TSTBK Prolog
NAME : HCPTSTBK
DESCRIPTION: Trace Service Tool Block
DSECT : TSTBK
FUNCTION : Contains the status of Trace Service Tools
and anchors the necessary resources when it
is active
LOCATED BY : SYSTSTBK
CREATED BY : HCPTSAVE : When the TRSAVE ON command is
first specified
DELETED BY : HCPTSEND : When the TRSAVE function is
complete
HCPTSINT : TRSAVE initialization (if error)
SERIALIZED : This control block is serialized by the
TXCLOCKC (Trace services command lock).
