 Name       : HCPDLSBK
 Description: Data Link State Block
 DSECT      : DLSBK
 Function   : This DSECT maps the definitions of state of
              the data link definition for a trace id.
 Located by : TXCCM  -> TRC
              TRCDLSBK -> DLSBK
              <DLSFWD -> DLSBK, until DLSFWD = 0>
