#### CMSTAXE Prolog

     Name       : TSOBLKS
     Description: Terminal Attention Exit Element
     DSECT      : CMSTAXE
     Function   : CMSTAXE defines the fields used in a Terminal
                  Attention Exit Element (TAXE). The TAXE is used
                  mainly by DMSCIT for processing attention
                  interrupts. The TAXEADDR field in NUCON points
                  to CMSTAXE.
