 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.
