 Name       : PROP
 Description: PROP NODE LIST FOR COMMUNICATIONS CHECKING
 DSECT      : COMCLIST
 Function   : COMCLIST IS USED AS A TEMPLATE TO DESCRIBE AN
              ENTRY IN THE LIST OF NODES BEING CHECKED BY THE
              PROP. COMCLIST - PROP NODE-CHECKING LIST One of
              these control blocks is created for each node
              that is checked for its ability to communicate
              with the programmable operator facility. The
              programmable operator facility uses this block
              as a listing to verify which nodes have to be
              checked.
