     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.
