COMCLIST Prolog
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.
