A message stream console has output capability only; it cannot be used to enter commands. The system uses the screen to present general messages.
A console in message stream mode provides an area for presentation of messages. The messages sent to a message stream console depend on the routing codes or message levels assigned to that console. Message stream consoles can provide system monitoring capabilities in tape or disk libraries, or can assist in system security.
Deleting messages from message stream consoles:
When a console enters message stream mode, roll-deletable message deletion goes into effect automatically. (See “Defining Automatic Message Deletion” .) All messages except action messages are automatically removed from the screen.
