If the console is not in automatic deletion mode, operators can
control whether they want the message line numbers on the console
screen. With message line numbers, they can more easily determine
the range of messages to delete using CONTROL E or CONTROL E,SEG. Consecutive numbers in positions one
and two appear for each message line, including continuation lines,
for all message area messages except status displays. A numbered message
appears as follows:
12 IEE041I THE SYSTEM LOG IS NOW ACTIVE
To request message numbering, operators use the CONTROL D,N and
CONTROL E,N commands to display and erase message numbers:
- Enter CONTROL D,N to display consecutive numbers in character
positions one and two of each message area line
- Enter CONTROL E,N to remove the message numbers from the screen
when CONTROL D,N HOLD is in effect
When the operator issues CONTROL D,N and then deletes a message
or cancels an action, the numbers are removed from the screen. To
ensure that the remaining messages are renumbered, the operator can
add the HOLD operand to the command.
Note: - Automatic message deletion (automatic mode, roll mode, or roll-deletable mode) stops message
numbering requested by the CONTROL D,N,HOLD command.
- Because a display console screen can be “burned” by the number images, it is recommended that you do not have the
messages numbered all of the time. When you are in conversational
mode and delete messages by the CONTROL command, all messages are
temporarily numbered so that you can verify that you have entered
the correct delete command.
- For very large screen sizes, only the first 99 rows
can be numbered. All rows after 99 contain AA in positions 1 and 2.
Message lines with AA in the number field cannot be deleted.
