Manual deletion of messages

Operators can manually delete messages from the screen using the CONTROL E command, the cursor, or the selector pen. If your operators need to obtain screen space quickly, they can manually delete non-action messages as follows:

Use the cursor or selector pen
Use the CONTROL E command to select groups of messages to delete

Message deletion, like command entry, can be either conversational or nonconversational. In conversational mode, the operator must verify the deletion request using the cursor, selector pen, or CONTROL E command before the system can remove the messages from the screen. When the operator performs one of these functions, the screen displays the messages to be deleted and asks for verification. The operator can then make corrections or changes, if necessary, and then press the enter key.

In nonconversational mode, the operator can use the cursor, selector pen, or CONTROL E command to manually delete messages; however, the deletion requests do not need to be verified and messages are immediately deleted when the operator performs the function. This procedure minimizes operator intervention.

Use the following keyword on the CONSOLE statement to control conversational mode for the console:

CON: Specifies whether you want conversational mode

In conversational mode where the operator must verify a deletion request, the procedure to manually delete non-action messages is as follows:

Manual deletion - operator must verify	Using a selector pen or cursor	Using the CONTROL command
If CON(Y) and either DEL=NO or DEL=R/RD is not specified	Place the pen or cursor on any part of a non-action message Press ENTER key Vertical lines appear in position 3 of the non-action message and each non-action message above it. In the instruction line, the following message appears: `IEE157E DELETION REQUESTED` Message line numbers appear on screen. CONTROL E command appears on command line indicating the request. Verify the request, make changes, if necessary, and press the ENTER key To cancel the request, perform the cancel operation (PA2).	If DEL(N), enter CONTROL D,N to display message line numbers Enter CONTROL E,line number of non-action message to delete (on CONTROL E, you can also specify a range of lines to delete, a SEG value, or F to remove all flagged messages. See z/OS MVS System Commands.) CONTROL E command appears on command line as entered Verify the request, make changes, if necessary, and press the ENTER key

In non-conversational mode, the procedure to manually delete messages is as follows:

Manual deletion - no verification	Using a selector pen or cursor	Using the CONTROL command
If CON(N)	Place the pen or cursor on any part of a non-action message Press the ENTER key The non-action message and all non-action messages above it are deleted from the screen.	Enter CONTROL D,N to display message line numbers (if DEL(N)) Enter CONTROL E,line number of non-action message to delete (on CONTROL E, you can also specify a range of lines to delete, a SEG value, or F to remove all flagged messages. See z/OS MVS System Commands.) The messages are deleted from the screen.
