You may need to change the attributes of a message that you are editing. The
new message attributes command (control A), allows you to change the
message attributes without retyping the message. The command provides a
series of prompts just like you saw when you entered a new message.
However, the defaults for the prompts now match the attributes currently in
effect for this message. You will also be given an opportunity to change the
message number. Type [Ctrl] [A]:
The default for the prompt is the current message number. Type the new
message number over the current number. Since no two messages can have
the same number, you must reassign a unique message number to the
message before pressing [Return]. If no new message number is desired, just
press return without changing the displayed message number. The DL20
searches message memory for a message with the same number. If one
exists, you will see this prompt:
followed by:
You must try again. If the message number does not exist, the message under
edit will be renumbered. The old message number then becomes free for
re-assignment.
At this point, you will now be re-prompted for the message attributes, any of
which can be changed.
During editing, messages are displayed 20 characters at a time. As noted
previously, you can move about the message, examining any part. When this
same message is displayed in Run mode, it is displayed much differently.
The message may scroll, it may flash, or it may have variable data in it. To
quickly preview a message, type [Ctrl] [R], and the message is displayed just
as it would in the run mode.
An auto repeat message will only run once, and a message with variable data
will have random data displayed. The run time simulation is as real as
possible, attached slaves and printers will work as they should and message
chains will be displayed. After the message has been displayed, the window
will be restored, with the cursor left where it was originally. When editing
your first message, use control A to try different attributes and then use
control R to display the message and see for yourself what the different
attributes do.
