where: Y = number of characters in message:
Up to 20 for top display
Up to 32 for bottom display
X = number of digits that make up Y (1 or 2)
Query :DATA? Query the defined text message
Description These commands define text messages for the display. A message
can be as long as 20 characters for the top display, and up to 32
characters for the bottom display. A space is counted as a character.
Excess message characters result in an error.
An indefinite block message must be the only command in the pro-
gram message or the last command in the program message. If you
include a command after an indefinite block message (on the same
line), it will be treated as part of the message and is displayed
instead of executed.
