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 bot-
tom 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 program
message or the last command in the program message. If you include a com-
mand after an indefinite block message (on the same line), it will be treated
as part of the message and is displayed instead of executed.
