10.2.5 Text commands
The user can define up to 200 different items of text and their position on the screen
and display the items of text using a short command. An item of text is allowed to be
a maximum of 30 characters long.
The text definitions can be made at any time. If an item of text already defined is re-
defined, the old item of text is erased. Within a defined item of text, other LCD commands
are also allowed, thus longer command sequences can also be opened using the short
command (macro function).
If an item of text that has not yet been defined is to be output, the error byte is set to 34H.
The error byte can be polled using the status polling (section 9.1).
