"Format text" input box
A string can be a maximum of 100 bytes long and consists of any combination of the
following elements:
● Characters whose ASCII equivalent is between "01H" and "FFH"
● Formatting instructions for the output of variables, similar to the print function of the C
programming language.
You can enter characters in the following ways:
● By entering the ASCII equivalent: \mn where "m = 0, ... 9, a, ... f" and "n = 0, ... 9, a, ... f"
with the following exception: "\00" is not possible.
● By typing them in on the keyboard: Here, you can enter all the characters with an ASCII
equivalent between "20H" and "7EH". Exception: If you want to output a percentage
character, you need to enter "%%" here.
● Entering selected control characters:
