Underline Mode
The LX-90 also has a mode that will underline characters and
spaces. You turn it on with ESCape “-1” and off with ESCape “-0”.
Note that the underline code is like the expanded code in that it uses a
character, in this case the hyphen or minus sign, combined with nu-
meral one to turn it on and a character combined with the numeral
zero to turn it off. You can see it in action with the following program:
NEW

20 LPRINT CHR$(
