When you run the program, your printout should match the one
below, showing that the two modes combine with no trouble.

A later section in this chapter explains a special ESCape code, Mas-
ter Select, which allows you to control six features with one ESCape
sequence.
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
10 LPRINT "This text is not underlined."
20 LPRINT CHR$(
30
LPRINT "This text is underlined."
100 LPRINT CHR$(27);"@"

As shown in the printout above, the underline mode is continuous,
but some word processing and other applications programs produce
an underline that leaves small gaps in the line as demonstrated in the
printout below.

If your software prints this type of underline, it is using the LX-90's
underline character (ASCII 93, not the underline mode. Because the
underline character is only five dots wide, it does not fill the spaces
between characters.
