Superscript and subscript
Your LQ can also print superscripts and subscripts, which you can
use for mathematical formulas, footnotes, and other items that
require numbers or letters above or below the usual print line. ESCape
“S0” turns on superscript and ESCape
"S1"
turns on subscript. ESCape
“T” turns off either one. You can see them in action with the program
below :
10 LPRINT "The formula for water is H";
20 LPRINT CHR$(27)"S1";"2"CHR$(27)"T";
30
LPRINT "0."
40
LPRINT CHR$(27)"@"
The formula for water is H
2
O.
Now that you see how to use the ESCape sequences for superscript
and subscript, you can devise your own examples.
International characters
As you know, languages other than English require a few extra
characters. The LQ has provided for printing in many languages by
having
13
sets of international characters in its ROM (Read Only
Memory).
In order to print any of these characters, you first select one of the
following character sets and then use the individual characters within
that set.

You can select any character set with an ESCape code. In BASIC it
has the following format:
LPRINT CHR$(27)"R"CHR$(n)
