It should come out like this:
In this program underline is turned on in line 20 with (ESC)
“ - ” 1, and then off in line 40 with (ESC) “ -” 0. There’s a new
aspect to this program, though. The semicolons at the end of the
first three lines told BASIC that those lines were to be con-
tinued. Therefore, BASIC didn’t send a carriage return and line
feed at the end of those lines. We just did this to illustrate that
all these control codes can be used in the middle of a line. It’s
easy to underline or italicize only part of a line.
n Superscripts and subscripts
Your printer can print in two different heights of characters.
The smaller characters are called superscripts and subscripts and
are half the height of normal characters. Superscripts print even-
ly with the tops of regular printing while subscripts print evenly
with the bottom of regular printing. They are frequently used to
reference footnotes, and in mathematical formulas.
Table 3-4 has the codes for using superscripts and subscripts.

30 LPRINT CHR$(;7)I"SO";
40 LPRINT "SUPERSCRIPTS ll;
50 LPRINT CHR$(27);"T";
60 LPRINT "& 'I;
70 LPRINT CHR$(27);"Sl";
80 LPRINT "SUBSCRIPTS ";
