ued.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
SD-lo/l 5 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
with the tops of regular printing while subscripts print even with
the bottom of regular printing. They are frequently used to
reference footnotes, and in mathematical formulas.
Table 5-4 has the codes for using superscripts and subscripts.

Superscript and subscript commands

Mode Control code
Superscript ON
STAR < ESC > “S” 0
IBM
< ESC > “S” 0
Subscript ON
STAR <ESC > “s” 1
IBM
<ESC> ‘3” 1
Super& subscript OFF STAR <ESC> “T”
IBM
<ESC> “T”
Try this program to see them work:
10 'Demo subscripts and superscripts.
20 LPRINT "Look! " ;
34) LPRINT CHR$(27) "S" CHR$(@) ; 'Superscript on.
40 LPRINT "Superscripts " ;
50 LPRINT CHR$(27) "T" ; 'Cancel superscripts.
69) LPRINT "6 " ;
70 LPRINT CHR$(27) "S" CHR$(l) ; 'Subscripts on.
84) LPRINT "subscripts " ;
90 LPRINT CHR$(27) "T" ; 'Cancel subscripts.
108 LPRINT "on one line."
Here line 30 turns on superscripts with < ESC > “S” CHR$(O).
It’s turned off in line 50 with < ESC > “T”. Then, between
printing text, subscripts are turned on in line 70 with < ESC >
