The (ESC) "3" CHR$(n) command sets the line spacing in
increments
of 11144 inch. Change line
50
in your program so it is
like this:
50 PRINT
#l,CHR$(27) "3" CHR$(I) ;
and run the program again. Now the results will look like this:

The program works just the same as before, but the line spac-
ings are just half what they were. This is because (ESC) "3"
CHR!$(n) sets the line spacing to n/144 inch.
Table 82 shows all the line spacing commands, including sev-
eral "shortcut" commands for commonly used line spacings.
Let's take a look at the last two commands in the table, which
give a one-time line feed (or reverse line feed) of n/144 inch. The
(ESC) "J" CHR$( n command does not change the setting of the
)
line spacing, but it does cause the printer to make one line feed of
n/144 inch. Try this program to see how it works:
10 'Demo one-time line feeds.
20 LPRINT "Line number 1."
30 LPRINT "Line number 2." ;
40
'One time line feed
