Line 30 changes the line spacing. The command (ESC) "A"
CHR$(n) changes the line spacing to n/72 of an inch. The loop that
is started in line 10 increases the value of n (the variable I in the
program) each time it is executed. So the line spacing increases as
the program continues. Line 20 just shortcuts the loop when I =
13, since BASIC won't let us send CHR$(13) without adding an
unwanted CHR$(lO) to it. Finally, the (ESC) "2" in line 60 resets
the line spacing to 6 lines per inch. This is a shortcut that is the
same as ( ESC > "A" CHR$(12).
You may wonder why they picked l/72 of an inch as the incre-
ment for the line spacing command. There's a good reason: the
dots that the printer makes are l/72 inch apart. So this means that
you can vary the line spacing in increments as fine as one dot-
unless you want finer spacing, like one half dot spacing.
The (ESC) "3" CHR$(n) command sets the line spacing in
