You may wonder why they picked l/72 of an inch as the in-
crement 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 tine as one
dot-unless you want finer spacing, like one half dot spacing
(STAR mode) or one third dot spacing (IBM mode).
The < ESC > “3” CHR$(n) command sets the line spacing in
increments of 1/144inch (STARmode) or l/216 inch(IMBmode).
Change line 30 in your program so it is like this:
-
-
30 LPRINT CHR$(27) “3” CHR$(I);
-
and run the program again. Now the results will look like this:
(STAR mode)
