Chapter 4
Check the printout and find where spacing is 12. Doesn’t that look more like
what we’re used to?
Now look at 24 dot spacing. Aha! It’s double spacing. By sending the high-
powered command in line 10, we can plug in our own value of S and make the
printer give us just about any spacing we want between lines (up to 85). And, we
can do it either
inside
a program or at the command level. That ought to kick the
old mind into overdrive!
Let’s LIST the program on paper to take a closer squint at it.
The line spacing stayed set where it was when we STOPped the program. That
spacing is now the new “standard,”
replacing our power-up value of 12 dots
= l/6”.
We can, however, easily shift back to the original (default) line spacing by just
sending:
PRINT CHR$ (27) “2”
Try it, then type:
LIST
Ah! Sanity has returned. Whenever we send <ESC> “2,” the spacing returns
to the “power up” value of 6 lines per inch - 12 vertical dots per line.
There are two other ways of returning the line space to its original size:
1. Use the ESC A sequence we just learned:
>PRINT CHR$ (27) “A” CHR$ (12) , or
2. Turn the printer OFF, then ON.
Turn the printer OFF, then ON, before continuing to the next topic. Remember
that this resets the Top of Form.
Caveat
Life is never as rosy as the advertisements. If it were, where would the
challenge be?
