Advanced Printing and Endless Form

1. Addition of a semicolon in line 40.

2. Closing the loop so the program can't END

and RUN.(Forget about the paper!)

(If you have to fuss, worry about Dutch

Elm disease.)

When the floor is strewn with paper and the point is made, you may hit BREAK,

and let a silent smile creep across your ugly puss. Success is sweet, eh Crock!

(CRUNCH!)

ONWARD

Suppose we're not using full 66 line forms. When's the last time you got a state-

ment on a sheet of paper that big? Oh really? And it started out "Greetings from

the President . . ."? Well, anyway.

Let's suppose we're printing on forms that are only half that size, 33 lines per

sheet. How do we set the Form Feed to automatically go to a form that isn't 66

lines long? Tho't you'd never ask. (Tho't we'd never get here!)

Escape " C " opens the Printer door for setting the form length. See Line 5:

5 L P R I N T C H R $ ( 2 7 ) " C "

C H R $ ( 3 3 ) ;

Then, C H R $ ( # # ) specifies how many lines are on the form. In this case we set it

to 33. The semicolon at the end delays the LF until the program ends. Type in

line 5:

and RUN (for several sheets)

Remarkable! All this really does work.

There's not a lot more to say about FF and LF. It's easy to let them get us into

trouble, yet so easy to avoid. If the concept is giving you problems, go back and

restudy the HOMESPUN PHILOSOPHY, and start our learning program again

from the beginning.

Horizontal Tabs

All Printer features must receive a message from the computer telling them to get

to work. Type in this simple NEW program:

10 FOR N = 0 TO 7 9

2 0

L P R I N T

T A B ( N ) ; N

3 0 NEXT N
