Slash; Large Caret - Epson FX Series User Manual

Line 40 completes the loop.
Line doesn't print anything-it just forces a carriage return at the
50
end of the print line, overriding the semicolon of line 30. Forcing the
carriage return is not really necessary since the line is the last one of
this program. It's just a good habit to develop.
Notice that the printer doesn't print each time it receives a CHR$(l).
The FX stores data in its print buffer until it receives as many numbers
as it expects-in this case, 100.

Slash

Using the form 2^X, you can fire individual pins by letting X vary
between 0 and
works. To exercise the pins in a pattern (a slash) that shows off their
placement, enter:
NEW
40
LPRINT CHR$(27)"K"CHR$(7)CHR$(0);
80 FOR X=0 TO
110 LPRINT CHR$(2^X);
120 NEXT X
When X equals 0,2^X is 1-so the bottom graphics pin is fired. When
X equals 1,2^X is 2--so the second pin is fired. This pattern continues
right up through X equals 6, which fires the seventh pin. We purposely
omit X equals 7 to accommodate systems that are limited to 7 bits.

The next step is to change the direction of the slash. Can you guess
how it's done? Sure, just reverse the order of the exponents, and the
same routine can be used. In fact, let's turn it into a subroutine:
10 F=0
40
LPRINT CHR$(27)"K"CHR$(14)CHR$(@);
50
GOSUB 80: F=l: GOSUB 80
70 LPRINT CHR$(27)"@": END
80 FOR X=0 TO
90
N=X: IF F=l THEN N=6-X
and 6 for 7-bit systems). Here's how it
