Using Control Codes - OKIDATA 120 Handbook

Here's a sample program that illustrates these statements:
10 OPEN 1,<';,0
20 PRINT#l, "THE OKIDATA 120"
3D PRINT#l, "PRINTS LIKE THIS."
<';0 CMD 1
50 PRINT "THIS PRINTS, TOO . . . "

Using control codes _______________ _
If you use a PRINT# command followed only by text, OKI-
DATA 120 gives you standard printing:
HERE'S NORMAL PRINTING
By using "control codes," you can spice up this standard
printing with headlines, underlining, and different type
sizes . You can control spacing and page length. The codes
even let you print graphics .
When the computer sends the OKI DATA 120 a control
code, the printer responds by changing one of its printing
features. Changes aren't permanent, however; they can be
canceled by sending certain other codes or by switching
the pri nter off.
When you write a program, you should insert the control
code right before you want the "special effect" to take
place. Here's an example:
10 OPEN 1,<';
20 PRINT#l,"HERE'S NORMAL PRINTING"
3D
PRINT#l, CHR$ (M) ; "DOUBLE WIDTH"
<';0 CLOSE1
HERE'S NORMAL PRINTING
DOUBLE WIDTH
