Underline and overline commands

1Function		1Control code		I
Underline	ON	(ESC)	“-“l
Underline	OFF	(ESC)	“-“0
Overline ON		, (ESC)\---I	“p”1-
f Overline OFF		1(ESC)	“‘-“O

Again, that’s simple. Let’s try it with this program:

10 ’ Demo of underlining and overlining

20 LPRINT “Demo of “;

30LPRINT CHR$(27) ;“-1”;

40LPRINT “UNDELINED”;

50LPRINT CHR$(27) ;“-O”;

60LPRI NT ‘* and ” ;

70LPRINT CHR$(27);” 1”;

80LPRINT “OVERLINED”;

90LPRINT CHR$(27) ; “-0” ;

100 LPRINT ” printing.”

It should come out like this:

Demo of UNDELINED and m printing.

In this program underline is turned on in line 30 with (ESC)

“-“l, and then off in line 50 with (ESC) “-“O. The overline is

turned on in line 70 with (ESC)“-” 1, and then off in line 90

with (ESC)“-“O. There’s a new little wrinkle in this program, though. The semicolons at the end of the lines told BASIC that those lines were to be continued. Therefore, BASIC didn’t send a carriage return and line feed at the end of those lines. We just did this to illustrate that all these control codes can be used in the middle of a line. It’s easy to underline or overline only part of a line.

H Boldface printing

Your printer has very good density when it’s just printing regularly. But sometimes you may want something to stand out from the rest of the page. This printer provides a way to do this
