On the HomeWriter- printing modes are cancelled in three

different ways:

With a specific cancelling code, such as the CHR$(15) that you used

to cancel expanded printing.

By turning the printer off and back on.

Automatically at the end of a line. Unlike expanded, most printing

effects stay on only for one line. Therefore, you don’t have to turn

them off if you use them for one whole line.

Reverse printing

In reverse printing the letters and characters are white on a black

background instead of the usual black on a white background. The

code that turns this effect on is CHR$(18), and the one that turns it off

is CHR$(146). Enter and run the following program to see this mode

in action. Be sure to include the semicolon at the end of line 40. Again

type NEW to erase the previous program before you enter this pro-

gram.

REVERSE AND STANDARD PRINTING

The printout above shows the two ways that reverse printing is

turned off:

By the ending of a print line

By the CHR$(146) code.

The words in line 20 are in reverse printing because that effect was

turned on with CHR$(18), but the next line is standard printing

because reverse printing stays on for only one line unless it is turned

on again. The first word of the last print line is in reverse printing, but

the rest is in standard printing because reverse is turned off by

CHR$(146).
