The backspace function works in all pitches, which opens up some
interesting possibilities. To see what happens when you mix backspac-
ing with different pitch modes, we’ve prepared a special program that
shows off the backspace function in two passes: first in Pica and then
in Expanded Pica. We cause all backspacing to be done in Compressed
Mode to create a slight offset. Enter:
NEW
10 FOR J=0 TO 1

FOR X=1 TO 17: LPRINT CHR$(8);: NEXT X
50 LPRINT CHR$(18)"BACKSPACES" ' Compressed off
60 NEXT J: LPRINT CHR$(27)"@" ' Reset
