The 15 backspaces in line 40 are printed in Compressed Mode. The
difference in densities makes the second printing of Backspace be
offset from the first. You could spend all day mixing densities to get
different effects.
In the next program, the offset is not as dramatic. Change what you
have to:
3!(J LPRINT "BACKSPACES";CHR$(15); , Adds S
4!(J FOR X=l TO 17: LPRINT CHR$(8);: NEXT X
45 ' Changes 15 to 17
5!(J LPRINT CHR$(18);"BACKSPACES" , Adds S

More typically, backspace is used for single-character overstrikes.
Here are a few examples that create some useful mathematical sym-
bols:
NEW
1!(J LPRINT "="jCHR$(8)j"/" , (Not equal)
The backspace moves the print head back over the equal sign so that
the slash can be printed on top of it.

1!(J LPRINT CHR$(27)"S!(J"j"+"jCHR$(8)j , (Plus/minus)
