Line spacing

The CHR$(8) code turns on the graphics mode, which is discussed

in the next chapter, but this code has another use. The CHR$(8) code

also reduces the space between print lines.

For printing text you want space between the lines, but occasionally

with graphics characters you will want the space between lines elimi-

nated so that the characters can combine into larger figures. The next

program shows what we mean.

Lines 20-50 in this program use several graphics characters. To be

sure that the lines meet each other, press

SHIFT

and * at the same time

for the horizontal lines and

SHIFT

and - for the vertical lines.

As you can see from the printout, the CHR$(8) code allows you to

combine some of the graphics characters to form boxes. Without the

CHR$(8) code, the vertical lines have gaps in them, as shown in the

second printout.

The commands for the modes used in this chapter are summarized

in Appendix B.
