Your first STEPS print in 12-dot spacing. Now tighten up the line

spacing by adding lines 10 and 50:

10 LPRINT CHR$(27)"@"

50 LPRINT CHR$(27)"2"

The CHR$(27)“0” of line 10 changes the usual 12-dot (l/6-inch) line

spacing to a handy variation: 9-dot (l/B-inch) spacing. Nine-dot spac-

ing is especially useful in the 9-pin Graphics Mode that we introduce

in Chapter 11.

Another convenient line spacing is 7-dot (7/72inch). To see this

one, change line 10 to:

10 LPRINT CHR$(27)"1"

Although 7-dot spacing is not suitable for text, it does allow you to

print graphics designs with no gaps. You’ll use it extensively in the

graphics programs presented later.

Variable line spacing

The FX includes the three line spacing commands shown above

mainly for convenience. Besides printing in the preset 7-, 9-, and l2-

dot spacing, the FX allows you to vary line feeds from 0 to 85 dots

worth (0/7-inch to 85/72-inch). ESCape”A”CHR$(n), where n rep-

resents n/72-inch, changes the distance that a line feed covers to n

dots.
