Density Varieties

Although all the examples so far in this chapter have been in the

single-density graphics mode, the LX-90 offers five other eight-pin

density modes and two nine-pin ones. Nine-pin graphics is not neces-

sary for most uses, but you can find its command (ESCape “

”) in

Appendix B. All the eight-pin densities and their commands are

described in Table

8-l.

Table 8-1. Graphics modes

You are familiar with the command format that uses the ESCape

code and a letter, but LX-90 graphics commands can also be in the

following format:

LPRINT CHR$(27)"*"CHR$(m)CHR$(nl)CHR$(n2);

with m being the mode number found in the left column of Table

8-l.

As usual, nl and n2 reserve the number of columns for graphics. The

seven modes include six densities, with two speeds for double-density.
