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 necessary for most uses, but you can find its command (ESCape "A") 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. 52
