Table 11-1. Graphics Modes

		Alternate	Description
Mode Density		code
0	Single	CHR$(27)“K”	60 dots per inch;
			480 dots per 8” line
			816 dots per 13.6” line
1	Low-Speed	CHR$(27)“L”	120 dots per inch;
	Double		960 dots per 8” line
			1632 dots per 13.6”line
	High-Speed	CHR$(27)“Y”	Same density as
2	Double		Mode 1, but faster.
			The printer does not
			print consecutive dots
			in any one row.
	Quadruple	CHR$(27)“Z” 240 dots per inch;
3			1920 dots per 8” line;
			3264 dots per 13.6”line
			The printer does not
			print consecutive dots
			in any one row.
	Epson	none	Matches the screen
	QX-10		density of the QX-10:
4			80 dots per inch;
			640 dots per 8” iine;
			1088 dots per 13.6” line.
			(This makes it easv to

the mode number a variable, M. As M varied, so did the graphics density. It was your use of the ”*" command that allowed you to use the variable.

Suppose you had used the ”K” command instead. You could use the reassigning code to make it work as though it were ”*". To see this work, enter the following lines for your current program:
