Description This code sequence redefines one of the four alternate bit image codes ESC K, ESC L, ESC Y or ESC Z as one of the bit density numbers used with the ESC * <m>... code sequence.

Available values are:

s = 75, 76, 89, 90 (ASCII = K, L, Y, Z)

n = 0

single density

n = 1

double density

n = 2

double density, high speed

n = 3

quadruple density

n = 4

screen graphics

n = 5

plot graphics (1:1)

n = 6

screen graphics II

n = 7

plot graphics, double density

n = 32

single density

n = 33

double density

n = 38

screen graphics II

n = 39

triple density

n = 40

sixfold density

For example, if you send the following code before you run a graphics program, it will change every instance of mode K (single density) to mode 3 (quadruple density):

LPRINT CHR$(27);"?K";CHR$(3);
