print statement must again begin with the
alignment command, CHR$(27); CHR$(25).

Color Shading (For Experts Oniy)
The program you just did printed seven
colors, but OKIMATE isn't limited to that. By
combining dot graphics and color printing,
you can create a variety of resolutions and
hues. The secret to reproducing the colors in
our program on page 44 is a checkered graphic
pattern that combines color dots with white
spaces.
When you print this pattern in color, you get
a light shade of that particular color, since the
color you choose is mixed with white. For ex­
ample, a checkered red gives you a pink
shade. By combining light colors with other
light colors, you can create dozens of colors.
The program we've provided will give you a
printout of 26 colors. It uses three subroutines
to create solid blocks of color, checkered pat­
terns and white spaces. The data statements
in lines 4000, 4010 and 4020 list the possible
combinations of yellow, magenta and cyan us­
ing these subroutines:
