f . . . . Foreground (character color) specification (a number from 0 to 7)
b . . . . Background color specification (a number from 0 to 7)
Adding the color specifications to the PRINT and PRINT USING statements des-
cribed on pages 37 and 38 makes it possible to display characters in a variety of
colors. In the format above, f indicates the character foreground color, and b indi-
cates the character background color. If only the foreground color is specified, the
current background color is used for display of characters; this is done by specify-
ing the foreground color, followed by a comma.
If only the background color is specified, the current foreground color is used for
display of characters; in this case, a comma must precede the background color
specification.
(Example 1)

P R ! N T ( 7 , ) " V W X Y Z
. . . . Displays the letters "ABCDE" in
yellow against a background of light
blue.
Displays the letters " F G H I J " in yellow
against a background of green.
Displays the letter "VWXYZ" in green
against a background of white.
(Example 2) Let's try adding color to the automobile race program shown on page
46.
P R I N T C, 1 3 " H "

With ordinary PRINT statements (those without color specifications), the fore-
ground and background colors used for character display are those which have been
specified with the latest COLOR statement.
