numbers, and all special characters of the

GWBASIC character set. You can set the

character foreground and background colors

using the COLOR (Text) statement. This

statement also allows you to create blinking,

reverse image, invisible, highlighted, and

underscore characters.

Characters are displayed in 25 horizontal lines

line 25, lines 1 through 24 are scrolled up one
