GRAPHICS MODE
In Graphics Mode you can draw complex pic-
tures as well as display text. To display text in
Graphics Mode you can use all the statements,
commands and functions available in Text
Mode, with the exception of the COLOR (Text)
and LOCATE (Text) statements. In Graphics
Mode you have to use the COLOR (Graphics)
and LOCATE (Graphics) statements instead.
Note also that the CLS and WIDTH statements
have different features in Graphics Mode.
In Graphics Mode all points of the screen are
addressable in medium, high or super resolution.
A point on the screen is called a 'pixel' (a con-
traction of "picture element"), and a line of
pixels is called a "scanline."
To print pictures that you have generated in the
Graphics Mode, you must run the MS-DOS
GRAPHICS command before running the
BASIC program that draws the pictures. See
the User Guide to MS-DOS for details.
