CLS
Statement
CLS
Clears the screen and returns the cursor t o the home position.
Home is Row 0, Column 0, or in other words, the upper left cor-
ner of the screen.
If a viewport is active, CLS clears only the active viewport. To
clear the entire screen, you must use VIEW to redefine the en-
tire screen before using CLS.
Changing the screen mode with SCREEN or changing the width
with WIDTH automatically clears the screen. You can also clear
the screen by typing [ C T R L ] [ T ]
or [CTRL)[HOME].
