CLS Keyword

CLS

Clears everything on screen - both the text display and any graphics - and moves the cursor to the top-left (0,0).

• The current foreground and background colours are not reset.
• Subsequent text and graphics draw onto a blank screen using the active colours.

Example

PRINT "Hello!"
CIRCLE 200, 150, 50, TRUE
SLEEP 1
CLS
PRINT "Screen cleared."

Notes

• CLS removes previously drawn graphics (e.g. from LINE, RECTANGLE, CIRCLE, etc.) as well as text.
• Colours set with COLOUR or BACKGROUND remain in effect after a clear.
