Command CLEAR SCREEN Foundation
Erases the screen, ends READ, and sets cursor to 0,0.
CLEAR [SCREEN] | CLS
The command CLEAR erases the screen. If a READ command is being executed, it is terminated and an empty array is assigned to the current GetList and PromptList arrays. After execution of the CLEAR command, the cursor is positioned at 0, 0 and the functions Row() and Col() are updated.
When the option SCREEN is specified, only the screen is erased. An active READ command is continued and the GetList array remains unchanged.
CLS can be used as an abbreviation for CLEAR SCREEN.
