Syntax	Text.Cls
Description	The Text.Cls (clear screen) procedure is used to blank the screen to the text background color. The cursor is set to the top left (to row 1, column 1).
Details	The screen should be in a "screen" or "graphics" mode. If the screen mode has not been set, it will automatically be set to "screen" mode. See View.Set for details.
Status	Exported qualified. This means that you can only call the function by calling Text.Cls, not by calling Cls.
