 There is no dedicated command for clearing the screen in Atari BASIC, this is usually done with , which PRINTs the clear screen control code (analogous to in Commodore BASIC).Atari BASIC does not include a TAB function; this can be simulated by either POKEing the cursor column position at $55 or the tab position at $C9, which has a default value of 10.The changed values will not take effect until a PRINT statement is executed.
