CLEAR

    To clear the screen, home the cursor, and clear all pending GETs.

Syntax

    CLEAR [SCREEN]

Option

    Screen: The SCREEN clause suppresses the automatic clearing of GETs
    when the screen is CLEARed.

Usage

    After CLEAR erases the screen the cursor is positioned at 0,0.

    If you are editing GETs, do not execute a CLEAR within a procedure
    invoked  either by SET KEY or the VALID clause since it will release
    all pending GETs.  To clear the screen without CLEARing GETs, use CLEAR
    SCREEN or @0,0 CLEAR.
