 Syntax

     CLEAR [SCREEN] | CLS

 Arguments

     SCREEN suppresses the automatic releasing of Get objects from the
     current and visible GetList array when the screen is CLEARed.

 Description

     CLEAR is a full-screen command that erases the screen, releases pending
     GETs, and positions the cursor at row and column zero.  If the SCREEN
     clause is specified, Get objects are not released.

     CLS is a synonym for CLEAR SCREEN.

 Notes

     .  SET KEY and VALID: If you are editing GETs, executing a CLEAR
        within a SET KEY procedure or within a VALID user-defined function
        will abort the active READ when control returns.  To clear the screen
        without CLEARing GETs, use either the CLEAR SCREEN or CLS commands.
