Compatibility: 6.0+ 
 Purpose: Sets the state of keyboard "NumLock".  When NumLock is OFF, the
          numeric keypad can be used as arrow keys for cursor movement.

    Uses: ■ Preset the keyboard for use with screen-oriented programs which
            use the arrow keys for cursor control.
          ■ Set up so that MultiConfig Menus will work intuitively; that
            is, so the user can use the arrow keys to move the cursor bar
            (without needing to first press the NumLock key).

  Syntax: NUMLOCK=ON or OFF


       ON sets the keyboard into Numlock mode; keys on the numeric keyboard
          will represent numbers.

      OFF runs off Numlock mode; keys on the numeric keyboard represent
          cursor-control arrows.
