Buffer                                       (Assignable)

        Contains a character value which is the editing Buffer used by the
        Get object.  Get:Buffer is meaningful only when the Get object has
        input focus.  At other times, it contains NIL and any attempts to
        assign a new value are ignored.

        If (oGet:Buffer) == ""
