"
    This is a pure mimicri class.
    It is not used by ST/X, but provided to support limited
    compatibility for applications which build up codetrees,
    knowing internals of ST-80's compiler class hierarchy.
    This classes protocol is not (not meant to be) fully covering
    the corresponding ST-80's classes protocol. It maps ST-80 messages
    to corresponding ST/X messages (as far as possible).

    NO WARRANTY and GUARANTEE; this class may be removed without notice.
