    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.
