    a dummy class - only existing to provide a compatible home

    for fileIn of ST-80 classes.

    Notice: 

        this class was implemented using protocol information

        from alpha testers, from reading PD programs and 

        from the Hopkins/Horan book.

        - it may not be complete or compatible to the corresponding ST-80 class. 

        If you encounter any incompatibilities, please forward a note 

        describing the incompatibility verbal (i.e. no code) to the ST/X team.
