Interface Description Language
     
        (IDL) A language designed by Nestor, Lamb and Wulf of {CMU} in
        1981 for describing the data structures passed between parts
        of an application, to provide a language-independent
        intermediate representation.
     
        It forms part of Richard Snodgrass 's
        {Scorpion} environment development system.
