Prograph
     
        
     
        A visual {dataflow} programming language and environment from
        the {Technical University of Halifax}.
     
        Prograph is an entirely graphical {visual programming}
        language, other than for the text of {method} names, and
        supports the program development process in a
        highly-interactive fashion.  Operation icons are connected by
        data links through which information flows.  It supports
        {object orientation} via {class}-based {data abstraction} with
        {single inheritance}.
     
        Prograph is available for the {Macintosh}, and soon for
        Windows and Unix, from {TGS Systems}.
