Prograph
<language>
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}.
