You cant ask for more portable than that (or two more different systems). we have also used gnat code interchangably on sun as well. >- Libraries for graphics-programming available. lets see on sgi and mac i have macOS [mac only], opengl, X, and Motif i have also seen mention that someone has a phigs binding. there are a couple of tools for doing bindings pretty automagically. one is free on Intermetrics home page (c2ada, see home of the brave ada programmers), the other is in beta at sgi. c2ada was used to do the bindings to x and motif as well as a microsoft NT binding. we have used the sgi tool (well tom quiggle at sgi did it for us actually) to do bindings to a gui generator called xforms (took 30 minutes to get the bindings back and they compiled and ran first time). in additon i am working with a partner who is doing the mac OS bindings and its really very straightforward to do even by hand [though we starte with the output of the sgi tool on these as well]. as to the question of commercial development our radar sim is a commercial software package that we license to vendors of flight trainers its done using gnat and our company lawyers had no trouble with the gpl nor did our first customer for the new ada95 version of our tools in austraila. best jim "An ancient eastern proverb says: I complained because I had no shoes; then I met a man who had no feet.
