I understood your question, but I do not have a good answer. I, unfortunately, see trends that I do not like. For example, I have been told that Boeing is having a lot of trouble finding subcontractors who are willing to use Ada (for commercial avionics). So they are looking at Java. The project I am currently finishing had a requirement to use C. When I asked why not allow Ada, they used the "Worried that there will not be anyone to maintain it in the future" argument. For a new project, the software Lead wanted to use Ada, but the developers talked him out of it. Is this valid "data"? No. Too small a sample. Not a scientific study. Extrapolations are generally only valid for a small delta time past the present. Roger Racine At 11:10 AM 7/29/2002 , Ed Colbert wrote: >Hi Craig > >Was my question too obscure?
