I don't think the phrase "..adapt only slowly to new technologies.." is really appropriate here. Most of the projects I am aware of that are using Ada are large, long term projects that have been started before Ada 95 compilers became available en masse (i.e. up to and including now**). Generally there will be some capital investment early on in the project to obtain the relevant development tools and so on (unless thhey are already available). Unless serious planning for the introduction of new technology during the lifecycle of a project has been done, the project will continue and complete using the original tools and languages. "Adapt"ing to new technology during a project lifecycle without planning it in detail would be commercial suicide. I think you'll find it's the organisation rather than the project that will adapt to new technology, and the rate that this is done depends on the typical length of project. **Note - not including GNAT, but how widely used is GNAT in large safety and mission critical systems?. >But the availability of GNAT means that tens of thousands of students around >the world are programming in Ada 95 as we converse :-) You may be right, but who knows how many people use GNAT? Also, having worked in industry in the UK for almost 10 years, I find it interesting the number of graduates in the engineering and computer science disciplines who have *never* used Ada (83 or 95)! >I would be willing to bet that the questioner in this case *was* using >Ada 95! Well, why don't we ask him! Brian Franklin, if you are still paying attention to this thread, it would be appreciated if you could let us know what version of the Ada manual you are referring to, and which compiler you are using. Let's wait and see. Best Regards John McCabe
