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.

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)!

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.
