Does anyone has Ada 95 or know where I can download Ada 95?
Thank you,

Follow the links to the download from ftp://ftp.nyu.edu
or its several mirrors. Look for the version of GNAT ( =
*N*ew York University *G*nu *A*da *T*ranslator) for your
machine and OS. This is one of the Gnu compilers, utilities,
etc., is free to use, and the source code is available.
But its covered by the Free Software Foundation's famous
'copy left' (as opposed to copyright), and one can't use it
for profit without further arrangements; further if you use
the source code to create something else, that something
else becomes covered by the same copy left. It is a truly
first class compiler, and the WNT/W95 version has an
excellent IDE contributed by a user.
Also, the above web site points to extensive Ada reference
material. Good luck.

A couple of corrections. First of all, GNAT stands for nothing at this
stage, the acronym above is out of date, NYU no longer has any connection
whatever with GNAT, and we found that the "Translator" part confused
people, so the above acronym is hereby disclaimed permanently.
Second, AdaGIDE was created by Martin Carlisle with the support of
the Air Force Academy, where it is used for teaching Ada in their
courses using GNAT. ACT is working closely with Martin, and ACT
fully supports this product, it is not in the contributed software
category (which for us implies no support of any kind). The distribution
of GNAT is now integrated with the distribution of AdaGIDE>
Note that there are several other good IDE's that work with GNAT,
including GRASP, and of course EMACS with Ada mode.

If you compile your own Ada source using GNAT, you can do what you

The compiler itself is subject to the GNU copyright statement.
The runtime library has special provisions which allow you to
instantiate generics from it and bind to it without imposing any
restrictions on the resulting executable.

Well, this is good; thanks to Robert and one other who
corrected my understanding. But I read a copy of the
'copy left' some time ago with exactly this question and
a related question - can the Gnu compilers &c. be used to
create software to be distributed at all without also
distributing the whole particular Gnu package used to
create it - in mind. My understanding (incorrect - separate
arrangements needed to use for profit, correct - no need to
redistribute the whole thing) came from that reading.
The copy left is verbose, perhaps necessarily so, and
perhaps it has been reworked since I read it. I wonder if
a short 1-paragraph plain English explanation is needed to
accompany it, not in any way replacing or modifying the
full 'legal' text.

I don't think a one paragraph summary would be likely to be helpful. I
think most people understand quite clearly that the issue arises with
runtime routines only (to think that the GPL somehow covers the *output*
of the compiler makes no sense at all. Think by analogy, suppose I gave
you a GPL'ed financial program, comparable to Quicken, do you think the
fact that it was under the GPL means that you have to distribute your
checking records to the world, certainly not. The fact that the output
of a compiler is object code rather than checks makes no difference!
The only issue is the runtime, but the runtime is not under the GPL, due
to the special exception paragraph:

I find it a bit surprising that John would be confused in this way. This
is of course quite incorrect. Anyone can use GNAT to build any kind of
programs at all, proprietary, classified etc. There are no restrictions
of any kind placed on programs generated by GNAT, and the runtime is
explicitly licensed in a manner that ensures that no restrictions are
engendered by the use of this runtime.

[ Robert compared the situation to the use of other (non-compiler)
programs.]
I agree, it makes no sense from my point of view and from others' point
of
view too I say, but restricting the use of the run-time and the compiler
output is possible, and I've seen it done, darn it all.

Ahh ! So ! It's not covered. Good. Thanks.
