You're laboring under a few misperceptions about
ObjectAda. Allow me to clarify...

As currently implemented, any ObjectAda user can join the
mailing list simply sending an email to majordomo@aonix.com,
with the following text in the body of the message:
subscribe Intel-ObjectAda <your-email-address>
As far as the 30 day support period goes, if you just sent
in the card and can't wait for it to show up at Aonix, just
explain that to the humans answering the customer support
lines. You'll find them quite reasonable about this.

This is part of the language standard (Generic_Elementary_Functions
in the Numerics package). Given that ObjectAda is a validated
Ada 95 compiler, you'll find this package is supported.

Yep. You need to learn about Win32.
There is nothing that you can do with the GUI Builder
that you can't do without it - it's just harder. Although
the GUI Builder allows you to graphically depict your GUI,
once you press the Save button it generates Ada code with
Win32 calls. Therefore, you could certainly write the
same code yourself.
In the base products, a publicly available Win23 binding,
win32ada, is supplied on the CD along with a number of
substantial GUI examples. You'll find them in the
samples folder.
The win32ada binding set covers the full Win32 up
to NT 3.5.
In addition, an enhanced binding which provides coverage
to NT 4.x is available with the OpenPack, as are a set
of graphics libraries, and a binding to a substantial
subset of MFC.
(Beyond all this, you could use other C/ C++ APIs as
well, so long as you're willing to make bindings for
whichever calls you want to make. In general, anything
that you can program in MSVC, you can also program with
ObjectAda.)

I highly recommend that you stop by your local bookstore
and pick up one of the many books on Win32. You'd be
surprised at the breadth of stuff covered by that API.
For a quick search, the Microsoft Win32 help file is
supplied with ObjectAda. To search it or index on it,
launch it directly from the Microsoft Explorer rather
than from the ObjectAda help system. This is an
extremely valuable tool, however I recommend it only
as a quick reference. To get a better grasp of context,
you should pick out a good Win32 book.
I hope this helps.

Of course ObjectAda personal supports these functions. they are included in
Annex A of Ada 95. Check out Ada.Numerics.Generic_Elementary_Functions.

Look in the ObjectAda subdirectories under examples. You will find some
reference to Petzold. These are Ada implementations of the examples from
Charles Petzold's book Programming Windows.
Best of luck,

Actually, this is required by the language, to find the proper package,
look it up in the on-line Reference Manual that comes with OA.

This has nothing to do with Ada but with Windows programming.
The Windows API (Win32) itself is documented in the online documentation
(Help, Win32). To learn how to program Windows application you need to
learn this from some Windows programming book, e.g. Petzold.
