Thank you.

I feel like Annex E Ada is a niche within a niche in programming.
That puts me in a tiny minority, even of readers at c.l.a
Moving to 64-bit with GtkAda puts me in another minority.

I hope the relatively sparse responses to the thread on this
topic just reflect that these are minority Ada topics, and not
a reaction against someone with unreasonable demands or behaviour!

The goal of the software is ambitious.  To archive live stockmarket
data.  To analyse it mathematically and make useful predictions.
To display account data on multiple screens/computers at once.
To simulate various strategies on historic data.  To integrate
multiple brokerages and information sources, with redundancy.
To place stock orders with brokers autonomously.  Last but
not least, to make a decent living out of it.  This final
step has proved to be a tough challenge, but as the software
gets stronger, the results keep improving...

Without Annex E, I would have had to devise an alternative
client-server architecture.  It would certainly have been more
complex, perhaps involving specialised libraries, web servers
or CORBA.  So it still surprises me how underused (and under
tested) it is.

Hopefully, the issues I have met with Glade will be
solved in a GNAT GPL 2007.  But I'm not relying on this.

If I go quiet for a bit, it means it's working!
