Ada itself is farily portable. So its quite possible it will be *no*
work, just a matter of recompiling the software. But of course any OS
calls made outside the language, or compiler specific features used will
be a fair bit of work to port. And there's also the related issue of
porting from Ada 83 to Ada 95, which may come up. So the answer really
has everything with how the code in question is written and what it
does.

My suggestion would be to hook up with an Ada vendor or two and ask for
their help in this estimate. Most of them have a lot of experience with
these issues.

Failing that, you'll have to go through the source youself, looking for
unportable things, with an eye towards how much redesign will be
required to get them working on the new platform. We here on c.l.a can
certianly be of help if you have specific "Is this construct guaranteed
portable?" or "How can I accomplish this in Ada on NT?" questions.

But of course no one here is going to be able to just tell you "200
hours". :-)
