I have converted every C++ program in the GoF Design Patterns book to
Ada95.  You can find them all in the ACM patterns archive (listed by
month of posting).

<http://www.acm.org/archives/patterns.html>


You can subscribe to the patterns list by sending the message body

subscribe patterns <your name>

to the ACM mailing list server.

Some of the early ones I did when I was learning Ada95, so you may be
better of starting from the most recent and working your way backwards.

If you have any questions, just drop me a note, or send your question to
the patterns list.
