Unfortunately, you have again demonstrated the major problem with Ada, which
is marketing and lack of communication. I hope that the Aonix Sales and
Marketing Department will hone their communication skills by explaining the
many advantages of their product to you.

>     operations that are machine specific and fall into the

> 3)  The language is too large, or too verbose, etc.  This was always

> (before they went to their assigned jobs.)  When I started I had 2 half
> days of inprocessing and started working on their systems the first day.
> The companies I've worked for (or interviewed with since then) have all
