Communication with Alsys on this topic is cumbersome. And I don't think
we will get Adaprobe's source code easily.

The problem is that the team with enough knowledge of the system is to be
left alone, fixing other problems. That's why I'm going for the Ada-only
approach. I'm reasonably familiar with Ada.

Thanks for the information. But you're right, I don't plan to do
'real' debugging.
