Yes, but they are totally isolated platforms, and everything (software 
and hardware) on it has been certified at the time of the development.

They have now to garanty a maintenance in operational condition. Reverse 
engineering on VAX CPU board, validation of parts are the major work. 
And garantying some people will know the environment for at least 10 
more years. Not any development. Even not any patch authorized in the 
production envoronments.

The heart of the software application is in Dec Ada, and it is forbiden 
to do any evolutions. There are C developments just to play with the 
environment when it has to be evaluated, and to allow new young people 
to play with it.

Perhaps I'll try DEC C and also help them to compare VAX C, DEC C and 
new possibilities a little bit later.
