Perfect! Thanks.

Can you (or anyone else) suggest a good book or online tutorial for an 
existing programmer, wanting to add Ada to his language portfolio? I 
have John Barnes "Programming in Ada 95", but I don't find his 
explanations very clear (and I couldn't find the answer to the question 
above), so if there's something better out there it might be worth me 
getting it.
