Quite a bit, I would think.  COBOL is not my favorite language, but it would
be difficult not to consider it quite an advance for the times, and cost-
effective over its lifetime.  With respect to Ada, I have seen
a presentation by a fellow consultant to the effect that, once familiar with
the language, a very considerable increase in productivity is typical/possible.
(So it is not just a maintenance issue.)  The distinguishing thing about the 
presentation is that he claims to have the data to prove it -- a database of 
many (>100) projects.  My personal experience with the language (10 years) 
agrees with his assertion.
