        Of those three languages (VB, Ada and C++), VB is perhaps the worst
choice for an introductory course.  Sure, your statement about
infrastructure is correct, but consider the stronger infrastructure that the
students would likely develop with Ada as the introductory language.

        We don't need to start the whole argument again, but VB (and often
C++ and usually Java too) lacks some important characteristics inherent in
Ada.  These include strong enumerations, subtyping and ranging, generics,
meaningful parameter modes, tasking and a safe and elegant implementation of
pointers, to name a few.

        VB shines in how well Microsoft has integrated it into its Office
suite.  By the way, have they improved on error handling since the days of
"on error goto?"

        VB and C++ often teach introductory students bad habits.  An
instructor who exploits the best features of Ada will help ward off these
bad habits in the future.  Having this "infrastructure," the students would
be more likely to develop better applications in C++, Java, VB or whatever
when the time comes.  The converse is much less likely to happen.
