It wasn't my intention to be harsh. I just think that trying to
program small examples and then post them to c.l.a in order to get
them corrected, is not the best way to learn Ada or other programming
languages. Just like there is a C++ way to do things in C++ there is
an Ada way to do things in Ada. It is important to learn the Ada way
of thinking in order to really use the language in an effective
way. Otherwise the OP will just try to write C++ programs in Ada and
think that Ada sucks because it is darn hard (and ugly) to write C++
programs in Ada.
