Pascal has nice strong typing rules.  It was designed to be a good choice
as a first language (not to denigrate its power at all, but rather to
point out its singular strength).  Sadly, when I was in school at
the level where people were learning to program (not that long ago, I'm
not that old :-) ), the mindset was that people should begin with BASIC
before moving on to the advanced languages like Pascal or C or Fortran.
The fortunate among us were able to forget the mistakes we learned in BASIC
and learn to organize and structure ourselves the way Pascal required.

Pascal requires that all functions have fixed strongly-typed arguments.
Excellent idea, but even they had to admit that the real-world demands
some tradeoffs of idealism/structure vs. efficiency, and writeln() was
Pascal's sheepish concession.  Conversely, C has gone too far, though
ANSI has brought it back some.

Generally not on the Amiga.  The standard C-style calling convention
puts arguments on the stack, so you can pile them up until you blow
your stack.
