To Doug Merritt:

        Modula-2 and C both exist for the Amiga.  The other "alternative"
languages you mention either do not, or are not suitable for an serious work.
Therefore I think we should constrain any discussion to these languages,
possibly adding FORTH to the list.

        I've looked at the code genrated by the M2 compilers.  The data for
vars declared as locals are referenced off the stack, much like parameters.
Not too big a hit in performance.

        I really did not intend to get into a language war.  What I expected
was to be told how to nest routines in C.  Instead I was told that it cannot
be done.

        As to your arguments about the M2 import mechanism, it is really not
such a big deal, and is certainly superior to that allowed in C.  Remember
that pre-compiled files are a non-standard part of C, whereas they are
standard in M2.  However I agree that allowing the statement

FROM Graphics           IMPORT ALL;

would be an improvement.  I believe this may be added to M2Sprints next
update, and may be added to Benchmark as well (I'll have to talk to Leon
Frenkel).

        I am switching to C so I can move to C++.  Hopefully C++ will be
a win, though I wish Eiffel were available as I'd like to check it out.


                                                        Have Fun,


                                                                Wade.
