It appears that you intend to write software which is really for a one
off calculation albeit for a number of scenarios.

Modern personal computers are incredibly fast. Apparently the new Mac
G5 is on par with a Cray supercomputer from 1985.

Given how fast computers are and how slow programmers are for a one
off calculation you should be looking for a language which will be
easy to program in and which is not prone to the introduction of
errors.

If you are already familiar with Pascal then you should seriously
consider using Delphi. I have been playing around with some
computation in Delphi. I was concerned with performance so I replaced
the innermost loop (doing DAXPY) with inline assembler and got only a
small improvement even though that loop consumed a majority of the
total time for the whole program.

I do not think you will suffer much or any performance penalty using
Delphi over C or C++.
