I can highy recommend to use the InterCall package by T.D. Robb (Mail
to analytic at earwax.pd.uwa.oz.au) it makes combining Fortran (or other
external) programs and  Mathematica very easy.  I use it very often
because I only have to write the numerical part (functions/integration
routines) in Fortran and do not have to bother about In/Output or
Graphics because I do this via Mathematica. Moreover it is very easy to
check the behaviour of my routines (debugging), because I can
interactively investigate the variables, plot this vs. that or check
the results against Mathematica results and so on...  To make this a
little bit more easy I could give you a m4 prepocessor script that I
wrote for myself making this task a bit more easy (saves a lot of
typing - and makes it possible to access all common-block variables)
