Hi Jens and Daniel,
Thank you. It was exactly what I was looking for.

no, but you can redefine the output of Power[], so that it
look like a*a*a, i.e.

Format[Power[a_, n_Integer],
  FortranForm] := (HoldForm @@ {Table[a, {n}]}) /. List -> Times

After computing the terms, I use the "InputForm", and then give the results to FFC compiler. The problem is that FFC does not accept "power" function. Therefore, terms such as "a^2" must be written as "a*a". Because there are many terms in the weak form of my problem, manual conversion of power terms takes a long time (and probably is subject to errors).
