I thought FortranForm[] did this and inserted the necessary column-6
continuation markers. IIRC, FortranForm[expr] > myfile.f can require some
simple post-editing to comply with fortran's columnar formatting rules.

If your expression is at all complicated, it might be worth looking at 
FortranDef (Available from
www.mathsource.com/MathSource/Enhancements/Interfacing/Fortran/0202-172/FortranDef.nb)

It optimises the expression for fortran compilation and produces nicely
formatted O/P. It is intended for use (with compilation) on Unix systems but
works fine at generating a fortran O/P file under Windows.
