Maybe I'd also emphasize the nice COM interface that allow your wrapped Fortran to be made available in your Excel macros in a snap. It happens that Fortran programmers/users tends to be poor Office users except for Excel which they master at unbelievable level... My own best low work/high user satisfaction ever is just this, wrap LOWTRAN call to make is usable from Excel, a 1/2h work and a 100+ users 2 days later !
