Sure. > Are you aware of any other Fortran compilers that don't accept -D, and > if so, what flags they *do* accept? I've come across old Fortran 77 compilers that don't do any preprocessing and thus don't accept any related flags. I don't remember details though, and I'm not aware of any currently-used ones; my experience with Fortran compilers is limited though. Cheers, Ralf
