In my experience most recent versions of gfortran (at least 4.5, maybe earlier) support about as large a set of standards as anything else (with the exception of a few F2003 things, but then again, (almost) no one supports those comprehensively). Definitely all of F95 + approved extensions. Non-standard extensions (DEC, Cray Pointers pre F2003) are another matter - I don't know about those. Noam
