... just because it does that in gfortran doesn't mean it's standard-conforming code.

- ams6110 10y agoWhat is the "standard" fortran compiler for scientific computing? Do a lot of people use gfortran? Or something commercial?
- greglindahl 10y agoThere is no "standard" compiler. There is a Fortran standard, and there are standard-conforming compilers and standard-conforming programs. There are popular compilers, like gfortran and the Intel compiler. My point had nothing to do with popularity. My point is that non-standard-conforming programs can have anything happen when they execute, including starting World War III (see https://www.google.com/search?q=fortran+"start+world+war" https://www.google.com/search?q=fortran+"start+world+war"), and showing output from one compiler doesn't prove anything.
