In the beginning, there was only one source form for FORTRAN (as it was then known) programs. Each statement was exactly 72 characters long - no more, no less. (See note below.) Columns 1-5 were for statement labels, whole line comments were indicated with a C in ...

Spend any time in the comp.lang.fortran newsgroup, or other places where programming languages are discussed, and you’ll soon see a new “Which is better, Fortran or C?” thread show up. These never fail to produce heated comments from people who should know better. My answer is that neither is “ ...

One of the various responsibilities I have is for the compiler samples (both Fortran and C++). For Intel Visual Fortran, we have a lot of samples - for the other compilers, fewer. The Windows Fortran samples are a mixed lot; some came to us from Microsoft Fortran Powerstation (with or without ...
