re: #431 SixDegrees

Most modern Fortran compilers have compiler options that allow you to turn the old behavior on - it’s off by default, and allows free-form formatting.

Where Fortran really puzzles newer programmers is in it’s treatment of arrays - their indexing is 1-based in Fortran, rather than 0-based as it is in most other languages; and two-dimensional arrays are laid out in memory in column-major order, rather than the row-major order used by Pascal, C and C++. This can easily trip up the unwary, and does take some getting used to.

I said it above and I will say it again, if the programmer is good, than the language is usable. Fortran is a solid language with many many years of being put through some very rigorous uses.
