I'm ignorant about FORTRAN, have there been attempts to modernize it? Maybe something like coffeescript/typescript?
When you compare the current Fortran standards to its '66 version, you'll see how much progress it made.
And I hope that you can actually use it these days. Round the turn of the millennium, it was still quite common for people to use Fortran 77 because that's all that was supported or fit in the general codebase.
