Fortran fixed format
pclausen opened this issue · comments
Fortran77 only supported fixed format. This course is focused on Fortran90 and free format.
We should add somewhere that fixed format is still in use for older legacy systems.

We should probably avoid "legacy" as well, older systems is descriptive enough, legacy has a not-so-well-defined use, usually. Used, but sloppily to mean quite a few things, when it comes to systems and coding. Specifically we can say "before Fortran90" if there is nothing before that that used free format.
