I can interleave your in-between states into my GitHub sequence as a parallel
side-branch, if you wish. That will significantly help close out another loose
end that I hadn't yet fully resolved.

I reverted back from character-based to a compromise between streaming and
records - something that's also friendly to Fortran 2018.


It just so happened, that later Fortran versions also included made a story
and index file compiler - one that's similar to what I have. That will be
integrated into the GitHub sequence, as well.


Most of the issues with translation (as you'll see in the history log I kept,
in the repository) were dealing with the I/O functions - with quite a few
changes made on the Fortran side, even before translating to C. Fortran has
streaming I/O now, which helps tremendously.
