Unfortunately, I'm still using Fortran95. The reason is that I still
use VMS. VMS compilers, especially the Fortran compiler, used to be the
gold standard. Now that VSI has not only taken over VMS but also
indicated major compiler updates, I hope that I can move to a newer
standard before too long. (So far, I've only run across one thing that
I need in a later standard, and there is a clumsy workaround in F95, but
of course there are probably things in the newer standards I didn't know
I needed.)
