I was not aware about that fact, so I downloaded the source code and indeed it
uses Fortran - interesting, I may spend some time with that stuff.
However, both IBM and GNU provide pretty advanced Fortran compilers, but it
becomes more and more hairy to deal with it. Yet, if there is a demand,
somebody would probably do that. And interfacing native z/OS files and SMF in
particular should not be that hard.
Last time I heard Fortran was gathering dust in the IBM Perth lab. It's
probably been functionally stabalized and is withering on the vine being
supported for the handful of customers that actually use it.
GNU compilers are a different story. They are cheap (free), high quality
and have be ported to most platforms. Don't hold your breath for a full
function GCC port to z/OS anytime soon. Porting glibc would take a
herculean effort. It's
been tried before by very capable people, most of them bailed.
I like Kirks solution of piping the data onto cheaper, better suited
platforms for CPU intensive numerical workloads. Even the low-end x86
servers have SIMD vector execution units making them perfectly suited to
crunching stats.

One may try to build that under z/OS USS and it should work (recently somebody

To port R to z/OS Unix you will need a Fortran compiler. Although the
base language is written in C lots of R modules are written in Fortran.

I wonder if a z/OS port of the following language would be of
interest. It might be an interesting way to get some performance
information for those of us who cannot afford SAS.

But then again, probably not, because it does not have the ability to
read SMF data built in to it. And it doesn't run on z/OS. It does run
on both Linux and Windows. But, unlike SAS on Linux/Windows, it cannot
direct read z/OS data via ftp, as best as I can see.
But in the off chance somebody is interested:
