You needed struct(1) in v7. It did precisely that, converting Fortran
to Ratfor. Amazingly (to me, anyway) it embodied a theorem: a Fortran
program has a canonical form. People found the converted code to be
easier to understand--even when they had written the original code
themselves.

You mentioned this before
(https://minnie.tuhs.org/pipermail/tuhs/2020-March/020670.html).
Personally, I don't know why Brenda Baker isn't famous.

I ran it on a number of Fortran programs in the EE department
at the U of MD. When it *didn't* resolve loops into Ratfor
style WHILE constructs and the like, it usually meant there was
a bug. I found at least two or three bugs this way.
