Assuming that by "Rat4" you mean the Ratfor language, the software you want
is called "ratfor", and lives on System 3, System V, 4.1BSD, and probably
4.2BSD(?).  It takes an input language consisting of old-fortran plus some
decent control structures (if-then-else, while, C-style for(;;),...)
and handles free-format input and some other preprocessor stuff.
The output is vanilla fortran 77, assuming that the input wasn't fortran-66
dependent (e.g. one-trip do-loops, etc.).
