I can't remember who originally wrote it, but I came across a version of
'ed' (the standard UNIX editor, none of this visual stuff) written in
FORTRAN.

 
The first "Software Tools" book by Kernighan and Plauger was written
using "ratfor" as the example language; `ratfor` is a "rational FORTRAN"
frontend that took a semi-structured language as input and emitted
properly-formed FORTRAN code as output.
 
They implemeneted an ed-like editor in ratfor for Software Tools.  It
wouldn't surprise me if the editor you saw was that, or something
derived from it.

No, it wasn't really. I implemented the ratfor one (and all the other
tools), but the FORTRAN one I'm talking about looks pretty different.

I still have all the files for the software tools in ratfor publihed by
Lawrence Livermore Laboratory.
