I was actively involved in translating Scratchpad from VMLISP to about a dozen different lisps, then eventually to Common Lisp. I am unaware of any Fortran code. Some of the Scratchpad code was translated from MIT's Lisp. There was a Meta language developed by Dick Jenks which was compiled first in order to create the parser. I removed the Meta language and its compiler.
The ultimate target became AKCL, Austin Kyoto Common Lisp, now GCL. I worked on the garbage collector, tail recursion, and a bunch of Common Lisp compatibility issues. I minimally, and usually second-hand behind Fred Blair, was on the Common Lisp mailing list so I was carefully evaluating the AKCL compatibility. The only possible connection to Fortran was my effort to translate the BLAS and LAPACK libraries to Common Lisp. The translation result is part of the Axiom repository and was done during the open source effort. NAG also made a connection to their Fortran libraries but that was after it left IBM. If there is a Scratchpad / Fortran connection that is a surprise to me.
