Abstract
An Interface has been devised for use on the PDP-10 computer that allows FORTRAN (or FORTRAN-compatible MACRO) subroutines and functions to be run under the LISP operating system (specifically, the LISP written at Stanford University, and described in Stanford Artificial Intelligence Project Note SAILON 28, by Lynn Quam). A considerable effort has been made to endow the interface with generality and ease of use, as much as could be achieved without tampering with the FORTRAN and LISP operating systems and compilers.
