Getting FORTRAN on the Air

This document serves as a supplement to the PDP-11 FORTRAN IV manual, detailing the procedures required to successfully integrate, load, and operate the FORTRAN system on a PDP-11 running the Disk Operating System (DOS). It covers system requirements, installation procedures from both DECtape and paper tape for various disk configurations (RF11, RK11, RC11), and includes troubleshooting notes, compiler cautions, and a comprehensive list of run-time diagnostic error codes. The manual also provides guidance on using the FORTRAN system, including compilation, assembly, and linking steps, and defines the format of FORTRAN library functions and library usage.
