PDP-11 FORTRAN-77/RT-11

This document provides instructions on how to create, link, and execute FORTRAN-77 programs on PDP-11 processors running the RT-11 operating system. It details the compilation process, linker options, input/output conventions, and the run-time environment. It also discusses programming considerations, character data manipulation, and the use of the Object Time System (OTS). Additionally, it includes information on system subroutines, compatibility with older FORTRAN versions, and extensions to the ANSI standard, along with diagnostic message references.
