This document is the RT-11 Programmer's Reference Manual, Version 5.1, published by Digital Equipment Corporation in July 1984.

It is a comprehensive reference guide for advanced programmers using the RT-11 operating system, specifically those working with FORTRAN-IV and MACRO-11 assembly language. The manual details the programmed requests available in the system macro library (SYSMAC.SML) and the system subroutines in the system subroutine library (SYSLIB.OBJ), providing descriptions and programming examples for their proper implementation.
