RSX-11D Executive Reference Manual

The RSX-11D Executive Reference Manual is a comprehensive guide intended for programmers developing software in MACRO-11 Assembly Language for the RSX-11D multiprogramming operating system. The document details the system's architecture, including memory management, task execution control, system tables, and list structures. A significant portion of the manual is dedicated to documenting system directives, which allow user tasks to interact with the executive to perform functions such as task scheduling, inter-task communication, I/O requests, and time management. It also provides guidance on using system macros, managing significant events, handling system traps (both synchronous and asynchronous), and maintaining system integrity. Appendices provide technical specifications for directive parameter blocks and internal system structures.
