Introduction to RSX-11M-PLUS

This document, "Introduction to RSX-11M-PLUS Version 3.0" by Digital Equipment Corporation (1985), serves as a comprehensive guide for new users to get started with the RSX-11M-PLUS operating system.

The manual covers fundamental aspects of system interaction, including:

• Getting Started: How to use various terminal types (hardcopy and video), log in, correct typing mistakes, and utilize basic commands for displaying system information (e.g., time, users) and controlling output. It introduces the Digital Command Language (DCL) as the primary interface.
• File Management: Detailed instructions on creating and editing text files using the EDT (DIGITAL Standard Editor), with explanations of cursor movement, text insertion, deletion, copying, searching, and renumbering. It also covers DCL commands for managing files (copying, deleting, displaying directories, renaming, typing contents) and the use of wildcards and qualifiers.
• Automating Commands: An introduction to indirect command files for executing sequences of commands automatically, including concepts like substitution mode and batch processing for running jobs without direct user interaction.
• System Operation: An overview of how tasks (programs) are created from source code (assembly language) through a process of assembly and linking to form executable task images. It explains how to run tasks and provides insight into the operating system's architecture, including hardware, software, real-time control, privilege, priority, file protection, and resource management (memory, CPU, devices).

The document is designed with practical examples and aims to help users understand essential jargon and the underlying operations of the complex RSX-11M-PLUS system. It also references other advanced manuals for programmers and experienced users.
