VAX-11/RSX-11M

This document, the "VAX-11/RSX-11M User's Guide" from August 1978, serves as a comprehensive guide for RSX-11M users transitioning to or operating within the VAX/VMS operating system.

Its primary objectives are to provide information on:

1. Using the VAX/VMS MCR command language: This includes commands that duplicate RSX-11M commands and those that provide VAX/VMS functions with an MCR-like syntax, allowing for a familiar operating environment.
2. Executing MCR indirect command files: Details how to run these files, which can contain both VAX/VMS MCR commands and directives, and can be nested.
3. Utilizing RSX-11M Version 3.1 components under VAX/VMS: This covers program development tools like MACRO-11, Editor, and the Task Builder, which run in compatibility mode.
4. Running both existing RSX-11M Version 3.1 task images and native VAX-11 images within the VAX/VMS environment, including their execution requirements and limitations.
5. Using VAX/VMS as a host system for RSX-11M/S Version 3.1 system generation.

The guide also explains fundamental VAX/VMS concepts such as processes, file specifications (including Files-11 structure levels and device mapping), logical names, and syntax rules, highlighting differences from RSX-11M. It provides detailed descriptions of all VAX/VMS MCR commands for tasks like device allocation, file manipulation, process control, and system information display. Appendices cover user privileges and resource quotas.
