VMS Internals and Data Structures 3.3

This document is the book "VAX/VMS Internals and Data Structures" by Lawrence J. Kenah and Simon F. Bate, published by Digital Press.

The book provides a detailed explanation of the internal workings of the VAX/VMS executive. It covers:

• Data Structures: Descriptions of data structures maintained and manipulated by the VMS operating system.
• Control Mechanisms: Discussions on how control is transferred between user processes and the VMS operating system, and among its components.
• VAX Hardware Features: Explanations of VAX hardware features exploited by VMS.
• VMS Executive Components: Coverage of major executive components, system initialization, and system services.

The book is intended for system programmers and users who want to understand the VAX/VMS executive's internals, and for system managers and application designers seeking to make informed decisions for system configuration and application design. It emphasizes data structures over detailed flow diagrams and excludes a general discussion of the I/O subsystem, referring to other Digital Equipment Corporation documentation for that specific topic.
