The OpenVMS Internals and Data Structure book explains how the OpenVMS
executive works. It is a book for consultants, system programmers, system
analysts, system managers, application designers, and other users who wish
to understand OpenVMS's components, mechanisms, and data structures.
The book covers the operating system kernel: process management;
memory management; the I/O subsystem; and the mechanisms that transfer
control to, from, and among these. It gives an overview of a particular
area of the system, followed by descriptions of the data structures related to
that area and details of the code that implements the area.
