OpenVMS System Services Reference Manual 2

This document is the second part of the OpenVMS System Services Reference Manual: GETUTC–Z, published in April 2001 by Compaq Computer Corporation.

It serves as a guide for system and application programmers on a set of routines used by the OpenVMS Operating System. These routines cover various functions including resource control, process communication, I/O management, and other operating system services.

A key feature highlighted is the support for OpenVMS Alpha 64-bit addressing, which allows programs to manage and access data beyond the previous 32-bit virtual address limits. The manual specifies that new or enhanced services dealing with 64-bit addresses by reference often include a "_64" suffix. This volume specifically covers system services alphabetically from $GETUTC through Z.
