Guide to OpenVMS File Applications

This document, the Guide to OpenVMS File Applications, is a technical resource for application programmers and designers that provides information on using OpenVMS Record Management Services (RMS). It covers basic concepts such as file organization (sequential, relative, and indexed), disk structures (Files-11 ODS), magnetic tape formats (ANSI), performance tuning techniques (such as buffering and record management), and practical procedures for creating, populating, and maintaining files. It also details file specification components and advanced file parsing, as well as file sharing, record locking, and run-time options for managing data reliably.
