DEC Text Processing Utility Reference Manual

This document is the DEC Text Processing Utility (DECTPU) Reference Manual, published in April 2001 by Compaq Computer Corporation.

It serves as a reference guide for experienced programmers, detailing the elements and built-in procedures of DECTPU.

Key sections include:

• Descriptions of Built-In Procedures: An alphabetical listing and detailed explanations of DECTPU's functions, including their format, parameters, description, signaled errors, and examples (Chapters 1 and 2, spanning pages 2-1 to 2-540). Procedures are grouped by function (e.g., screen layout, cursor movement, text manipulation, pattern matching, editing context status, defining keys, multiple processing, executing programs, and DECwindows-specific functions).
• Sample DECwindows DECTPU Procedures: Appendix A provides examples of DECTPU procedures for DECwindows applications, such as creating a mouse pad, implementing EDT-style commands, handling scroll bar callbacks, and copying selected material.
• DECTPU Messages: Appendix B lists DECTPU messages with their abbreviations, full text, and severity levels.
• DECTPU Cursor Behavior: Appendix C explains how the cursor position relates to the editing point and the effects of "built-in padding" in DECTPU applications.

The manual supersedes previous versions for OpenVMS Alpha and VAX, specifically Version 3.1 for OpenVMS Version 7.2. The content has not changed since OpenVMS Version 7.1.
