OpenVMS Debugger Manual

This document provides comprehensive instructions and reference material for the OpenVMS Debugger. It covers both the DECwindows Motif interface (a graphical user interface for workstations) and the command interface (for terminal and workstation users).

The manual is structured into three main parts:

• Part I (DECwindows Interface): Explains how to start and end debugging sessions, use windows, menus, and views (such as source, call stack, and register views), and customize the interface. It also covers the Heap Analyzer, a feature for graphical memory visualization.
• Part II (Command Interface): Provides detailed information on starting and ending sessions, compiling and linking programs for debugging, and using commands to control execution (breakpoints, tracepoints, step units), examine and modify data (variables, registers), manage symbol searches, and customize the debugging environment.
• Part III (Debugger Command Dictionary): Acts as an alphabetical reference for all debugger commands, detailing their syntax, parameters, qualifiers, and usage examples.

Additionally, the document includes appendices covering predefined keypad functions, built-in symbols, and language-specific support (such as Ada, C, C++, BASIC, FORTRAN, and MACRO).
