The OpenVMS Delta/XDelta Debugger Manual serves as a guide for system programmers to utilize the DELTA and XDELTA debuggers on various platforms, including Alpha, VAX, and Integrity (I64) servers. The manual details:

• Debugger Functionality: Explains the distinct roles of DELTA (process-context debugging) and XDELTA (system-context debugging).
• Command Reference: Provides a comprehensive list of commands for memory manipulation, setting breakpoints, controlling program execution, and displaying system state.
• Debugging Scenarios: Covers specific techniques for kernel-mode code, installed protected images, and multiprocessor configurations.
• Platform-Specific Examples: Includes appendices for sample debugging sessions on I64, Alpha, and VAX architectures, demonstrating source listing referencing and map file interpretation.
