Octal Debugging Program

This document contains the documentation and assembly listings for the Octal Debugging Program (ODP) and the Combined Debugging Package (CDP), designed for use with Digital Equipment Corporation's PDP-5, PDP-8, and PDP-8/S computers.

Key components include:

• ODP (Octal Debugging Program): An on-line debugger that allows for register examination and modification, octal dumping, binary punching, multiple simultaneous breakpoints, and program control.
• CDP (Combined Debugging Package): An extension of ODP that adds floating-point debugging capabilities, including interpretive breakpoints and single-stepping.
• Floating-Point Additions: A supplemental package for CDP to enable the examination and modification of floating-point numbers in core.

The document provides detailed usage instructions, including loading procedures, command summaries for the various modes (Machine and Floating), and considerations for binary punching. It concludes with extensive assembly code listings for the different versions of these tools (3-word and 4-word packages).
