Octal debugger

The octal debugger permitted the inspection of the contents of disk files by name and address, and the modification of those files. It permitted the inspection of the contents of the core of an interrupted user subprocess and the modification of that core. It also permitted the inspection of the C-list of such a user subprocess and the modification of that C-list. It permitted the examination of directories by name and the modification of those directories, as permitted by the capabilities obtained from the names. It permitted the interruption of a running subprocess by hitting certain keys on the users TTY. It also obtained control over a user's subprocess if the subprocess committed an error and did not catch the error itself.
