Dynamic debugging technique

From Academic Kids

For other expansions of "DDT", see DDT (disambiguation).

Dynamic Debugging Technique, or DDT, was the name of several debugger programs originally developed for DEC hardware, originally known as DEC Debugging Tape because it was distributed on paper tape. The first version of DDT was developed at MIT for the PDP-1 computer in 1961, but newer versions on newer platforms continued to use the same name. After being ported to other vendor's platforms and changing media, the name was changed to the less DEC-centric version.

As with other DEC tools, early CP/M kept the DEC name DDT for its debugger. DDT was later superseded by SID.
