Dynamic debugging technique
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.
Today DDT is often used as a generic term for any debugger, and modifications of the TLA for new programs are common, "adb", "sdb", "dbx", and "gdb" for instance.
