DDT is a family of debuggers with some common characteristics:
- Most commands are invoked with a single key, plus modifiers.
- Altmode or Escape is used as a prefix modifier.
- Arguments are commonly prefixed to the command.
DDT was first implemented at MIT for a PDP-1 computer. It was then implemented for PDP-6, 10, and 11 computers at MIT. It was also widely used at DEC.
