+[[DDT]] by that name was first created on the RLE PDP-1, but even before that the UT3 program on the TX-0 was a similar type of program.
 The history of DDT on the AI lab PDP-6 is somewhat muddled.  There first was a non-timesharing DDT; it was still in use later, mostly for booting and debugging ITS.  The timesharing DDT evolved from NTS DDT, but the latter received some updates over the years.  The most obvious link is the DECtape "@ HACTRN" file which is clearly NTS DDT ported over to make timesharing system calls rather than direct IOT instructions.  There is also the matter that HACTRN was initially envisioned by Greenblatt to be an entirely unrelated program with an interface more similar to TECO.  However, Knight's "multi procedure DDT" won out.  Most files called HACTRN are DDT, but some might be code from the other.

 ==A note about ITS program versions==
-Version numbers for ITS and related software do not work exactly like we are used to today, where a version number is associated with a release of a program whose code is fixed.  The ITS version numbers are more like file edit versions, or build numbers.  A program takes its version from the source file version.  When in use, the binary is udpated with binary patches, and those updates are also noted on the paper listing, and/or in the source file.  At some point, a fresh new binary is built from the source file, which may at that point have added one to the version, or sometimes more if intermediate edits were made.

		+	LISP on ITS is [[Maclisp]], meaning [[Project MAC]] LISP. It started as an implementation of the original LISP 1.5 to the PDP-6, initially running out of timesharing (since ITS didn't exist yet). It was called PDP-6 LISP, but slightly after it was made to run under timesharing, the name Maclisp came into use.
