  DDT
       
          1. Generic term for a program that assists in debugging other
          programs by showing individual machine instructions in a
          readable symbolic form and letting the user change them.  In
          this sense the term DDT is now archaic, having been widely
          displaced by "debugger" or names of individual programs like
          "{adb", "{sdb}", "{dbx}", or "{gdb}".
       
          2. Under MIT's fabled ITS operating system, DDT (running
          under the alias HACTRN) was also used as the shell or top
          level command language used to execute other programs.
       
          3. Any one of several specific debuggers supported on early
          DEC hardware.  The DEC PDP-10 Reference Handbook (1969)
          contained a footnote on the first page of the documentation
          for DDT that illuminates the origin of the term:
       
          Historical footnote: DDT was developed at MIT for the
          PDP-1 computer in 1961.  At that time DDT stood for "DEC
          Debugging Tape".  Since then, the idea of an on-line debugging
          program has propagated throughout the computer industry.  DDT
          programs are now available for all DEC computers.  Since media
          other than tape are now frequently used, the more descriptive
          name "Dynamic Debugging Technique" has been adopted, retaining
          the DDT abbreviation.  Confusion between DDT-10 and another
          well known pesticide, dichloro-diphenyl-trichloroethane
          (C14-H9-Cl5) should be minimal since each attacks a different,
          and apparently mutually exclusive, class of bugs.
       
          (The "tape" referred to was, incidentally, not magnetic but
          paper.)  Sadly, this quotation was removed from later editions
          of the handbook after the suits took over and DEC became
          much more "businesslike".
       
          The history above is known to many old-time hackers.  But
          there's more: Peter Samson, compiler of the original TMRC
          lexicon, reports that he named "DDT" after a similar tool on
          the TX-0 computer, the direct ancestor of the PDP-1 built at
          MIT's Lincoln Lab in 1957.  The debugger on that
          ground-breaking machine (the first transistorised computer)
          rejoiced in the name FLIT (FLexowriter Interrogation Tape).

  DDT /D-D-T/ n. [from the insecticide
     para-dichloro-diphenyl-trichloroethene] 1. Generic term for a program

     instructions in a readable symbolic form and letting the user change
     them. In this sense the term DDT is now archaic, having been widely
     displaced by `debugger' or names of individual programs like `adb',

     system, DDT (running under the alias HACTRN, a six-letterism for `Hack
     Translator') was also used as the shell or top level command language
     used to execute other programs. 3. Any one of several specific DDTs
     (sense 1) supported on early DEC hardware and CP/M. The PDP-10
     Reference Handbook (1969) contained a footnote on the first page of the
     documentation for DDT that illuminates the origin of the term:
