A front end to gdb by Michael Golan mg@cs.princeton.edu . DUEL implements a language designed for debugging C programs. It mainly features efficient ways to select and display data items. It is normally linked into the gdb executable, but could stand alone. It interprets a subset of C in addition to its own language.
