dead code

   Also found in: Wikipedia 0.04 sec.
(programming)dead code - (Or "infeasible path", "grunge") Any part of a program that can never be accessed because all calls to it have been removed, or because it is guarded by a control structure that provably must always transfer control somewhere else. The presence of dead code may reveal either logical errors due to alterations in the program or significant changes in the assumptions and environment of the program (see also software rot); a good compiler should report dead code so a maintainer can think about what it means. Sometimes it simply means that an *extremely* defensive programmer has inserted can't happen tests which really can't happen - yet.

Synonym grunge.
