Meanings

  1. To calculate the differences between the characters in an enciphered text and the characters a fixed number of positions previous.
    • Turingery worked on deltaed key to produce the deltaed contribution of the chi-wheels. Turing's discovery that delta-ing would reveal information otherwise hidden was essential to the developments that followed. 2007, B. J. Copeland, “Tunny and Colossus: Breaking the Lorenz Schlüsselzusatz traffic”, in Karl de Leeuw, Jan Bergstra, editors, The History of Information Security: A Comprehensive Handbook, Amsterdam: Elsevier, →ISBN, page 458:
  2. To compare two versions of the same file in order to determine where they differ (where a programmer has made edits).
    • The primary function of this command is to delta the product version file (if it has been retrieved for edit). However, prior to deltaing the product version file, the work source tree is searched to verify that no other source files are still waiting to be deltaed. 1992, Israel Silverberg, Source File Management With SCCS, Englewood Cliffs, NJ: Prentice Hall, →ISBN, page 166:
