NIL
/nil/ 1. New Implementation of Lisp. A language intended to be the successor of MacLisp. A large Lisp, implemented mostly in VAX assembly language. A forerunner of {Common LISP}. ["NIL: A Perspective", Jon L. White, MACSYMA Users' Conf Proc, 1979]. 2. Network Implementation Language. Strom & Yemini, TJWRC, IBM. Implementation of complex networking protocols in a modular fashion. ["NIL: An Integrated Language and System for Distributed Programming", R. Strom et al, SIGPLAN Notices 18(6):73-82 (June 1983)]. 3. Empty list or False. In Lisp, the empty list (or "nil list") is u sed to represent the Boolean value False. This is possible because Lisp is not typed. True is represented by the special atom "t". 4. Spoken in reply to a question, particularly one asked using the "-P" convention it means "No". Most hackers assume this derives simply from LISP, but NIL meaning "no" was well-established among radio hams decades before LISP existed. The historical connection between early hackerdom and the ham radio world was strong enough that this may have been an influence.
