NIL
/nil/ 1. New I MPLementation of Lisp. A language intended to be the successor of MacLisp. A large Lisp, i MPLemented mostly in VAX assembly language. A forerunner of {Common LISP}. ["NIL: A Perspective", Jon L. White, MACSYMA Users' Conf Proc, 1979]. 2. Network I MPLementation Language. Strom & Yemini, TJWRC, IBM. I MPLementation of co MPLex 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 used 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 si MPLy 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.
