NIL

( /nil/)

   No.  Used  in  reply  to a question, particularly one asked using the
   `-P'  convention.  Most  hackers assume this derives simply from LISP
   terminology  for  `false' (see also {T}), but NIL as a negative reply
   was  well-established  among  radio hams decades before the advent of
   LISP.  The  historical connection between early hackerdom and the ham
   radio world was strong enough that this may have been an influence.
