Abstract

An extension of PROLOG called N-PROLOG is presented. N-PROLOG allows hypothetical implications in the clauses. For clauses without implication, N-PROLOG acts like PROLOG. Examples are given to show the need for N-PROLOG. N-PROLOG is a self-reflecting language; it is equal to its own metalanguage. N-PROLOG is more suitable for expressing temporal behavior (change in time). Ordinary PROLOG is conceptually weaker than N-PROLOG.
