language An extension of standard Prolog defined by Dale A. Miller and Gopalan Nadathur in 1986, in which terms are strongly typed lambda terms. Clauses are higher orderhereditary Harrop formulas. The main novelties are universal quantification on goals and implication. The Prolog/Mali compiler compiles Lambda Prolog for the MALI abstract memory system. Teyjus (http://teyjus.cs.umn.edu/) is an implementation of Lambda Prolog. Lambda Prolog home (http://cse.psu.edu/~dale/lProlog/). Mailing list: lprolog@cs.umn.edu.
