This volume contains lectures and papers delivered at Meta92, the Third International Workshop on Metaprogramming inLogic, held in Uppsala, Sweden,June 1992. The topicscovered include foundations of metaprogramming in logic,proposals for metaprogramming languages, techniques forknowledgerepresentation and belief systems, and programtransformation and analysis in logic.Particular topics include belief revision systems,intensionaldeduction, belief systems and metaprogramming,principles of partial deduction, termination in logicprograms, semantics of the "vanilla" metainterpreter, acomplete resolution method for metaprogramming, semanticsof"demo", hierarchical metalogics, the naming relation inmetalevel systems, modules, reflective agents, compileroptimizations, metalogic and object-oriented facilities,parallel logic languages, the use of metaprogramming forlegal reasoning, representing objects and inheritance,transformation of normal programs, negation in automaticallygenerated logic programs, reordering of literals indeductive databases, abstract interpretations, andinterarguments in constraint logic programs.
