This paper presents an alternative view on propositional dis-junctive logic program: Disjunctive program = Control program + Horn program. For this we introduce a program transformation which transforms a disjunctive logic program into a Horn program and a so called control program. The control program consists of only disjunctions of new propositional atoms and controls the \execution" of the ...
