This volume constitutes the proceedings of the thirdInternational Workshop on Static Analysis (WSA'93), held inPadova, Italy, in September 1993. The objective of theinternational workshop series WSA is to serve as a forum forthe discussion of the various aspects of static analysis indifferent programming paradigms. The clearly increasingmumbers of submitted papers and workshop participants pointout the growing importance of static analysis techniques forlogical, functional, concurrent and parallel languages aswell as for parallel term rewriting systems. This proceedings contains, besides the abstracts or fullpapers of the invited talks given by Pascal Van Hentenryck,Peter van Roy, and Paul Hudak, full versions of the 20contributed papers selected from a total of 68 submissionsby an international program committee consisting of manyrenown researchers in the field. The volume is organized insections on fixpoint computation, concurrency, parallelism,transformation, logic programs, term rewriting systems,strictness, reasoning about programs, and types.
