The latter permitting specification of data types and concurrency through the use of modular algebraic specifications and structured algebraic nets based upon an object oriented approach. System specification will be demonstrated through an ascending distributed termination detection algorithm. Major aspects of the environment and the CO-OPN formalism will be discussed.Conformtext::conference output::conference proceedings::conference paper
