Abstract: This paper presents a concurrent visual programming language based on Petri nets. Most concurrent visual programming languages address concurrency by extending a non-concurrent paradigm and representation with additional control and synchronization mechanisms and notation. It is argued here that clearer and more concise concurrent program representations are possible if the concurrency is inherent in the paradigm. The language described demonstrates that Petri nets provide such a paradigm.
Keywords: Petri nets, concurrent languages, visual languages.
