Program Composition Notation

Program Composition Notation (PCN) is a graphical programming language used for designing sequential and concurrent programs. Intended to be easy to understand for people who are not necessarily experienced programmers, PCN employs symbols that represent different operations in the program, and users connect these symbols by lines to show how the program operates. This flowchart-like notation can also include timing information, enabling modeling of real-time systems. PCN diagrams can be translated into code using tools or interpreted directly by runtime engines embedded in devices.
