Presents a novel extension to the C++ programming language, allowing powerful expression of concurrency and synchronization in an object-oriented environment. The principal advantages of this extension over existing alternatives are its powerful, yet simple expression, its ease of use, and the strict parsimony of additions made to the C++ syntax. The concurrent and object-oriented capabilities of our approach make it particularly useful for facilitating the construction of complex software systems, such as communication layered protocols, control systems, graphical user interfaces, multimedia and other real-time applications
