Multitasking Object-oriented Visual Interactive Environment (MOVIE) is a system of interpreters which interpret programs written in MovieScript (extended PostScript).
The MOVIE interpreter acts like a virtual processor, executing MovieScript programs in a machine and processor independent manner.
The MOVIE network model as well as the thread model and scheduling is very similar to TCE. As a matter of fact the development of MOVIE gave foundations for developing TCE. The basic difference between MOVIE and TCE is that MOVIE is an interpreted, stand-alone system while TCE is a compiled library.
The unit of execution in MOVIE is an interpreted thread, which is a part of an interpreted tasks. Similarly to a TCE process, a task is only a passive envelope for its threads. It contains three standard ports together with other resources shared by its threads.
