  abstract= "This paper reports continuing research on language design,
     compilation and kernel support for highly dynamic concurrent
     reactive systems. The work extends the occam multiprocessing
     language, which is both sufficiently small to allow for easy
     experimentation and sufficiently powerful to yield results
     that are directly applicable to a wide range of industrial
     and commercial practice. Classical occam was designed for
     embedded systems and enforced a number of constraints * such
     as statically pre-determined memory allocation and
     concurrency limits * that were relevant to that generation
     of application and hardware technology. Most of these
     constraints have been removed in this work and a number of
     new facilities introduced (channel structures, mobile
     channels, channel ends, dynamic process creation, extended
     rendezvous and process priorities) that significantly
     broaden occam*s field of application and raise the level of
     concurrent system design directly supported. Four principles
     were set for modifications/enhancements of the language.
     They must be useful and easy to use. They must be
     semantically sound and policed (ideally, at compile-time) to
     prevent mis-use. They must have very lightweight and fast
     implementation. Finally, they must be aligned with the
     concurrency model of the original core language, must not
     damage its security and must not add (significantly) to the
     ultra-low overheads. These principles have all been
     observed. All these enhancements are available in the latest
     release (1.3.3) of KRoC, freely available (GPL/open source)
     from: http://www.cs.ukc.ac.uk/projects/ofa/kroc/."
