The article Mr. Frain cites does *not* introduce a new language beyond
Concurrent C.  It simply sets out an application in order to
demonstrate Concurrent C's orthogonality to C++ and to show that the
elegant object-oriented facilities provided by C++ benefit not only
sequential programming but also parallel programming.  As a matter of
fact, the current Concurrent C compiler accepts both Concurrent C and
Concurrent C++ (the language accepted depends upon a compile-time
switch).  These issues are discussed in Gehani & Roome.  *The Concurrent
C Programming Language*.  Summit, NJ:  Silicon Press. 1989 (ISBN
#0-929306-00-7), a concise and clear description of the language.

The Concurrent C product is sold by AT&T and an AT&T VAR, ImageSoft.
