Smalltalk-80 is a language and system developed for personal workstations. Its environment is highly interactive, but allows only one person access to a single object address space, although Smalltalk-80 machines can be interconnected with networks. Recently, several Smalltalk-80 implementations taking a distributed environment into consideration have been developed These systems, however, have the following problems: A facility for concurrent programming is weak, A synchronization mechanism is not modular, and A facility for the interpersonal environment is not provided. In this paper, we describe Distributed ConcurrentSmall-talk(DCST): a language and system for the interpersonal environment. This language is an extension of ConcurrentSmalltalk to a distributed interpersonal environment.
