A System of Communicating Residential Environments
Erik J. Sandewall, Henrik Sörensen, Claes Strömberg · 1980
The SCREEN system is an experimental tool for development and maintenance of application software. It is organized as a System of Communicating REsidential ENvironments, where each environment may be e.g. a programming environment or an end-user environment. Environments are able to send and receive modules which contain programs and data, and the maintenance of an application (throughout the software life-cycle) is performed by communicating such modules. Each programming environment may send several modules to each of several end-user environments, to account for specialized user needs, as well as updates of those modules.
