Digital Technical Journal

This issue of the Digital Technical Journal (Volume 2, Number 3, Summer 1990) is dedicated to the DECwindows program. It covers the architectural foundations of DECwindows, which is based on the X Window System, and details how Digital Equipment Corporation enhanced this base for better performance and consistency across VMS and ULTRIX operating systems. Key papers discuss the Sample X11 server, the development of the XUI toolkit, the User Interface Language (UIL), the evolution of the X user interface style, the PEX extension for three-dimensional graphics, the integration of Display PostScript (XDPS), and practical application development using DECwindows VMS Mail. The journal also provides performance analysis of DECwindows applications over Ethernet networks and includes technical biographies of the contributing engineers.
