Obtuse, a scripting language for migratory applications
Robert Percival Cook · 1997
This paper discusses the design and implementation of Obtuse, a scripting language for migratory applications. The paper reviews the pertinent ActiveX technology that provides the runtime object infrastructure. Then we discuss the Obtuse object model and present an overview of the language. Next, several sample programs are used to illustrate the concepts. Finally, we review some of the problems with DCOM, based on our experience. ______________________________________ Keywords: scripting language, Obtuse, migratory applications, Obliq, distributed systems ____________________________________ 1.
