This paper presents an object-oriented approach for building distributed systems. An example taken from the field of computer integrated manufacturing systems is taken as a guideline. According to this approach a system is built up through three steps: control and synchronization…
Pi is a debugger written in C + +. This paper explains how object-oriented programming in C + + has influenced Pi's evolution. The motivation for object-oriented programming was to experiment with a browser-like graphical user interface. The first unforeseen benefit was in the sy…
We introduce a notation for diagramming the message sending dialogue that takes place between objects participating in an object-oriented computation. Our representation takes a global point of view which emphasizes the collaboration between objects implementing the behavior of i…

This paper describes the design of a distributed object manager which allows several Smalltalk-80 systems to share objects over a local-area network. This object manager is based on the following principles: location transparency and uniform object naming, unique object represent…
This paper discusses an object-oriented interface from the Smalltalk-80™ programming environment to a Unix-like operating system. This interface imposes an object-oriented paradigm on operating system facilities. We discuss some of the higher order abstractions that were created …
This paper presents an experience with a programming language SPOOL which is based on the combination of object-oriented programming and logic programming. This language inherits the capability of knowledge base organization from object-oriented programming and its expressive pow…
Certain situations arise in programming that lead to multiply polymorphic expressions, that is, expressions in which several terms may each be of variable type. In such situations, conventional object-oriented programming practice breaks down, leading to code which is not properl…
Orient84/K is an object oriented concurrent programming language for describing knowledge systems. In Orient84/K, an object is composed of the behavior part, the knowledge-base part, and the monitor part, in order to provide object-oriented, logic-based, demon-oriented, and concu…
We used an object-oriented design to build a large scientific application: simulation of radiation therapy treatments for cancer. We provide features familiar in the graphics workstation world, including graphic editing of the proposed treatment, multiple views of the treatment i…
A set of concepts for modeling large real time systems is discussed informally. The concepts support the design of centralized as well as distributed systems. They are object oriented in that they correspond to entities of the 'real world', and they are 'change oriented' in that …
Although most attempts to speed-up Smalltalk have focused on providing more efficient interpreters, code optimization is probably necessary for further increases in speed. A type-system for Smalltalk is a prerequisite for building an optimizing compiler. Unfortunately, none of th…
Mach, a multiprocessor operating system kernel providing capability-based interprocess communication, and Matchmaker, a language for specifying and automating the generation of multi-lingual interprocess communication interfaces, are presented. Their usage together providing a he…
LOOM (Large Object-Oriented Memory) is a virtual memory implemented in software that supports the Smalltalk-80(™) programming language and environment on the Xerox Dorado computer. LOOM provides 8 billion bytes of secondary memory address space and is specifically designed to run…
Concurrent Prolog supports object-oriented programming with a clean semantics and additional programming constructs such as incomplete messages, unification, direct broadcasting, and concurrency synchronization [Shapiro 1983a]. While it provides excellent computational support, w…
Identity is that property of an object which distinguishes each object from all others. Identity has been investigated almost independently in general-purpose programming languages and database languages. Its importance is growing as these two environments evolve and merge.
