Zusammenfassung:	Abstract: "As part of the fifth generation project at ICOT, we have been developing an object-oriented logic programming and operating system, SIMPOS, for the personal sequential inference machines: PSI and PSI-II. Currently, about three hundred PSI machines and some other machines have been connected in a local area network and in global area network, and two different protocols: PSI-NET and TCP-IP are supported over the network. For a distributed system to be built network-transparent most simply and compactly, it should be network-transparent at the base, that is at the method call level for an object-oriented system This paper describes the principles and implementation of the Remote Object Access Mechanism (ROAM), which is a general mechanism embedded in SIMPOS to invoke methods to objects on remote PSI machines as well as to objects on the local PSI machine. ROAM has been implemented as a set of classes. Network-transparent objects can be defined easily only by inheriting a ROAM interface class and customizing some of the inherited methods. ROAM is currently in operation for both of the above two protocols. Using ROAM, a variety of application software has been developed for practical use, one of which, a global file system, is shown as an example.
