Abstract

There are a number of reasons why a user might want to move data structures between Smalltalk images. Unfortunately, the facilities for doing this in the standard Smalltalk image are inadequate: they do not handle circular structures properly, for example. We have implemented a collection of Smalltalk methods that handles circular structures; in addition, these methods have a number of other advantages over those provided in the standard image. This paper is largely a discussion of the issues that arose during their design, implementation, and use.
