Abstract
. The functional programming language Clean offers an extensive library, the object I/O library, to programmers to create interactive applications that use Graphical User Interfaces (GUI). Programs are constructed by composition of interactive objects. Interactive objects share state. To support modular programming it is also possible to provide objects with local state. Hierarchies of stateful objects are defined by means of algebraic specifications. Good use is made of the fact that Clean is a strongly typed language. In this paper we show how the evaluation of interactive objects is implemented in the object I/O library. The evaluation can be handled elegantly using lazy evaluation. 1 Introduction For many years the functional programming language Clean [7, 13, 14] enables programmers to create efficient, interactive applications that use Graphical User Interfaces (GUIs). This is done by means of an extensive library that has been developed in Clean. The first publicly av...
