This paper shows how a multimedia multi-framed simulation generator was developed. A technique of recording a sequence of steps and playing them back as an animation overcomes the major problems with the synchronous mapping of components which execute asynchronously and non-sequentially It also preserves the integrity of instructional design. A simulation of any executing program code segment can be produced in a few hours using this generator. Four frames can simultaneously display different representations of the segment as text or graphical images. Users can step through the simulation or have it run at variable speed, and can change specified code statements to increase learning potential. The Animated Simulation Generator could be used for any ffame-based animation requiring complex sets of interrelated text andlor graphical components. Keywords Software visualisation, animation, simulation.
