Automatic visualization of the dynamic behaviour of programs by animation of the language interpreter

A system for visualizing the dynamic behavior of programs written in the NeWS language is presented. Experience with the system's design and implementation is discussed. The functionality of the current prototype is described. By presenting multiple views of execution and supplying default animations for the various operators of the language and its dynamic concepts and mechanisms, the system can help the user develop a better feel for the execution model of NeWS.<
