CONSIM: a study of control issues in conversational simulation
Department of Computing Science, Texas A&M University, College Station, Texas, USA
CONSIM is a prototype conversational simulation language which provides simulation types of control and allows mid-execution editing of both programs and data. In its development CONSIM served as a vehicle for exploring the control issues inherent in the design, implementation, and use of such a programming system.
SIMULA 67 was used in the development of the prototype system both as a model for CONSIM's control features and as its implementation language. SIMULA was selected primarily because of its high level control facilities, including both coroutine and simulation sequencing. The dual use of SIMULA in this project allowed an implementation strategy called interpretive control self-modelling to be used.
This paper provides an overview of the CONSIM development by discussing the motivation of the research, highlighting CONSIM's interesting and unique features and illustrating its utility with excerpts from a model-building scenario. The prototype implementation is described and, finally, the results and promising areas for future research are summarised.
