Interactive simulation on a microcomputer

Abstract

The Apple II microcomputer provides powerful facili ties for the writing and execution of both discrete and continuous simulations. Interactive BASIC allows rapid development of new models, while color graphics provides results that are easy to analyze. Came paddles can allow the user to change parameters and control the simulation as it runs. Two new simula tion executives allow both the modeler and the user ready access to the facilities of the computer and the simulation, while preventing the user from making unreasonable or impossible changes. Despite its limited language facilities and relatively low speed, the microcomputer has obvious advantages in user inter action, model development, optimization, and analysis and presentation of results. Many of the microcom puter's limitations, furthermore, will soon disappear as more powerful languages and faster processors become available.
