This paper is a user\u27s manual for BEMAS, a Belief Maintenance System. BEMAS is a menu driven system which provides an easy to use interface between a user and a knowledge base. Given a set of data, and a set of rules, BEMAS will help the user to identify an object by analyzing the properties of that object. Data can be added and deleted at any time, either directly or by deleting beliefs on which the data is dependent. BEMAS maintains the relations and dependencies between data using a dynamic dependency net. BEMAS also has the capability to make inferences using incomplete information while still maintaining knowledge base integrity
