This paper introduces a hierarchical program visual model based on object, scope and type. It depicts a program's information through a recursive-nested structure. Particularly, it emphasizes on the inherent relationships among objects, scopes and types and connects objects and types within scopes. This paper explains all parts and their relationships in details and also addresses briefly about how to realize the model.展开更多
