A computer software system is provided, namely, An Object Process Graph Application Controller-Viewer (OPGACV) system. The OPGACV controls a running Object Process Graph (OPG) application by inducing a Dynamic Graph Interpreter (DGI) to transition applications from one state to another, and using application designer/user defined properties, it renders application state, structure, and data on display mediums and validates data inputs to applications. The OPGACV also controls the import and export of OPG applications.
