A universal language system for visual programming
Masaaki Hirakawa, M. Yoshimi, T. Ichikawa · 2002
A universal language system for visual programming is presented. Any specific visual programming system can easily be constructed using the system. The system is based on previous studies of VPS/VPSM, and is extended by providing a unified, object-oriented model of visual elements management and support tools which enable the system designer to construct visual programming systems more easily.>
