The HIBOL-2 environment: A basis for visual programming of business objects
Abstract This article introduces the HIBOL-2 environment, a basis for visual software development for business applications. It shows why visual programming is needed in areas with little inclination toward programming. Further, it shows the differences between languages designed for visual programming as opposed to environments for visualizing conventional language constructs. But it is also shown that, based on our experience with HIBOL-2, even in languages that are founded on graphical representation, additional support structures are needed to ease the programming task.
