CONSTITUTION:Base paper is in a high hierarchy and a title, a timer, and a document are in a low hierarchy. When the visual programming of image output devices 1 and 2 is performed, the programming is carried out while the respective objects of the title, timer, document, and base paper are divided into models, representations, preferences, and widgets. The models are essential data and procedures of the object that the user share. The representations are the visual representation which are common to the corresponding model users and data required for them. the preferences are visual representations special for the respective users and data required for them.
