点击翻译按钮获取中文摘要

This report presents a menu-selection method in program design process and an automatic drawing technique of the obtained design diagrams for improving software productivity and maintainance. Users search for appropriate procedures of statements and program modules by looking for the call sentences in the headline dictionary shown in a display for a procedure key given by a user. Users' native language can be introduced to tjhe call sentences for increase in their readability. Users select an appropriate call sentence to given specifications from the dictionary and customize some of the involved parameters to meet the given specifications. The body part of control call sentence is customized recursively in a top_down manner. Each call sentence can be automatically transformed to a structured diagram and sequentially added to that of the design document for intuitively inspecting the program design. The design document can be directly used to automatic generation of C program and maintainance.
