【摘要】 二级控制图可很清楚地反映程序的模块间及模块内的逻辑控制关系,它是静态分析非常有用的辅助工具.本文详细描述了从COBOL程序到二级控制图的转换工具TTPCD(Tool for Transformation from Program in to Two LevelControl Diagram)实现原理、技术和功能,并指出该工具进一步发展的前景。更多还原

【Abstract】 The two level control diagram can represent clearly the logical control re- lations both outside and inside program modules.In this paper,we give a de- tailed description of the implementation principles and techniques and func- tions of the transformation tool-TTPCD,and put forward the prospect of the tool.更多还原
