摘　　要：以树型图为基础,吸收了N-S图和PAD图等图形工具的优点,创建了程序设计的一种新的辅助工具——PAT图(program m ing aiding tree).其基本图符由顺序结构、选择结构、循环结构、开始和结束、sw itch 结构、块结构、图形续接和模块8 种组成,符合程序设计的结构化和模块化的要求.与ISO流程图、N-S图和PAD图相比。A new graphic tool to program design—PAT(programming aiding tree) has been established.It is made on the basis of tree type graph and inspired by the decision tree of an algorithm and by N S graph and PAD.The PAT is a system consists of eight basic icons: sequence,selecting,circulating,start & end,switch,block,connection and modular.It meets the requirement of constructivity and modularization of program design.It has clear advantages in expressing the logic structure and the hierarchy structure of a program comparing with the current three programming graphic tools:N S graph,PAD and ISO diagram.
