程序框图的结构化设计

Structured Design of The FLOWCHART

程序框图作为辅助程序员。设计程序的工具，有许多明显的优点，由于它能够形象直观地反映问题的逻辑结构，在设计程序时，首先作出问题的程序框图，再写程序，可以克服直接用程序语言表述问题，需要高度抽象过程的困难。但是传统编制框图的方法，存在难于修改和不大适应结构设计风格的缺点。 本文提出了对于传统框图的改进，可以使设计框图的过程适应于程序的结构化设计。井设计了一套程序框图的编辑方法，可以明显提高设计框图的质量。

The FLOWCHART has many advantages as a tool assisting, programers to design programs.Because it shows the logical structure of the problem to be solved and overcomes the difficulties for a programmer to describe the, problem directly with program languaes which need high level abstract processes. There are,however,some disadvantages within tranditional FLOW- CHART methods.It is not modified easily.It is not suitable to the structured program design scheme either. This paper proposes some improvements for the tranditional FLOW- CHART design methodes. It makes the FLOWCHART design process stuitable to any structured program design. Also, a set of editing methods of the FLOWCHART, which raises the quality of the FLOWCHART designed, has been provided in the paper.
