法に関する。Description: TECHNICAL FIELD The present invention relates to a PAD figure arranging method, and in particular, when outputting a PAD figure on an output device such as a printer or a display, it is optimal for making the PAD figure easy to see. The method of arranging and arranging.
計算機プログラムの構造を図形で表現する手法の一つに
ＰＡＤ（問題解析図；Problem Analysis Diagram）があ
る。ＰＡＤの利点は従来のフローチャート等に比べ、プ
ログラム構造が理解しやすいことである。PAD (Problem Analysis Diagram) is one of the methods of expressing the structure of a computer program by a figure. The advantage of PAD is that the program structure is easier to understand than the conventional flow chart.

置となっている。This type of PAD can be changed from the handwritten PAD described by the designer at the time of designing the processing procedure to the P
The AD system has moved to machine-written PAD that writes in machine and outputs to a printer or display. As shown in the output example in FIG. 2, the conventional machine-written PAD has a connection source PAD figure and a connection destination PAD. The height of the beginning of the figure is the same position.
なお、このような機械書きＰＡＤ図形については、日立
評論、６６，３，ＰＰ１５〜１８（昭和５９〜３）に記
載されている。Note that such a machine-written PAD figure is described in Hitachi Review, 66, 3, PP 15-18 (Showa 59-3).

しようとするとき、ソフトウエア設計者の思考が中断さ
れるという問題があった。The conventional machine-written PAD has a connection source PAD figure and a connection destination P.
Since the tops of AD figures are at the same position, there are many areas where PAD figures are not written, and human handwritten PAD
There is a problem that the number of pages becomes larger than that of, and the thinking of the software designer is interrupted when trying to understand the program structure.
本発明の目的は、ＰＡＤ図形が書かれていない領域を少
なくして、出来るかぎり手書きＰＡＤに近ずけ、利用者
の見易いＰＡＤ図形配置方法を提供することにある。It is an object of the present invention to provide a PAD figure arranging method in which the area where the PAD figure is not written is reduced so that the PAD figure is as close as possible to the handwritten PAD and is easy for the user to see.
上記目的は、接続元ＰＡＤ図形の配置位置より上方にも
接続先ＰＡＤ図形を配置し、関連するＰＡＤ図形を出来
るだけ近くに集めることにより、達成される。The above-mentioned object is achieved by arranging the connection destination PAD graphic above the layout position of the connection source PAD graphic and collecting related PAD graphics as close as possible.
接続元ＰＡＤ図形に対する接続先ＰＡＤ図形の配置を決

つ、出力されるＰＡＤ図形を見易いものとすることがで
きる。When deciding the arrangement of the connection destination PAD graphic with respect to the connection source PAD graphic, it is checked whether or not there is an empty area for arranging the connection destination PAD graphic above the arrangement position of the connection source PAD graphic. The connection destination PAD graphic is arranged in the empty area above the arrangement position of the original PAD graphic. As a result, the area where the PAD graphic is not written can be reduced, and the output PAD graphic can be easily viewed.
