する。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to printing a changed portion of an old and new source program when changing a source program, and more particularly to a program comparison and determination method suitable for determining the same portion and the changed portion. .

る。The conventional source program change check is disclosed in JP-A-57-123.
There is a check at the time of editing a source program as shown in Japanese Patent No. 448, but this method cannot be used in the final check after a plurality of changes have been made. As a method of checking whether or not a new source program that has been changed a plurality of times has been changed correctly, it is effective to check the result of comparing old and new source programs with the changed contents.
しかしながら、第１図で示されるように新旧ソースプロ
グラムの比較判定結果において、実際の変更はａの部分
の削除であるが、比較判定の方法によっては比較結果と
変更箇所が一致しないという問題があった。However, as shown in FIG. 1, in the comparison judgment result of the old and new source programs, the actual change is the deletion of the portion a, but there is a problem that the comparison result and the changed portion do not match depending on the comparison judgment method. It was
本発明の目的は、上記問題点を解決するためになされた
もので、内容の全く同じ行が複数ある一般的なソースプ
ログラムに対して任意の変更がなされたとき、その変更
個所を変更前後の新旧ソースプログラムの比較から自動
的に識別するプログラム比較判定方法を提供することに
ある。The object of the present invention is to solve the above problems, and when an arbitrary change is made to a general source program having a plurality of lines having exactly the same contents, the change points before and after the change are changed. It is to provide a program comparison determination method for automatically identifying from comparison of old and new source programs.
第１図において、新旧ソースプログラムの比較判定で、
比較結果と変更個所が一致しないのは、DO文やEND文の
様な内容の全く同じ行が複数ありその対応関係を考慮し
てないことに起因する。したがって本発明は連続一致部
分の多い順に同一と判定していくことにより、上記問題
を解決している。即ち、第２図に示されるように比較判
定は最初に９行が連続一致するｂの部分を同一と判定
し、次に１行が一致するｃの部分を同一と判定する。そ
して残った不一致部分ｄを新旧ソースプログラムの対応
関係から削除されたと判定する。In Fig. 1, in the comparison judgment of the old and new source programs,
The reason that the comparison result and the changed part do not match is that there are multiple lines with exactly the same contents such as the DO statement and END statement, and the corresponding relationship is not considered. Therefore, the present invention solves the above-mentioned problem by determining that the areas are the same in descending order of the number of consecutive coincident portions. That is, as shown in FIG. 2, in the comparison determination, first, the portion of b in which 9 rows continuously match is determined to be the same, and then the portion of c in which 1 row matches is determined to be the same. Then, it is determined that the remaining unmatched portion d is deleted from the correspondence between the old and new source programs.
従って、本発明は、修正前の旧ソースプログラムと修正

ることを特徴とする。Therefore, according to the present invention, in the method of comparing and judging the old source program before correction and the new source program after correction and printing the judgment result, the comparison judgment criterion based on the coincidence of a plurality of consecutive lines is provided. It is characterized in that the same part is sequentially extracted from the part having the largest number of consecutively matching lines while the number of lines is sequentially reduced, and the remaining part is determined as a corrected line for addition, deletion, or replacement.

７へ出力し印刷する。Next, the comparison processing procedure will be described with reference to the flowchart of FIG. First, the old and new source programs 1 and 2 are loaded into the old and new source program storage tables 5 and 6, and a numerical value 16 is set as the number N of consecutive coincident lines which is a comparison judgment criterion (step 8). Next, the old and new source program storage tables are compared and scanned, and consecutive matching portions of N lines or more are extracted (step 9). If there is a continuous matching part for N lines or more, a flag indicating the matching is added to the old and new source program storage table 5,
The comparison result area 12 of 6 is set (step 10). When the comparison target remains, the process returns to step 9, and when the comparison target disappears, the value of N is decremented by 1 (step 11). N
Is 0 or less, the process returns to step 9, and if N is 0 or less, the comparison result area 12 is referred to and the comparison result is output to the printer device 7 for printing.
