Abstract

PURPOSE:To compare data to the last one by skipping the data, and next, setting arbitrary locations to be compared, and further, continuing the comparison of the data. CONSTITUTION:On the display screen of a display 100, the data in data files A and B and the comparison result of both data, etc., are displayed, and an conversational data comparison program 300' in a processor 300 performs the comparison of the data and the processing of the skip of the data, etc., according to an inputted command. When the start of comparison is indicated, the data is taken out from each data file and is compared one by one, and when noncoincidence is generated in both data, the comparison is interrupted at that time, and the fact of the noncoincidence of both data is informed to a user by displaying. The user skips the location from the one where noncoincidence is generated to the one to be compared by a large distance by using a prepared command, and continues the comparison again from the location. In such a way, the data can be compared to the last one.

Description

[Detailed Description of the Invention] [Summary] Regarding the improvement of an interactive data comparison method, it is possible to efficiently compare data, skip data, set an arbitrary location to compare next, and continue comparing data. The purpose is to provide an interactive data comparison method that allows data to be compared until the end.
.

A comparison command to compare the areas of data file A and data file B, and if there is a loss, continue comparing the next data until there is a mismatch, and a specific character string for data file A. The configuration requirements include a first discovery command for skipping until a specific character string appears in data file B, and a second discovery command for skipping data file B until a specific character string appears.

[Industrial application field]

The present invention relates to an improved interactive data comparison method.

[Conventional technology]

When comparing two data files such as source programs, conventional methods include: (1) outputting the contents of the two files to a line printer and visually comparing the printed characters;

■ Display the contents of the two files on a screen using two terminal devices (or a screen divided into two using the split function on one terminal device) and visually compare them.

■ The conveyor program compares two files and reports the results. There was a 7th method.

[Problem to be solved by the invention]

With method ■ or ■, humans may miss something because they are limited to visual inspection.

In method (2), once a discrepancy occurs, whether the cause of the discrepancy is (a) the discrepancy due to data being deleted, or (b) the discrepancy due to data being added, or Since the degree of deviation cannot be determined by the program, there is a drawback that everything after the point where the mismatch occurs is considered to be a mismatch.

The present invention was created in view of these points, and it is possible to efficiently compare data, and also allows data to be skipped, a desired location to be compared to be set next, and further data comparison to be continued. The purpose of the present invention is to provide an interactive data comparison method that allows data to be compared until the end.

Data file A is displayed on the display screen of display 100.
, the data of data file B, the comparison results between the two, etc. are displayed. The user can input various commands using the keyboard 200, and also
You can also enter seed commands using the keys. Interactive data comparison program 30 within processing device 300
0' performs processing such as data comparison and data skipping according to input commands.

FIG. 3 is a diagram illustrating an overview of data file comparison according to the present invention. In the figure, ■ indicates a match between the two data, ■ indicates a mismatch between the data, ■ skips to the point where the comparison starts due to the user's command, ■ indicates a match between the data, and ■ indicates the end of the data (comparison). End), sX,!
:XX indicates data, respectively.

When the start of comparison is instructed, data is extracted one by one from each data file and compared. When the two data match, the next data is compared sequentially (see (■)). When a mismatch occurs, the comparison is stopped at that point, and both data are displayed to confirm the match. The user is notified that there is no discrepancy (see ■).The user uses the provided command to skip a large distance from the point of mismatch to the next point to be compared (see ■).The user is instructed to start the comparison again. From there, continue the comparison in the same way (see ■). Repeat the above and compare until the end, and stop when some data is missing (■
reference).

FIG. 4 is a diagram showing an example of a display screen. As shown in the figure, the display screen has a data comparison area, an area for displaying the contents of two data files, an area for inputting commands, and an execution result display area for displaying the execution results. It will be done.

In the data comparison area, the contents of the beginning of each data file are displayed one line at a time, and in each data area seven lines of the next data are displayed. At this point, if there is an instruction to start comparison (C command; see Figure 5), INPUT-^ and INPU
Data is transferred line by line from the T-H data area to the comparison area and compared. If the data match, the next data is also sequentially compared. If the data do not match, stop the comparison at that point, display both data, and display the result (“UNMATCH”)
Display of).

The user skips the data to the next location to be compared (G, F commands: see Figure 5). When the start of the comparison location is aligned, the user is instructed to start the comparison again, and the same process as above is performed. Let's continue the comparison.

When there is no data in either the data area of lNPt1↑-A or INPUT-B, "EOF" is displayed and the comparison ends.
