Abstract

PURPOSE:To accurately manage plural programs having proper functions respectively by one program file by providing a segmentation means, a function addition and correction means, and a registration means. CONSTITUTION:First, a correction program 12 for condition B is segmented from the program file 11 by the segmentation means 2. Next, a correction program 13 in which a difference 17 related to the condition B is added on the correction program 12 is generated by the function addition and correction means 3. Furthermore, the correction program 13 is registered on the program file 11 by the registration means 4, and the program file 14 is generated. At this time, it follows that a segmenting condition 61 for condition B is automatically inserted to the neighborhood of the difference 17 and a difference 16 with segmenting condition exists in the program file 14. Consequently, it results that the program file 14 includes a common part and the difference with realizes a function proper to the program executed at the time of satisfying the conditions A and B.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a program (computer program) difference management method, and in particular, to a method for managing differences between programs (computer programs), and in particular, functions common to all programs and programs executed when specific conditions are met. The present invention relates to a program difference management method for managing a plurality of programs having functions unique to each other with an awareness of differences (parts that realize functions unique to each program (including functions common to a plurality of programs but not all)).

[Conventional technology]

Conventionally, in one program difference management method of this type, program 21 for condition A, program 22 for condition B in FIG. ...Program 2 for 2 conditions N (positive integer)
N (A program that is executed when conditions A, B, ..., N are satisfied. These programs have a part that realizes a common function (common part) and differences 31°32, ...3N. ) is managed, each program (program for condition A 21, program for condition B 22...
・Each of 9 program 2N for condition N) is condition A,
B, . . . , N were managed separately.

Further, in another method of this kind of program difference management method, program 21 for condition A in FIG. Program for condition B 22. ...Respective differences in program 2N for 1 condition N 31.32. ..., conditions for manually extracting before and after 3N (conditions that instruct to extract the program containing the differences 31, 32, ..., 3N corresponding to the case where conditions A, B, ..., N are satisfied) is inserted (added), and the difference 41.42. with the extraction condition is inserted. ..., 4
A program file 20 including multiple functions having N allows multiple programs (program 21 for condition A, condition B
Program for 22. ...Program 2N for 1 condition N)
was being managed.

[Problem to be solved by the invention]

In the former of the conventional program difference management methods described above, each program is managed separately for each condition, which increases the total program capacity and requires additions or modifications to functions common to all programs. The disadvantage is that the program must be processed several times when the problem occurs.

Furthermore, in the latter method of the conventional program difference management methods described above, the cutting conditions must be manually inserted before and after the difference, so there is a drawback that errors are likely to occur when the conditions become complicated.

In view of the above-mentioned points, an object of the present invention is to provide a program difference management method that allows a single program file to accurately manage a plurality of programs each having a unique function.

[Means to solve the problem]

The program difference management method of the present invention includes an extraction means that extracts a modified program for a specific program based on extraction conditions regarding a specific program in a program file, and a function for the modified program extracted by this extraction means. a function addition/modification means for adding or modifying a function; and a registration means for adding an extraction condition to a difference in a modified program in which functions have been added or modified by the function addition/modification means and registering the modified program in the program file. has.

[Effect]

In the program difference management method of the present invention, the extraction means extracts a modification program for a specific program based on the extraction conditions regarding the specific program in the program file, and the function addition modification means makes the modifications extracted by the extraction means. Functions are added or modified to the program, and the registration means adds extraction conditions to the differences in the modified program in which functions have been added or modified by the function addition/modification means, and registers the modified program in the program file.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the program difference management method of the present invention. The program difference management method of this embodiment includes an extraction means 2 and a function addition/modification means 3.
, registration means 4, and program files 11 and 14.
and modification programs 12 and 13.

The program file 11 is configured to include a difference 15 with an extraction condition.

The correction program 13 is configured to include a difference) 17 to which a difference extraction condition is not added.

The program file 14 includes a difference 15 with an extraction condition and a difference 16 with an extraction condition (the difference 17 has an extraction condition 6).
(difference with 1 added).

The difference with a cutout condition 15 has a cutout condition 51 that instructs to cut out the difference related to the cutout conditional difference 15 when the condition A is satisfied, and the cutout conditional difference 16 has a cutout condition 51 that instructs to cut out the difference related to the cutout conditional difference 15 when the condition A is satisfied. Conditional difference 1
Extraction condition 61 instructing to extract the difference related to 6.
(rlF condition = AJ and rENDJ in Figure 1 and IF condition = BJ and rEN
DJ is a simplified representation of each cutting condition 51 and 61).

Next, the operation of the program difference management system of this embodiment configured as described above will be explained. In addition, here, when adding a difference 16 with an extraction condition related to condition B to a program file 11 consisting of a common part and a difference 15 with an extraction condition related to condition A (adding a unique function when condition B is satisfied) This section explains the operation when

First, the cutting unit 2 cuts out the correction program 12 for condition B (the correction program for the program to be executed when condition B is satisfied) from the program file 11. In this case, since there is no difference related to condition B, a program consisting only of common parts is obtained as the modified program 12.

Next, the function addition/modification means 3 executes the modification program 12.
Modified program 1 in which difference 17 related to condition B was added to
3 is generated. Note that no cutout conditions have been inserted (added) before or after the difference 17 at this time.

Further, the registration means 4 registers the modification program 13 in the program file 11 and registers the modification program 13 in the program file 11.
4 is generated (the part added or modified in the modified program 13 (in this case, the difference 17) is reflected and the additions or modifications are made in the program file 11)
, at this time, cutout condition 6 for condition B is placed before and after difference 17.
1 is automatically inserted, and the cut-out conditional difference 16 exists in the program file 14. Therefore, the program file 14 includes the common part and the differences (extract conditional differences 15 and This includes a difference 16) with a cutout condition to which the cutout condition 61 for condition B is added.

Note that although the above description has been about adding functions, the same procedure can be used to modify functions. That is, for example, when the difference 16 with the extraction condition in the program file 14 is modified, the extraction means 2 extracts the modification program for condition B, and the function addition modification means 3 extracts the difference with the extraction condition in the modification program. A modified program in which the differences related to 16 are modified is generated, and the registration means 4 registers the modified program in the original program file 14 to generate a new program file.

In addition, to add or modify functions common to conditions A and B, the extraction means 2 extracts all of the program files as a modified program, and the function addition/modification means 3 adds or modifies a predetermined function to the modified program. The modified program in which functions have been added or modified is registered in the original program file by the registration means 4 and executed. Therefore, additions and corrections in this case can be completed in just one process.

(Effects of the Invention) As explained above, the present invention enables accurate management of a plurality of programs each having a unique function in one program file by providing an extraction means, a function addition/modification means, and a registration means. It has the effect of being able to.

Additionally, by managing multiple programs with one program file as described above, the total program capacity can be reduced, and common parts (common functions) can be added or modified in one process. It has the effect of being able to
