Abstract

PROBLEM TO BE SOLVED: To shorten the man-hour of the management of revised edition and to improve accuracy by recording correction information for a source program at the time of correcting the source program and automatically generating a revised edition history by means of correction information and a source program list. SOLUTION: A correction information recording means 2 records executed editing work, a corrected part and a corrected content in a correction information recording file 3 when the source program is corrected. At the time of generating revised edition history, a revised edition history generation means 5 automatically generates revised edition history 6 based on the correction information recording file 3 and the changed source program list (the file outputted by an editor and the like after the editing operation of the source program is terminated, for example) 4. Namely, the revised edition history generation means 5 reads the correction information recording file 3 and obtains an editing code, the line number of the corrected part, the corrected content and date/time when correction is executed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic change history creating system, and more particularly to an automatic revision history creating system for a source program.

[0002]

2. Description of the Related Art A source program consisting of a program instruction sequence described according to a language specification such as a predetermined high-level language or assembly language is compiled or assembled into an object code (machine language). After the conversion, the predetermined library or the like is added and an address (real address) is assigned to produce an execution module (load module), and this execution module is executed on the computer system. By the way, the source program is often changed in order to correct and improve detected bugs (errors in the program), change design specifications, etc.
Rework may be performed after shipment or delivery of the software product, and the version of the original program may also be revised sequentially (improving or improving the functions of the existing software in this way is also called "version upgrade"). ).

Conventionally, when managing the revision history of a source program, generally, a method of manually comparing the source program before the change and the source program after the change and manually creating the revision history is adopted. It was being done.

[0004]

As described above, conventionally, the revision history of the original program is manually compared by comparing the original program before the change and the original program after the change with a printer output or visually on the screen. Since the changes were extracted and created, it takes a lot of man-hours to manage the revision of the source program, and it is difficult and inefficient to avoid human errors such as oversights and mistakes specific to manual work. There were various problems. In particular, with the recent increase in the size of software and the increase in the total number of steps of a source program, it has become extremely difficult and complicated to manually manage revision history management.

Therefore, the present invention has been made in view of the above problems, and provides a system in which the revision history of a source program is automatically created, the number of revision management steps is shortened, and the accuracy is improved. With the goal.

[0006]

In order to achieve the above object, the present invention provides a modification information recording means for recording modification information for a source program when the source program is modified, the modification information and the source program. (EN) An automatic change history creating system for a program, which comprises: a revision history creating means for automatically creating a revision history according to a list.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram schematically showing the configuration of an automatic program change history creating system according to an embodiment of the present invention.

Referring to FIG. 1, in a terminal 1, a source program is edited by a predetermined editor or the like. The modification information recording means 2 is used for editing work, modification points, and
And the correction contents are recorded in the correction information recording file 3.

One record of the correction information recording file 3 is
An edit code indicating an edit operation performed on the terminal 1, a line number of a correction location (for example, a line number added in ascending order from the beginning of the source program), a correction content, and a date and time when the correction is performed.

The editing operations performed are classified into, for example, moving, adding, correcting, replacing, etc., and a predetermined editing code is assigned to each editing operation.

In the case of deleting, modifying and replacing operations, the relevant line of the original program before the modification is recorded in the modification information recording file 3 as the modification content.

At the time of creating the revision history, the revision history creating means 5 stores the revision information recording file 3 and the modified source program list 4 (for example, a file output by an editor or the like after the editing operation of the source program). Based on this, the revision history 6 is automatically created.

That is, the revision history creating means 5 reads the modification information recording file 3 and obtains the edit code, the line number of the modification location, the modification content, and the date and time at which the modification was performed.

When the edited code is moved or added by referring to the edit code, the corresponding line of the source program list 4 after the change is read based on the line number of the corrected portion, It is a correction content.

The revision history 6 output from the revision history creating means 5 includes the source program name, the revision history creation date and time, the line number of the correction location, the editing operation performed, the correction content, and the date and time when the correction was performed. For example, they are sorted in the order of the line numbers of the source program and output through the screen on the terminal 1 or an output means such as a printer device (not shown).

At this time, the range of the correction content to be output, for example, the line number and / or the date and time can be selectively designated by the input means of the terminal 1. In this case, the revision history creating means 5 is executed. The specified line number range of the modification,
Alternatively, the revision history 6 is extracted and output only for the date and time.

[0018]

As described above, according to the present invention,
The revision history of the original program is automatically created, the revision history can be created accurately in a short time, and the man-hour required for revision management can be reduced and the accuracy can be improved.
