Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a source program change history creation utility, and more particularly to a source program change history creation utility for outputting a source program change history in combination with a source program modification utility for modifying a source program. ..

[0002]

2. Description of the Related Art Conventionally, this type of source program change history creation utility has not been used, but the source program modification utility has been used independently to add, modify, delete records (rows) of the source program, and output the results. For this reason, it is configured as shown in FIG.

The source program modification utility shown in FIG. 3 is an external input device 2 for inputting a source program, a console 1 for performing work operations, a central processing unit 7 for registering, changing and deleting a saw program under software,

[0005]

The above-mentioned conventional source program modification utility writes only the source program in the final state. Therefore, in order to keep a history of changes, the deletion information and the modification information are commented and written. However, there is a problem in that there is an unnecessary number of lines in the source program. In addition, when changing or modifying the same line, it is difficult to add a comment, and it is difficult to grasp the contents before modification because the comment is not entered. Further, the source program is often modified irregularly, and it is a great burden for the SE and the programmer to fill in the modified content without fail.

[0006]

A source program change history creation utility of the present invention is a source program change history creation utility that outputs a change history of a source program in combination with the source program modification utility. When storing a source program having the same name as that already stored in the storage unit, the registration means for discarding the history information of the source program that is held and storing / registering the input source program, and the registration means Before revising the stored / registered source program, save this source program in a temporary storage device, compare the revised source program after the revision with the saved source program, and enter the contents before and after the revision. Editing means to save as The history information of the designated source program is displayed in response to the restoration request specifying the program name, and the restoration means restores the source program according to the history contents from the latest history information to the designated history. ..

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, and FIG. 2 is a flow chart of the operation of the embodiment of FIG. Figure 1
In this embodiment, a console 1 for operating and displaying, an external input device 2 for inputting a source program, a central processing unit 3 for registering, changing, deleting the source program and creating history information under software, before correction. The central processing unit 3 comprises a temporary storage device 4 for saving the source program, an auxiliary storage device 5 for storing the source program and history information, and an output device 6 such as a printer. The central processing unit 3 has a registration unit 31, an editing unit 32, and an updating unit 33. , And a search means 34, and the auxiliary storage device 5 has a source program storage unit 51 and a history storage unit 52.

Next, the operation of FIG. 1 will be described with reference to FIG. The operations are roughly classified into registration (A), editing (B), and search (C). Registration (A) is external input device 2
To register the source program in the source program storage unit 51 of the auxiliary storage device 5. When a source program input request is made, the registration means 31 first checks from the program name whether it is a new program (step 10).
1, 102), if the same program name has already been registered, the operator is requested to enter a judgment as to whether or not to delete the history information of the program and start again (10
3) If the deletion is to be made again, the history information is deleted and the registration processing is performed (steps 104 and 105). If it is new in step 102, the registration process of step 105 is immediately performed. If it is not deleted in step 103, the registration process is not performed again.

Edit (B) is an operation of updating the source program, creating history information, and storing it in the history storage section. The editing means 31 causes the updating means 33 to modify and change the program, edits it, and stores it in the source program storage section 51 (step 201). At this time, the updating unit 33 first calls the target source program from the source program storage unit 51 and saves it in the temporary storage device 4. Then, when the storing of the edited source program is completed, the editing means 31 causes the operator to input the history title. For example, "change calculation formula", "add file item", etc. are input (step 202). When the title is input, the contents stored in the source program storage unit 51 are compared with the contents saved in the temporary storage device 4, and the contents of the different portion are recorded together with the history title.
The history information is additionally stored in the history storage unit 52 (step 203).

The search (C) includes a restore operation (D), a display operation (E), and a delete operation (F). When the retrieval means 34 receives a request for restoration, display, and deletion related to the history details from the operator console 1 together with the designation of the source program name (step 301), it displays the history titles with history numbers related to the source program in the order of creation date. ((Step 302). Then, in the restoration (D), the operator inputs the displayed date and history number (Step 311). The retrieval means 34 calls the target source program from the source program storage unit 51, and the history information is displayed. The source program is returned and the history information is deleted according to the latest one or the history specified in order (step 312) When the deletion is completed, the target source program and the history information are output by the output device 6 (step 31).
3).

Next, in the display (E), when the operator designates the history number of the history title displayed in step 302 (step 321), it is output from the output device 6 or the history content is displayed on the console 1 ( Steps 322, 32
3). Next, in delete (F), the operator performs step 30.
When the history number of the history title displayed in 2 is designated (step 331), the operator is prompted to confirm (step 33).
2) The history contents from the beginning to the designated history number are deleted by confirmation input (step 333). If redisplay is requested after steps 323 and 333, the process returns to step 302 (step 341).

[0013]

As described above, the present invention is used in combination with a source program modification utility to store information about changes before and after modification as history information, and based on this information, a history number is designated and source information is stored. Since the program can be restored and the unnecessary history contents can be deleted, it is not necessary to manually create a correction document for the correction, and the restoration can be surely performed.
