Abstract

PURPOSE:To exactly find out an erroneously corrected line with the possibility of existence in a source program under alteration for function addition or the like in a short time. CONSTITUTION:When checking whether the source program under alteration at present is erroneously corrected or not, a programmer inputs an erroneously corrected line retrieving instruction from an input device 2. In response to this instruction, an input means 11 inputs the source program under alteration and a source program before alteration from a source file and stores them in a memory 12. Concerning the altered line in the source program under alteration, an identifier showing its kind is set by the programmer. Concerning the respective lines, to which the identifier is not set, in the source program under alteration, a comparing means 13 compares contents with the correspondent lines in the source program before alteration decided based on the kind of alteration shown by the identifier and outputs information showing the comparatively non-coincident lines.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention makes it possible to easily correct a line that has been erroneously corrected in a source program currently being modified stored in a source file on an external storage device such as a magnetic disk drive. The present invention also relates to an erroneously corrected row search device that can be searched for in a short time.

[0002]

2. Description of the Related Art When modifying the latest version of a source program and adding functions, the latest version of a source program stored on a magnetic tape or the like is copied to a source file on a magnetic disk device. It has been conventionally performed to remodel a source program by using it.

By the way, the source program stored in the source file on the magnetic disk device can be relatively freely referenced and updated by a plurality of users. The source program currently being remodeled may be erroneously corrected due to erroneous operation or the like.

Therefore, at an appropriate time during the remodeling of the source program or at the completion of the remodeling of the source program, it is checked whether or not there is a line in the remodeling source program that has been erroneously corrected. If the row exists,
You will need to restore the line to its original content.

For this reason, conventionally, it has been checked whether or not a source program being remodeled has a line that has been erroneously corrected as follows.

That is, an output list of a source program being remodeled and an output list of a source program before remodeling that are the basis of the source program are output.
Match rows line by line to find unmatched lines. Unmatched rows are
Since it is a line that has been erroneously corrected or a line that has been officially modified, if you find a non-matching line, determine whether that line has been erroneously modified or a line that has been officially modified. judge. By performing such operations until the end of the source program, an erroneously corrected line existing in the source program being remodeled is found.

[0007]

As described above, conventionally, a list of a source program under remodeling and a list of source programs before remodeling are manually compared with each other one line at a time to find a mismatched line. There is a problem that a lot of time is wasted because the erroneously corrected line is checked by determining whether the mismatched line is a line that has been erroneously corrected or a line that has been properly remodeled. At the same time, there was a problem of lack of accuracy.

It is an object of the present invention to provide an erroneous correction line retrieval device which can accurately and accurately find an erroneous correction line of a source program being remodeled.

[0009]

In order to achieve the above object, the present invention is a source program before modification and a source program modified based on the source program before modification. Input means for inputting from the source file a source program under remodeling in which an identifier indicating the type of remodeling is set in a line, and for each line in which the identifier in the source program under remodeling input by the input means is not set, The content is compared with the corresponding line in the pre-remodeling source program input by the input means, which is determined based on the identifier set in the reconstructing source program, and the information indicating the non-comparative line is output. And means for comparison.

Further, in order to achieve the above object, the present invention provides:
In the source program before modification and the source program modified based on the source program before modification, the type of modification is replaced with the contents of the line in the modified line.
Input means for inputting, from a source file, a remodeling source program in which an identifier indicating addition or deletion of a line is set; and a head of the pre-remodeling or remodeling source program input by the input means. When the line is set as the attention start line and the identifier is not set for the line of interest in the remodeling source program, the contents of the line of interest in the source program before and after modification are compared. If the comparison matches, the line of interest is changed to the next line in both the source program before and during the remodeling, and if the comparison does not match, information indicating the line of current interest is output, and then the target line is focused. If the line before the remodeling and the source program under remodeling are changed to the next line, and the line of interest in the source program under remodeling is set with an identifier indicating the replacement of the line contents, Changes the line of interest both to the next line before the remodeling and the source program being remodeled, and if an identifier indicating addition of a line is set to the line of interest in the source program being remodeled, The line of interest is changed to the next line only for the source program being remodeled, and if an identifier indicating deletion of a line is set for the line of current interest in the source program being remodeled, the line of interest is changed to the following line. Both the source program before and during the remodeling have comparison means for changing to the next line.

Further, in order to achieve the object of enabling the processing speed to be increased in the case where the program being modified is modified by deleting a plurality of consecutive lines, The identifier indicating the deletion of a line includes the number of deleted lines indicating how many lines have been deleted consecutively from the line to which the identifier is set, and the comparison means is currently focused on in the reconstructing source program. If an identifier indicating the deletion of the line including the number of deleted lines is set in the existing line, the line of interest is changed by the number of deleted lines in the pre-modification source program, and Change to line.

Further, according to the present invention, when the erroneous correction changes the number of lines such as deleting a line or adding a line,
To prevent inconsistencies in the comparison results of all lines after the line where the above erroneous correction was made,
The remodeling source program is divided into sections, and if the identifier of the current line of interest in the remodeling source program is not set, the comparing unit outputs the current program in the pre-remodeling and remodeling source program. If the content of the line being compared is a comparison match, the line of interest is changed to the next line in both the source program before and during the remodeling,
If the comparison does not match, the information indicating the currently focused line is output, and then the focused line is changed to the start line of the next section in both the source program before and during the remodeling.

[0013]

The input means is a source program before remodeling, and a source program remodeling based on the source program before remodeling, wherein a remodeling line is set with an identifier indicating the type of remodeling. Input the middle source program from the source file.

The comparing means, for each line in the source program being remodeled for which no identifier is set, determines the corresponding line and content in the source program before remodeling determined based on the identifier set in the source program being remodeled. Are compared and the information indicating the row in which the comparison does not match is output.

The identifier indicates, for example, whether the type of remodeling is replacement of line contents, addition of lines, or deletion of lines.

When the identifier is such, the comparing means sets the first line of the source program before and under modification as the starting line of interest, and sets the identifier on the line of interest in the source program under modification. If not, before remodeling,
If the contents of the line of interest in the source program under remodeling are compared and the comparison is a match, the line of interest is changed to the next line in both the source program under remodeling and the source program being remodeled. After outputting the information indicating the line of interest (the line where the contents do not match), change the line of interest to the next line for both the source program before modification and the source program under modification.

If an identifier indicating replacement of the line content is set in the line of interest in the source program being remodeled, the line of interest is changed to the next line in both the source program before remodeling and the source program being remodeled. I do.

Further, when an identifier indicating addition of a line is set to the line of interest in the source program being remodeled, the line of interest is changed to the next line only for the source program being remodeled.

If an identifier indicating deletion of a line is set in the line of interest in the source program being remodeled, the line of interest is changed to the next line both in the source program before remodeling and in the source program being remodeled. .

Further, the identifier indicating deletion may include the number of deleted lines indicating how many consecutive lines have been deleted from the line in which the identifier is set.

In this case, if the identifier indicating the deletion of the line including the number of deleted lines is set in the line of interest in the source program under remodeling, the comparing means changes the line of interest with respect to the source program before remodeling. Is changed by the number of deleted lines, and the source program being modified is changed to the next line.

Further, the source program before and during remodeling is divided into sections, and the comparing means determines whether or not an identifier is set in a current line of interest in the source program during remodeling, if the source program before and during remodeling is not modified. Compare the contents of the currently focused line in the comparison, and if the comparison is consistent, change the focused line to the next line in both the source program before and during the remodeling, and if the comparison does not match, focus on the current line After the information indicating the line is output, the line of interest is changed to the start line of the next section in both the source program before and during the modification.

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention.
, A display device 3 such as a CRT, a printer 4, and a plurality of source files 5-1 to 5 storing source programs.
-N.

The erroneously corrected row search device 1 includes an input unit 11,
It comprises a memory 12, a comparing means 13, and an output means 14. The erroneous correction line retrieval device 1 can be composed of, for example, a host computer.

The input means 11 stores the file name of the source file on the magnetic tape device in which the source program before modification is stored, and the source program being modified which is being modified based on the source program before modification. The incorrect correction line search instruction including the file name of the source file on the magnetic disk device is input from the input device 2, and the source file before modification is converted from the source file according to the file name included in the incorrect correction line search instruction. It has a function of reading a program and a source program under modification and storing it in the memory 12.

In the remodeling source program that is being remodeled based on the pre-remodeling source program, an identifier indicating the type of remodeling is set in the remodeled line. In the present embodiment, it is assumed that the identifiers indicate three types of replacement of row contents, addition of rows, and deletion of rows (including the number of deleted rows). Also, the identifier is set by the program creator,
For example, when a source program is described in COBOL, an identifier is set in the first to seventh columns.

The comparing means 13 compares, for each of the lines stored in the memory 12 in which the identifier of the source program under modification is not set, with the corresponding line in the source program before modification, and compares the line which has not been compared. Is output to the output unit 14.

FIG. 2 is a flow chart showing a processing example of the input means 11, and FIGS. 3 and 4 are flow charts showing a processing example of the comparison means 13. The operation of this embodiment will be described below with reference to the drawings.

When the user checks whether or not there is a line in which the source program under remodeling is erroneously corrected, the source file (for example, source file 5-1) in which the source program before remodeling is stored. And the source file in which the source program under remodeling is stored (for example, source file 5-n)
The incorrect correction search instruction including the file name is input from the input device 2.

This erroneously corrected search instruction is received by the input means 11 in the erroneously corrected line search device 1.

When the input means 11 receives the erroneous correction search instruction, as shown in the flowchart of FIG. 2, the source file 5-1 is based on the file name of the source file 5-1 included in the erroneous correction search instruction. The pre-modification source program is read from and stored in the memory 12 (step S1), and then the source file 5-
The source program under modification is read from the source file 5-n based on the file name of n and stored in the memory 12 (step S2). Then, when the storage of the source program before modification and the source program under modification is completed, the input means 11 activates the comparison means 13 (step S
3).

FIGS. 5 and 6 are diagrams respectively exemplifying a source program before remodeling and a source program during remodeling input by the input means 11. In the case of this example, an identifier R indicating that the line contents have been replaced is set in the Nth line of the source program under remodeling shown in FIG. 6, and two lines are deleted from the N + 1th line in succession. The identifier D0002 indicating that the line is added, and the identifier A indicating that the line is an additional line is set in the (N + 2) th line. Further, in the source program during remodeling, “MOVE X TOZ” corresponding to the (N + 3) th line of the source program before remodeling is erroneously deleted.

When activated, the comparing means 13 sets the variable i indicating the line of interest in the source program before remodeling to “1” and sets the line of interest in the source program during remodeling as shown in the flowchart of FIG. Is set to "1" (step S11).

After that, the comparing means 13 pays attention to the first line of the source program under remodeling and judges whether or not the identifier is set (steps S12 and S14). If it is determined that the identifier has not been set, it is determined whether or not the first line of the source program being modified is a comment line (step S15). The type is determined (FIG. 4, step S19).

In the case of the example of FIG. 6, since the identifier is not set in the first line of the source program under remodeling, the judgment result in step 14 is NO, and the comparing means 13 determines the first line of the source program under remodeling. It is determined whether the line is a comment line (step S15).

If the first line of the source program being modified is a comment line, the comparing means 13 sets the value of the variables i and j to +1 and sets the line of interest to the source program before modification.
After the source program being modified is changed to the next line (step S18), the process of step 12 is performed. If the source program under modification is not a comment line, the comparing means 13 compares the contents of the first line of the source program before modification stored in the memory 12 with the contents of the first line of the source program under modification. Compare (step S16), and if the comparisons match (YES in step S17), step S
After performing the process of 18, the process returns to the process of step S12,
If the comparisons do not match (NO in step S17), the process of step S22 in FIG. 4 is performed.

In the example shown in FIG. 6, the first line of the source program being modified is not a comment line.
Performs the process of step S16, and
Since the contents of the first line of the source program before remodeling and the first line of the source program during remodeling are the same in the examples of FIGS. After changing both the program and the source program under modification to the next line (step S18), the process returns to step S12.

It is assumed that, for example, i = N and j = N are obtained by repeating the above processing. i = N,
When j = N, the comparing unit 13 looks at the Nth line of the source program being remodeled and determines whether or not an identifier is set on the Nth line of the source program being remodeled (step in FIG. 3). S12, S14).

In the case of the example shown in FIG. 6, since the identifier R is set in the Nth line of the source program being remodeled, the comparing means 13 determines the type in step S19 of FIG. Since the identifier R indicates the replacement of the line contents,
By setting i = N + 1 and j = N + 1, the comparing means 13 changes the line of interest to the next line (N + 1) for both the source program before remodeling and the source program during remodeling (FIG. 3, step S18). The processing of S12 is performed. That is, the Nth line of the source program being remodeled is a line in which the contents of the line have been replaced, and it is meaningless to compare the line with the corresponding line in the source program before remodeling. The means 13 sets the line of interest to the next line in both the source program before remodeling and the source program during remodeling.

When i = N + 1 and j = N + 1, the comparison means 13 focuses on the (N + 1) th line of the source program being remodeled and determines whether or not an identifier is set in that line (steps S12 and S14). ).

In the example shown in FIG. 6, since the identifier D0002 is set in the (N + 1) th line of the source program being remodeled, the comparing means 13 judges the type in step S19 of FIG. Since the identifier D0002 indicates deletion of two lines, the comparing means 13 determines the value of the variable i (N
By adding the number of deleted lines “2” to (+1) and i = (N + 3), the line of interest for the source program before remodeling is changed to the (N + 3) th line, and the current line in the source program being remodeled is focused on. Of the variable j indicating the row where
By adding 1 to 1 and setting j = (N + 2), the line of interest for the source program being remodeled is changed to the (N + 2) th line (step S21), and thereafter, step S1 in FIG.
Process 2 is performed. That is, since the (N + 1) th line and the (N + 2) th line in the source program before remodeling have been deleted in the source program during remodeling, the comparing means 13 sets the line of interest and the (N + 3) th line for the source program before remodeling. On the line, the source program being remodeled is on the (N + 2) th line.

When i = N + 3 and j = N + 2, the comparing means 13 pays attention to the N + 2th line of the source program under remodeling and judges whether or not an identifier is set in that line (steps S12 and S14). ).

In the case of the example of FIG. 6, since the identifier A is set in the N + 2th line of the source program under remodeling,
The comparing means 13 determines the type in step S19 in FIG. Since the identifier A indicates the addition of a line, the comparing means 13 increases the value (N + 2) of the variable j indicating the current line of interest in the source program under remodeling by +1 to j = N + 3. Then, only the line of interest for the remodeling source program is changed to the (N + 3) th line (step S20), and then the process of step S12 in FIG. 3 is performed. That is, the N + 2th line of the source program under remodeling is
Since the added line is insignificant even if the line is compared with the line in the source program before remodeling that is currently being focused on, the comparing means 13 sets the line to be focused only for the source program under remodeling. Change to the following line:

When i = N + 3 and j = N + 3, the comparing means 13 looks at the (N + 3) th line of the source program being remodeled and determines whether or not an identifier is set in that line (steps S12 and S14). ).

In the example of FIG. 6, since the identifier is not set in the (N + 3) th line of the remodeling source program, the comparing means 13 determines whether the (N + 3) th line of the remodeling source program is a comment line. (Step S1
5).

Since the (N + 3) th line of the remodeling source program is not a comment line, the comparing means 13 determines the contents of the (N + 3) th line of the pre-modification source program indicated by the variable i and the remodeling source program indicated by the variable j. Is compared with the contents of the (N + 3) th line.

The content of the (N + 3) th line of the source program before remodeling is “MOVE X TO Z”, and the content of the (N + 3) th line of the source program being remodeled is “MOVE M TOZ”.
Since the comparison result is a non-coincidence, the comparison means 13 causes the contents "MOVE X TO" of the N + 3th line of the source program before modification as shown in the flowchart of FIG.
Z ”, the line number (N + 3), and the contents“ MOVE M TON ”and the line number (N + 3) of the line N + 3 of the source program being remodeled are passed to the output means 14 (step S2).
2).

When the above information is passed from the comparing means 13, the output means 14 displays the information on the display device 3 and passes the above information to the printer 4 for printing. Users can look at this output to find out where the incorrectly modified line is in the source program being modified.

When the processing in step S22 is completed, the comparing means 13 searches the source program before remodeling and the source program under remodeling, respectively, and obtains the start line of the next section (step S23). In the case of the examples of FIGS. 5 and 6, the X-th line is obtained as the start line of the next section for the source program before remodeling, and the Y-line is obtained as the start line of the next section for the source program being remodeled. If you cannot find the start line of the next section after searching the source program before modification to the end, or you can find the start line of the next section even if you search the source program before modification to the end. If not (YES in step S24), the comparing means 13 ends the process.

When it is determined in step S23 that the start line of the next section of the pre-modification source program is the Xth line and the start line of the next section of the source program being modified is the Yth line, the comparing means 13 After setting i = X and j = Y
(Step S25), the process returns to step S12 in FIG. 3, and the same processing as described above is performed. Then, when the processing of the last line of the source program being modified ends (YES in step S13), the comparing unit 13 ends the processing. Here, if there is a mismatch between the source program before modification and the source program being modified, it is necessary to make the line of interest the start line of the next section for both the source program before modification and the source program being modified by deleting the line, This is to prevent the subsequent lines from being determined as non-coincident when an erroneous correction such as the addition of lines is performed that changes the number of lines.

It should be noted that in the above-described embodiment, the identifier indicating the deletion of the line is also shown as the number of deleted lines, but it is also possible to show only the deletion. In that case, an identifier indicating deletion is set for each of the deleted lines, and the comparing means 13 modifies the line of interest if the identifier indicating deletion is set for the current line of interest of the source program being altered. Only the middle source program should be on the next line.

[0053]

As described above, the present invention is determined based on the contents of the identifier in the source program under remodeling which is remodeled based on the source program before remodeling.
Equipped with a comparison means that compares the contents of the lines corresponding to the source program before modification and the source program under modification and outputs the information indicating the lines that do not match, so the erroneous correction lines of the source program being modified can be corrected in a short time. And there is an effect that can be accurately searched.

Further, according to the present invention, the identifier indicating the deletion of a line includes the number of deleted lines indicating the number of consecutive lines deleted from the line in which the identifier is set, and the comparison means is under modification. If the above line is set on the line of interest in the source program, the line of interest is changed by the number of deleted lines for the pre-modification program and changed to the next line for the source program being modified. During modification If the source program is modified by deleting a plurality of consecutive lines, the processing speed can be increased.

Further, according to the present invention, if a source program is divided into sections before and after remodeling, if a mismatch is detected, information indicating a mismatched line is output, and the line of interest is rewritten before the remodeling and the source being remodeled. Since the program is changed to the start line of the next section, if the erroneous correction is to change the number of lines such as deleting a line or adding a line, the line where the erroneous correction described above was performed This has the effect of preventing a situation in which the comparison results of all subsequent rows all become inconsistent.
