Abstract

PURPOSE:To easily proceed with source program correcting work by displaying information concerning an error from the position of a line next to the line with the error in the case of existing the sentence of a syntax error. CONSTITUTION:A message burying processing part 5 inputs error information in an error information file 9 and a source program corresponded by an input source file 8. The number of necessary lines is additionally ensured after the pertient line of the source program based on a line number in error information and the piece of error information is buried into the ensured line with respect to all the pieces of error information. Next, the source program into which error information is buried is registered to a message burying source file 10 to activate an editor part 6. The activated editor part 6 inputs the source program into which error information is buried from the message burying source file 10 so as to display it on a screen. Then error information is retrieved to correct the source program.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for modifying a source program, which is used to modify the source program while linking a diagnostic program and a text editor when editing the source program and correcting errors. .

[0002]

2. Description of the Related Art Conventionally, as a correction method of this kind, JP-A-61-75435 or JP-A-03-
There is one disclosed in Japanese Patent No. 70033.

The one disclosed in Japanese Patent Application Laid-Open No. 61-75435 (Title of the Invention: Synchronous checker and text editor interlocking system) shows the syntax check result of the source program as shown in the display screen example of FIG. It is taken over by the editor, the error position is indicated by the cursor A, and the error type (error message) is displayed in the lower column B.

The one disclosed in Japanese Patent Laid-Open No. 03-70033 (title of the invention: compiler editor interlocking method) determines the type of error location by the screen division function of the editor, as shown in the display screen example of FIG. It is divided into an error display portion C displayed for each line number and a display portion D of the source program edited by the editor, and the error portion and its content and the source program are displayed on one screen.

[0005]

However, in the above-mentioned conventional technique, the former searches for an error part in the order of the line number of the source program when the source program is edited. You need to scroll to the last line,
There was a problem that the operation was troublesome.

Further, the error message is displayed only on the line indicated by the cursor A. For a command statement related to another statement such as a loop statement or a subroutine statement, an error of a plurality of statements is displayed on only one screen. I can't see the message,
There was a problem that work efficiency was poor.

In the latter case, the screen division function of the editor allows
Multiple lines of error messages can be viewed simultaneously on one screen, but the divided error message display screen C and the display portion D of the source program cannot be scrolled at the same time, and the error message display screen C and the source program are not displayed. There is a problem that the error content must be confirmed by alternately operating the display portion D.

There is a problem that the error message and the error line cannot be confirmed at the same time.

An object of the present invention is to provide a method of correcting a source program which can confirm an error message and an error line at the same time and easily correct the source program.

[0010]

To achieve the above object, the present invention is characterized in that, in displaying a source program to be corrected, information on a syntax error is displayed from the next line position where the syntax error occurs. To do.

[0011]

According to the above means, when there is a syntax error sentence, information about the error is displayed from the line position next to the line having the error.

Therefore, the error line and the information relating to the error can be grasped at once, and since only the operation is performed on the same screen, the correction work of the source program can be easily carried out.

[0013]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a system configuration diagram showing an embodiment of the present invention.

The system of this embodiment is roughly composed of a central processing unit 1, an input / output unit 2 and a storage unit 3.

Among them, the central processing unit 1 is activated through the input / output unit 2 to check the syntax of the source program, and generate a syntax error message for a line having a syntax error and store it in the diagnostic program unit 4. When,
A message embedding processing unit 5 for embedding the accumulated syntax error message in a corresponding syntax error line in the source program when activated from the diagnostic program unit 4;
The source program in which the syntax error message is embedded is displayed on the screen by the activation from the message embedding processing unit 5, and the syntax error message is embedded by the editor unit 6 that accepts the correction of the syntax error line and the activation from the editor unit 6. And an update processing unit 7 that deletes the syntax error message from the corrected source program and updates the source program having the syntax error to the corrected source program.

The storage device 3 has an input source file 8 for storing a source program, an error information file 9 for storing the result of the diagnostic program section 4, and a message embedding source for storing the result of the message embedding processing section 5. A file 10 and a modified source file 11 for storing the result of the editor unit 6 are provided.

FIG. 2 is a diagram showing the record structure of the error information file 9, where line number 21 and column position 2 are used.
2, message number 23, and message text 24.

FIG. 3 is a flow chart showing the flow of processing of this embodiment. The operation will be described below according to this flowchart.

First, the diagnostic program section 4 is loaded into the central processing unit 1 according to a user's instruction from the input device 2.

When the diagnostic program section 4 is activated,
The diagnostic program unit 4 inputs the source program specified by the user from the input source file 8 in the storage device 3, and checks the syntax of all the command statements of the input source program.

When the diagnostic program unit 4 detects a syntax error in the command statement of the source program, each time it detects the error, one record of error information consisting of the line number 21, column position 22, message number 23, and message text 24 in FIG. Is created, registered in the error information file 9, and the message embedding processing unit 5 is activated (step 31).

The message embedding processing unit 5 inputs the error information in the error information file 9 and the corresponding source program in the input source file 8, and determines the required number of lines of the source program based on the line number 21 in the error information. The error information is additionally secured after the relevant line, and the error information is embedded in the secured line for all the error information. When all the error information has been embedded, the source program with the embedded error information is embedded with a message. The source file 10 is registered and the editor unit 6 is activated (step 32).

The activated editor unit 6 inputs the source program in which the error information is embedded from the message embedded source file 10 and displays the input source program on the screen. The user corrects the source program while searching the error information of the source program in which the displayed error information is embedded, and when the correction is completed, the corrected source program in which the error information is embedded is corrected to the source file 11 after correction. Register and start the update processing unit 7 (step 33).

The update processing unit 7 uses the corrected source file 11
Input the modified source program in which the error information is embedded from, delete all the embedded error information from the input modified source program, and enter the modified source program in which the error information is deleted in the input source file Register at 8. At this time, the corresponding old source program is deleted (step 34).

FIG. 4 shows an example of a screen display when a processed program in which an error message is embedded in a source program is modified / edited.

In the figure, E indicates a source program display portion in the processed source program, F indicates an error message display portion embedded in the processed source program, and G indicates a user in the processed source program. In the error indicator that informs you of the embedding part of the error message, "$$$ cchk msg #:"
It is represented by.

H represents a line number in the source program where an error occurs, I is an error message number for notifying the user of an error message as a number, J is the number of errors in the source program, K is a message level, and L is an error. The message text showing the message content is shown.

As described above, by embedding error information in a source program, correction / editing can be processed simultaneously while viewing the error content of the source program on the same screen, so that correction / editing can be performed efficiently and easily. You can edit.

Particularly, it is extremely effective in a system in which the editor section does not have a screen division function.

In the present embodiment, after the correction in the editor unit 6 (step 33) is completed, the update processing unit 7 updates the source file (step 34) to delete the corresponding old source program and to display the error information. Although the corrected source program deleted from is registered in the input source file 8, it is corrected after the correction in the editor unit 6 (step 33) and before the update of the source file in the update processing unit 7 (step 34). A process may be provided in which new and old sentences are displayed in pairs for each of the generated sentences and a final confirmation is made as to whether or not the correction is correct.

Further, in the present embodiment, the update processing unit 7 completes the update of the source file (step 34). However, without ending this, the source program diagnosis (step 31) in the diagnostic program is continued. The source program may be diagnosed by branching.

[0033]

As described above, according to the present invention, the line number and the error message are displayed at the line number position corresponding to the error location detected by the diagnostic means for performing the syntax check for the source program displayed on the display screen. Since it is embedded and displayed, the error message and error line can be checked at the same time, and the source program can be easily modified.Because only the operation is on the same screen, you can easily proceed with the modification work. You can
