2. Description of the Related Art A method of generating a source from a list of logic diagram descriptions and compiling the source is disclosed, for example, in Japanese Patent Application Laid-Open No. H06-314193. Generates a list of source programs from a specification list in which the contents are described using a logical diagram, and compiles the source list generated from the specification list so that it can be performed more efficiently It discloses that when a compile error occurs, an error list is created in which corresponding parts of a specification list and a source list are arranged on one of the left and right sides and the other. That is, the debugging operation described in this publication is only an operation for dealing with a compilation error, and does not refer to a general debugging operation.

Japanese Patent Application Laid-Open No. 08-95762 discloses an error list output from a plurality of processors, and collectively displays errors from all processors for each text in a program specification. It is disclosed that it is possible to know at once a program specification editor for each text and how many errors have occurred in each text, and it is easy to determine how to correct the text. Have been.

Further, Japanese Patent Application Laid-Open No. 05-257733 discloses a method for debugging a program specification so that the execution position in the program specification can be accurately known in real time and the program specification can be debugged accurately. When converting a program specification on a terminal and creating a source program, a line number table indicating a correspondence relationship between a record number given to a record constituting the program specification and a line number given for each line of the source program. A program corresponding to the line number of the running source program, which is created, stored in an arbitrary storage device, receives the line number of the running source program transmitted by the host debugger in the terminal debugger, and refers to the line number table. Extract the record number of the specification, and from the record corresponding to the extracted record number, Acquires over data are disclosed to be displayed on the display device to edit.

By the way, regarding general debugging work,
In a conventional system that analyzes a source program generated by applying a generation rule to an input specification, there is no method for mechanically calculating the relationship between the analysis result on the source program and the position on the input specification, and a method for searching visually. There was only.

[0006]

However, this prior art has the following problems. The first problem is that if the specification needs to be corrected as a result of the analysis, the correction takes time. The reason is that the format of the input specification is generally different from the format of the source program, and the reason for obtaining the position on the input specification from the position on the source program is to perform a search including the peripheral part.

A second problem is that even if the position of the input specification is specified, there is no guarantee that it is correct. The reason is that there is no means for mechanically obtaining the correspondence between the position on the source program and the position on the input specification.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problem. Even when the information obtained from the analyzing means is only the line number of the source program, the position information of the input specification can be obtained and generated. If the program types are the same, simply prepare a rule to convert the position information of the input specification as a comment. Even if the source programs generated by applying the generation rules corresponding to different program patterns are different, It is an object of the present invention to provide a source program compatible display method capable of acquiring position information of an input specification by the same logic.

[0009]

In order to achieve the above object, a display method corresponding to a source program according to the present invention comprises: a generation rule storage means for storing a generation rule described in the form of a rule in which knowledge of specification rewriting is described; By reading the specification input from the input means and applying the generation rule stored in the generation rule storage means, a source program in which positional information on the input specification is inserted as a comment statement is generated and stored in the source storage means. When there is information to analyze a source program stored in the source storage unit according to an instruction from the source generation unit and the input unit and output the output to the output unit, the information is stored in the source storage unit. An analysis method that extracts the position information of the corresponding input specification from the comment sentence and outputs the position information and the analysis result as a pair to the output means. Characterized in that it comprises and.

[0010] Therefore, the source generating means reads the specification input from the input means and applies the generation rule stored in the generation rule storage means to thereby insert the source program in which the position information on the input specification is inserted as a comment sentence. The analysis means analyzes the source program stored in the source storage means in accordance with an instruction from the input means, and if there is information to be output to the output means, the analysis means analyzes the source program. The position information of the corresponding input specification stored in the file is extracted from the comment sentence, and the position information and the analysis result are paired and output to the output means. If only the line number is used, the position information of the input specification can be obtained, and if the generated program type is the same, the input specification Only by preparing rules for converting position information as comments, even if source programs generated by applying generation rules corresponding to different program patterns are different, the analysis means uses the same logic to analyze the position information of the input specification. Can be obtained.

[0011]

Next, an embodiment of a display method corresponding to a source program according to the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a first embodiment of a source program compatible display system according to the present invention. First, an outline of the first embodiment will be described with reference to FIG.

In FIG. 1, a source generation unit 103 reads an input specification input from an input unit 101 and outputs a source program to a source storage unit 105 in accordance with a generation rule stored in a generation rule storage unit 104. At this time, the source generation means 103 inserts the position information on the input specification as a comment sentence in the source program. The source generation means 103 and the generation rule storage means 10
4 constitute a generator 102 (generator engine).

The analysis means 106 analyzes the source program stored in the source storage means 105 in accordance with an instruction from the input means 101, and outputs the analysis result to the output means 1.
At the time of output to 07, the input specification position information is obtained from the comment sentence in the source storage means 105 and passed to the output means 107 together with the analysis result. Thereby, the user can easily deal with the analysis result on the input specification. In this manner, by converting the position on the source program into the position information on the input specification, the position of the analysis result on the specification can be mechanically identified.

Next, the configuration of the first embodiment will be specifically described. The generator 102 includes a source generation unit 103 and a generation rule storage unit 104,
These source generation means 103 and generation rule storage means 10
4 operate generally as follows. The generation rule storage unit 104 stores a generation rule in which the knowledge of rewriting specifications is described in the form of a rule. The source generation means 103 generates a source program by applying the generation rules stored in the generation rule storage means 104 to the input specification input from the input means 101, and generates the source program.
Output to 05.

The analysis means 106 analyzes the source program stored in the source storage means 105 in accordance with the instruction input from the input means 101, and outputs the result.
If there is information to be output to the
, The position information of the corresponding input specification is extracted from the comment sentence, and the position information and the analysis result are output as a pair to the output unit 107.

Next, the operation of the first embodiment according to the present invention configured as described above will be described with reference to FIGS. FIG. 2 shows an example of correspondence between input specifications and source codes. The input specification 202 in FIG. 2 is the SPD (Sturct
ured Programming Dialog). As can be seen from the position information 201 of the specification for the input specification 202 and the position information for the source program 204, ie, the line number 203, the position information 2 of the input specification 202
01 and the line number 203 of the source program 204 do not match.

The analysis means 106 includes a source program 204
The source program 204
Only the line number 203 of the input specification 202 has the information of the line number 203 which is the position information.
There is no way to ask. If the logic for generating the source program from the input specification 202 is fixed, the position information of the input specification can be obtained from the line number 203. However, since the logic for generating the source program is dynamically determined at the time of generating the source program according to the generation rules stored in the generation rule storage unit 104, the position information of the input specification 202 cannot be obtained from the line number 203.

Therefore, in the first embodiment, the following processing is performed. That is, source program 2
Reference numeral 06 denotes a source program generated by the generator 102 from the input specification 202 according to the first embodiment, and a comment starts with “;”. The position information 201 is input to the source generation means 103 together with the input specification 202. The generation rule stored in the generation rule storage unit 104 is a rule for converting the position information 201 of the input specification 202 into a comment of the source program 206. According to this generation rule, the source generation unit 103 causes the source storage unit 105 And outputs a source program 206 including a comment in which position information is embedded.

"010" in the source program 206,
Position information 2 by line number such as “030” or “050”
05 is a comment sentence included in the input specification 202 as position information. In this manner, in the source program 206, the comment including the position information 205 and the source code obtained by converting the input specification 202 are paired. Therefore, the position information corresponding to the source program 206 is 1
It can be obtained by analyzing the comment before the line.

Next, a specific example will be described. As shown in FIG. 3, for example, it is assumed that the analysis means 106 is a real-time debugger that monitors the status of the program in real time while actually operating the program.
As shown in FIG. 3, when the source code of the line number “100” has been analyzed, the analysis unit 106
That is, the position information “C” of the input specification is obtained from the comment of the line number “090”. By transmitting the position information "C" to the output unit 107, the analysis unit 106 can identify the position of the input specification corresponding to the source code currently being analyzed. In FIG. 3, “ELSEcall sub02” of the input specification 202 shown in FIG. 2 is added to the position information “C”.
In FIG. 3, this “call sub0”
“2” corresponds to “call sub02” of the source program 206 with the line number “100”.

As described above, in the first embodiment of the present invention, the position information 205 embedded as a comment in the source program 206 can be used to obtain the position information from the line number 205 of the source program 206. Therefore, even when the information obtained from the analysis function is only the line number of the source program, the position information of the input specification can be obtained. Also, since the rules for converting position information as comments are the same and the logic for obtaining position information from comment statements is the same, the rules for converting the position information of the input specifications as comments should be used when the types of generated programs are the same. By simply preparing, even if source programs generated by applying the generation rules corresponding to different program patterns are different, the analysis means can acquire the position information of the input specification by the same logic.

Next, a second embodiment of the present invention will be described. FIG. 4 is a block diagram showing the configuration of the second embodiment. The second embodiment shown in FIG. 4 includes an input unit 401, a generator 402, a source storage unit 405, an analysis unit 406, an output unit 407, and an analysis result storage unit 408. The generator 402 includes a source generation unit 403 and a generation rule storage unit 404. In the second embodiment shown in FIG. 4, an analysis result storage means 408 is newly added to the configuration of the first embodiment shown in FIG.

The analysis means 406 temporarily stores the result of analyzing the source program stored in the source storage means 405 in the analysis result storage means 408. In accordance with an instruction from the input unit 401, the analysis unit 406 passes the analysis result stored in the analysis result storage unit 408 and the position information obtained therefrom to the output unit 407.

Next, a specific example will be described. Consider a case where the analyzing means 406 is a syntax checker for detecting a syntax error in a source program. Since the syntax checker checks the source program to be analyzed in a batch, there may be a plurality of analysis results. In such a case, FIG.
Since the information cannot be output line by line together with the input specification position information, the information is temporarily stored in the analysis result storage means 408.

After the check, for example, input means 401
If the instruction is a batch output, the processing for obtaining the corresponding input specification position information from the analysis result is performed by the analysis result storage unit 40.
The analysis is performed on all the analysis results stored in 8 and all pairs are sent to the output unit 407 collectively. The second embodiment shown in FIG. 4 corresponds to batch analysis, and the first embodiment shown in FIG. 3 corresponds to real-time analysis.

[0026]

As described above, according to the present invention, the first effect that the position information of the input specification can be obtained even when the information obtained from the analysis function is only the line number of the source program. The reason is that the position information embedded as a comment in the source program can be used to obtain the position information from the line number of the source program. In addition, when the generated program types are the same, only the rules for converting the position information of the input specifications as comments are prepared, and the source programs generated by applying the generation rules corresponding to the different program patterns are different. Also, the second effect is obtained that the analyzing means can acquire the position information of the input specification by the same logic. The reason is that the rules for converting the position information as a comment are the same, and the logic for obtaining the position information from the comment text is also the same.
