Abstract

PURPOSE:To execute program conversion among many languages through an assembling text in a common state by loading an analysis module and a formation module previously formed in accordance with conversion specifying parameters (converting language and converted language). CONSTITUTION:An analyzing part 3 executes the character/phrase analysis, syntax analysis and meaning analysis of an inputted source program and forms a decomposing text 6. A conversion part 4 executes conversion processing independent of the language of an object to be converted by inputting the text 6 and executing the conversion processing on the basis of the key information of a dictionary file 7 and forms an assembling text in a so-called common format. A forming part 5 inputs the test 8, executes name formation, data formation and syntax formation processing and forms a converted source program.

[Detailed Description of the Invention] [Summary] Regarding a multilingual processing converter that converts programs between multiple languages, an analysis module and a generation module are created in advance for each language, and a module corresponding to the specified language is created. an analysis module that loads an analysis module corresponding to the specified language and generates a decomposed text from the input program; A conversion unit that generates an assembled text from this disassembled text by referring to a dictionary file, and a generation unit that loads a generation module corresponding to an instructed language from this assembled text and generates a corresponding prora E, It is configured to convert an input program into a program in a specified language and output it.

(Field of Industrial Application) The present invention relates to a multilingual processing converter that converts programs between multiple languages.

[Problems to be solved by the conventional technology and the invention] When converting sources from different programming languages, as shown in Figure 3, source converters are dedicated to the source language and destination language, respectively. must be developed. Therefore, if the language to be converted changes, a source converter must be created or a new one must be developed, which requires a large amount of development man-hours to develop source converters for a wide variety of programming languages. There was a problem with this.

The purpose of the present invention is to create an analysis module and a generation module for each language in advance, load the modules corresponding to the designated languages, and perform conversion into any different language via a common interface. It is said that

[Means for solving problems]

Means for solving the problem will be explained with reference to FIG.

In FIG. 1, the analysis section 3 is loaded with an analysis module corresponding to the designated language and generates decomposed text 6 from the input program.

The converter 4 refers to the dictionary file 7 and generates an assembled text 8 from the decomposed text 6 in a standardized format (interface) that does not depend on the language to be converted.

The generation unit 5 is loaded with a generation module corresponding to the specified language, and generates a blog in the specified language from the assembled text 8 in a standardized manner.

[Effect]

In the present invention, as shown in FIG. 1, an analysis section 3 loaded with an instructed analysis module analyzes a human-powered program to generate a decomposed text 6, and a conversion section 4 refers to a dictionary file 7. Then, a common fi-like assembly text 8 is generated from this disassembled text 6, and the generation unit 5 loaded with the instructed generation module generates a program in the specified language from this advanced text 8. I have to.

Therefore, analysis modules and generation modules corresponding to various languages are created in advance, the module corresponding to the specified language is loaded, and the specified language is created via the assembly text 8 in a standardized manner. By converting the program into a program, it becomes possible to easily convert the program between arbitrary languages.

〔Example〕

Next, the configuration and operation of one embodiment of the present invention will be explained in detail using FIGS. 1 and 2.

In FIG. 1, a source converter 1 includes a control section 2, an analysis section 3, a conversion section 4, and a generation section 5, and converts an input source program into a source program in another language.

The control unit 2 performs various controls so that the system operates under different systems and environments. For example, a variable + A Jet that analyzes the indicated parameters (source language, destination language, e.g. A language → C language, etc.), loads the corresponding analysis module and generation module, and passes control to them. It is.

The analysis unit 3 performs lexical analysis of the input source program,
It performs syntactic analysis and semantic analysis to generate decomposed text 6. This is because the description format, data usage, and meaning differ depending on the language in which the source program is written, so the module that includes lexical analysis, syntactic analysis, and semantic analysis is shown in A as shown in the dotted rectangle in the figure. Language analysis module 3-1, B language analysis module 1-2,...N
HE Oi# L in advance as language analysis module 3-N
, and load and use the one corresponding to the specified conversion source language each time.

The conversion unit 4 is designed to perform conversion processing independent of the language to be converted, and uses the decomposed text 6 as human power to perform conversion processing based on the key information (μ) of the dictionary file 7, so to speak. This is to generate an assembled text 8 in a converted form.

The generation unit 5 receives the assembled text 8 as input, performs name generation, data generation, and syntax generation processing, and generates a converted source program.

This is because the description format, data usage, and meaning differ depending on the language of the source program to be converted, so the module that includes name generation, data generation, and syntax generation is enclosed in a rectangle using dotted lines in the figure. A language generation module 5-1, B language generation module 5-2, . I try to load it and use it.

Next, the operation of converting the A language into the C language will be explained using symbols 1 to 2 in FIG.

In FIG. 1, ■ in the figure indicates that "conversion from A language to C language" has been input to the control unit 2 constituting the source converter 1 as a conversion instruction parameter. The unit 2 loads the A language analysis module 3-1 into the analysis unit 3, and loads the C language generation module 5-3 into the generation unit 5.

In the figure, ■ indicates that the source program in language A is input to the analysis section 3.

In the figure, ■ indicates that the language analysis module 3-1, which has been loaded into the analysis unit 3 and given control, performs lexical analysis, syntactic analysis, and semantic analysis of the input A language source program and decomposes the text. 6 is generated and output to a file.

In the figure, ■ indicates that the decomposed text 6 is input to the converter 4.

In the figure, ■ indicates that the conversion unit 4 performs a conversion process based on the key information read from the dictionary file 7, and generates the assembled text 8 in a so-called common form.

■ in the figure indicates that the generated assembled text 8 is output to a file.

In the figure, ■ indicates that the assembled text 8 is input to the generation unit 5.

In the figure, ■ indicates that the C language generation module 5-3 takes the assembled text 8 as input, generates a name, generates data, generates a syntax, and outputs a C language source program created to a file.

As described above, the analysis module and generation module created in advance corresponding to the conversion instruction parameters (conversion source language, conversion destination language) are loaded, and the assembly text 8 in a standardized manner is used. By converting to a different language, source conversion between multiple languages can be easily performed.

Next, the case of converting from FTL (Fujitsu's original language) to C0BOL will be specifically explained using FIG.

For example, the source program written as FTL on the left side is “
The source program with the data name “I FLD n TYPEj” is the FTL loaded into the analysis unit 3 in Figure 1.
The illustrated decomposition text 6-1 is generated by the analysis module. This decomposed text 6-1 includes NAME text, data definition text!, as shown in the figure.・It consists of data type text, level text, etc. The "data name 10", 'FLD', etc. written in the rectangles corresponding to each of these texts are obtained by the FTL source program through lexical analysis, syntactic analysis, and semantic analysis. "Data name 1" and the like are each pointed to from each text.

The assembly test (toss) 8-1 is the result of the conversion at 110 and 1 by the converting section 4 in FIG. As shown by the dotted line arrows in the figure, this is a modified text 1i that is made to correspond to each text in a common manner.

“On data name I PICTUREN (
1), “(The leading “O” is a number zero) is a source program written in C0n0L generated by the COB OL generation module loaded into the diagram generation unit 5. , the C0n0L generation module receives the assembled text 8-1 as input and generates a name, data, and syntax.

〔Effect of the invention〕

As explained above, according to the present invention, analysis modules and generation modules corresponding to languages are created and prepared in advance, and analysis modules and generation modules corresponding to the conversion source and conversion destination languages in the conversion instruction parameters are created and prepared in advance. Since a configuration is adopted in which a converted program is created in a common manner independent of languages by loading each language, programs can be easily converted between multiple languages. This reduces the number of man-hours required to develop a dedicated source converter for each language to be converted.
