Abstract

PURPOSE:To attain the automatic conversion of a source program by performing the source conversion as necessary based on the retrieving result of a conversion information data base and outputting the result of the source conversion to an output file. CONSTITUTION:A source input means 2 reads the source record out of a file which stores a source program performing the transplantation. Then a source decomposing means 3 decomposes the source record read by the means 2 into each word. A retrieving means 4 retrieves a conversion information data base 5 as long as the word decomposed by the means 3 seves as a key word for the source conversion. A source conversion means 6 discriminates whether the source conversion is required or not based on the retrieving result of the base 5 obtained by the means 4. When the source conversion is required, the means 6 carries out the source conversion. Then a source output means 7 outputs the source record received from the means 6 to an output source file 8. Consequently, the source program is automatically converted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a source program conversion method, and particularly to a source program conversion method for porting a program between different operating systems (hereinafter abbreviated as O8).

[Conventional technology]

Conventionally, methods for converting source programs (hereinafter simply referred to as source conversion) when porting programs between different O3s include methods that manually judge each step of the source program and convert the source, and There was a method of automatically converting sources using a source conversion program that incorporated conversion information.

(Problems to be Solved by the Invention) In the conventional source program conversion method described above, if the source steps are manually determined and converted when a program is ported between different O3s, it takes a long time to convert the source. The drawback is that it takes a lot of time and there is a high possibility that conversion errors will occur.

In addition, if source conversion is performed using a source conversion program that has conversion information within the program, manual errors are eliminated, but since the conversion information is included in the source conversion program, it is necessary to add, modify, and edit the conversion information. This method has the disadvantage that when a deletion or the like occurs, the source conversion program must be modified and tested.

In view of the above-mentioned points, an object of the present invention is to perform source conversion by using a source conversion program that incorporates conversion information into the program, instead of converting the source manually when converting programs between different O8s. The object of the present invention is to provide a source program conversion method that realizes automatic conversion of source programs.

[Effect]

In the source program conversion method of the present invention, a source input means reads a source record from a file in which a source program to be ported is stored, a source decomposition means decomposes the source record read by the source input means into words, If the word decomposed by the source decomposition means is a keyword for source conversion, the search means searches the conversion information database, and the source conversion means performs source conversion based on the search result of the conversion information database by the search means. It is determined whether or not conversion is necessary, and if conversion is necessary, the source is converted, and the source output means outputs the source record passed from the source conversion means to an output file.

Determine whether an input failure occurred when reading.

As a result of the judgment, if an input failure occurs, the process ends (
Abnormal termination> 0 Next, it is determined whether or not the source record has ended, and if the source record has ended, the process terminates normally. If there is neither an input error nor the end of the source record, it is determined whether the read source record is a comment, a blank, etc., or actual coding. If the source record is not actual coding, the next source record is read, and if the source record is actual coding, this source record 204 is passed to the source decomposition means 3.

Source record 20 sent from source input means 2

Based on 04, it is determined whether the word information that has been decomposed and sent is a keyword or item name for source conversion, and decomposition information 306 is created. Created disassembly information 306
is sent to the search means 4.

The decomposition information 306 created by the source decomposition means 3 is sent to the retrieval section 402 of the retrieval means 4. In the search unit 402,
The sent decomposition unit [306] looks at the information such as keywords or item names added by the source decomposition means 3, and if there is a keyword for source conversion, converts the conversion information database 5 based on that information. search for. If there is no keyword for source conversion, it is determined that the source record does not require conversion. The search results of the conversion information database 5 are as follows:
It is passed to the determination unit 404. In the determination unit 404, when a plurality of pieces of conversion information are found for a certain keyword as a result of searching the conversion information database 5, the determination unit 404 determines which conversion information applies to the word order rules and code rules of the words in the conversion information. The result of the 0 determination based on information such as [0] is passed to the district department 405. &I collection unit 405 is the determination unit 40
As a result of the judgment in step 4, the applicable conversion information is divided into decomposition information 40.

The decomposition information 406 sent from the search means 4 is sent to the judgment section 502 of the source conversion means 5.The judgment section 502 looks at the conversion information added by the search means 4 and determines what kind of conversion to perform. judge. The editing unit 503 performs the conversion specified by the conversion information (for example, conversion to a comment line) based on the word information in the decomposition information 406, and creates a source record 504 to be output to the output tooth file 8.

The source record 504 created by the source conversion means 6 is sent to the output section 602 of the source output means 7. The output unit 602 outputs the sent source record 504 to the output tooth file 8. Further, the determination unit 604 determines the output status when the source record 504 is output to the output tooth file 8. If an output failure occurs, it is assumed that an abnormality has occurred and the processing is terminated. If there is no abnormality, control is passed to the source input means 1 to read the next source record.

〔Effect of the invention〕

As described above, the present invention has the advantage that source conversion can be performed in a short time and conversion errors are less likely to occur by automatically performing source conversion instead of manual conversion processing.

In addition, by storing conversion information in the conversion information database, the source conversion program itself can be corrected and tested when conversion information is added, modified, deleted, etc., as in conventional source conversion programs. This is not necessary, and the effect is that adding, modifying, deleting, etc. of conversion information can be done by simply updating the contents of the conversion information database.
