Abstract

PURPOSE:To sufficiently execute the conversion and the check without allowing a person's help to intervene, and also, to execute the transplantation of a modified part without a problem by providing a program separate rule data base, an operating system separate rule data base, and a means for detecting a limit violation in a source program. CONSTITUTION:The subject system is provided with an operating system separate rule data base 4 in which a conversion rule and a limit rule of every operating system are stored, a program separate rule data base 3 in which a conversion rule and a limit rule of every source program are stored, and based on a conversion rule 8 and a limit rule 10 of both the rule data bases, the conversion of the source program and the check of the limit violation are executed. Accordingly, since they are executed without a person's help, an artificial miss is avoided. In such a way, even at the time of transportion of a modified part, the conversion and the check can be executed efficiently.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a source program porting method for porting a source program running on one operating system to another operating system.

[Conventional technology]

It is often the case that the operating system, which is the environment in which the source program is executed, is changed while the functionality of the source program remains the same. In this way, converting a source program that runs on one operating system into a format that can be executed on another operating system is called porting.

Conventionally, in this type of source program porting method,
We have created a rule database for each operating system that stores conversion rules for each operating system (such as rules for converting data with different binoto configurations) and restriction rules (such as rules for checking whether the conversion is normal). Based on this, the source program is converted to a format compatible with the destination operating system, and restriction rules are used to check whether there are any violations.

[Problem to be solved by the invention]

Conventionally, porting of source programs has been carried out as described above, but converting and checking source programs requires information specific to the source program, such as information specific to the language in which it is written, so it requires manual intervention. There are parts that require intervention, which has the disadvantage that there is a risk of artificial errors such as omissions in conversion and failure to detect restriction errors.

In addition, if after porting a new source program, the original source program is partially modified and only the modified part is ported, information specific to the source program regarding the modified part is newly required. Therefore, it takes a lot of time and effort to perform sufficient conversion and checking, which has the drawback of poor working efficiency. It is also possible to transplant the entire system to a new one, including the parts that have not been modified, but this would result in a significant drop in efficiency.

The present invention has been proposed in view of the above points, and its purpose is to be able to perform sufficient conversion and checking without human intervention, and to also be able to transplant modified parts without any problems. The objective is to provide a source program porting method.

[Means to solve the problem]

In order to achieve the above object, the present invention includes: a rule database for each program that stores conversion rules and restriction rules for each source program; a rule database for each operating system that stores conversion rules and restriction rules for each operating system; and search conditions. A search condition setting means for setting search conditions such as conversion source and destination operating system names and program IDs of source programs using cards, etc., and searching both rule databases and inputting and outputting data according to the set search conditions. database access means; source program conversion means for converting the source program using conversion rules retrieved from both rule databases; and restrictions in the source program using restriction rules retrieved from both rule databases. A restriction violation detection means for detecting a violation is provided.

[Effect]

In the source program porting method of the present invention, the search condition setting means sets search conditions such as the conversion source and destination operating system names and the program ID of the source program according to the search condition card etc. Accordingly, the database access means searches and inputs/outputs data between a program-specific rule database storing conversion rules and restriction rules for each source program and an operating system-specific rule database storing conversion rules and restriction rules for each operating system; The source program conversion means converts the source program using the conversion rules retrieved from both rule databases, and the restriction violation detection means detects restriction violations in the source program using the restriction rules retrieved from both rule databases. conduct.

〔Example〕

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

FIG. 1 does not show an embodiment of the source program porting method of the present invention, but shows the constituent countries. In FIG. 1, this example shows the following:
A rule database 3 for each program and a rule database 4 for each operating system that store conversion rules and restriction rules, and a search condition setting means 5, a database access means 6, a source program conversion means 7, and a restriction violation detection means 9 as functional parts. We are prepared.

Note that the input source program l is a source program to be converted to another operating system,
The output source program 12 is a converted source program. The functions of each part are as follows.

Program-specific rule database 3: This is a database that stores conversion rules and restriction rules for each source program handled, and is unique to the input source program I created by the porter when porting a new port.
For example, information specific to the language used to describe the input source program 1 is included.

Operating system-specific rule database 4: This is a database that stores conversion rules and restriction rules for each operating system.

For example, it includes information necessary for conversion between data with different bit configurations.

Search condition setting means 5; has a function of receiving information such as the names of the conversion source and destination operating systems and the program ID of the input source program 1 using the search condition card 2, and setting these as search conditions.

Database access means 6; has the function of searching the program-specific rule database 3 and the operating system-specific rule database 4 and inputting/outputting data according to the search conditions set by the search condition setting means 5.

Source program conversion means 7; has a function of converting the human source program 1 using the conversion rules 8 retrieved and obtained from both rule databases 3.4 by the database access means 6, and generating the output source program 12. ing.

Restriction violation detection means 9; detects restriction violations in the human source program 1 using the restriction rules 10 retrieved and obtained from both rule databases 3.4 by the database access means 6, and creates a restriction error list showing details of restriction errors. It has a function of outputting 11.

Next, the operation of the above embodiment will be explained along the flowchart of FIG.

First, the search condition setting means 5 inputs information such as the names of the conversion source and destination operating systems and the program ID of the human source program 1 from the search condition card 2, and sets database search conditions from these (
Step S1).

Next, the database access means 6 searches for conversion rules from the program-specific rule database 3 that stores various rules for each source program and the operating system-specific rule database 4 that stores various rules for each operating system, according to the set search conditions. A search is performed (step 32).

Subsequently, the source program conversion means 7 converts the input source program l into a format compatible with the destination operating system according to the searched and acquired conversion rule 8, and generates the output source program 12 (step S3
).

Next, the database access means 6 accesses the program-specific rule database 3 and the operating system-specific rule database 4 according to the already set search conditions.
A search for restriction rules is performed from (step S4).

Then, the restriction violation detection means 9 detects a restriction error in the human source program 1 based on the retrieved and acquired restriction rule 10 (step S5).

At this time, details of the limit error are output to the limit error list II.

〔Effect of the invention〕

As explained above, in the source program porting method of the present invention, in addition to a rule database for each operating system that stores conversion rules and restriction rules for each operating system, conversion rules and restriction rules for each source program are stored. A rule database is set up for each program, and source programs are converted and checked for violation of restrictions based on the conversion rules and restriction rules of both rule databases. Mistakes can be avoided.

■Efficient conversion and checking can be performed even when porting modified parts.

There are other effects.
