Abstract

PURPOSE:To facilitate the support of plural code schemes in a single system by attaining the succession of information on the code systems in the form of a common interface between an applied program and a library, etc., developed as a separate product. CONSTITUTION:A code scheme setting area 11 serves as a storage area which stores the type of the code scheme which is presently treated. A code scheme set-up processing part 12 sets the type of the code scheme at the area 11, and a code scheme reference processing part 13 reads out the type of the code scheme out of the area 11. A master applied program 14 calls the part 12, and a slave applied program 15 calls the part 13. Then, the type of the code scheme treated by the program 14 is succeeded via the area 11, and one of plural code schemes is processed. As a result, plural code schemes can be easily supported by a single system. Then the productivity, the interchangeability, and the maintainability, etc., are improved for various libraries, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION [Summary] This invention relates to a processing method for supporting multiple code systems in a single system in a computer system in which a parent application program and a child application program called from the parent application program handle multiple code systems.

Transfer code information between application programs and libraries developed as separate products.

By realizing it as a common interface.

The purpose of this is to facilitate the support of multiple chord systems in a single system.There is a chord system setting area that stores the type of chord system currently being handled, and a code that sets the type of chord system in this chord system setting area. system setting processing means; and a code system reference processing means for reading out the type of code system set in this code system setting area; in the parent application program, the code system setting processing means is called; By calling the code system reference processing means, processing for one code system among a plurality of code systems is performed.

[Industrial application field]

The present invention relates to a processing method for supporting multiple code systems in a single system in a computer system in which a parent application program and child application programs called from the parent application program handle multiple code systems.

[Conventional technology]

FIG. 3 shows an example of the conventional method.

Conventionally, one application program was generally capable of processing only one code system. However, there is a demand for application programs that can handle multiple code systems, and it is being considered to be able to handle multiple code systems in a single system.

In such a system, 3 For example, a FORTRAN application program that operates on a system where multiple code systems exist.
4, as shown in FIG. 3, determines its own chord system through process 5 (2). and.

If various library calls are required, carefully select the appropriate library 35 that handles the code system (■), and call that library 35 (processing ■).
.

The called library 35 processes the library according to process 3, and if it is necessary to output one character string,
Outputs character strings of own code (processing ■). After these processes are completed, the process returns to the calling source.

The FORTRAN application program 34 that is the calling source performs character string output (processing ■) as necessary.

[Problem to be solved by the invention]

In general, conventional methods have a problem in that the code system that can be handled by each application program is fixed, resulting in a code system that is closed to each application program. Furthermore, even if the parent application program determines the code system, a library 35 must be prepared for each code system, and if you try to output a string with a library 35 that supports only a single code, 5. Since the character string may not match the character string output by the parent FORTRAN application program 34, there is a problem that it is necessary to change the character string in advance to generate an error.

In addition, various mathematical function libraries may be used in FORTRAN application programs 34, etc., but since these are often developed and provided as separate products, there may be differences between parent and child programs.

Having individual interfaces for handling code systems also had the problem of poor productivity and maintainability.

The present invention aims to solve the above problems, and includes an application program and
The purpose is to facilitate the support of multiple code systems in a single system by realizing the inheritance of code system information between libraries and the like developed as separate products as a common interface.

[Means to solve the problem] FIG. 1 is a diagram showing the principle configuration of the present invention.

In this system, the parent application program 14.

A child application program 15 called from this parent application program 14 is configured to operate.

The parent application program 14 or the child application program 15 is configured to handle multiple code systems.

The chord system setting area 11 is a storage area for storing the type of chord system currently being handled, and is provided in a predetermined common AiJI area managed by the system.

The chord system setting processing section 12 performs processing for setting the type of chord system in the chord system setting area 11. The code system reference processing unit 13 performs a process of reading out the type of code system set in the code system setting area 11.

In the parent application program 14, the code system setting processing section 1
2 and calls the code system reference processing unit 13 in the manual application program 15 to inherit the code system fff[ handled by the parent application program 14 via the code system setting area 11, and Processing is performed for one code system in the system.

[Effect]

The parent application program 14 uses the code system setting processing unit 12 to set information indicating which code system is being operated in a code system setting area 11 provided in a system common area or the like.

When the manual application program 15 is called from the parent application program 14, the code system reference processing section 13 allows the manual application program 15 to know the code system handled by the parent application program 14, which is set in the code system setting area 11. As a result, the character string output by the parent application program 14 and the manual application program 1
It is possible to match code systems such as character strings output by 5.
