[Industrial application field]

The present invention relates to an information sharing processing method in a data processing device, and more particularly to an information sharing processing method in a data processing system including a plurality of data processing devices that use one or more codes to represent information.

In the data processing system, information such as character data is represented by, for example, a code associated with each character. There are several types of this code that have different representation formats, such as the ASCII code and EBCDIC code in the character data code.

[Conventional technology]

Information represented by a certain code has no meaning in a data processing device that employs another code as it is.

However, in reality, while various codes are used, data or programs, that is, information is often shared among a plurality of data processing devices.

Therefore, information represented by a certain code is converted into information represented by another code.
This conversion processing is performed by, for example, a code converter (means).

[Problems to be solved by the invention]

In the above-mentioned conventional technique, in order to perform the conversion process, the programmer / operator or the like needs to give an instruction to that effect. Further, for that purpose, it is necessary to be aware of the code used for expressing the information, and be aware of the code adopted by the data processing device which is going to use the information. Furthermore, since such caution is required, the processing tends to be complicated.

As described above, conventionally, in a data processing system in which a plurality of codes may be used inside, when using certain information, it is necessary to perform a code-conscious process, and the process is It was a heavy burden on the programmer / operator.

An object of the present invention is to provide an information sharing processing method in a data processing system in which information is held and shared so that the information can be used without being aware of the code.

[Means for Solving Problems] FIG. 1 is a principle configuration diagram of the present invention, showing a data processing system according to the present invention.

In FIG. 1, 1 and 2 are data processing devices, 3 is a storage device shared by the data processing devices 1 and 2, 31 to 33 are storage areas for holding predetermined information, and 41 and 42 are operating systems (hereinafter OS), 5 is storage area 31
The setting section 6 for setting information to be held in the storage areas 31 to 33 is a reference section for referring to the information stored in the storage areas 31 to 34.

The OS 41 of the data processing device 1 adopts (supports) one code (A code) as a code for expressing information. Therefore, the information created, developed, or used in the data processing device 1 is expressed using the A code (hereinafter referred to as the information depending on the A code).

The OS 42 of the data processing device 2 uses a code different from the A code (B
Code) is adopted (supported). Therefore, the information for the data processing device 2 is information that depends on the B code.

The storage device 3 holds both the information depending on the A code and the B code.

In the storage device 3, three storage areas 31 to 33 are prepared as one set. The storage areas 31 to 33 hold information determined to be shared by the data processing devices 1 and 2 regardless of the code.

That is, in the storage area 31, the code is not a problem,
Information that may be shared is retained as it is (hereinafter referred to as first information).

In the storage area 32, the code of the first information (for example, A code)
The same information converted into an expression by a code different from (for example, B code) is held (hereinafter referred to as second information).

The storage area 33 holds a flag for indicating what the code of the first information is.

A setting unit (setting means such as a setting control program) 5 performs necessary processing for setting information in the storage areas 31 to 33.

The reference unit (reference means such as a reference control program) 6 performs necessary processing for referring to the information set in the storage areas 31 to 33.

[Action]

When the setting unit 5 determines that there is a possibility that the data processing devices 1 and 2 will share certain information, the setting unit 5 holds this as the first information in the storage area 31 as it is. This process is
It is performed regardless of the code of the information, that is, regardless of which data processing device the information is.

Next, the setting unit 5 recognizes the code of the first information, generates a flag corresponding to the code, and holds it in the storage area 33. For example, when the first information depends on the A code, the flag indicates that the first information is the information of the data processing device 1 (A
It depends on the code).

Further, when the setting unit 5 recognizes that the A code and the B code are different codes (when a plurality of codes are supported in the data processing system), the first information is set to A.
The information is converted into information that depends on a code (for example, B code) different from the code, and this is stored in the storage area 32 as the second information. When the A code and the B code are the same (only one code is supported), the setting unit 5 does not set the second information.

The reference unit 6 determines which code depends on which code needs to be shared (which data processing device to use), and refers to the flag to determine where the desired information is. To do. Specifically, it is determined whether the first information depends on the desired code (whether the information is obtained by the data processing device to be used).

For example, when the reference unit 6 recognizes that the flag indicates that the first information is previously obtained by the data processing device 1 when the information processing device 1 tries to use the information, The first information is referred to regardless of the presence or absence of the second information.

Further, for example, when it is recognized that the flag indicates that the first information of the certain information to be used in the data processing device 1 is previously obtained by the data processing device 2, the reference unit 6 Whether or not the second information exists is determined. Then, when the second information is present, the reference unit 6 determines that the second information
Assuming that the information depends on the desired code,
Refer to this. When the second information does not exist, the reference unit 6 recognizes that the second information does not exist because the A code and the B code are the same, and refers to the first information as desired information.

As described above, in a data processing system in which a plurality of codes are used or may be used, one data processing device of the system expresses a code which is not supported by the OS of the device. The information provided can be used without being aware of the code.

The setting unit 5 and the reference unit 6 are the OS 41 and / or O
Various combinations can be provided in S42 (usually provided in either one of the data processing devices), and in accordance therewith, necessary data transfer between the data processing devices 1 and 2 can be performed. it can.

In addition, when three or more codes (for example, A, B and C codes) are used, the B information corresponding to the first information depending on the A code is used.
Code-dependent second information and C-code dependent second information are prepared, and these are identified by flags.

〔Example〕

FIG. 2 is a block diagram of an embodiment of the present invention, showing a data processing system according to the present invention.

In FIG. 2, 1 and 2 are a workstation and a host computer as a data processing device, respectively.
Reference numerals 4 and 35 are storage areas, 51 and 52 are setting sections, which correspond to the setting section 5, 61 and 62 are reference sections, which correspond to the reference section 6.

The workstation 1 develops, executes, and debugs the program, and the host computer 2 integrates the programs obtained by the workstation 1 and executes or operates the integrated program. The codes supported by the OSs 41 and 42 may be the same or different from each other.

In the storage device 3, the storage area 34 is for holding the information obtained by the workstation 1 (OS 41 thereof),
The storage area 35 is for holding information obtained by (the OS 42 of) the host computer 2.

Hereinafter, a case will be described in which the setting unit 51 of the workstation 1 sets the information obtained by the workstation 1 and the reference unit 62 of the host computer 2 refers to the information to be used by the host computer 2.

In the following description, since the information to be handled is obtained by the processing in the workstation 1 (OS41 of the workstation) and operated in the host computer 2 (OS42 of the workstation), the OS41 is called a language processing system and the OS42 is called an operating system.

(A) Setting process The setting unit 51 determines that the workstation 1 and the host computer 2 may share certain information obtained by the workstation 1, that is, certain information obtained by the interface of the language processing system. Then, the following processing is performed according to the setting processing flow shown in FIG.
At the start of processing, no information is set in the storage areas 31 to 33, as shown in FIG.

The setting unit 51 uses the storage area 34 for the information, for example.
Is read from the memory and is stored in the storage area 31 as the first information. This processing is performed regardless of how the first information is obtained (which code depends on).

The setting unit 51 determines whether the first information is the information obtained by the interface of the language processing system (information for the language processing system) or the information obtained by the interface of the operation system (information for the operation system). . That is, what code the information depends on.

The setting unit 51, knowing that the first information is the information obtained by the interface of the language processing system, generates a flag to that effect and holds it in the storage area 33.

The setting unit 51 determines whether the codes of the language processing system and the operation system are the same.

When the codes are different from each other, for example, the language processing system supports ASCII code and the operating system is EBCDI
If C code is supported, the setting unit 51
The first information that depends on the CII code is converted into data that depends on the EBCDIC code, and this is held in the storage area 32 as the second information. As a result, the storage areas 31 to 33 are brought into the state shown in FIG.

On the other hand, when the codes are the same, the setting unit 51 does not set the second information. As a result, the storage areas 31 to 33 are in the state shown in FIG. 4 (B).

Even when the first information is information obtained through the interface of the operating system, processing and are performed after setting a flag indicating that, as in the case described above.

The above setting process is performed in the same manner even when the setting unit 52 performs instead of the setting unit 51.

(B) Reference Processing The reference unit 62 performs reference processing on the information held in the storage areas 31 to 33 according to the reference processing flow shown in FIG.

The reference unit 62 determines in which system the information obtained by the reference processing is used, that is, which code depends on which information is desired to be referred to.

The reference unit 62 refers to the storage area 33 and determines the flag.

While the flag indicates that the first information is the information obtained by the interface of the language processing system, the information to be referred to is the data for the operating system, so the reference unit 62 may have different codes. Therefore, the presence / absence of the second information is determined.

When the second information exists, the reference unit 62 knows that the codes are different from each other, and refers to the second information as the information that depends on the desired code.

For example, if the language processing system supports ASCII code and the operating system supports EBCDIC code, the information that depends on the EBCDIC code, which is the second information, is referenced and used in the operating system that supports this. To be done.

If the second information does not exist, the reference unit 62 knows that the systems are different but the codes are the same, and the first unit
Reference information as information that depends on the desired code.

The flag indicates that the first information is the information obtained by the interface of the language processing system, but when the information to be referred to is the same, the reference unit 62
Refers to the first information as desired information without referring to the second information. Similarly, when the information obtained through the interface of the operating system is the same, the first
Information is referenced.

The above reference processing is performed in the same manner even if the reference unit 61 performs processing instead of the reference unit 62.

Normally, the setting unit 51 and the reference unit 61 are provided on the workstation 1 side, and the setting unit 52 and the reference unit 62 on the host computer 2 side are omitted.

〔The invention's effect〕

As described above, according to the present invention, in a data processing system in which a different code may be used therein, when the code is different, the information is held in a predetermined area where information is automatically converted. Information of different codes can be used without being aware of the code.
Differences in code can be absorbed in the system, and complicated processing can be facilitated.
