[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 a data processing system, information such as one-character data is expressed by, for example, a code associated with each character. There are several types of this code with different expression formats, such as ASCII code and EBCDIC code, which are two-character data codes.

[Prior Art] Information expressed by a certain code has no meaning as it is in a data processing device that employs another code.

However, in reality, while nine different codes are used, data and programs, ie, information, are often shared among a plurality of data processing devices.

Therefore, information expressed using one code is converted into information expressed using another code.

This conversion process is performed by, for example, a code converter (means).

[Problem that the invention seeks to solve]

In the prior art described above, in order to perform conversion processing, a programmer/operator or the like needs to give an instruction to that effect. In addition, for this purpose, it is necessary to be aware of the code used to express the information, and to be aware of the code adopted by the data processing device that is going to use that information.

Furthermore, since such care is required, processing tends to become complicated.

In this way, conventionally, in a data processing system where multiple codes may be used internally, when using certain information, it is necessary to perform processing that is conscious of the code, and that processing is This was a heavy burden on programmers/operators.

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

[Means for solving problems]

FIG. 1 is a diagram showing the principle structure of the present invention, and shows 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 data processing devices 1 and 2;
1 to 33 are memories su for holding predetermined information.
ME, 41 and 42 are operating systems (
5 is a setting unit that sets information to be held in the storage areas 31 to 33; 6 is a reference unit that refers to information held in the storage areas 31 to 34;

The O541 of the data processing device 1 employs (supports) one code (A code) as a code for expressing information. Therefore, information created, developed, or used in the data processing device 1 is expressed using the A code (hereinafter referred to as information dependent on the A code).

The OS 42 of the data processing device 2 employs (supports) a code (B code) that is different from the A code. Therefore, the information for the data processing device 2 is:

This information depends on the B code.

The storage device 3 holds both A code and B code dependent information.

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

In other words, the storage area 31 retains information that may be shared as is, without worrying about the code.
(hereinafter referred to as 1st information).

The storage area 32 stores the same information that has been converted into a representation using a code (e.g. B code) different from the first information code (e.g. A code) (hereinafter referred to as second information).
.

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

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

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

[For production]

When the setting unit 5 determines that there is a possibility that the data processing apparatuses 1 and 2 may share certain information.

This is held as it is in the storage area 31 as first information. This process is performed regardless of the code of the information, i.e.
This is done regardless of which data processing device the information is from.

Next, the setting unit 5 recognizes the code of the first information.

A flag corresponding to this is generated and held in the storage area 33. For example, when the first information depends on the A code,
The flag indicates that the first information is information about the data processing device 1 (depends on the A code).

Further, when the setting unit 5 recognizes that the A code and the B code are different codes (when multiple codes are supported in the data processing system), the setting unit 5 converts the first information into a code different from the A code ( For example, the B code) is converted into information dependent on the B code, and this is held in the storage area 32 as second information. Also.

When the A code and the B code are the same (when only one code is supported), the setting unit 5 does not set the second information.

The reference unit 6 determines which code depends on information that may be shared (which data processing device it should be used with), and determines where the desired information is located by referring to the flag. do.

Specifically, it is determined whether the first information depends on the desired code (is the information obtained by the data processing device to be used).

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

For example, if the data processing device 1 recognizes that the flag indicates that the first information was obtained first in the data processing device 2, the reference unit 6 It is determined whether or not the second information exists. Then, when the second information exists, the reference unit 6
Assuming that the information is information dependent on the desired code,
Refer to this. Further, when the second information does not exist, the reference unit 6 detects that the A code and the B code are the same, so the
Recognizing that the information does not exist, the first information is referred to as the desired information.

As a result of the above, in a data processing system in which multiple codes are used or may be used, from one data processing unit of the system to a code that is not supported by the O3 of that unit. Also regarding the information given.

You can use it without knowing the code.

In addition, the setting section 5 and the reference section 6 are O341 and /
or can be provided in various combinations in the OS 42 (usually provided in one of the data processing devices) so that the necessary data transfer is performed between the data processing devices 1 and 2 accordingly. be able to.

Also, 3 or more chords (e.g. A, B and C chords)
is used, second information that depends on the B code and second information that depends on the C code are prepared corresponding to the first information that depends on the A code.

These are identified by flags.

〔Example〕

FIG. 2 is a block diagram of one 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 data processing devices, respectively, 34 and 35 are storage areas, and 51 and 52 are setting units, which correspond to the setting unit 5.

61 and 62 are reference parts, which correspond to the reference part 6.

Workstation 1 develops, executes, and depacks programs, and host computer 2 integrates the programs obtained at workstation 1.

Execute or operate the integrated program.

The codes that 0341 and 42 support are similar to each other.

They may be the same or different.

In the storage device 3, the storage area 34 is for holding information obtained from the workstation 1 (O341), and the storage area 35 is for holding information obtained from the workstation 2 (O341).
This is to hold the information obtained in step S42).

Hereinafter, the setting unit 51 of the workstation 1 sets the information obtained by the workstation 1.

A case where the reference unit 62 of the host computer 2 refers to it and uses it in the host computer 2 will be described.

In the following explanation, since the information to be handled is obtained through processing in the workstation 1 (O541) and operated on the host computer 2 (O342), O541 will be referred to as the language processing system, and OS 42 will be referred to as the operating system. That's what it means.

(a) The setting processing setting unit 51 receives certain information obtained from the workstation l,
That is, when it is determined that there is a possibility that the workstation 1 and the host computer 2 will share certain information obtained through the interface of the language processing system,
At the start of the process, in which the following process is performed according to the setting process flow shown in FIG.
As shown in FIG. 4(^), no information is set.

(2) The setting unit 51 reads out one piece of the information from, for example, the storage area 34 and holds it in the storage area 31 as first information. This process is performed 9 regardless of how the first information was obtained (depending on which code).

■ The setting unit 51 determines whether the first information is information obtained through the interface of the language processing system (information for the language processing system) or information obtained through the interface of the operating system (information for the operating system). do. That is, check what code the information depends on.

(2) When the setting unit 51 learns that the first information is information obtained through the interface of the language processing system, it generates a flag indicating this and stores it in the storage area 33.

(2) The setting unit 51 determines whether the codes of the language processing system and the operating system are the same.

■ Case where the codes are different 1 For example, if the language processing system supports the ASCII code and the operating system supports the HBCDIC code, the setting unit 51 converts the first information that depends on the ASCII code into the EBCDIC code. Convert to dependent data.

This is held in the storage area 32 as second information. As a result, the storage areas 31 to 33 are in the state shown in FIG. 4(C).

On the other hand, if the codes are the same, the setting unit 51
This is the result of not setting the second information.

The storage areas 31 to 33 are in the state shown in FIG. 4(B).

(2) Note that even if the first information is information obtained through the interface of the operating system, a flag indicating that fact is set, as in the case described above.

Processes (1) and (2) are performed.

The above setting process can be performed in the same way even if the setting unit 52 is used 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.

(2) The reference unit 62 determines in which system the information obtained through the reference processing is to be used, that is, which code-dependent information is desired to be referenced.

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

■ While the flag indicates that the first information is information obtained through the interface of the language processing system, the information to be referenced is data for the operating system, so the reference unit 62 indicates that the codes may differ from each other. Therefore, the presence or absence of the second information is determined.

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

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

(2) If the second information does not exist, the reference unit 62 knows that the codes are the same although the systems are different, and refers to the first information as information that depends on the desired code.

■ The flag indicates that the first information is information obtained from the interface of the language processing system, and if the information you want to refer to matches this, the reference section 6
2 refers to the first information as desired information without referring to the second information. Furthermore, when the information obtained from the interface of the operating system matches, the first information is similarly referred to.

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

Note that normally, the setting section 51 and the reference section 61 are provided on the workstation I side, and the setting section 52 and the reference section 62 on the host computer 2 side are omitted.

〔Effect of the invention〕

As explained above, according to the present invention, in a data processing system that may use different codes internally, when the codes are different, information is automatically stored in a predetermined area where information is converted. This allows you to use information from different codes without being aware of the code.
Differences in code can be absorbed into the system, making complex processing easier.
