DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic identification system of a source unit coding system, and more particularly, to a source unit whose coding system is unknown at the time of receiving a file transfer, automatically converting the coding system usable in the own system. It relates to the conversion method.

[0002]

2. Description of the Related Art In a conventional file transfer system, there are various types of file transfer means and code system conversion means. A means for automatically identifying a unit code transferred from another system to its own system is provided. Since it is not provided, it is necessary to know what the code system of the source unit (source program) transferred from another system is.

In this case, if the operator knows the code system of the source unit transferred from another system, it can be used in the own system using various code conversion means provided in the own system. It can be converted to a simple coding system. That is, in order to perform the conversion of the code system, it is necessary for the operator to grasp the code before the conversion and the code after the conversion, and to use a correct code conversion means. If it is unknown, it is necessary to clarify the code system of the unknown source unit by some method such as a file dump before executing the code conversion means.

As a prior art of a character code automatic conversion apparatus, for example, Japanese Patent Laid-Open Publication No. Hei 5-341956 discloses that in file transfer between computers having different character codes, a user is conscious of the character codes of the transmitting and receiving computers. A device that automatically and accurately converts character codes without inputting the identification codes of the transmitting and receiving computers from a keyboard to obtain information on the character codes used by the transmitting and receiving computers. In this way, a device for performing character code conversion has been proposed.

[0005]

As described above, in the conventional file transfer of a source unit, an operator grasps a code system before conversion and a code system after conversion, and manually selects an appropriate code conversion means. Judgment must be made, and this work is complicated, and the number of work steps becomes enormous with the increase in the number of source units to be transferred, and an artificial error may occur.

[0006] The reason for the above problem is that means for automatically identifying a code system at the time of receiving a source unit is not implemented in the prior art.

In the automatic character code conversion apparatus described in Japanese Patent Application Laid-Open No. 5-341956, the user is required to perform a manual operation such as inputting an identification code of a computer. Does not disclose any technique for automatically identifying a code system.

When developing application software, a program creator (programmer) creates a source unit (program). However, it is difficult to provide the same development machine environment (computer environment) to all programmers from the viewpoint of cost.

For this reason, each programmer usually develops a program in various different machine environments. In this case, for example, the character code of the source program is also different due to the difference of the machine environment. Therefore, when the program is jointly developed, not only the integrity management of the version of the source unit but also the source unit is required. It is necessary to ensure the consistency of the character code when the file is transferred between computers by file transfer or the like. in this case,
If a computer is equipped with a system that identifies the code system of a source unit that is automatically transferred, regardless of the number of hands, it will surely contribute to improving the operability and development efficiency of programmers engaged in program development. .

Accordingly, the present invention has been made in view of the above circumstances, and has as its object to cooperate with a co-developer who uses another environment without an operator being conscious of the code system of the source unit. It is an object of the present invention to provide an automatic identification system of a code system at the time of file transfer of a source unit, which enables transmission and reception of a source unit between the source units.

[0011]

In order to achieve the above object, an automatic identification system of a code system at the time of file transfer of a source unit according to the present invention is provided by using a program language for a source unit file transferred from another system. Means for automatically identifying a code system, means for automatically identifying a code system, a table in which predetermined keywords for each programming language are stored in advance for each code system for performing identification, and means for converting the code system into a code system usable in the own system. And characterized in that:

The outline of the present invention will be described below. In the present invention, the automatic identification means of the programming language and the automatic identification means of the code system are arranged such that a keyword of each program for each code system for performing identification with respect to a source unit given from another system by a file transfer. By searching a table stored in advance and checking whether a keyword is present in the source unit, the language and code system of the source unit transferred to the own system as a file are simultaneously determined. Have been.

[0013] The keyword table of each program for each code system for identification stores the keywords of various program languages, preferably the most characteristic, which are unique to the program language, for each code system.

The means for converting to a code system that can be used in the own system converts the source unit of the code system determined by the code system identification means into a code system that can be used in the own system (operable by the operator). Do. Normally, the conversion means of this code system must specify the code before conversion and the code after conversion, but by limiting the source unit after conversion to use in the own system, the converted code is fixed. The value can be used, and operability can be improved.

[0015]

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

FIG. 1 is a diagram showing a configuration of an embodiment of the present invention. Referring to FIG. 1, an automatic identification system of a code system at the time of file transfer of a source unit includes a file transfer unit 101 and various code conversion units 104 for each received code for converting into a code system usable in the own system.
(Code conversion means 1, 2, 3,...), And refers to the language key table 103 for each code system and automatically converts the code system and program language of the source unit received by the file transfer means 101. System identification means 102-1 and program language identification means 1
02-2.

Language key table 103 for each code system
Is, for example, configured as shown by 103 in FIG.
For each code system, each programming language (COBOL,
C, FORTRAN, PL / I, etc.). The keywords are words or sentences that are most characteristic in each programming language.

The functions of the code system identification means 102-1 and the program language identification means 102-2 are as follows. For the source unit whose code system received from the file transfer means 101 is unknown, it is stored in the language key table 103. Then, a comparison is made with the language keyword for each code system, the code system including the matched keyword is determined as the code system of the source unit to which the file has been transferred, and the code conversion unit 104 corresponding to the code system is activated.

The processing flow of the embodiment of the present invention will be described below. FIG. 2 is a flowchart for explaining the operation of the embodiment of the present invention.

The source unit received by the file transfer unit 101 is passed to a keyword search unit in the code system identification unit 102-1 and the program language identification unit 102-2, and a language for each code system is set in the keyword search unit. A source unit is searched based on keywords in various languages stored in the key table 103 (step 201).

The keyword search is continued until the program language keywords for each code system match. If the keywords do not match, the process returns to the keyword search again, and the next language keyword search is performed. Then, the search is continued with the next language keyword (steps 201 to 202).

If the keyword of the language key table for each code system exists in the source unit and a match is confirmed, the code system and the language are passed to the identification unit of the next received code system (step 203). .

The identification unit of the received code system activates the correct code conversion unit 104 in order to change the source unit received from the file transfer unit 101 to a code system that can be used in its own system, based on the received code system (step). 204).

The source unit converted by the code conversion unit 104 has a code system that can be used in its own system, and can be immediately edited by an editor, compiled, and the like. Note that the source unit converted by the code conversion unit 104 also has the type of the program language known by the program language identification unit 102-2, so that a compiler suitable for the program language can be automatically started. .

An embodiment of the present invention will be described below. The configuration of the example of the present invention is the same as that of the above-described embodiment of the present invention, and has the configuration shown in FIG. In the present embodiment, the internal structure of the language key table 103 for each code system is configured as shown in 103 in FIG. 2, and a keyword for each language is stored for each code system. Words and sentences. For example, COBOL
In the case of "IDENTIFICATION DIVIS
In the case of C language such as “ION”, “#INCLUDE <x
xx. h>, main () "and the like as keywords, and all languages used are prepared as a table;
These keywords are stored as codes for all code systems (JIS code, ASCII code, EDCDIC code, etc.).

The coding system identification means 102 shown in FIG.
1 and the program language identification unit 102-2 compares the source unit of unknown code system received from the file transfer unit 101 with the language keywords for each code system written in the language key table, and finds a match. The code system including the keyword is determined as the code system of the source unit to which the file has been transferred, and the correct code conversion unit is activated from among the plurality of code conversion units 104.

For example, if the conversion is from the code system 1 to the own system code system, the code conversion procedure (means) 1 is started. If the conversion is from the code system 2 to the own system code system, the code conversion procedure 2 is executed. Start up.

Next, another embodiment of the present invention will be described with reference to FIG. FIG. 3 is a flowchart for explaining a processing flow according to another embodiment of the present invention. In the flowchart of FIG. 3, the processing up to step 205 is the same as the processing up to step 205 in FIG.

One of the features of another embodiment of the present invention is that while identifying the coding system of the source unit,
It is also possible to identify what programming language the source unit is described in.
That is, in another embodiment of the present invention, in step 206 of FIG. 3, not only the conversion into the code system usable in the own system, but also the activation of the compiler applicable to the source unit immediately after the conversion, In addition, an editor or the like for editing the contents of the source unit is automatically started to further improve operability.

In step 206, not only a compiler and an editor but also other external tools can be started freely.
