Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character code converter, and more particularly to a character code converter for file transfer between computers having different character codes.

[0002]

2. Description of the Related Art In the world of computers, numbers, alphabetic characters, Chinese characters, etc., which are commonly used by us, are converted into character codes and used in the computer so that the computer can easily process them. Currently, there are several types of character codes, such as EBCDIC and JIS, and a computer adopts one of them as a processable character code. is there.

When a file is transferred between computers having different character codes, the file data is transmitted as the character code that can be processed by the sending computer. Therefore, in order to make the received file data processable on the receiving computer, it is common to examine the character code of the sending side and the character code of the receiving side and convert the character code with a code conversion tool. ..

[0004]

The code conversion tool that has been used in the past requires confirmation of the character codes that can be processed by the sending side and the receiving side before starting up. Since an incorrect character code may be specified due to a parameter input error, the following processing may be performed without the code conversion being performed correctly.

Further, regarding code conversion of a computer without a code conversion tool, enormous man-hours are required because a character code conversion correspondence table is created and converted manually, or an original program is created and converted. There was a problem.

[0006]

The automatic character code conversion apparatus of the present invention performs character code conversion by means of character code registration means for registering the character code used by the computer that is the transfer source or transfer destination of the file. Character code conversion table registration means for registering conversion data for performing, computer information input means for specifying a computer of a file transfer source and a transfer destination computer for receiving the file, and a computer specified by the computer information input means A character code identifying means for identifying a character code to be processed, and a corresponding character code conversion data is searched by the character code identified by the character code identifying means, and the data in the data file is converted into a transmission file and output. And a character code conversion means.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. The present invention is activated by a computer on the transmission side, and includes character code registration means 102, character code master 103, character code conversion table registration means 1
04, character code conversion table 105, computer information input means 106, character code identification means 107, and character code conversion means 108. In using the automatic character code conversion device of the present invention, first, basic data is registered. As basic data,
Character code registration means 1 for character code information of a computer
A computer identification code and processable character code information are input from the keyboard with 02 and registered in the character code master 103. Further, the character code conversion information is input by the character code conversion table registration means 104 using the keyboard, and the character code information before conversion and the character code data, and the character code information after conversion and the character code data are input by the character code conversion table registration means 104. Both have functions of registration, update, and deletion.

When all the basic data are registered, the computer information input means 106 inputs the computer identification codes of the transmitting side and the receiving side from the keyboard. The input computer identification code is the character code identification means 1
In 07, it becomes a key for referring to the character code master 103, and the information of the character code used in the sending and receiving computers can be obtained. This character code information serves as a key for searching the character code conversion table in the character code conversion means 108, and character code conversion data can be obtained. Character code conversion means 108
Then, input the data of the data file 109, perform the code conversion with the contents of the retrieved character code conversion data,
Output to the transmission file 110.

Next, the process of converting the character code will be described in more detail with reference to FIGS.

FIG. 2 is a flow chart showing the flow of the character code conversion process.

First, in step 201, the computer code of the transmitting side and the computer code of the receiving side are input. At this time, check whether the entered computer code exists in the character code master,
If there is an error, enter it again. Next, in step 202, the character types of the transmitting side and the receiving side are displayed on the screen, respectively, and confirmation is input. If the confirmation is negative, that is, N, the process returns to step 201, and if the confirmation is positive, that is, Y, code conversion is performed (step 203).

In step 203, a message indicating that the code is being converted is displayed on the screen, and if the conversion is completed and it is necessary to continue the processing, the confirmation input of the processing continuation is input (step 204). If the confirmation is positive, that is, Y, step 2
Returning to 01, if the confirmation is negative, that is, N, file transfer processing is performed.

FIG. 3 shows a data flow in the character code conversion process.

The character code identifying means 1 is respectively obtained from the computer identification codes of the transmitting side and the receiving side which are inputted from the screen.
The character code identification processing unit 301 in 07 searches for a character code identification code. Then, from the character code identification code, the character code conversion processing unit 3 in the character code conversion means 108.
In 02, which conversion table to use is positioned. Next, the pre-conversion data 303 in the data file 109
Is read character by character from the character conversion table on the transmission side positioned by the character code conversion processing unit 302, and the number of the character code read in the table is searched. Then, the character code at the same position in the character conversion table on the receiving side is searched, and the converted data 304 in the transmission file 10 is written. The process of writing the post-conversion data 304 corresponding to the reading from the pre-conversion data 303 is repeated until the data of the pre-conversion data 303 is completed.

[0016]

As described above, according to the present invention, the information of the character code that can be processed by the computer is registered in the master so that the information can be easily fetched by the computer identification code. The user does not need to be aware of the character code that can be processed on the sending side and receiving side, and can save the trouble of checking. Further, there is an effect that a mistake in confirming the character code and a mistake in inputting a parameter when using the code conversion tool are significantly reduced.

Further, the conversion information of all character codes is registered as a table, and when the character code to be converted is identified, the character code conversion table is automatically searched and the code conversion is performed by the conversion data. Even on a computer in which a code conversion tool cannot be used, there is no need to create a program or manually perform code conversion, and the number of work steps can be significantly reduced.
