Abstract

PURPOSE:To prevent failure such as the display distortion of a character display device since character codes are not matched to an operating system(OS) by providing an OS use character code list, character code collation table mutually for between character codes and character code conversion part depending on the character code collation table. CONSTITUTION:Character data inputted by a user are converted and transferred, the file name of a file 11 storing the character data and the name of the OS at a transfer destination are read. While referring to a use character code list 13, the use character code of the transfer destination is recognized as an 8 bit JIS code. Next, one unit of the character data in the file 11 is read to the end of the character data, and while referring to the character code collation table 14, the correspondent character data are read and stored in a file 16. When the character data are finished, the operation is branched to a data transfer processing, and the data are transferred after recognizing the form of connecting the OS each other.

Description

[Detailed description of the invention]

0001

[Industrial Field of Application] The present invention relates to a character data conversion and transfer method, and particularly to a method for converting and transferring character data, and in particular,
This invention relates to a character data conversion and transfer method for converting and transferring character data between computers operating on the computer.

0002

[Prior Art] As an example of this type of character data conversion and transfer method, shift JIS code, which is a Japanese character code, is transferred from a personal computer running MS-DOS developed by Microsoft, which is widely used as an OS for personal computers, etc. An example of this is similarly transferring character data from a personal computer to a workstation running the UNIX OS developed by ATT, such as a host computer. In this case, it is necessary to convert character data based on shift JIS code into character data based on 8-bit JIS, which is one of the Japanese character codes of UNIX.

As shown in FIG. 3, the conventional character data conversion and transfer method converts the transferred character data at the transfer destination.
It was converted into character data based on the character code of the destination OS.

In FIG. 3, the conventional character data conversion and transfer method uses MS-DOS as the OS and transfers the Shift JI
A personal computer 3 that includes a file 11 of character data based on S code and a transmitting section 12 that transfers the file, and a receiving section 21 that uses UNIX as an OS and receives the transferred data.
and a file 22 for storing received character data, a character code converter 23 for converting character data based on the shift JIS code of the received character data into character data based on 8-bit JIS, and a file 24 for storing the converted character data. It consisted of 4 workstations.

Next, the operation of the conventional character data conversion and transfer system will be explained.

FIG. 4 is a flowchart showing the operation of the conventional character data conversion and transfer method shown in FIG.

In FIG. 4, first, the personal computer 3 of the transfer source reads the file name of the character data file 11 in which the character data to be transferred is stored and the OS (UNIX) name of the transfer destination (step P1). ).

Next, the contents of the file 11 are transferred to the workstation 4 via the transmitter 11 (step P2
).

The workstation 4 stores the character data transferred via the receiving section 21 in the file 22 (step P3).

Next, the shift J stored in the file 22
Character data based on the IS code is read out, converted into character data based on 8-bit JIS by the character code converter 23, and stored in the file 24 (step P4).

[0011]

[Problems to be Solved by the Invention] The conventional character data conversion and transfer method described above transfers character data in the character code of the transfer source OS, and converts the character data at the transfer destination into the character code of the transfer destination OS. However, if the character code of the source OS is processed at the destination due to an error such as forgetting to convert the character data, the character code may be incompatible with the OS and the display of the character display device may be distorted. It has the disadvantage of causing problems. Furthermore, since a system is constructed individually each time transfer between specific OSes is required, it has the disadvantage of lack of versatility.

0012

[Means for Solving the Problems] The character data conversion and transfer method of the present invention operates on a second operating system by converting first character data encoded with a first character code in a first operating system. In the character data conversion and transfer method of converting and transmitting second character data encoded with a second character code in the second operating system of the processing device, each of the first and second operating systems a list of character codes used by operating systems in which a comparison between the name and the first and second character codes corresponding to the first and second operating systems, respectively, is described, and the first character; a character code comparison table in which the second character code corresponding to the code is described; and a character code conversion unit that converts the first character code into the second character code using the character code comparison table. It is composed of

[0024] Next, refer to the character code list 13 and read the character code used by the destination OS into the 8-bit J
It is recognized that it is an IS code (step S2).

Next, it is checked whether the character data in the file 11 has ended (step S3). If no, proceed to step S4 and shift J of file 11.
Read one unit of character data of the IS code.

Next, referring to the character code comparison table 14, the character data of the 8-bit JIS code corresponding to the character data of the shift JIS code read in step S4 is read (step S5).

Next, the read character data of the 8-bit JIS code is temporarily stored in the file 16 (step S6).
).

The above processing of steps S3 to S6 is continued until the end of the character data in the file 11.

Next, if the result in step S3 is YES, that is, the character data of file 11 is the end, the process branches to data transfer processing, and mutual O
The connection form between S is recognized (step S7).

Finally, the data temporarily stored in the file 16 is transferred to the destination workstation 2 via the transmitter 12.
