Description

[Detailed Description of the Invention] [Required] The object of the present invention is to provide a character data processing device that facilitates the processing of character data in which character codes of a plurality of code systems coexist in a computer. It has an output means, the input means generates character string data from given input data, and the character string data is
It is composed of a character code string and a code flag string, the character code string is a sequence of character codes of a plurality of different predetermined code systems, and the code flag string is a sequence of code flags, and each code flag indicates the code system of the corresponding character code for each predetermined number of character codes of the character code string, and the output means outputs the code flag of the code flag string and the character code string of the character code string. Based on the correspondence with the character code, a required control code is inserted into each consecutive sequence of character codes of the same code system in the character code string to generate output data.

[Industrial application field]

The present invention relates to character data processing in a computer, and particularly to a character data processing apparatus for character data in which character codes of a plurality of code systems coexist.

[Prior art and problems to be solved by the invention] Figure 2 is an example of character data including Japanese characters, and Figure 2 (a)
As shown in Figure 2(b), the character data when half-width alphanumeric characters and full-width Japanese characters are mixed is the code of the half-width character expressed in 1 byte and the code expressed in 2 bytes, as shown in Figure 2 (b). The code of the double-byte character represented and the control code that indicates the switching (shift) of the code type (“28” in the figure, r29
”).

All character data is structured as data in this format, so a control code is inserted during data generation for each business processing program that generates and processes such data. Processing must be carried out while being aware that it is inserted inside.

This process is done by inserting the control code as described above.
Since there is a digit shift between the character digit position and the character code position on the data, the correspondence between the two becomes complicated, which complicates the character data resetting process.

Furthermore, there are multiple types of variations in the control code group, and if necessary, a program corresponding to each type is required.

An object of the present invention is to provide a character data processing device that easily and efficiently processes character data in which character codes of a plurality of code systems coexist.

[Means to solve the problem]

FIG. 1 is a block diagram showing the configuration of the present invention.

The figure shows the configuration of a character data processing device, which has an input means 1 and an output means 2. The input means 1 receives given input data 3.
generates character string data 4 from The code flag string 6 is a sequence of code flags, and each code flag indicates the code system of the corresponding character code for each predetermined number of character codes of the character code string. Based on the correspondence between the code flag in the code flag string 6 and the character code in the character code string 5, the output means 2 outputs each consecutive sequence of character codes of the same code system in the character code string 5. A required control code is inserted into the output data 7 to generate output data 7.

[For production]

With this processing device, character string data 4 is created by input means 1 using input information or existing output data as input data 3, and character string data 4 is divided into two parts: a character code string 5 and a code flag string 6. This configuration eliminates the need for inserting code sequences representing characters and control codes, thereby eliminating the processing complexity described above. In addition, various business processes use this character string data 4 as a processing target, and when it is necessary to output a form, etc., the output means 2 creates the character string data 4 and output data 7 in a conventional format in which a control code is inserted. By doing so, parts that require individual handling for each type of control code group can be integrated into only the output means.

〔Example〕

FIGS. 2(C) and 2(d) are diagrams illustrating an example of the structure of the first character string data 4. The input means 1 inputs only the character code for each character of the input data as shown in (C). The code flags indicating the code system of each character code (for example, full-width is J and half-width is E) are set as 1-byte information, and in the same order as the character codes (d).
They are arranged as code flag string 6.

Here, as shown by connecting (C) and (d) in FIG. 2 with a broken line, each code flag J corresponds to a 2-byte character code, and the code flag E corresponds to the character code 2 of consecutive
correspond to pairs of individuals.

This example is an example of character string data corresponding to the character string in FIG. The digit position matches each character of the character string in a).

For example, the output means 2 in FIG. 1 scans the code flag string in (d) for the character string data consisting of (C) and (d) in FIG. When a code is output and the code flag in the code flag string changes, a predetermined control code (in the example shown in the figure, control code "29" for J-+E) is inserted between the corresponding character codes before and after the change. , in the case of E→J, control wholesale code r28J
) is output. By processing in this manner, data as shown in FIG. 2(b) is output from the character string data of FIG. 2(C) and (d).

FIG. 3 is a diagram showing an example of the processing flow of the output means,
First, in processing step 10, initial control information such as storing the beginning of a code flag string of character string data is set, and processing is started.

In processing step 11, one code flag string is taken out one by one from the beginning and compared with the stored code flag (hereinafter referred to as the previous code flag).If they match, in processing step 12 the corresponding character code 2 of the character code string is extracted. The byte is output, identified in process step 13, and returns to process step 11 if there is a subsequent code flag.

If it does not match the previous code flag in processing step 11, the type of code flag is identified in processing step 14, and if rJ, then control code "28" is output in processing step 15, and if rB, then in processing step 16, the control code "28" is output. Control wholesale code
29" is output.

Next, in processing step 17, after updating the previous code flag to the code flag just checked, processing step 12
Outputs the 2-byte character code corresponding to the code flag.

Note that the output means 2 receives the control code type designation, and
It may be configured to be compatible with various restricted i1H codes.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, in processing character data of a computer, character data in which character codes of multiple code systems coexist can be easily and efficiently processed, which is a remarkable industrial effect. There is.
