2. Description of the Related Art FIG. 9 shows, for example, JP-A-63-25454.
FIG. 2 is a block configuration diagram of a conventional mixed field control system shown in Japanese Patent Publication No. 2 publication, in which 1 is a data format conversion unit, 2 is an original data file, 3 is original data input means, 5
1 is a data content discriminating means, 52 is a bitmap creating means, 5 is an intermediate file output means, 6 is an intermediate file, 7
Is a data edit processing unit, 8 is an intermediate file input means, 53
Is a bitmap analysis unit, 54 is a data expansion unit, 9 is a data editing unit, 10 is an output unit, and 11 is an output device.

Next, the operation will be described. The original data file 2 stores a record group in which 1-byte character data and 2-byte character data are mixed in one field. At this time, the 2-byte character data is stored in a format in which shift-in and shift-out which are shift codes are added to the data itself.

First, the original data input means 3 inputs a record from the original data file 2. The data content discriminating means 51 examines the data content of each read record in field units, and discriminates the existence of 2-byte code data. From the result, the bit map creating means 52 sets the bit on the bit map corresponding to the position of the 2-byte character code.

FIG. 10 is a relational diagram relatively showing the position of 2-byte character data in the field when the bit map is 1 bit. In the mixed data example 55 in the field in FIG. 10, 1-byte character data “A”, “B”, “C”, “D” and 2-byte character data “Japan” are included. This is an example of mixed one field. On the other hand, a bitmap example 56
Then, 1 bit is relatively associated with 1 byte of the mixed field, and the bit corresponding to the character position of the 2-byte character data “Japan” in the mixed data example 55 is “1”. (ON state).

Next, the bitmap created by the bitmap creating means 52 is composed of 1-byte character data and 2
It is added immediately after the field containing the byte character data and stored in the intermediate file 6 by the intermediate file output means 5. At this time, the data attribute is converted to a symbol (“M” in this example) that means mixed data.

FIG. 11 is an explanatory diagram showing an actual example of a record in the internal representation format in which the bitmap is added and the data attribute definition is converted. In FIG. 11, the internal representation format record example 57 is an example in which the mixed data example shown in FIG. 10 is converted into data including the record “M” of the data attribute 58 and the record to which the bitmap 59 is added. is there.

As described above, 1-byte character data and 2
The data format conversion unit 1 converts the original data in which byte character data is mixed into an internal representation format and stores it in the intermediate file 6.

Next, the data edit processing section 7 as means for displaying or printing the internal representation format record stored in the intermediate file 6 on the output device will be explained.
In the data edit processing unit 7, the intermediate file 6 is input by the intermediate file input means 8, the bitmap is analyzed by the bitmap analysis means 53, and the position of the 2-byte character data is obtained. The data expansion unit 54 decomposes the field data based on the position of the 2-byte character data obtained by the bitmap analysis unit 53, and adds shift codes before and after the 2-byte character data.

As described above, when the shift code is added to all the 2-byte code data, the data editing means 9 edits the record in a displayable format, and the output means 10 displays it on the output device 11. Or print.

[0011]

Since the conventional method is constructed as described above, an extra process for analyzing the bitmap is required, and the conventional data editing process cannot be used as it is. In addition, it is difficult to handle such mixed data when editing the data. However, since the shift code is added to the 2-byte character data at the stage when the data reaches the data editing means, here The problem of is not solved.

The above problems will be described with reference to the drawings. FIG. 8 is an explanatory diagram showing a process of equally dividing a field in which 1-byte character data and 2-byte character data are mixed into two.
In the figure, 45 is an example of a field in which a 1-byte character code and a 2-byte character code are mixed. In this example, shift-in and shift-out are 2
It was a bite. Reference numeral 46 is a field for storing the first half of the bisected data. 47 is a field for storing the latter half of the data obtained by dividing the data into two equal parts.

This is a process of dividing the content of the mixed field 45 into two equal parts and storing them in the first half partial field 46 and the second half partial field 47, respectively. The problem at this time is
This means that the boundary when dividing into two parts may overlap the 2-byte character data. The boundary at which the mixed field 45 is divided into two halves is "Kan" which is a 2-byte character code. If you divide the data here, the "Kan" data will be destroyed. Here, it is avoided by allocating "han" to the first half.

Depending on whether the boundary when dividing into two is 1-byte character data or 2-byte character data,
End of first half partial field 46 and second half partial field 4
The processing at the start of 7 changes. In FIG. 8, the equally divided boundary is 2-byte character data, and since it ends with a 2-byte character code, shift-out and shift-in are performed at the end of the first half field 46 and the start of the second half field 47, respectively. Is added. If the boundary is 1-byte character data, it is not necessary to add a shift code. In order to determine the character code on the boundary, it is necessary to analyze the character data from the beginning of the mixed field 45, which causes great difficulty in creating the program.

The present invention has been made to solve the above problems, and is data conversion that facilitates editing of a field in which 1-byte character data and 2-byte character data are mixed. The purpose is to provide a processing method.

[0016]

A data conversion processing system according to the present invention is a data processing apparatus for processing data in which a 1-byte character code and a 2-byte character code are mixed in one field. Based on the 1-byte character code, a table that can refer to the 2-byte character code corresponding to the character is provided, and the 1-byte character code is converted to the 2-byte character code using this table. A conversion means is provided so that when a 1-byte character code and a 2-byte character code are mixed in one field, the 1-byte character is replaced with the corresponding 2-byte character. is there.

Furthermore, in the data conversion processing method according to the present invention, when a 1-byte kana character code is followed by a dakuten or semi-dakuten code, a 2-byte character code corresponding to the 1-byte kana character is added. A predetermined constant is added to replace a 1-byte type kana character and the subsequent dakuten and semi-voiced point with a corresponding 2-byte type dakuon or semi-voiced sound character.

[0018]

According to the present invention, the table for converting the 1-byte character code to the corresponding 2-byte character code is provided, and the 1-byte character is converted into the 2-byte character. As a result, 1-byte character data and 2
2 for the contents of the field in which byte character data is mixed
It can be unified into byte character codes.

When a kana character of 1-byte character is followed by a dakuten character and a semi-voiced character, a constant is added to the corresponding 2-byte character code to convert it into a 2-byte character character of dakuon or semi-voiced sound. In this way, by converting 1-byte kana character data with dakuten and semi-dakuten into a 2-byte character code with dakuten and semi-voiced, the data length that can be stored in the field can be made as long as possible. ..

【Example】

Example 1. FIG. 1 is a block diagram of a data conversion processing system showing an embodiment of the present invention. In the figure, 1 is a data format conversion unit for converting the format of data, and 2 is a conventional 1
Original data file in which a record group consisting of fields in which byte character codes and 2-byte character codes are mixed is stored, 3 is an original data input means for inputting records of the original data file 2, 4 is an input 1 byte Data conversion means for converting a field in which a system character code and a 2-byte character code are mixed, 5 is an intermediate file output means for outputting the converted data to an intermediate file, and 6 is an intermediate file in which a record group after conversion is stored , 7 is a data edit processing unit for outputting data to an output device, 8 is an intermediate file input means for inputting a record of the intermediate file 6, 9 is data editing means for editing a field in the input record, and 10 is an edited Output means for outputting data to the output device, 11 is for actually displaying the contents of the field,
An output device for printing.

Next, the operation will be described. First, the data format conversion unit 1 that converts the format of data will be described. The record of the original data file 2 is input by the original data input means 3. The input record is the data conversion means 4
Check the contents of data in units of fields and check if there is 1-byte character data. If a 1-byte character code exists, it is converted to a 2-byte character code corresponding to the character. At the same time, the shift codes existing before and after the 1-byte character code can be removed. When the data conversion means 4 completes the data conversion for one record in this way, the intermediate data output means 5
Is output to the intermediate file 6. The intermediate file 6 is created by repeating this series of processes for the number of records of the original data file 2.

Here, the operation of the data conversion means 4 will be described in detail with reference to the flowchart of FIG. In the figure, 12
To 30 correspond to the processing steps described in the text.

Further, FIG. 3 shows the data used in the data conversion means 4, and in the figure, 31 is a buffer on the memory in which the record input by the original data input means 3 is stored, which is designated as buffer A here. Reference numeral 32 is a buffer on the memory in which the record converted by the data conversion means 4 is stored, and is referred to as buffer B here. An address value 33 can be set by the pointer of the buffer A31. This pointer can refer to / update the contents of an arbitrary place of the buffer A, and this pointer is referred to as a pointer A. Reference numeral 34 is a pointer of the buffer B 32, which is a pointer B here.

Further, in FIG. 4, the 1-byte character code is 2
It is a data conversion table for converting into a byte character code. The data conversion table 35 has 25 2-byte elements.
In each of the six tables, a 2-byte character code corresponding to a 1-byte character code is stored in each element, and the order is the order of the value of the 1-byte character code. To refer to a 2-byte character corresponding to a 1-byte character code, multiply the value of the 1-byte character code by 2. The 2-byte data stored from the beginning of the data conversion table 35 by that value is 1
It is a 2-byte character code corresponding to the byte character code.

Although not shown in the figure, a marker (flag) for storing whether the character code pointed to by the pointer A33 is a 1-byte character code or a 2-byte character code is used here. .. This sign is a pointer A33
If the character code pointed to by is a 1-byte character code, it will be OFF, and if it is a 2-byte character code, it will be ON. This sign is referred to as flag A.

The flowchart of FIG. 2 will be described. The record of the original data file 2 is read into the buffer A31 by the original data input means 3 of FIG. First, initial values are set in the pointer A33 and the pointer B34 (step 12). This initial value is the start address of buffer A31 and buffer B32, respectively. Next, buffer B32
The content of is cleared (step 13). Next, the initial value of the flag A is set. Here, since the beginning of the field read into the buffer A31 is always started from the 1-byte character code, the flag A is OFF.
(Step 14). In addition, buffer B
Since the field after conversion set to 32 always starts with 2-byte character data, a shift-in code is set at the beginning of the converted data buffer (step 15). The pointer B34 is advanced by the length of the shift-in code (here, 2 bytes) (step 16). Next, the character data in the field of the buffer A31 pointed by the pointer A33 is examined (step 17). If there is a shift-in at this time, a character code of 2-byte type will be generated from that point, so flag A is turned on (step 1
8). On the contrary, if there is a shift-out, a 1-byte character code is generated from that point, so the flag A is turned off (step 19). At the time of shift-in and shift-out, data is not set in the buffer B32 and the pointer A33
2 is added to the pointer A33 for advancing to the next character (step 20). When the shift-in or shift-out is not performed, the state of the flag A is judged (step 21). If the flag A is ON, it is a 2-byte character code, so 2 bytes of the data is set as it is (step 2
2). Then, 2 is added to the pointer A33 to advance the pointer A33 to the next character (step 23). If the flag A is OFF, the character code is a 1-byte character code. Therefore, the corresponding 2-byte character code is extracted from the conversion table 35 based on the value of the character code pointed to by the pointer A33, and the buffer pointed by the pointer B34 is displayed. Two bytes are set in the location of B32 (step 24). To advance the pointer A33 to the next character, 1 is added to the pointer A33 (step 25). Then, 2 is added to the pointer B34 in order to advance the pointer B34 to the next position of the buffer B32 (step 26). The above operation is repeated until the data of one field is completed (step 2
7). When the conversion of one field is completed, shift-out is set at the position pointed by the pointer B34 (step 28). Then, the pointer B34 is advanced by the shift-out length (here, 2 bytes) (step 2).
9). The above processing from step 14 to step 29 is repeated for the number of fields to convert data for one record (step 30).

Next, the data edit processing unit 7 for outputting the contents of the record of the intermediate file 6 output by the data format conversion unit 1 as described above will be explained. The converted record is input from the intermediate file 6 by the intermediate file input means 8. Since the input record is in a format that can be edited as it is, it is edited in a format that can be displayed by the next data editing means 9, and is displayed or printed on the output device 11 by the output means 10.

Example 2. In the first embodiment, the 1-byte character is directly converted to the 2-byte character. This would double the length of 1-byte characters. In the present embodiment, attention is paid to the one-byte type kana characters having a dakuten and a semi-dakuten, and these are converted into a two-byte type character of dakuon and semi-dakune. FIG. 5 is a flowchart in which the processing for dakuten and semi-dakuten is added to the flowchart used in the first embodiment. In the figure, reference numerals 36 to 41 denote added processing steps, which correspond to the processing steps described in the text. Further, reference numerals 21, 24, 25 and 26 correspond to processing steps having the same numbers in the flowchart of FIG.

Next, the operation will be described. The state of the flag A is judged (step 21), and if the flag A is OFF, the 1-byte character code is converted (step 2).
4). At this time, the 1-byte character code pointed to by the pointer A33 is checked (step 36). That letter
If it is a kana line, a sa line, or a ta line, a pointer A33
Determine whether the next character pointed to by is a dakuten (step 3)
7). If it is a dakuten, a first constant is added to the 2-byte character code pointed to by the pointer B34 (step 38). When the 1-byte character pointed by the pointer A33 is the Kana line, it is determined whether the next character pointed by the pointer A33 is a dakuten or a half-dakuten (step 39). If it is a dakuten, a first constant is added to the 2-byte character code pointed to by the pointer B34 (step 38). If it is a semi-voiced point, a second constant is added to the 2-byte character code pointed by the pointer B34 (step 40). At this time, the constant is a 2-byte character code JIS kanji code (JIS X0208).
If it is, the value is 1 for the dakuten and 2 for the semi-dakuten.
This is based on the fact that the kana character codes of JIS are defined in the order of the kana character code of “Kiyon”, “Dakuon”, and “Semi-dakuon”. Then, if the processing of the above-mentioned dakuten and semi-dakuten is performed, 2 is added to the pointer A33 (step 41). If the processing of dakuten and semi-dakuten is not performed, 1 is added to the pointer A33 (step 2).
5). Then, 2 is added to the pointer B34 (step 26).

Example 3. In the first embodiment, when converting 1-byte kana characters to 2-byte kana characters, all kana characters are converted to katakana characters. This is because only katakana exists as 1-byte kana characters. Both katakana and hiragana are defined for 2-byte kana characters. Therefore, in this embodiment, two 1-byte Kana characters are used.
Convert to byte-based Hiragana characters. FIG. 6 is a flowchart in which hiragana conversion is added to the flowchart used in the first embodiment. In the figure, reference numerals 42 to 44 denote added processing steps, which correspond to the processing steps described in the text. Further, reference numerals 21, 24, 25 and 26 correspond to processing steps having the same numbers in the flowchart of FIG.

Although not shown in the figure, a mark (flag) which is turned on / off by an external instruction is used. This sign turns off when converting to katakana, and turns on when converting to hiragana. This sign is referred to as flag B.

Next, the operation will be described. The state of the flag A is judged (step 21), and if the flag A is OFF, the 1-byte character code is converted (step 2).
4). To advance the pointer A33 to the next character, 1 is added to the pointer A33 (step 25). Next, flag B
The state of is determined (step 42). If the flag B is ON, it is determined whether the 2-byte character code pointed to by the pointer B34 is in the kana character range (step 43). If it is a kana character, the constant is subtracted from the value of the 2-byte character code pointed to by the pointer B34 (step 44). The constant at this time is the difference between the 2-byte character codes of Katakana and Hiragana if the 2-byte character code is the JIS Kanji code (JIS X0208), and all characters have the same value. This is because in the JIS kanji code of JIS, katakana and hiragana are arranged in the same line with a certain value. Then, 2 is added to the pointer B34 (step 26).

As described above, according to this data conversion processing method, a field in which a 1-byte character code and a 2-byte character code are mixed, which is difficult to handle conventionally,
Since all are unified into 2-byte character codes, the work of editing fields is lightened. This will be described with reference to FIG.

FIG. 7 is an explanatory diagram for explaining a process of dividing a field into two equal parts. In the figure, reference numeral 48 is an example of a field in which a 1-byte character code is unified into a 2-byte character code by the data conversion processing method according to the present invention. Reference numeral 49 is a field for storing the first half of the bisected data. A field 50 stores the latter half of the data obtained by dividing the data into two equal parts. 2 in field 48
This is a process of equally dividing and storing in the first half partial field 49 and the second half partial field 50, respectively. The processing at this time simply divides the data of the original field 48 into two. Since the data of the first half portion always ends with the 2-byte character code, the shift-out is added to the end of the first half portion field 49. Also, since the latter half portion always starts with the 2-byte character code, the shift-in is added to the beginning of the latter half portion field 50. The process of adding the shift code can be fixedly performed. Further, since the boundary that is divided into two is always a break between characters, there is no need to judge the internal character code. Further, the length of the field becomes longer than that of the mixed field 45 in FIG. 8, but the lengthening of the field can be suppressed by performing the dakuten and semi-dakuten processing according to the second embodiment of the present invention.

Although not described in the embodiment, since it is clear that the field 48 always uses a 2-byte character code, there is no need for shift-in and shift-out, so the field length is made shorter. be able to.

Further, as in the third embodiment, a constant is subtracted from a 2-byte character code by externally giving an instruction to convert a katakana character to a hiragana character. It is also possible to convert to the character.

In the embodiment, the original data file 2 is input and is output as the intermediate file 6. However, after inputting the original data file 2 and converting the data in the data converting means 4, it is left as it is. It may be passed to the data editing means 9 and output from the output means 10 to the output device 11.

[0038]

As described above, according to the present invention, in a data processing device for processing data in which a 1-byte character code and a 2-byte character code are mixed in one field, the 1-byte character code is used. Based on the character code of, a table that can refer to a 2-byte character code corresponding to the character is provided, and conversion means for converting a 1-byte character code into a 2-byte character code using this table is provided. It has been prepared so that when a 1-byte character code and a 2-byte character code are mixed in one field, the 1-byte character is replaced with the corresponding 2-byte character. Fields in which 1-byte character code and 2-byte character code are mixed are unified into 2-byte character code. There is an effect that the work of the burden becomes lighter.

Furthermore, when the kana character code of the 1-byte system is followed by the dakuten and semi-dakuten code, a predetermined constant is added to the 2-byte system character code corresponding to the 1-byte system kana character to obtain 1 byte. By replacing the Kana character of the system and the subsequent voiced sound and semi-voiced sound with the corresponding 2-byte character of voiced sound and semi-voiced sound, the length of the field can be suppressed and the data length that can be stored in the field can be reduced. The effect is that it can be made as long as possible.
