Description

[Detailed Description of the Invention] [Summary] A document processing method for a document processing device that handles a mixture of full-width and half-width characters. When there is a space for a half-width character at the end of a line and the following character is full-width, an extended display area is provided and the full-width character is displayed using the half-width character at the end of the line and the following extended area. This method improves processing efficiency by eliminating the need to forcibly insert spaces or the like in the trailing half-width position, and makes the display easier to read due to natural display.

[Industrial application field]

The present invention relates to a document processing method in a document processing device that handles a mixture of full-width characters and half-width characters, particularly in a Japanese document processing device.

In particular, in Japanese document processing devices, it is desired that so-called full-width characters in a predetermined font shape and so-called half-width characters occupying half the character positions can be freely mixed and used in one document.

In such a system that allows both types of characters to be mixed, it is further desirable to be able to arrange the full-width characters so that they start from the same arbitrary position as the half-width characters.

[Prior art and problems to be solved by the invention] FIG. 2 is a block diagram showing an example of the configuration of a document processing device.

By executing the program 3 loaded into the memory 2, the processor 1 receives and processes commands and character information input from the keyboard 4, sequentially sets documents in the buffer 5 on the memory 2, and stores the documents in the buffer 5. The content and necessary messages are displayed on a display device 6 such as a so-called CRT display.

Further, the processor 1 sequentially stores the document created on the memory 2 in a storage device 7 such as a disk storage device, and also loads a portion of the document from the storage device 7 into the memory 2 in response to a command for processing. In addition to documents, the storage device 7 stores programs,
Memorizes dictionaries, character patterns, etc. for kana-kanji conversion,
The processor 1 reads them as needed and uses them for processing, controlling the display device 6, and the like.

For example, as shown in FIG. 3, the buffer 5 is a storage area having an appropriate number of rows 10 corresponding to the display screen of the display device 6, and each row 10 has a predetermined number of half-width characters. It consists of a character field 11 that can hold character codes corresponding to characters.

The processing device 1 can display a part of the document by sending a portion of the buffer 5 within a predetermined number of lines determined by the specification from the keyboard 4 to the display device 6. The part containing the line that is being changed is displayed.

For example, when using the well-known one-code system, half-width characters are represented by 8 bits and full-width characters by 16 bits, so each character field 11 is represented by one 8-bit byte, and a full-width character is represented by two consecutive characters. Represent using fields.

For example, as shown in ■ in Figure 4, full-width characters rAJ, full-width characters "B", half-width characters rlJ, r2J, r31 are input to buffer 5, and only one half-width character position 12 remains at the end of the line. , the cursor (indicated by a chisel in the figure) is located at the half-width character position 12, indicating that input can be made from that position.

However, for example, if you enter the full-width character "C" in this line, there is no position to display a full-width character on this line, so "blank" will be forced into the half-width character position ■2, as shown in ■. The character code is placed so that the input character C is displayed at the next character position, which is the first two half-width character position of the next line.

As a result, if insertion/deletion, etc. is performed in this document and the position of the blank space at half-width character position 12 is moved, it is not possible to identify whether the blank space was intended by the document creator or not. In order to fill in the blank space, the creator must perform the "delete" operation.

Furthermore, if the full-width character rCJ in the example above is rewritten to some kind of half-width character, or if the lines are connected and printed on one line, it will remain blank regardless of the creator's intention.

In order to solve this problem, there is a method in which the blank code at half-width character position 12 is replaced with a specific code determined to indicate an invalid character position.

Another possible method is to divide the display of one full-width character into two and display the first half at half-width character position 12 and the second half at the first half-width character position of the next line, but in both cases, input is specified. Since the characters are not completely displayed at the positions, there is a problem in that the naturalness of the screen display is impaired for the operator.

[Means for solving problems]

FIG. 1 (al indicates the configuration of a document processing apparatus of the present invention, and FIG. 1 (bl indicates the flow of processing of the present invention).

In FIG. 1 Tal, 20 is a buffer for displaying documents, and the buffer 20 consists of a line display area 21 and an extended display area 22. 23 is a display device that displays all or part of the buffer 20, and 24 is a program that includes the processing shown in FIG.

FIG. 1(b) shows the flow of processing for setting a character code in the buffer 20, and 30 to 34 are processing steps.

[Function] The line display area 21 of the buffer 20 has the same configuration as the buffer 5, and the extended display area 22 is an area adjacent to the last character position of each line of the line display area 21, for example, an area for each half-width character. The display device 23 is a display device having a display screen expanded to display an appropriate number of lines including the line display area 21 and the extended display area 22.

When one character to be set at the current cursor position in the buffer 20 is determined in step 30 by input from the keyboard 4, the first half of the character code is set at the current cursor position in step 31, and it is determined in step 32 whether it is a full-width character.

Only in the case of full-width characters, the pointer at the cursor position is advanced to the next half-width character position in the line in step 33, and the second half of the character code is set at that position in step 34.

In step 35, it is determined whether the pointer at the cursor position is before the end character position of the line in the line display area 21, and if it is before the end of the line, the pointer is advanced to the next character position in the line in step 36.

If the pointer is at or beyond the end of the line, stay.

At step 37, the pointer is updated to point to the first character position of the next line.

As described above, the full-width character starting at the half-width character position at the end of the line in the line display area 21 is set at the end of the line and the half-width character position in the extended display area 22, and on the corresponding display device 23, the half-width character that starts at the end of the line is set to the half-width character position. displayed in the form

Therefore, there is no need to forcefully insert blank spaces, etc., and the display can be easily viewed.

〔Example〕

In FIG. 1 (al), a buffer 20, a display device 23,
The program 24 has the same functions as the conventional buffer 5, display device 6, and program 3 except as described below.
Further, the other parts indicated by the same reference numerals as in FIG. 2 are the same as those described above.

The line display area 21 of the buffer 20 has the same configuration as the buffer 5, and the extended display area 22 has a memory area adjacent to the last character position of each line of the line display area 21, for example, an area for each half-width character. ! area and thereby buffer 20
The structure is as illustrated in (1) and (2) in FIG. 4.

The display device 23 is a display device having a display screen expanded so that an appropriate number of lines such as those shown in (1) and (2) in FIG. 4 can be displayed. Further, the display device 23 may be one in which the extended portion is made visible by so-called scrolling of the screen.

Assume that one character to be set at the current cursor position in buffer 20 is determined in step 30.

In such a case, when a single character for new or insertion is input from the keyboard 4, the character string is inserted or deleted in the document already set in the buffer 5, and
There are cases where you want to sequentially move character strings on a buffer.

When one character to be set is determined in step 30, first in step 31 the first half of the character code is set at the half-width character position pointed to by the pointer indicating the current cursor position, and then in step 3
2 determines whether it is a full-width character.

Identification of full-width or half-width is made, for example, by the most significant bit of the character code, and the two bytes below the result bit for the full-width character code, and one byte for the half-width character code, are the valid code.

If it is a half-width character, the character code setting is completed and the process immediately proceeds to step 35.

Only in the case of full-width characters, the pointer at the cursor position is advanced to the next half-width character position in the line in step 33, and the second half of the character code is set at that position in step 34. As a result, if the cursor is located at the half-width character position at the end of the line, the pointer points to the extended display area 22, and the second half character code is set there.

In step 7 step 35, the pointer at the cursor position is identified before the end character position of the line in the line display area 21, and if it is before the end of the line, in step 7 step 36 the pointer is moved to the next character in the line. Advance to position.

If the pointer is at or beyond the end of the line, the pointer is updated in step 37 to point to the first character position of the next line.

In other words, if the cursor is at the half-width character position at the end of the line when inputting this character, the pointer will remain at the last character position if the input character is a half-width character, but if it is a full-width character, the pointer will stay at the last character position due to the processing described above. If so, it points to the next character position beyond the end of the line as described above, so both cases are detected and the cursor is displayed at the beginning of the next line as the next inputtable character position. Make it. In this way, the extended display area 22 is never displayed with a cursor as an inputtable character position.

As described above, the full-width character starting at the half-width character position at the end of the line in the line display area 21 is set at the end of the line and the half-width character position in the extended display area 22, and on the corresponding display device 23, the half-width character that starts at the end of the line is set to the half-width character position. displayed in the form

■ in FIG. 4 is the state of the buffer 20 of the present invention corresponding to ■. Here, as above, when the double-byte character "C" is input, by executing the process shown in Figure 1 above,
The buffer 20 becomes as shown in FIG. So, for example, a string in this document.

There is a deletion, and A is placed in the related position as shown in Figure 4 (■) above.
Even when l3- is moved, no blank space is inserted.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, in a document processing device that can handle a mixture of full-width characters and half-width characters, there is no need for special processing of vacant half-width character positions at the end of lines, and Since a natural display screen can be generated, this has the effect of improving the performance and ease of use of the device.
