Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a display control method in a word processor having a proofreading function.

(Prior Art) In general, in word processors, when control information that requires expansion, such as tabs or indents, is used in a document file, the print result naturally has a predetermined blank area due to the expansion of tabs or indents. generated. On the other hand, the display device for example
When displaying on a CRT, blank display is performed by expanding tabs or indents in the same way as above. As a result, as shown in Figure 1, there is a mixture of white space in the original sense that is displayed due to the presence of white space characters in the document, and white space that is displayed as a result of expanding tabs or indents as described above. It became extremely difficult for the operator to identify these blank spaces, which caused the following operational problems.

In other words, a case will be explained in which, using known proofreading means, a cursor displayed on a CRT points to, for example, a blank display area, and a corresponding blank character string in the document file is deleted by keyboard input. . In this case, if the area subjected to the proofreading operation is an original blank character as described above, the blank character is deleted as specified by the proofreading operation, and the character string that follows is moved forward by the number of deleted characters, Deletion is executed correctly. However, the blank display area resulting from expanded tabs or indents cannot be deleted because there is no corresponding blank character string in the document file. In such a case, the above-mentioned deletion operation is not performed on the blank display area, but
This must be done for control information such as tabs or indentation that is the cause of this. Therefore, the blank display area caused by expansion of tabs, indents, etc. cannot normally be subject to proofreading operations.

Further, if there is a line feed code or a page feed code in the document file, the remaining part of the same line or the remaining part of the same line and the remaining lines are displayed blank. For this blank area, there is no corresponding blank string in the document file,
As in the case described above, it cannot be subject to calibration operations. However, proofreading is possible for the leading blank display position of the blank display area based on the line feed code or page break code because the line feed code or page break code exists in the document file.

Furthermore, in document proofreading, a window area is set that is independent of text information existing outside the document, such as drawings or photographs that may be inserted later. However, since the part where character information is not input inside the area set by the window area is not distinguished,
The operator could not understand the meaning of the secured area from the display screen.

(Problem to be Solved by the Invention) As mentioned above, in the past, all blanks with different meanings were displayed as the same blank in the proofreading operation.
There was a problem with the operation.

Therefore, the present invention treats the blank area that occurs in the document as a result of setting the window area to be an area that has a different meaning from the area where characters are not input or the blank character code area that occurs outside the window area. The problem to be solved is to provide a display control method for word processors that can be recognized by users.

[Structure of the Invention] (Means for Solving the Problem) This invention provides means for displaying a mark unique to the window area at each column position of each line within the window area when displaying a document including a window area. The present invention is characterized in that the area within the window area in which no character information exists is displayed separately from the area outside the window area.

(Function) According to the above configuration, a special mark is displayed at each digit position of each line in the area where character information is not input inside the area set as the window area, so the operator can mark the window area on the display screen. Recognizable.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. Note that this embodiment is a case where the present invention is applied to a Japanese word processor.

FIG. 2 is a block diagram showing the structure of a novel Japanese word processor to which the present invention is applied.
The Japanese word processor shown in the figure includes a processing device 10, a main memory 11, and a disk storage device 1.
2, a kanji pattern memory 13, a CRT control device 14, a CRT display device 15, a printer control device 16, and a printer device 17,
It is constituted by an input device such as a keyboard device 18. The main memory 11 and the disk storage device 12 are connected to the processing device 10 via a memory bus 19. In addition, a kanji pattern memory 13, a CRT control device 14, and a printer device 16
and keyboard device 18 are connected to processing device 10 via I/O bus 20. Furthermore, the above
The CRT control device 14 and printer control device 16 are
Kanji pattern memory 13 via KPM bus 21
It is connected to the.

The keyboard device 18 includes keys for alphanumeric characters, kana characters, symbols, and functions. In addition, the kanji pattern memory 13 contains commonly used character patterns (characters here include not only kanji but also alphabetical characters, numbers, kana, symbols, etc., and the characters listed below have the same meaning. ) is memorized. Furthermore, the disk storage device 12 stores all character patterns and dictionaries,
Furthermore, document files consisting of character information and control information are stored. Furthermore, the main memory 11 contains a program for searching for characters stored in the kanji pattern memory 13 and the disk storage device 12, a program for searching for document files stored in the disk storage device 12, and kana-kanji. Algorithm for conversion,
Furthermore, various control programs including a program for changing (proofreading) the content of the document file are stored.

The operation of the Japanese word processor described above will be briefly explained below. First, the user inputs the name of the document to be displayed using the keyboard device 18 by key operation. By this key input operation, the processing device 10 searches for the address of the disk storage device 12 where the specified document is stored, and stores the address in the main memory 11. Then, the contents of the document are read from the disk storage device 12 according to this address. The processing device 10 determines the content of the document, as will be described in detail later, and sends a character code (including a blank display code, etc.) according to the result of this determination. Furthermore, the processing device 10 searches for the address of the kanji pattern memory 13 or the disk storage device 12 in which the corresponding character pattern information is stored, based on the character code. In this search, the kanji pattern memory 13, which stores a copy of a portion of the contents of the disk storage device 12 and is comprised of, for example, a high speed random access memory, is first searched. If the corresponding character pattern is not stored in the kanji pattern memory 13, the disk storage device 12 is searched, the character pattern is read out, and written in the kanji pattern memory 13 to be stored in advance. Writing of this character pattern is performed by replacing the old character pattern in the variable area of the kanji pattern memory 13.

Then, the address information retrieved above is transferred from the processing device 10 to the CRT control device 14. The CRT control device 14 reads a character pattern from the kanji pattern memory 13 based on the address information and displays it on the CRT display device 15. The operator visually checks the contents of the display, and if there is a location to be calibrated, operates the keyboard device 18 to move the cursor to the corresponding location on the display screen. Then, by key-inputting the contents to be proofread, the kanji pattern memory 13 or the disk storage device 12 is read as described above.
address is searched. The address information thus searched is transferred to the CRT control device 14, and thereby the display contents of the CRT display device 15 are calibrated. At the same time, the above key input will cause
The address data (document storage address) in the main memory 11 and the contents of the document file stored in the disk storage device 12 are also proofread.

Then, when the keyboard device 18 is operated and a key input for printing is performed, address information is transferred from the processing device 10 to the printer control device 16 as in the case of display. Printer control device 1
Reference numeral 6 reads a character pattern from the kanji pattern memory 13 based on the above address information, and prints out, for example, a proofread document using the printer device 17.

Next, the display control method of the present invention implemented in the above-mentioned Japanese word processor will be explained with reference to the flowchart shown in FIG.

First, when the operator specifies a document to be displayed using the keyboard device 18, the processing device 10 reads out the contents of the document in accordance with the above-described procedure and stores it in a predetermined work area in the main memory 11. . The processing device 10 performs the following processing based on the content of the document stored in the main memory 11.

That is, the processing device 10 extracts the first data (one character data) from the document stored in the work area in the main memory 11 (step S1). Based on this one-character data, the processing device 10 checks whether the next display position on the CRT display device 15 is over a so-called window (step S2). Here, the window refers to a blank area into which, for example, a drawing or a photograph can be inserted after printing a document, and the above-mentioned window area is specified using the keyboard device 18. Control information such as this window is stored in an area of the disk storage device 12 that is different from the area where text information is stored. Further, the correspondence information between the character information and the control information is stored in another storage area of the disk storage device 12, for example.

If the next position to be displayed is over a window, that is, if control information to be blank printed (displayed) using a predetermined area as a window is detected, the processing device 10 waits until the window in the same line ends. That is, the processing device 10 generates a special code for displaying a specific visible display symbol "+" by the number of corresponding blank display positions (step S3). Then, the processing device 10 extracts the next character (step S3). S4).

On the other hand, if there is no window, the processing device 10 checks whether the next display position to be displayed is within the blank display area created by expanding the indent (step S5). If the next position to be displayed is within a blank display area due to indentation, a special code is generated to replace this blank display area with, for example, a display symbol "" (step S6). Then, similar to the above, steps S4 and S2 are performed in this order.

On the other hand, if it is not within the blank display area due to indentation, the processing device 10 checks whether the next display position to be displayed is within the blank display area generated by expanding the tab (step
S7). If the next position to be displayed is within the blank display area created by the tab, a special code is generated to replace this blank display area with, for example, a display symbol "▼" (step S8). Then, similar to the above, steps S4 and S2 are performed in this order.

On the other hand, if it is not within the blank display area due to the tab, the processing device 10 checks whether the next display position to be displayed is subject to a line feed, that is, whether the character data is a line feed code ( Step S9). If it is a line feed code, a special code is generated to replace and display the start position of the blank display area with a display symbol "▼", for example. Then, the processing device 10 continues to generate a blank character code so that the remaining display area on the same line is displayed blank (step S10). Then, as described above, steps S4 and S2 are performed in this order. Note that the next character of the line feed code will be displayed on the CRT display device 15 as the first character of the next line.

On the other hand, if the character data is not a line break code, the processing device 10 checks whether the next display position to be displayed is subject to a page break, that is, whether the character data is a page break code (step 1).
S11). If it is a page break code, a special code is generated to replace the leading position of the blank display area with, for example, a display symbol "".
Then, the processing device 10 continues to generate a blank character code (step
S12). Then, similar to the above, steps S4 and S2 are performed in this order. Note that the next character of the page break code is displayed when display of the next page is requested.

On the other hand, if the character data is not a page break code, the processing device 10 checks whether the character data is a blank character code (step S13). if,
In the case of a blank character code, a special code is generated to replace the blank display position with, for example, a display symbol "" (step S14). and,
Similar to the above, steps S4 and S2 are performed in this order.

On the other hand, if the character data is not a blank character code, the processing device 10 sends the character data at that time as it is as a character code. Then, similar to the above, steps S4 and S2 are performed in this order.
The processing device 10 is configured to repeatedly perform the above-described operation for a predetermined number of character data in a document file.

Based on the character code sent in this way, the processing device 10 searches for an address in the kanji pattern memory 13 or the disk storage device 12 where the corresponding character pattern information is stored, as described above. The processing device 10 then transfers the address information retrieved above to the CRT control device 14. The CRT control device 14 reads the character pattern from the kanji pattern memory 13 based on the address information, and causes the CRT display device 15 to display the character pattern as shown in FIG. 4, for example.

In this way, blank characters, line feed codes, page break codes, tab spaces, indent spaces, etc.
As shown in the figure, areas that were previously displayed as blank are now displayed with visible display symbols. In FIG. 4, the display symbol "-" represents a cursor.

In the above-mentioned embodiments, areas that were conventionally displayed simply as blanks are replaced with different display symbols depending on the cause. blank character)
Any display that can distinguish between areas that cannot be used (for example, tab spaces, indent spaces, etc.) is sufficient. It goes without saying that conventional blank display can also be performed. In addition, the location to be calibrated can be identified on the CRT using the cursor movement keys of the keyboard device 18.
The explanation has been given of the case where the instructions are given on the display screen of the display device 15, but the instructions may also be given using a pen, for example, and the point is that the operator determines the calibration location by visually observing the content displayed on the display screen. , any word processor equipped with means for proofreading the relevant portions may be used. Further, although the case where the present invention is applied to a Japanese word processor has been described, it goes without saying that the present invention can be applied to any word processor including an English word processor as long as it is equipped with the above-mentioned proofreading means.

In addition, the present invention is not limited to the embodiments described above, and it goes without saying that various modifications can be made without departing from the gist of the invention.

[Effects of the Invention] As detailed above, according to the present invention, a special mark is displayed at each digit position of each line in the area where character information is not input inside the area set as the window area, so that the operator can You can recognize that this area on the screen is an area set as a window area.
