Figure 19 shows the text buffer after the main text has been corrected.
DBUF main text content and table of contents data buffer
An example of the contents of the IPBUF table of contents information table is shown below.
Comparing the content of the main text and the table of contents information table shown in Figure 12 when creating the text with this Figure 9, it is found that
In Figure 2, Chapter 1 was only one page, but due to editing work to the main text, Chapter 1 in Figure 19 is now two pages. Also, when creating the text in Figure 12, there was a chapter called "Caution" as Chapter 4, but in Figure 19 after the main text was revised, Chapter 4 was deleted, and the previous Chapter 5 was replaced with Chapter 4. Chapters have been changed.

Figure 20 shows the revised text shown in Figure 19,
This shows the contents of the table of contents to be output after changes have been made according to the table of contents information table. Corrections made in the main text are automatically made to the table of contents, and the content of the table of contents matches the current content of the main text.

FIG. 21 shows the contents of the table of contents buffer IB which stores the contents of the table of contents shown in FIG.

22 to 33 are flowcharts showing an example of the control procedure of the apparatus to which the character processing method of the present invention shown in FIG. Figure 23 shows the procedure for creating a text, Figures 24, 25, and 26 show the procedure for creating a table of contents according to the table of contents information table, and Figures 27 to 33 show the procedure for creating a text. The procedure for re-editing a created sentence is shown. In addition, STEP 1~ in the diagram
STEP135 shows each step of the flowchart.

Next, an example of the operation of the apparatus to which the character processing method of the present invention shown in FIG. 1 is applied will be described in detail with reference to the flowcharts shown in FIGS. 22 to 33.

This example has two functions: a new sentence creation function and a re-editing function for sentences once created.
It can be started by pressing ED or the re-editing designation key RE (see Figure 5). Therefore, the second
As shown in Figure 2, when the text creation start key ED is pressed (STEP 1), the process of creating a new text (hereinafter referred to as text creation process) is executed (STEP 2), and the re-editing designation key RE is pressed. When is pressed (STEP 3), re-editing processing (hereinafter referred to as text re-editing processing) for the once created text is executed. (STEP 4).

When the text creation start key ED is pressed,
The process moves to a text creation processing routine, and the procedure shown in FIG. 23 is executed. First, before creating a new text, the buffer DBUF for text creation and the buffer IPBUF for creating table of contents information are all cleared, and at the same time, the address of the start position of the buffer DBUF is set in the pointer DBUFP (STEP 11). next,
Register for chapter number counting that determines the number of each chapter
Since we will create CPTNO from Chapter 1, set "1" as the initial value (STEP 12). This chapter number register CPTNO is incremented by 1 each time the creation of one chapter is completed, and maintains the number of the chapter currently being created. Next, it is determined whether the text creation end designation key EDE, which commands the end of text creation, has been pressed (STEP 13). If this designation key EDE is pressed, it means that the text creation has been completed, and the process moves to a table of contents creation processing routine to be described later, and executes the table of contents creation processing (STEP 14). Details of this table of contents creation process are shown in flowcharts shown in FIGS. 24 to 26, which will be described later.

On the other hand, if the writing end designation key EDE is not pressed down, it is determined whether the chapter start designation key CPS, which commands the start of a chapter, is pressed down (STEP 15). Since the key CPS is always pressed at the beginning of a chapter, if the key CPS is pressed,
Create a new table of contents information table for the new chapter (STEP 16). Here, it is assumed that the table of contents information table has the contents shown in FIG. 10A described above. At that time, in STEP 16, the necessary location for this table of contents information table is created in the table of contents data buffer.
Then, set the current chapter number set in the chapter number register CPTNO in the table of contents information table just secured (STEP 17).
Next, a pointer indicating the address position of the text buffer DBUF corresponding to the current chapter number of the text body is set in the table of contents information table (STEP 18). A pointer indicating the buffer position is stored in the pointer DBUFP, and is updated in STEP 23 after the key input process (STEP 21) for inputting characters into the text buffer DBUF is completed. This situation is shown in Figure 11 above.
Arrows indicate pointers corresponding to the beginning positions of each chapter in the text buffer DBUF from the table of contents information table corresponding to each chapter in the table of contents data buffer IPBUF. Then the page count register PGCNT
Set "1" as the initial value of the number of pages for each chapter (STEP 19).

Next, the chapter end specification key to command the end of the chapter.
Determine whether CPE is pressed down (STEP 20). The period until this key CPE is pressed means inputting characters for one chapter, so if the chapter end designation key CPE is not pressed,
In STEP 21, input processing from the keyboard KB is performed. Key input from the keyboard KB is processed by the keyboard controller KBC and sent to the keyboard KB.
Stores the code corresponding to the key pressed in the text buffer DBUF. In this STEP 21, key input processing for one character is performed, and a code for one character is set in the text buffer DBUF. The details of this character input processing will be shown in the flowchart of FIG. 26, which will be described later. When the key input for one character is completed, it is then determined whether or not the character input for one page is completed (STEP 22). Whether or not character input for one page has been completed is determined according to conditions such as the number of characters or the number of lines. If you have not finished entering characters for one page, return to STEP 20 and press the
If there is no CPE key input, the same key input process as described above is repeated in STEP21. If the key input for one page is completed, "1" is added to the value of the page count register PGCNT (STEP 23), and the process returns to STEP 20 and continues the key input processing in STEP 21 until the key CPE is pressed. and
Repeat the addition process in STEP23.

When the chapter end designation key CPE is pressed,
The page number of the chapter stored in the page number count register PGCNT is set in the page number of the table of contents information table of the current chapter number (STEP 24). Next, input processing for the chapter title of the table of contents information table is executed. The title of this chapter is similar to the key input in the main text, which is input from the keyboard KB, and the code corresponding to the input key is
Enter the current chapter number in the chapter title section of the table of contents information table (STEP 25). However, in this example, the chapter title is a maximum of five characters. Next, add "1" to the value of the chapter number register CPTNO that stores the chapter number to set the next chapter number (STEP 26), then return to the above-mentioned STEP 13 and press the text creation end designation key EDE. Repeat the same process as described above in STEP 15 to 26 until it is lowered. The above-mentioned FIG. 11 shows a state in which the process has been executed up to STEP 26 and the input up to the second chapter has been executed, and the next chapter has not been input. By repeating the above sentence creation procedure, all sentences as shown in FIG. 12 described above are created. After the text buffer DBUF and table of contents data buffer IPBUF shown in FIG. 12 are created, the text creation end designation key EDE is pressed.

When the text creation end designation key EDE is pressed, the process moves to the table of contents creation processing routine shown in FIGS. 24 and 25, and the basic format of the table of contents shown in FIGS. Create to. That is, on the table of contents buffer IB shown in FIG. 14, character codes corresponding to "eye" and "next" are set in addresses IB9 and IB12, respectively, as the basic format of the table of contents (STEP 31). Next, "1" indicating the first chapter is set as the initial value number of the chapter in the register CPIPT indicating the chapter number currently being processed (STEP 32).
Next, a register indicating the number of the first page of each chapter
“1” as the first page number of Chapter 1 in CPCONT
(STEP 33). Next, the table of contents
Register indicating character set position of each chapter on IB
In IBP, address IB41 as the table of contents position of Chapter 1.
Set "41" to indicate (STEP 34).

Next, the values of the register CPTNO, which stores the numbers of all the chapters of the main text, and the register CPIPT, which indicates the chapter number currently being processed, are compared (STEP 35). If the value of register CPIPT becomes larger than the value of register CPTNO, it means that the main table of contents creation process has finished, so save each data text body, table of contents, and table of contents information table shown in STEP 36, 37, and 38. Execute processing. That is, STEP 36 to 38
, move the contents of each buffer DBUF, IB and IPBUF to disk DISK.

By comparing the value of register CPIPT and the value of register CPTNO, the value of register CPIPT is compared to the value of register CPTNO.
If it is less than or equal to the value of CPTNO
Move to STEP 39, and in the subsequent steps create table of contents data corresponding to each chapter of the main text and create a table of contents buffer.
Set the transfer to IB. First, register
Search the table of contents data buffer IPBUF for the table of contents information table that matches the chapter number set in CPIPT. Since the table of contents information table has a chapter number at the beginning of each table of contents information table, a table in which the chapter number in this table matches the value of the register CPIPT is searched for (STEP 39).
By finding this table position, it becomes possible to know the contents of the table of contents to be created for that chapter. Next, in order to set the chapter number in the table of contents, the value of the chapter number register CPIPT currently being processed is converted into a numerical code (STEP 40). Next, the code indicating the text number just converted and the "th" and "th" character codes to be added to it are set in the data buffer (table of contents one-line buffer) LB for one chapter (STEP 41). In the example shown in FIG. 17 described above, each code of "th" is set in the address LB2, "1" in the address LB4, and "chapter" in the address LB5.

Next, add the section that shows the chapter title to a one-line buffer in the table of contents.
Set to LB. The chapter title is stored as a string of character codes in the table of contents information table of the chapter currently being processed. Change the character code of the title in this table of contents information table to the address LB8 to LB1 of the buffer LB.
Set it to position 2 (STEP 42).

Next, a register indicating the number at the beginning of the current page
Convert the chapter first page maintained by CPCONT into a numerical code (STEP 43). Add this numerical code to the addresses LB16 and LB17 of the buffer LB.
Set it as a character code at the position (STEP 44). By the above processing of STEP39 to STEP44, the contents of the table of contents of the chapter indicated by the register CPIPT are set in the one-line table of contents buffer LB having a table of contents data area for one chapter as shown in FIG. 17 described above. Now, the value of register CPIPT is “1” and the first
When the chapter is processed, the table of contents shown in FIG. 17 will be created.

Next, transfer the table of contents data for one chapter that you just created to the table of contents buffer IB and set it. In this example, the positions to be set are the data positions of buffer IB at addresses IB41 to IB60, IB81 to IB100, and IB1.
21~IB140, IB161~IB180, IB20
1 to IB220, the buffer LB addresses LB1 to LB20 are the table of contents buffer position register.
Set the table of contents buffer IB indicated by IBP, that is, IB (IBP) to IB (IBP+20) (STEP 45). In the above-mentioned Figure 18, the table of contents data set in the one-line table of contents buffer LB for Chapter 1 is stored at address IB41 of the table of contents buffer IB.
~IB60 position is shown.
Next, "40" is added to the value of the table of contents buffer position register IBP to set the position where the next table of contents data should be set (STEP 46). Next, "1" is added to the value of the register CPIPT indicating the chapter number currently being processed as the chapter number to be processed next (STEP 47). Through the above processing, the table of contents for one chapter has been set in the table of contents buffer, and the register for the next chapter has been set. Next, return to STEP 35 again and continue as described above until the value of register CPIPT exceeds the value of register CPTNO.
Repeat steps 35 to 47.
By repeating the processing of STEP 35 to STEP 47, the table of contents of all chapters is set in the table of contents buffer IB.
The above-mentioned FIG. 16 shows the table of contents buffer IB in which table of contents data for all chapters are set. When this table of contents creation process is completed, the text creation process ends, and control is returned to the main routine shown in FIG. 2.

Furthermore, to explain the character input process shown in FIG. 26, first, a key code from the keyboard KB is input (STEP 51). Then the keyboard
Convert the key code input from KB to a character code for text (STEP 52). Next, the converted character code is set to the buffer position indicated by the register DBUFP indicating the current input position of the text buffer DBUF (STEP 53). this
Through the processing of STEP51 to STEP53, the character code for one character is set in the text buffer DBUF. Next, the value of register DBUFP is counted up by one character so that register DBUFP points to the next character input position (STEP 54). Thereafter, the process returns to the main routine of text creation processing shown in FIG. 23 and proceeds to STEP22.

In this way, by using the processing procedure shown in Figures 23 to 26, the table of contents information table created during text creation can be used to automatically create a table of contents in the table of contents buffer IB when specifying the end of text creation. .

Next, a function for re-editing a text using the text created by the above-described text creation function, a table of contents, and a table of contents information table will be explained with reference to the flowcharts shown in FIGS. 27 to 33.

As described above, when the re-editing designation key RE is pressed, the process moves to the text re-editing processing routine shown in FIG. 27 and subsequent figures, and the text re-editing process is executed. First, the text, table of contents, and table of contents information table created by the text creation process described above are called from the disk DISK and set in the random access memory RAM. At that time, the text will be converted to a text buffer DBUF,
The table of contents information table is the table of contents data buffer IPBUF.
Next, the table of contents data is set in the table of contents buffer IB in the same way as it was set during text creation processing (STEP 61).

Then a register indicating the chapter number being processed
After setting CPIPT to "1" indicating the first chapter (STEP 62), the pointer (address value) indicating the first position of the chapter in the table of contents information table corresponding to the chapter number set in register CPIPT is currently processed. Set the register DBUFP pointing to the location of the text buffer DBUF to be written (STEP 63). this
The processing in STEP 63 has set the starting position of the text buffer DBUF. Next, a pointer indicating the beginning position of the chapter in the table of contents information table corresponding to the chapter number next to the chapter number set in register CPIPT is set to register NDBUFP indicating the position of the next chapter in text buffer DBUF (STEP 64). ). Register NDBUFP is described below.
Text buffer currently being processed in STEP78
Used to determine whether the pointer to DBUF, DBUFP, has moved to the next chapter position.

Next, it is determined whether the re-editing end designation key REE has been pressed (STEP 65). When the re-editing end designation key REE is pressed, it means that the text correction, addition, and deletion processing has been completed, so the process moves to the table of contents creation processing routine and executes the table of contents creation processing (STEP 66). This table of contents creation process is shown in Figure 24 and 2, which were explained in the text creation process above.
A process similar to that shown in FIG. 5 is performed to create a new table of contents in the table of contents buffer IB and disk DISK according to the table of contents information table created in conjunction with the re-editing process such as text correction. When this table of contents creation processing is completed, the present reediting processing is completed and control is returned to the main routine shown in FIG. 22. On the other hand, if a key other than the re-editing end designation key REE is pressed, text modification, addition, and deletion processing shown in detail in FIGS. 28 to 33 is executed (STEP 67). This process in STEP 67 is repeatedly executed until the key REE is input.

The procedure for modifying, adding, and deleting the above-mentioned sentences will be explained with reference to FIG. 28 in order.

In the text correction, addition, and deletion processing, first, it is determined whether or not the chapter start designation key CPS has been pressed (STEP 71). When this key CPS is pressed, the chapter end designation key CPE is pressed.
Execute the key input of the title to be changed and change the title of the chapter currently being processed (STEP72 and
STEP73). When the chapter end designation key CPE is pressed, a register CPIPT indicating the chapter number currently being processed is pressed.
Change the chapter title with the chapter number that matches the value to the new chapter title you just entered (STEP 74). this
When STEP72 to STEP74 are executed, this correction, addition, and deletion processing is completed, and the process returns to the main routine shown in FIG. 27.

If a key other than the chapter start designation key CPS is pressed, it is determined whether the "→" pointer progression key PA is pressed (STEP 75). If it is determined in STEP 75 that the pointer progress key PA has been pressed down, it is determined whether the current processing position of the text buffer DBUF is the final position of the text buffer DBUF using the value of the text buffer pointer DBUFP (STEP 76 ). If it is the final position,
This correction, addition, and deletion processing is ended without executing anything, and the process returns to the main routine shown in FIG. 27. If the position indicated by the pointer DBUFP is not the final position of the text buffer DBUF, the value of the pointer DBUFP is set to the position of the next character (STEP 77).

Next, the sentence buffer pointer that you just changed
It is determined whether the value of DBUFP has reached the start position of the next chapter by comparing it with the value of the register NDBUFP indicating the start position of the next chapter (STEP 78).
If the value of the text buffer pointer DBUFP has not reached the beginning of the next chapter, finish the process of moving the text buffer pointer DBUFP forward by one character, and finish this correction, addition, and deletion process. 27th
Return to the main routine shown. pointer DBUFP
If the value of has reached the beginning of the next chapter, processing will move on to the next chapter, so add "1" to the value of register CPIPT indicating the chapter number currently being processed.
Set it as the chapter number of the next chapter (STEP 79). Next, the value of the register CPIPT is transferred to the register NDBUFP indicating the starting position of the next chapter, and the starting position data is reset (STEP 80). When STEP80 is executed, this modification, addition, and deletion processing is completed, and the process returns to the main routine shown in FIG. 27.

In STEP75 above, pointer progress key
If it is determined that a key other than PA has been pressed, the process moves to STEP 81 in FIG. 29, and it is determined whether the "←" pointer back key PB has been pressed. When this key PB is pressed, the value of the text buffer pointer DBUFP changes to the text buffer pointer DBUFP.
Determine whether the starting position of the DBUF is indicated (STEP 82). If the value of the pointer DBUFP indicates the beginning position of the text buffer DBUF,
This correction, addition, and deletion processing is ended without executing anything, and the process returns to the main routine shown in FIG. 27. pointer
If the value of DBUFP does not indicate the beginning position of the text buffer DBUF, the pointer DBUFP is set to the position of the previous character (STEP 83). next,
It is determined whether the changed value of the pointer DBUFP has become the starting position of the chapter currently being processed by comparing it with the value of the register CPIPT (STEP 84).
If the value of the pointer DBUFP does not indicate the beginning position of the chapter currently being processed, this correction, addition, and deletion processing is terminated and the process returns to the main routine of FIG. 27. When the position indicated by the pointer DBUFP becomes the beginning position of the chapter currently being processed, the register
Decrease “1” from the current chapter number of CPIPT,
After moving the process to the previous chapter (STEP85),
This correction, addition, and deletion processing is completed and the process returns to the main routine shown in FIG. 27.

If a key other than the pointer back key PB is pressed, it is determined whether a key INS for commanding insertion of one character is pressed next (STEP 86). If the key INS is pressed, character insertion processing, which will be described in detail in Section 31 below, is executed (STEP 87).
If a key other than the key INS has been pressed, it is determined whether the key DEL, which instructs deletion of one character, has been pressed (STEP 88). that key
If DEL is pressed, character deletion processing, which will be described in detail in FIGS. 32 and 33, is executed (STEP 89).

If a key other than the one-character deletion designation key DEL is pressed, it is determined whether the character key KB1 is pressed (STEP 90). When a key other than the character key KB1 is pressed, the correction, addition, and deletion processing is immediately terminated, and the process returns to the main routine shown in FIG. 22. When the character key KB1 is pressed, the key code of that key is converted into the character code of the sentence (STEP 91). Next, the character code converted in the previous STEP 91 is set at the address position of the text buffer DBUF indicated by the text buffer pointer DBUFP (STEP 92).

Next, the next character position is set in the pointer DBUFP (STEP 93). In subsequent STEP94 to STEP98, the same processing as in STEP76 to STEP80 described above is executed. That is, in STEP94, it is determined whether the value of the pointer DBUFP is the final position of the buffer DBUF, and if it is the final position, this process ends; otherwise, in STEP95, the pointer DBUFP is set to the position one character ahead. . Next, in STEP96, pointer
Determine whether the value of DBUFP has reached the start position of the next chapter or not, and if it has not reached the start position of the next chapter, proceed with the process by one character and end this process,
When you have reached the beginning of the next chapter, STEP97
Add “1” to the current chapter of register CPIPT with
After setting the start position of the next chapter in register NDBUFP in STEP98, this process is ended and the process returns to the main routine shown in FIG. 27.

Next, character insertion processing will be explained with reference to FIG. In the character insertion process, first the pointer
Buffers from the address position indicated by DBUFP
Move the contents of DBUF one character at a time to the address position after the buffer DBUF (STEP 101). next,
By character insertion processing in STEP101, register
It is determined whether the page of the chapter pointed to by CPIPT has increased by one page (STEP 102). If an increase of one page occurs, the number of pages in the table of contents information table pointed to by register CPIPT is counted up (incremented) by "1" (STEP 103). Next, key input processing for insertion characters input from the keyboard KB is executed (STEP 104). Next, the key code obtained through the input processing is further converted into a character code (STEP 105). Next, the character code converted in the previous STEP 105 is set at the buffer DBUF position indicated by the pointer DBUFP (STEP 106). Next, change the register NDBUFP to the position one character backward (STEP 107). Next, search the chapter number of the final table of contents information table from the buffer IPBUF.
Set it to CPTNO (STEP 108) and register
The chapter number currently being processed indicated by CPIPT is set in CPIPT1 (STEP 109). Next, it is determined whether or not the processing for all chapters has been completed (STEP 110), and if all the chapters have been completed, this processing is ended and the routine returns to the routine of FIG. 29. If the processing for all chapters has not been completed, the head pointer of the table of contents information table indicated by register CPIPT1 is shifted backward by one character (STEP111).
Next, after adding "1" to the value of register CPIPT1 to make the value of CPIPT1 the next chapter number (STEP112), the process returns to STEP110 again. these
Repeat steps 110 to 112 to change the start pointers for all chapters.

Finally, character deletion processing will be explained with reference to FIGS. 32 and 33. In the character deletion process, first, each of the subsequent text buffer contents DBUF is moved forward by one character from the address position indicated by the pointer DBUFP (STEP 121). Next, it is determined whether characters for one page have been deleted (STEP 122). If one page has been deleted, the number of pages in the table of contents information table pointed to by register CPIPT is counted down (decremented) by "1" (STEP 123). Next, the previous
It is determined whether the number of pages counted down by 1 in STEP 123 has reached "0" (STEP 124).
If it is determined in STEP124 that the number of pages is "0", the chapter number of the final table of contents information table is set in register CPTNO (STEP125), the value of register CPIPT is set in register CPIPT1 (STEP126), and the next Then, the value of the register CPTNO and the value of the register CPIPT are compared to determine whether processing for all chapters has been completed (STEP 127). When the processing for all chapters is completed, the main character deletion process ends,
Return to the routine of FIG. 27. If processing for all chapters is not completed, a register is added to the table of contents information table area of the chapter number indicated by register CPIPT1.
Value obtained by adding “1” to CPIPT1 (CPIPT1+
1) Sets the table of contents information table for the chapter number indicated by (STEP 128). Next, "1" is added to the register CPIPT1 to set the next chapter number (STEP 129), and the process returns to STEP 127 again, and the processing of STEP 127 to STEP 129 is repeated until the processing for all chapters is completed. By repeating the above steps STEP 127 to STEP 129, one chapter's table of contents information table is deleted.

In STEP122, if it is determined that one page has not been deleted, the register
Change the value of NDBUFP to the position of buffer DBUF one character before (STEP 130). In the following STEP131 and STEP132, the above-mentioned STEP125 and
Perform the same processing as in STEP126, set the chapter number of the final table of contents information table in register CPTNO, and set the value of register CPIPT in register CPIPT1. Next, it is determined whether processing for all chapters has been completed (STEP 133). When the processing for all chapters is completed, the main character deletion processing is completed and the process returns to the routine shown in FIG. 27. If the processing for all chapters has not been completed, the head pointer of the table of contents information table indicated by register CPIPT1 is shifted forward by one character (STEP 134). Then register the next chapter number
After setting CPIPT1 (STEP135). again
Return to STEP133 until all chapters are processed.
The process of STEP133 to STEP135 is repeated to complete the process of shifting the pointer pointing to the beginning of all chapters forward by one character.

Figure 19 above shows an example in which the content of the text in the buffer DBUF has been corrected by the re-editing process described above, but in this example, one page of text is added to Chapter 1, which was one page at the time of creation. In addition, the chapter titled "Notes" that existed as Chapter 4 at the time of creation was deleted by re-editing, and the chapter titled "End" in Chapter 5 at the time of creation was changed. has been revised in Chapter 4. Therefore, the table of contents information table (IPBUF) shown in Figure 19
Among these, changes and corrections will be required for Chapters 1, 4, and 5 due to the addition of corrections to the main text. Since one page of text has been added to the first chapter of the main text, the number of pages at chapter number "1" in the table of contents information table is changed from "1" to "2". Also, due to the deletion of Chapter 4, the operation of deleting the table of contents information table of Chapter 4 and correcting the chapter number that was originally Chapter 5 from "5" to "4" was performed while editing the main text. executed. When the re-editing end command key REE key is pressed, this table of contents information table is created, so the state of the text and table of contents information table becomes as shown in FIG. 19.
Therefore, the table of contents output from the printer PRT thereafter becomes as shown in FIG. in this way,
According to this example, the table of contents and the table of contents information table are automatically corrected and saved as the text is corrected.

In addition, in this example, to specify the beginning and end of each chapter, the special keys CPS and CPS of the keyboard KB are used.
Although the instructions are given using CPE,
By entering the keywords of this text using the normal character keys, you can enter the specified key CPS and CPE.
It is also possible to do this. For example, by inputting keywords together with chapter titles, it is possible to reduce the effort required to press designated keys.

Furthermore, in this example, the table of contents data for each chapter is limited to the number of pages and the title, but it is of course possible to add other necessary information. Furthermore, in this example, we used the unit of an entire sentence and a chapter as a division of that sentence, but
It can also be applied when considering units of sections that are further divided into chapters, and the same effect can be obtained. In this way, since the present invention considers and constructs a text in terms of a certain editing unit and a set of the units, it can be executed over many layers.

(Effects) As explained above, according to the present invention, the table of contents is automatically created based on the completion of the creation of the main text, and there is an effect that there is no need to perform a new task for creating the table of contents. It will be done.

Furthermore, according to the present invention, the table of contents is automatically corrected and changed based on the completion of proofreading (editing) the main text, so it is only necessary to edit the main text, and the table of contents cannot be corrected or changed. The effect is that there is no need for additional work.
