Abstract

PURPOSE:To improve the processing efficiency by automatically preserving information on the alteration history of a document, and then easily and surely performing alteration management and preventing the processing speed from decreasing when a document is taken out. CONSTITUTION:When document data are preserved, an attribute code adding means adds the attribute code of the history information, and then the information on the alteration history of the document is stored in the document data. A history table generation part 9, a table expansion part 10, and a table storage part 12 are added to this document processor. The table expansion part 10 has a function for generating a history list from the history table. A history table generation part 9 generates the history information from the document data, the table storage part 12 only stores the generated history table temporarily, and the history table itself is not necessary Namely, information regarding the alteration of the document is preserved in the real data on the document and neither a special management table nor an alteration history file is used.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a document processing apparatus having a document editing function such as a Japanese word processor, and more particularly, when an existing document is modified to create a new version of the document. A document processing device that eliminates a change history table and files by holding a document created in the state of actual data with an attribute code indicating the change content added to the changed portion of the document for each version .

[0002]

2. Description of the Related Art In a document processing apparatus such as a word processor, a document creating method is often used in which the data of a created document is stored and the document data is newly modified and used as needed. Several methods have already been proposed for managing the change history when modifying such an existing document. For example, a modification table or a file that has been modified for one unit of modification. Have been proposed.

Specifically, the operation of the operator with respect to the existing document is stored as a separate file (command file), and from the existing document and the command file,
Judgment of correction points and management of changes (for example, JP-A-1-
No. 142858). Further, various editing functions are realized by providing a table and files of document data and change history (for example, Japanese Patent Laid-Open No. 62-54346).

In addition to this management method,
There is also known a method of sequentially changing the stored document from the first correction history data when retrieving the latest document (after the last change). However, in these methods, since it is necessary to manage the data in addition to the data, the management and storage of the document data becomes complicated.

Further, although the history of change history is saved, there is waste such as saving the changed document data for each change, and when the number of changes increases, the processing speed also decreases. There is inconvenience. On the other hand, a method of displaying a corrected portion and printing with a mark is also proposed.

That is, a dedicated correction registration / cancellation key is provided on a keyboard or the like, and a correction symbol is added to the registered data by operating this key (for example, Japanese Patent Laid-Open No. 58-169239). This method has a problem that it requires a dedicated pointing device and a dedicated command, and is not fully automated.

[0007]

SUMMARY OF THE INVENTION According to the present invention, these inconveniences in a conventional document processing apparatus having a change history management function, that is, a change table and a change operation file are required, or a dedicated instruction device or It solves many inconveniences such as the need for instruction commands and the reduction in processing speed.

[0010]

According to the present invention, firstly,
A means to input a document consisting of data such as characters and areas,
In a document processing device comprising means for storing / saving these document data, means for outputting the stored document, and means for displaying / reediting the document, the document data is stored in a previously created version. Included is attribute code addition means for adding an attribute code of history information indicating that there is information on the change history of the document by adding the attribute code of the history information by the attribute code addition means when the document data is saved. It is stored in the document data.

Secondly, in the first document processing apparatus, the specified revision of the document is output using the stored change history information.

Thirdly, in the first document processing apparatus, the stored change history information is used to output only the documents of different pages between the two designated versions.

Fourthly, in the first document processing apparatus, the stored and saved change history information is output as a list as a change history list.

Fifthly, in the first document processing apparatus, the changed portion is marked using the stored change history information.

Sixthly, in the first document processing apparatus, the stored revision history information is used to display the designated version of the document during editing.

[0016]

In the present invention, attention is paid to the fact that there are only two types of actual document change processing: insertion or deletion, and information relating to document changes (to modify history storage history codes and characters) The information such as the attribute assigning code) is stored in the actual data of the document together with the text data, thereby eliminating the need for using a special management table or change history file. First, the history saving attribute code used in the document processing apparatus of the present invention will be described in detail. A control code (hereinafter referred to as a control code) for adding an attribute to an underlined or shaded character will be described later.

FIG. 2 is a diagram showing an embodiment of the code structure of the history saving attribute code.

As shown in FIG. 2, the history saving attribute code (hereinafter referred to as history code) is composed of information of an insert ID, a delete ID, an insert date and time, and a delete date and time.
These pieces of information are an insertion ID that indicates that the subsequent document data has been inserted, a deletion ID that indicates that the subsequent document data has been deleted, and the edit date and time.

The ID is a numerical value starting from "1",
It is increased by one edit break. Generally, this ID represents the version of the document. However, it is assumed that the insertion ID of "0" represents the end of the document data, and the deletion ID of "0" represents that the document data has not been deleted.

Such history codes are used one by one independently (cannot be nested) and are valid until the next history code is input. Further, the break of editing, that is, the updating of the ID currently being edited is performed by the user when registering a document, by instructing whether to register during editing or finalized registration as a version. In the latter case, At the time of final registration as a version, the editing ID is "1".
increase.

[Embodiment 1] This embodiment mainly corresponds to the invention of claim 1, but is also related to the inventions of claims 2 to 6.

FIG. 1 is a functional block diagram showing an embodiment of the main configuration of the document processing apparatus of the present invention. In the figure, 1 is a display unit, 2 is a key input unit, 3 is a pointing device, 4 is an operation unit, 5 is a control unit, 6 is a data storage memory during editing, 7 is a plate making unit, 8 is a document data processing unit, Reference numeral 9 is a history table creation unit, 10 is a table expansion unit, 11 is a document storage unit, 12 is a table storage unit, 13
Is an output control unit, and 14 is an output device.

In terms of hardware, the document processing apparatus of the present invention shown in FIG. 1 is a conventional apparatus in that a history table creating section 9, a table expanding section 10, and a table storing section 12 are added. Is different. The function of each part is as follows. The display unit 1 displays the contents of the document being edited,
It is a display that displays operational messages and the like in a visible pattern.

The key input section 2 has a function of receiving an input from the keyboard. Similarly, the pointing device input unit 3 has a function of receiving an input from the pointing device.

The operation unit 4 controls inputs from various input devices and gives instructions to the control unit 5. The control unit 5 has a function of controlling the entire system. The editing data storage memory 6 is a storage device for storing the document data being edited and for processing the stored data.

The version creating section 7 has a function of assembling various versions from document data. The document data processing unit 8
It has a function of document data and document creation, and controls the processing of stored document data according to the format information. The history table creation unit 9 creates history information from document data.

The table expanding section 10 has a function of creating a history list from the history table. Document storage unit 1
Reference numeral 1 is a storage device for storing documents. The table storage unit 12 temporarily stores the history table and performs processing.

The output control unit 13 has a function of controlling output data and the output device 14. Output device 14
Is an output means for making a hard copy such as a printer or a facsimile.

As described above, in the present invention, the information regarding the change of the document is stored in the actual data of the document, and no special management table or change history file is used. That is, the newly added history table creation unit 9 creates history information from the document data, and the table storage unit 12 only temporarily stores the created history table. The history table itself is unnecessary.

Next, in the document processing apparatus of the present invention,
The internal processing at the time of insertion / deletion will be described in detail. In the following description, for ease of understanding, the insertion ID and the deletion ID of the history code will be represented by “R13” or the like as a one-digit numerical value.

For example, this "R13" indicates that the following data has been inserted in the first edition and deleted in the third edition. The document data structure of the document processing apparatus in this embodiment is as shown in FIGS. A specific process of creating a document will be described by comparing an example of changing a document with internal data (actual data) at that time.

FIG. 3 is a diagram showing an example of a change of a document and internal data at that time in the document processing apparatus of the present invention. In the figure, A31 is the first edition document, A32 is the actual data of the first edition document, A33 is the document to be inserted into the first edition document, A34 is the second edition document, and A3.
Reference numeral 5 indicates the actual data of the second edition document, A36 indicates the document to be deleted from the second edition document, A37 indicates the third edition document, and A38 indicates the actual data of the third edition document.

First, when a document of the first edition as shown by A31 in FIG. 3 is created, the actual data (internal data) of the document of the first edition becomes A32. That is, in the internal data, as in A32, "R10" (insertion ID) is entered as the history code at the time of the first edition at the beginning of the document, and then the character string data of the first edition document A31 is arranged. Finally, "R00" (a deletion ID, a deletion ID of "0" indicating that it has not been deleted) is entered.

Next, as the second edition, the first edition document A31
On the other hand, the document is inserted as indicated by A33. In other words, "Kakikokeko" is inserted between "O" and "Ka" (A33).

In this case, first, the history code "R20" is inserted at the insertion position, and then the character string data to be inserted is inserted. Finally, the history code “R10” before the insertion position (at the time of the first edition) is inserted.

As a result, the actual data of the document becomes as shown by A35. That is, the character string data “Kakikukeko” (A33) inserted in the second edition has the history code “R20” indicating that it was inserted in the second edition at the beginning,
The subsequent character string data is changed to a state in which “R10” indicating that there is no change from that in the first version is added.

This second edition document A34 (actual data is A3
Regarding 5), it is assumed that deletion is performed like A36 in the third edition. In FIG. 3, it is assumed that two characters of the character string data “Tata” (A36) are deleted from the document A34.

In this case, before the deletion start position (second
The history code “R10” of the (version point) is acquired, and the history code “R13” with the deletion ID of the code set to 3 is A36
Put in the beginning of the character string data of "Tata", and at the end,
The character string data thereafter is the history code “R10” indicating that there is no change from that before (in this case, the first version and the second version).
Since there is no change in the version, "R10" indicating that the data was created in the first version is entered).
Therefore, as the third edition document, the character string data “Tata” (A36) is deleted from the document A34, and the third edition document A37 (actual data is A38) is displayed.

That is, in the third version of the actual data A38, the "ta" of A36 is deleted from the second version of the actual data A35, but the first version is inserted before the character string data "ta". A history code “R13” that is (created) and deleted in the third edition is followed by a history code “R10” that indicates that the subsequent character string data is data created in the first edition. Are added to each. In this way, when the deletion process for the past edition is performed, A
As shown in 37, the deleted character string data disappears from the display screen, but the history code “R
13 ”is only added, and in reality, the character string data to be deleted is not deleted and is retained as it is.

In the example of FIG. 3 described above, the character string data of A33 is inserted into the document A31 created as the first version to change it to the document A34 of the second version, and further the character string data of A36 is added. Is a process for creating the third version of the document A37, and is a case of making a relatively simple change. next,
A case where the deletion process is performed on the newly inserted portion will be described.

FIG. 4 is a diagram showing another example in which the document modification and the internal data at that time are compared in the document processing apparatus of the present invention. In the figure, A41 is the second edition document, A42 is the actual data of the second edition document, A43 is the document deleted from the second edition document, A44 is the third edition document, and A45 is the third edition document. The actual data of is shown.

In FIG. 4, as indicated by A41, the first
In the version document, that is, in the character string data'Aiueo ',
This shows a state in which the character string data “Kakikukeko” with the history code “R20” or less is inserted to create the second version document. Therefore, on the display screen, the character string'Aiueo Kakikuko 'as shown by A41 is displayed.

In this case, the actual data (internal data) is
It looks like A42. When the character string data “EoKaki” shown by A43 is deleted from the second edition document A41 as the third edition, a document as shown by A44 is created. In this state, the document of the third edition has the character string "Akekeko" as shown in A44.

The actual data is, as indicated by A44,
The history code "R13" is inserted before the deletion target character string data "Eo" created in the first edition, and the deletion target character string data "Kakiku" created in the second edition is added. The history code “R23” is inserted into And the second
The history code "R20" is inserted before the document string data "keko" created in the version and left in the third version of the document.

In this way, for example, when the history code already exists in the range to be deleted in the third edition, the code having the deletion code "0" is the ID being edited (the first 1 in the history code).
Change the digit "2" to "3"). In FIG. 4, the first
The history code "R13" is added to the character string created by the version.
In addition, the history code "R
23 "are given respectively.

Therefore, if the internal data (third edition) shown in A45 of FIG. 4 is compared with the internal data (second edition) of A42, the history code "R13" is the character string data "e".
The history code "R20" that was newly inserted just before the existing code was changed to "R23", and the history code "R20"
“20” is newly inserted immediately before the character string data “K”.

On the other hand, if the code is not "0", that is, if it has already been deleted, it is left as it is. Further, the processing of the start point and the end point of the range is similar to that of FIG. 3 described above (when the history code is immediately before the character of the start point of the deleted range,
Similar to the case in the middle of the range).

The history code used in the present invention described above can be summarized as follows. here,
It is assumed that an nth edition document is being created. In this case,
When inserting or deleting, do the following: When inserting, the history code at the cursor position (and range) is "R
If it is "n0", only the document data is inserted as in the normal operation.

On the other hand, when making a change to the document of the nth edition or earlier, for the kth edition of the document to be changed, the number at the time of its insertion (creation) and the number of the changed nth edition are set. The history code “Rkn” indicated by is used. Where k
<N. That is, the nth edition is determined by the presence or absence of n in the history code, and if it is a tens digit,
It is inserted in the nth edition, and if it is the first digit, it indicates that it was deleted in the nth edition.

In FIGS. 3 and 4 described above, only the character string data is created for each version of the document. However, the present invention can be implemented in the same manner even when there are mixed characters such as underlines and shaded characters (control codes for attribute assignment).

FIG. 5 is a diagram showing an embodiment of the correspondence between the screen display of the document and the internal data in the document processing apparatus of the present invention. (1) is the screen display, (2) is the internal data,
(3) indicates a control code for attribute assignment. In the figure, UN
Don means underline start, UNDoff means underline end, NETon means shading start, and NEToff means shading end.

It is assumed that the document shown in FIG. 5A is displayed on the screen. Here, the attribute means a decoration attached to a character, such as underlining or shading.
The internal data (actual data) in this case is, as shown in FIG. 5 (2), data indicating a character code such as a character string or a punctuation mark, an underline start UNDon, and an end UNDoff.
, And a control code with an attribute indicating the start NETon and the end NEToff of shading.

When saving the change history, an attribute code for saving the history is embedded in the document data.
Here, a case where the deletion process is performed on a document having a control code (control code for attribute assignment) will be described.

FIG. 6 is a diagram showing an example of a change of a document having an attributed control code and internal data at that time in the document processing apparatus of the present invention. In the figure, A61 is the first edition document, A62 is the actual data of the first edition document, A63 is the document deleted from the first edition document, A64 is the second edition document, and A65 is the second edition document. Actual data, A66 indicates the inserted attribute code, UND
on is a control code indicating the start of underline, and UNDoff is a control code indicating the end of underline.

In FIG. 6, as indicated by A61, the first
This is the case where a part of the version document, that is, the character string data'Kakikukeko 'is underlined.
The actual data (internal data) in this case is, as indicated by A62, a history code "R10" indicating that the document was created as a first edition document and a history code "R0" indicating the end thereof.
In addition to "0", the control code "UNDon" indicating the start of underline is entered at the beginning of the character string data "Kakikukeko", and the control code "UNDoff" indicating the end of underline is entered at the end. There is.

For this first edition document A61, A63
When the second edition document is created by deleting the character string data “EoKaki” shown in, a second edition document such as A64 is obtained on the display screen. The actual data is A
Change as shown at 65. In other words, the history code "R1
2 ”(history code indicating that it was created in the first edition and deleted in the second edition).

In this case, since the character string to be deleted includes underlined character string data "Kaki", the end of the character string, that is, the second character
At the beginning of the letter'ke 'where underlining starts in the edition,
The history code "R20" and the control code "UNDon" indicating the start of underlining are inserted, and then the history code "R10" is inserted as described in FIG. 3 and FIG. As shown in FIG. 6, when the deletion range includes one of the control codes such as underline and shading, the control code within the deletion range (within the deletion ID “0” area) Attribute document data of) may be inserted at the final position of the deletion range in the order of appearance.

That is, in the case of FIG. 6, since the underlined character string data "Kaki" is within the deletion range, this code (control code "UNDon" indicating the start of underlining) is deleted. The history code "R20" is inserted at the last position of the target character string. As described above, even if the character string to be changed (correction target character string) contains characters with attributes such as underline and shading, the change must be made after the history code. By inserting the control code to instruct, the actual data including the change history of the document can be obtained.

The processing relating to such history code and control code is executed by the document data processing unit 8 in FIG. As described in detail above, in the first embodiment,
By saving the information such as the attribute code (history code) for saving the history of document changes and the attribute control code in the actual data of the document, it is not necessary to use a special management table or change history file. ing.

[0059]

Second Embodiment Next, a second embodiment will be described. This embodiment corresponds to the invention of claim 2.

The second embodiment is characterized in that the history information is automatically extracted from the stored document in the document processing apparatus according to the first aspect. In order to retrieve the nth version of the document from the stored document data including history information, it is sufficient to extract a document having an insertion ID of n or less and a deletion ID of “0” or larger than “n”.

FIG. 7 is a diagram showing an example of the correspondence relationship between the character string data of the first to fourth editions and the changed parts in each edition, and the actual data of the fourth edition. (1) is the first The character string data from the 4th edition to the 4th edition and the changed parts in each edition, (2) is the 4th edition
The actual data of the version is shown. In the figure, A71 is character string data for the first edition, A72 is character string data for the second edition, A73 is character string data for the third edition, A74 is character string data for the fourth edition, and A75 is character for the second edition. Character string data to be inserted in the column, A76 is character string data to be inserted in the character string of the third edition, A77 is character string data to be deleted in the fourth edition, A78
Shows the actual data of the 4th edition.

When the second edition is extracted from the document shown in FIG. 7 (1), the following is done. (Insert ID ≦ 2) AND {(delete ID = 0) OR (delete ID> 2)} The document data associated with the history code that matches is extracted. In the document data A78 of the fourth edition of FIG. 7 (2), history codes satisfying the above conditions are "R10" and "R1".
4 ”and“ R24 ”.

Therefore, when the character strings following these three history codes are extracted, the second version document A72 is obtained. The above-described function, that is, the process of extracting an arbitrary plate is performed by the plate creating unit 7 shown in FIG.
The extracted document is stored in the document storage unit 11 as another document.

As described above, in the second embodiment, the history information can be automatically extracted from the stored document. Therefore, according to the second embodiment, in addition to the effect of the document processing apparatus of the first embodiment (claim 1), any plate can be taken out.

[0065]

Third Embodiment Next, a third embodiment will be described. This embodiment corresponds to the invention of claim 3.

Here, a case will be described in which, for example, different pages of the mth edition and the nth edition (m> n) are extracted from the stored document data including history information. The history code search conditions in this case are as follows: insert ID ≦ n and n <delete ID ≦ m n <insert ID <m and delete ID = 0 (or m <
Delete ID) A history code satisfying any one of the insertion ID = m is searched, and a page including the corresponding history code is output.

For example, when different pages of the second edition and the third edition are extracted from the document of FIG. 7, the conditions are: insert ID ≦ 2, and 2 <delete ID ≦ 3 2 <insert ID <3, And the deletion ID = 0 (or 3 <
Delete ID) Insert ID = 3, and the document data A78 of the fourth edition shown in FIG. 7 (2) above.
Among these, the ones that match this are "R34" and "R30"
Is. Therefore, in the end, the page including the character string "Sashisuseso" is selected.

The above processing is performed by the document data processing unit 8 of FIG.
Run by As described above, in the third embodiment, when the difference page of any two versions of the document is desired, the difference page can be automatically extracted. Therefore, according to the third embodiment, in addition to the effect of the document processing apparatus of the first embodiment (claim 1), it is possible to automatically obtain the difference pages of two arbitrary versions of the document. it can.

[0069]

Fourth Embodiment Next, a fourth embodiment will be described. This embodiment corresponds to the invention of claim 4, but is also related to the invention of claim 1.

The document processing apparatus according to claim 4 is characterized in that, in the document processing apparatus according to claim 1, the work of creating the information of the change history of a document as a list can be automatically performed. There is. To create a change history list of a document, search for a history code other than "R10" in the document, and insert / delete ID of that code for the found code,
The position in the document data and the page and line when the document is expanded are recorded to create a history code table as shown in FIG.

FIG. 8 is a diagram showing an embodiment of the history code table created in the document processing apparatus of the present invention.

As shown in FIG. 8, the history code table is searched for, for example, "insert / delete ID", "classification", "position in document data", "page", and "row". History code (insert ID or delete ID), position in document data, and "number of pages" when expanded to document
And is created using information such as "number of lines"

The process of creating the history code table shown in FIG. 8 is performed by the history table creating section 9 of FIG.
The created table is temporarily stored in the table storage unit 12. Here, as an example, a method of creating a table of a created document as shown in FIG. 9 will be described.

FIG. 9 is a diagram showing a fourth embodiment of the document processing apparatus according to the present invention, which compares a document change with internal data at that time. In the figure, A91 is the first edition document, A92 is the actual data of the first edition document, and A93.
Is a document to be inserted in the first edition document, A94 is a second edition document, A95 is actual data of the second edition document, A96 is a document to be inserted in the second edition document, and A97 is a third edition document. Document, A9
Reference numeral 8 indicates actual data of the third edition document, and B1 to B3 indicate divided character string data.

FIG. 9 shows the case where the revisions from the first edition to the third edition have been made, and when a document of the first edition of the character string data'aahh 'as shown by A91 in FIG. 9 is created,
The actual data (internal data) of this first edition document is A92.
become that way. That is, the internal data is the history code at the time of the first edition at the beginning of the document, as in A92.
"R10" (insert ID) is entered, and finally, a history code "R00" (delete ID, delete ID of "0" indicating that it has not been deleted) is entered.

Next, in this first edition document A91, A93
If you insert the character string data "Good" shown in
The display screen looks like this, and the actual data (internal data) of the second edition document becomes like A95. In addition, this second
In the version document A94, the character string data "Uu" shown in A96
Inserting "" causes a display screen like A97, and the actual data (internal data) of the third edition document becomes "A98".

That is, when the character string data “UU” is inserted at the middle position of the character string inserted in the second edition when the third edition is revised, the inserted character string data “nice” in the second edition is divided. Will be done. Generally speaking, this case means that if the (n + 1) th edition character string is inserted in the middle of the nth edition inserted character string, the nth edition insertion character string will be divided. become.

That is, when simply looking at the history code from the beginning, the insertion operation of the character strings "A93" and "A96" is actually performed only twice. In the actual data, the character string data is “good” (B1),
Since it is judged that "Uu" (B2) and "Good" (B3) have been inserted three times in total, an incorrect history table is created. Therefore, in the fourth embodiment, the search for the insertion ID is recursively performed to avoid such an erroneous detection.

These processes are performed by the history table creating section 9 shown in FIG. 1, and the created table is temporarily stored in the table storage section 12. The operation of creating a table according to the fourth embodiment will be described with reference to a flow. First, the insertion ID will be described.

FIG. 10 is a flow chart showing the main processing flow of the search of the insert ID when creating the history table in the document processing apparatus of the present invention. In the figure, # 1 to # 4 indicate steps.

In step # 1, the next history code is searched. The process proceeds to step # 2 to check whether the insertion ID = 0. If the insertion ID = 0, the flow of FIG. 10 ends.

On the other hand, if the insertion ID is not 0,
The process proceeds to step # 3 to check whether the insertion ID = 1. If the insertion ID = 1, the process returns to the previous step # 1 and the same process is repeated.

As a result of checking in the previous step # 3, if the insertion ID is not 1, the process proceeds to step # 4. In step # 4, the registration subroutine is executed to insert I
History codes other than "1" for D are once registered in the table, the process returns to the previous step # 2, and the same processing is repeated.

The above processing is performed by inserting the insertion ID in step # 2.
This process is repeated until = 0, and when the search for all history codes is completed, the flow of FIG. 10 is terminated. Next, the registration subroutine will be described.

FIG. 11 is a flow chart showing the flow of main processing of table registration at the time of searching the insert ID shown in FIG. In the figure, # 11 to # 16 indicate steps.

At step # 11, history codes other than the insertion ID "1" are registered in the table. Step # 12
Then, the insertion ID is retained for comparison with the next history code.

The process proceeds to step # 13 to search for the next history code. In step # 14, the size relationship between the insertion ID of the history code and the insertion ID held in the previous step # 12 is compared.

If the insertion ID is the same, the process returns to step # 13 to search for the next history code. Also,
As a result of checking in step # 14, if the insertion ID of the next history code is larger than the insertion ID held in step # 12, it means that the character string has been divided, so proceed to step # 15. The registration subroutine is executed, and the process returns to step # 14. In this way, the search continues recursively.

On the other hand, as a result of checking in step # 14, if the insertion ID of the next history code is smaller than the insertion ID held in the previous step # 12, a series of insertion character strings with the insertion ID. Represents the end of
The process proceeds to step # 16 to exit the search loop. By performing the above steps # 11 to # 16, as shown in FIG. 9, even if a series of character strings is divided by the newly inserted character string, as shown in FIG. The history code insertion ID can be searched, and an accurate history code table can be created.

When the creation of the table for insertion is completed, the table for deletion is created by the same process. Even in the case of this deletion ID, the search is recursively performed. The deletion retrieval processing is shown in the flows of FIGS. 12 and 13 below.

FIG. 12 is a flow chart showing the flow of main processing for searching for a deletion ID when creating a history table in the document processing apparatus of this invention. In the figure, # 21 to # 24 indicate steps.

At step # 21, the next history code is searched. In step # 22, it is checked whether the insertion ID = 0. If the insertion ID = 0, the flow of FIG. 12 ends.

On the other hand, if the insertion ID is not 0,
In step # 23, it is checked whether the deletion ID = 0. If the deletion ID = 0, the process returns to the previous step # 21 and the same process is repeated.

As a result of checking in the previous step # 23, if the deletion ID is not 0, the process proceeds to step # 24. At step # 24, the registration subroutine is executed to once register the history code having a deletion ID other than "0" in the table, the process returns to step # 22 again, and the same processing is repeated.

The above-mentioned processing is executed in step # 22 to insert I
This process is repeated until D = 0, and when the search for all history codes is completed, the flow of FIG. 12 is terminated. Next, the registration subroutine will be described.

FIG. 13 is a flow chart showing the flow of main processing of table registration at the time of searching for the deletion ID shown in FIG. In the figure, # 31 to # 36 indicate steps.

In step # 31, history codes other than the delete ID "0" are registered in the table. Step # 32
Then, the deletion ID is retained for comparison with the next history code.

In step # 33, the next history code is searched. In step # 34, the deletion ID of the history code is compared with the deletion ID held in the previous step # 32.

If the deletion IDs are the same, the process returns to the previous step # 33 to search for the next history code. Also,
As a result of checking in step # 34, if the deletion ID of the next history code is larger than the deletion ID held in step # 32, the process proceeds to step # 35, the registration subroutine is executed, and step # 34 is executed again. Return to. In this way, the search continues recursively.

On the other hand, as a result of checking in step # 34, if the deletion ID of the next history code is smaller than the deletion ID held in the previous step # 32, the process proceeds to step # 36 and the search loop is executed. Get out. By performing the above steps # 31 to # 36, the history code deletion ID for each version can be searched, and an accurate history code table can be created.

Next, a process of creating a history for each version will be described. To create a history table for each version, insert / delete I
Sort D by smallest number.

If a history table for each page is desired, sort by that value. Then, data is taken out in order from the head of the created table, and a table as shown in the next FIG. 14 is created.

FIG. 14 is a diagram showing an embodiment of a document revision history table created by the document processing apparatus of the present invention. In the figure, C1 is the edition, C2 is the modification date, C3 is the classification, and C4.
