Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing apparatus for use in, for example, a word processor or various computers to input and edit a document.

[0002]

2. Description of the Related Art Generally, a Japanese word processor as a document processing apparatus has a format setting function and enables setting and changing of a document format such as the number of characters per line and a line feed pitch. In addition, such formatting affects the setting area in the document from the line where the cursor is to the position immediately before the line where the format is changed, or the end of the document when the format is not changed. It is set as the range of formatting. 22A and 22B show
The setting area affected by the format setting is shown in FIG. 9A when the format is changed after the cursor in the middle of the document, and in the figure FIG. If not.

Some Japanese word processors having the above-mentioned format setting function have a format search function and a format unifying function. In such a Japanese word processor, the format after the cursor is changed by the format search function. In addition to retrieving the changed next line, the format unifying function unifies all the formats throughout the document.

[0004]

However, with the above-described conventional Japanese word processor's format setting function, it is not possible to change the setting of only an arbitrary range at once.
There is a problem that it takes time and labor and work efficiency is poor. 23A to 23C show, as an example, a method in which the character size of the text is 9 points and only the title is set to 12 points. The figure (a) is a figure which shows the state before a setting, and the figure (c) is a target state. First, move the cursor to the title line and set 12 points by formatting. Then, the state as shown in FIG. 11B is obtained, so that the cursor is moved to the first line of the text and the format is set again to 9 points. As described above, when the format is changed from the initial state of FIG. 7A to the target state of FIG. 7C, the format setting must be performed twice.

Further, the conventional retrieval processing by the format retrieval function retrieves a line in which even one item is changed, out of several items of format information such as the number of characters per line and line feed pitch. For this reason, when the number of format changes is complicated and complicated, the search operation must be repeated many times in order to search for the target format change line, which causes a problem of poor work efficiency. .

Further, since the conventional unifying process by the unifying function is to unify all the formats over the entire document, it is not possible to unify an arbitrary format or only a certain area. . For this reason, conventionally, since all such operations are manually performed by the user, there is a problem in that the work efficiency is poor and there is a possibility of being overlooked.

Further, the conventional Japanese word processor does not have a function of replacing the format. For this reason,
The format replacement operation has a problem that the line whose format has been changed is searched for by the format search function and the user manually replaces each line, resulting in poor work efficiency and possible oversight. is doing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIGS.
The explanation is based on the following. In this embodiment, the case where the document processing device is applied to a Japanese word processor will be illustrated.

As shown in FIG. 1, the Japanese word processor according to the present embodiment controls the operation of each constituent member of the apparatus to execute a program (Central CPU).
Processing Unit) 1. This CPU1 has
A RAM (Random Access Memory) 2 that stores various data such as document data including characters and symbols and a ROM (Read Only Memory) 3 that stores a control program are connected to each other.

Further, the CPU 1 as described above includes a printer 4 for printing document data, a display device 5 for displaying document data, and a keyboard 6 for inputting information such as document data by a user's key operation. , A floppy disk (hereinafter referred to as FD) 7 for loading / saving document data, and an IC (Integrated Circuit) card 8 respectively include a printer controller 9, a display controller 10, a key interface 11, an FD controller 12, and an IC. It is connected via the card interface 13.

A document data storage area for storing and storing document data is formed in the RAM 2. As shown in FIG. 2, the document data stored in this document data storage area is assigned a serial number (address) in units of 2 bytes (1 byte = 8 bits) from the beginning. Stores the entire format data. The entire format data is a format for the entire document such as paper size and paper orientation, and cannot be changed in the middle of the document. The whole format data is set only at the beginning of the document data. Further, since the total format data includes two data, that is, the paper size and the paper direction, the data length of the overall format data is 2 addresses (constant).

Addresses 3-6 and addresses 24-27
Format data is stored in each. This format data includes the format code, the number of points (size) of characters,
It is composed of four types of data including the number of characters per line and the line feed pitch, and these data can be changed even in the middle of a document. In this case, the format data is inserted at the changed location. However, in this embodiment, the format cannot be changed in the middle of the line, and the format data is always inserted at the beginning of the line.

The above-mentioned format code is for distinguishing between the format data and the character data, and after this format code, 3 addresses indicate that the format data is stored. A code that is not used in the JIS code or the like is assigned to such a format code. Character data is actual character data such as kanji, kana and symbols. Such character data has a variable data length, and one address is assigned to each character.

In the following description, the word "address" indicates the address of the document data storage area, and this document data storage area is referred to as "D".
() ”, For example, D (3) indicates the content of address 3 of the document data.

In the ROM 3, a setting area designation routine for designating a setting area in a document of a document format based on the user's designation at each position of the area designation start and the area designation end and a user designated document item. A specified format search routine that searches for the change position, a specified format replacement routine that replaces the setting value of the user-specified document item, and a specified format unification routine that unifies the setting value of the user-specified document item are programmed respectively. ing. And
The ROM 3 constitutes the setting area designating means, the designated format searching means, the designated format replacing means, and the designated format unifying means of the present invention.

FIG. 3 shows variables for storing each address RS / RE of the area designation start and the area designation end for designating the format setting area. Further, FIG. 4 shows variables such as the pointer P used for realizing the present embodiment, and these variables are secured in the variable area in the RAM 2 when the formatting function is executed. Is initialized to.

The difference between the variables shown in FIG. 3 and the variables shown in FIG. 4 is that the variables shown in FIG. 4 are secured when the formatting is executed, whereas the variables shown in FIG. The point is that it is already secured and initialized before execution.

With the above arrangement, the format setting process in the designated area in the Japanese word processor will be described below.

The keyboard 6 is provided with an "area designation" key. When the user moves the cursor and inputs the "area designation" key to an arbitrary position of the document displayed on the display screen, the area designation is performed. The address of the cursor position is stored in the start address RS, and at the same time, the area designation mark is displayed at that position.

When the second "area designation" key input is made at another place, the area designation mark is displayed at the cursor position and the address at the cursor position is compared with the value of the area designation start address RS. However, the smaller one is stored in the region designation start address RS, and the larger one is stored in the region designation end address RE.

Here, as an example, how the document shown in FIG. 5 is stored will be described. The “□” marks on the third and fifth lines of the document shown in FIG. 5 indicate that the area is designated at that position. The marks A on the first and sixth lines of the document represent line feed characters.

In the case of the present embodiment, when the area is designated as shown in FIG. 5, the third to fifth rows are the format setting area. Figure 5
The document is stored in the document data storage area as shown in FIG. The "↑" mark in FIG. 6 indicates that there is a line feed mark or line feed due to the limitation of the number of characters per line.

In FIG. 6, those enclosed in () indicate that they are actually coded and stored, and those enclosed in [] are designated as areas. Indicates that. However, the data indicating that the area is designated is not stored in the document data, and the address is stored in another area designated position storage memory (RS, RE). In the case of this figure, the area designation start address RS = 27 and the area designation end address RE = 50.

Further, as shown in FIG. 5, since this area is not specified at the beginning of the line, the formatting start address SS and the formatting end address SE are SS = 25, S.
It is corrected to the beginning of the line such as E = 55.

The format setting process of this embodiment is divided into the following three types depending on the area designation method.

If the start position and end position are not designated (note that this is exactly the same as the format setting of the prior art, and for convenience of explanation, FIG. 22 (a) (b) is used again. 22 (a) and 22 (b) illustrate the range of the format setting in this case. In the figure (a), after the cursor C,
When the format is changed in the middle of the document, the format setting area in this case is from the line where the cursor C is located to immediately before the line where the format is changed next. FIG. 10B shows the case where the format has not been changed from the cursor C to the end, and the format setting area in this case is from the line where the cursor C is to the end of the document.

7A and 7B show the range affected by the format setting in this case. In the figure (a), after the start position is specified,
In the case where the format is changed in the middle of the document, the formatting area in this case is from the line where the start position is specified to immediately before the line where the format is changed next. FIG. 10B shows the case where the format has not been changed from the start position designation to the end. In this case, the formatting area is from the line where the start position is designated to the end of the document.

When both the start position and the end position are designated FIGS. 8A and 8B show the range affected by the format setting in this case. In the figure (a), after the start position is specified,
This is the case where the format has been changed in the middle up to the designation of the end position, and the case (b) in the figure is the case where it has not been changed. In both cases, the format setting area is the same.

The processing when both the start position and the end position are designated is divided into the following three (1) to (3).

(1) When the format is changed on the line next to the end position FIGS. 9A and 9B show the state of (1), and the area is changed as shown in FIG. If specified, it will be as shown in FIG.

(2) When the format is not changed in the line next to the end position and the format is changed in the designated area FIGS. 10 (a) and 10 (b) show the state of (2). If the format has been changed in the specified area as shown in Fig. 6 (a), after formatting, the format set last in the specified area as shown in Fig. 6 (b) (in this example) Format 3) is set on the line following the end position.

(3) When the format is not changed in the line next to the end position and the format is not changed even in the designated area FIGS. 11A and 11B show the state of (3). When an area is designated as shown in FIG. 9A, the format (format 2 in this example) set last before the start position is next to the end position as shown in FIG. Is set in the line.

Next, description will be made regarding the processing in the case where a line head input prohibited line due to indentation is included in the setting area designated by the above format setting.

FIG. 12 shows an example of a document with indentation. The mark B represents an indentation start mark, and the mark D represents an indentation cancellation mark. The indentation removal mark also has the function of a line feed mark.

In this embodiment, a "start indent" key and a "unindent" key (not shown) are provided on the keyboard 6, and the user moves the cursor to an arbitrary position in the document displayed on the display screen, When those keys are input, an indentation start mark and an indentation cancellation mark are inserted at the cursor position.

When the indentation start and the indentation removal are input, the line from the line following the indentation line to the indentation removal line, from the beginning of the line to the column where the indentation is started becomes the input prohibited area, and the document is displayed with the characters filled. It As shown in FIG. 12, when indentation is performed at the second digit,
1 to 2 until the indent removal mark appears from the next line
The digit is the input prohibited area.

A dedicated code is assigned to each of the indentation start mark and the indentation removal mark, and the code is inserted in the address of the mark position in the document data. When indentation is performed as shown in FIG. 12, in the present embodiment, the area designation start position is on the 3rd to 7th lines, or the area designation end position is 3 to 7.
If it is on the 6th line, formatting cannot be done and an error occurs.

Next, the processing process of the format setting mode in the above specified area will be described below.

The format setting mode in the designated area starts to be executed when a "format setting" key (not shown) provided on the keyboard 6 is pressed. First, as shown in the flow chart of FIG. The secured necessary variable area is initialized to 0 (S1), and then it is determined from the value of the area designation start address RS whether or not the start position of the area is designated (S2). In S2, when the start position area is specified, that is, when RS ≠ 0, the process directly proceeds to S4 described later, while when the start position area is not specified, that is, RS = If it is 0, the address of the current cursor position is stored in RS (S3), and the process proceeds to S4.

In S4, the format start address SS is obtained from the area designation start address RS, and the process proceeds to S5.
The processing in S4 is a countermeasure for the case where the area is designated in the line because the format data can be inserted only at the beginning of the line in this embodiment. The detailed processing contents in S4 will be described later with reference to the flowchart of FIG.

In S5, it is determined whether or not the end position of the area is designated from the value of the area designation end address RE. If the area of the end position is not designated in S5, that is, if RE = 0, the process proceeds to S12 described later, while if the area of the end position is designated, that is, RE ≠ 0. In this case, the formatting end address SE is obtained from the area designation end address RE (S6), and then the process proceeds to S7. Note that the processing in S6 is, similarly to the processing in S4, a countermeasure for the case where an area is being designated, and the detailed processing contents will be described later with reference to the flowchart of FIG. Is.

In step S7, it is determined from the contents of D (SE) (contents of address SE in the document data) whether or not the format is changed in the first line after the end of the designated area.
If the format is changed in S7, that is, D (SE)
In the case of = format code, the process proceeds to S8, all the format data in the format setting range (SS to SE-1) is erased, and then the process proceeds to S12 described later. In S8, the portion containing the format data is to be filled with the subsequent data.

On the other hand, if the format is not changed in S7, that is, if D (SE) ≠ format code, the process proceeds to S9, and whether or not the format is changed within the format setting range, That is, it is determined whether or not the format code exists in the document data within the format setting range (SS to SE-1). In S9,
If a format code exists, the formatting range (SS-S
In E-1), the last set format (the format data that is found first by going up from SE backward) is set to D (SE)
(S10), and then the above-described S8 is performed.
On the other hand, if the format code does not exist in S9,
The format that was set last before the format start position (the format data that was found first by going up from SS backward) is set to D
It is inserted into (SE) (S11), and then the process proceeds to S12.

In S12, the new format is input from the keyboard 6 in response to the user's key operation, and then the new format data is inserted into D (SS) (S13), and the processing process in the above format setting mode is performed. To finish.

Next, the process of determining the format setting start address in S4 and the process of determining the format setting end address in S6 will be described below with reference to the flowcharts of FIGS. 14 and 15. It should be noted that the format setting information is always inserted at the beginning of the line, but when the user specifies the area, it is not always specified at the beginning of the line. Therefore, when the area is designated in the line, the method of obtaining the address at the beginning of the line is each of the above-mentioned confirmation processes.

The process of determining the format start address is
As shown in FIG. 14, first, the variable shown in FIG. 4 is initialized to 0 (S21), and the value of the variable RS is assigned to the pointer P (S22). In the above S22, the variable RS
Stores the start address of the area specified by the user.

Next, the value of the pointer P is decremented by 1 (S2
3) Then, it is determined whether or not the value of D (P) (data designated by the pointer P in the document data) matches the format code (value indicating the start of the format data) (S24).
If the value of D (P) does not match the format code in S24, the process returns to S23 again, while if the value of D (P) matches the format code, the value of pointer P is incremented by 2 and D
Read the value of (P) (“number of characters per line”) and use this as the variable X
Substitute for 1 (S25). After that, the value of the pointer P is incremented by 1 so as to indicate the last address of the format data (S
26) and the process proceeds to S27.

In S27, the value of the variable X2 is initialized to 0, and then the values of the variable X2 and the pointer P are incremented by 1 (S28), and the process proceeds to S29. In S29, the value of the pointer P and the value of the variable RS are compared to determine whether they match. In S29, when the value of the pointer P and the variable RS match, that is, when there is a pointer at the area designation start address, the process proceeds to S38 described later, while the value of the pointer P and the variable RS do not match. Is
In S30, it is determined whether the value of D (P) is a value indicating an indent character. In S30, when the value of D (P) is not a value indicating an indent character, the process directly proceeds to S32 described later, while when the value of D (P) is a value indicating an indent character, the variable I is set to 1 To the variable IX
2 is substituted (S31), and then the process proceeds to S32.

In S32, it is determined whether or not the value of D (P) is a value indicating an indent cancellation character. In S32, D
When the value of (P) is a value indicating the indentation removal character, 0 is assigned to the variable I and X3 is assigned to the variable X1 (S33), and the process returns to S27 again. On the other hand, if the value of D (P) is not a value indicating the indentation removal character, the process proceeds to S34, and it is determined whether the value of D (P) is a value indicating a line feed.

When the value of D (P) is not a value indicating a line feed in S34, the process proceeds to S35 and the value of the variable X2 is changed to the variable X.
It is determined whether or not it matches the value of 1. If they do not match,
Again, while returning to S28, if they match, S34
Then, as in the case where the value of D (P) is a value indicating a line break,
The process moves to S36. In S36, it is determined whether or not the value of the variable I is 1, and when the value of the variable I is not 1, directly,
While returning to S27, when the value of the variable I is 1,
In S37, the variable I is set to 2 and the variable X3 is set to the value of the variable X1.
Further, a value obtained by subtracting the variable IX from the variable X1 is assigned to the variable X1, and then the process returns to S27.

If the value of the pointer P and the variable RS coincide with each other in S29, it is judged in S38 whether or not the value of the variable I is 2, and if the value of the variable I is 2. Shifts to S39, performs error processing such as displaying a message, and ends the process. On the other hand, S38
Then, if the value of the variable I is not 2, the process proceeds to S40,
The variable X2 is subtracted from the variable P, the value obtained by adding 1 is substituted for the variable SS, and the above-described process of determining the format start address is completed.

It should be noted that the processing speed can be increased by storing the line feed character position, the indent setting, etc. during the processing of S23 to S24, but this is omitted for simplification of the description. Also, when indentation is set,
Since the number of characters per line apparently decreases, the variable X1 is set in S37.
Is decreasing the value of. Many word processors have half-width characters and tab setting functions, but in this case as well, the present start address determination method can be applied by adjusting the number of pointer movements.

In this embodiment, when the line head is in the input prohibited area (indentation is set), the format cannot be set, and therefore the error processing is performed in S39. However, since the start line of the indent setting start line is not the input prohibited area, an error does not occur and formatting can be performed. As for the value of the variable I, 0 means a line in which no indent is set, 1 means an indent setting start line, and 2 means an indent setting line (the beginning of the line is an input prohibited area).

Next, the process of determining the format end address will be described below with reference to the flowchart of FIG. Note that this confirmation process is a method of obtaining the address at the beginning of the line (of the next line) when the end position area is designated in the line.

First, the variable shown in FIG. 4 is initialized to 0 (S41), and the value of the variable SS-1 is substituted for the pointer variable P (S42). In step S41, the variable SS and the variable X1 whose values are obtained in the formatting start address determination process performed before this process are not initialized. Further, in S42, the variable SS stores the formatting start address.

Next, the variable X2 is initialized to 0 (S4
3) After that, the values of the variable X2 and the pointer P are incremented by 1 (S44), and the process proceeds to S45. In S45, it is determined whether or not the value of the pointer P and the value of the variable RE match.
If the value of the pointer P and the value of the variable RE do not match in S45, that is, if there is no pointer at the area designation end address, the process directly moves to S47, while the value of the pointer P and the value of the variable RE are equal to each other. If they match, that is, if there is a pointer at the area designation end address, 1 is assigned to the variable F (S46), and then the process proceeds to S47.

In S47, it is determined whether or not the value of D (P) is a value indicating an indent character. If the value of D (P) is not a value indicating an indent character, the process directly proceeds to S49. , D (P) is a value indicating an indent character, 1 is assigned to the variable I and X2 is assigned to the variable IX (S48), and then the process proceeds to S49.

In S49, it is determined whether or not the value of D (P) is a value indicating an indentation cancellation character. If the value of D (P) is a value indicating an indentation cancellation character, the variable I is set to 0.
By substituting X3 into the variable X1 (S50), and thereafter shifts to S55 described later. On the other hand, in S49, D
If the value of (P) is not a value indicating the indentation removal character, the process proceeds to S51, and it is determined whether or not the value of the variable X2 matches the value of the variable X1.

In S51, when the value of the variable X2 matches the value of the variable X1, the process proceeds to S53 described later, while when the value of the variable X2 does not match the value of the variable X1, the process proceeds to S52. It is determined whether the value of D (P) is a value indicating a line feed. If the value of D (P) is not a value indicating a line feed in S52, the process returns to S44 again, while if the value of D (P) is a value indicating a line feed, the process proceeds to S53.

In S53, it is determined whether or not the value of the variable I is 1, and when the value of the variable I is not 1, the process directly proceeds to S55 described later, while the value of the variable I is 1 Is 2 for variable I, the value of variable X1 for variable X3, and
A value obtained by subtracting the variable IX from the variable X1 is substituted for the variable X1 (S54), and then the process proceeds to S55.

In S55, it is determined whether or not the value of the variable F is 1, and when the value of the variable F is not 1, the process returns to S43 again, while when the value of the variable F is 1. , S5
Moving to 6, it is determined whether the value of the variable I is 1 or 2.

When the value of the variable I is either 1 or 2 in S56, the process proceeds to S57 and an error process such as displaying a message is performed and the process is terminated. On the other hand, if the value of the variable I is neither 1 nor 2 in S56, the process proceeds to S58, where the variable SE is replaced by the variable P.
Substitute the value of +1 (the value of this variable SE is the end address of the desired format setting (the beginning of the line following the end position area specification))
Is. ), And the process of determining the end address for formatting as described above ends.

The above-mentioned format setting start address determination and format setting end address determination can be performed collectively because they are similar in processing, but since the processing becomes complicated, in this embodiment, there are two. It is divided into Further, in this embodiment,
If the beginning of the line is the input prohibited area (the indent is set), the format cannot be set.
Error handling is done in.

When the formatting start address is confirmed, the indent start line can be formatted and an error does not occur. However, when the formatting end address is confirmed, a new format is set on the line next to the end line. Since it must be, an error occurs. On the other hand, in the indent release line, the start address cannot be fixed, but an error does not occur if the end address is fixed. As for the value of the variable I, 0 means a line in which no indent is set, 1 means an indent setting start line, and 2 means an indent setting line (the beginning of the line is an input prohibited area).

Next, the designated format search processing, designated format replacement processing, and designated format unification processing in this Japanese word processor will be described below. In the following description, as shown in FIG. 16, it is assumed that the current state of the format of the cursor position is stored in the RAM 2, and when the cursor moves on the display screen, the format code is included in the document data. If so, the format information in FIG. 16 is also updated to a new one, and the current format can always be known. (When the cursor moves to the front of the format code, the format information of the previous one is stored.)
First, the search process of the designated format will be described. In this embodiment, there are two types of search methods for format search. One is
This is a method of specifying the format to be searched and inputting its value.
This searches for the setting position of the specified format that matches the input value of the specified format. For example, "line feed pitch / 5
If "mm" is specified, the position where the line feed pitch is set to 5 mm is searched after the cursor.

The other is a method in which only the item of the format to be searched is specified and its value is not input. This searches for the position where the specified format was first changed after the cursor. What is different from the conventional technique is that even if a specified format item is changed, if the specified format item is not changed, it is not a search target. For example, if "line feed pitch" is specified, the position where the line feed pitch is first changed after the cursor is searched for.

In the following description, a method for searching the designated format after the cursor will be described. However, searching before the cursor, designating a processing area, and simultaneously searching for a plurality of types of format items may be performed to some extent. Can be changed.

Next, the processing process of the search mode of the above designated format will be described below.

The search mode of the designated format is started when a "format search" key (not shown) provided on the keyboard 6 is pressed. First, it is secured in the RAM 2 as shown in the flowchart of FIG. The necessary variable area is initialized to 0 (S61). Then, a menu as shown in FIG. 18A is displayed on the display screen, and when the user selects one of the formats to be searched by the keyboard 6, the selected format is stored in the RAM 2 (S62), Selection of whether to specify the value of the search format is similarly determined from the menu as shown in FIG. 18B (S63). In the present embodiment, the case where "the number of pointers" is selected in S62 and "there is a value designation" in S63 is illustrated.

If the search format value is not specified in S63, the process directly proceeds to S65, while if the search format value is specified, the user operates the keyboard 6 from the menu as shown in FIG. Enter the value of the search format (S6
4) After that, it transfers to S65. In addition, S6 shown below
Each step after 5 is an actual search routine.

At S65, the value of the pointer P is incremented by 1.
After that, it is determined whether or not the pointer P indicates the end of the document (S66). If the pointer P indicates the end of the document, the processing process is terminated while the pointer P indicates the end of the document. If not instructed, the process proceeds to S67. In S66, the end code is stored at the end of the document.

In S67, it is determined whether or not D (P) (contents of the document data pointed by the pointer P) is a format code. If D (P) is not a format code, the process proceeds to S65 again. On the other hand, when D (P) is the format code, the process proceeds to S68, and it is determined whether or not a value is input and designated. In S68, if the value has not been input and designated, the process proceeds to S69, and the value of the designated format of the current format and the value of the designated format of the retrieved format are compared and determined. S69
If the value of the specified format of the current format and the value of the specified format of the retrieved format are equal, the process returns to S65 again, while the value of the specified format of the current format and the value of the retrieved specified format If and are not equal, the process proceeds to S71 described later.

On the other hand, if a value is input and specified in S68, the value input in S64 is compared with the value of the specified format of the searched format data (S70). S
If the input value is not equal to the specified format value of the retrieved format data in 70, the process returns to S65 again, while the input value is equal to the specified format value of the retrieved format data. Moves the cursor to the character data immediately after the searched format data, displays it on the display screen (S71), and ends the processing process in the search mode as described above. By repeating the steps S65 to S70 as described above, the target position is searched.

Next, the processing process of the designated format replacement mode will be described below. In this embodiment, a method of collectively replacing all designated formats after the cursor will be described.
It is possible to make a slight change to the target before the cursor, to ask if you want to replace sequentially when replacing, to specify the processing area, to replace multiple types of format items at the same time, etc. It is possible.

The substitution mode of the designated format is started when the "format substitution" key (not shown) provided on the keyboard 6 is pressed. First, it is secured on the RAM 2 as shown in the flowchart of FIG. The necessary variable area is initialized to 0 (S81). Then, a menu as shown in FIG. 20A is displayed on the display screen, and when the user selects any one of the formats to be replaced by the keyboard 6, the selected format is stored in the RAM 2 (S82). . Then, when the user inputs the value of the replacement format (before replacement) from the menu as shown in FIG. 20B (S83) and also inputs the value of the replacement format (after replacement) (S84), thereafter. , S85. Incidentally, each step after S85 shown below is an actual replacement routine.

At S85, the value of the pointer P is incremented by 1.
Then, it is determined whether or not the pointer P indicates the end of the document (S86). If the pointer P indicates the end of the document, the processing process is terminated while the pointer P indicates the end of the document. If not instructed, the process proceeds to S87. In S86, the end code is stored at the end of the document.

In S87, it is determined whether D (P) (contents of the document data pointed by the pointer P) is a format code. If D (P) is not a format code, the process proceeds to S85 again. On the other hand, when D (P) is a format code, the process proceeds to S88, and the value input in S83 (before replacement) and the value of the specified format of the retrieved format data are compared and determined. In S88, if the input value and the value of the specified format of the retrieved format data are not equal, the process directly returns to S85 while the value of the input format is equal to the value of the specified format of the retrieved format data. Replaces the value of the specified format of the retrieved format data with the value (after replacement) input in S84 (S89), and returns to S85 again. Then, the values of the designated format are replaced by repeating the above steps S85 to S89 until the end of the document.

Next, the processing process in the unified mode of the designated format will be described below. In addition, in the following description, a method of unifying all the designated formats after the cursor at once will be explained.
A method such as asking whether to unify, designating a processing area, unifying a plurality of types of format items at the same time, or the like can be performed with some changes.

The designated format unifying mode is started when the "unify format" key (not shown) provided on the keyboard 6 is pressed. First, it is secured in the RAM 2 as shown in the flowchart of FIG. The necessary variable area is initialized to 0 (S91). Then, the menu is displayed on the display screen, and when the user selects one of the formats to be unified by the keyboard 6, the selected format is RAM2.
It is stored above (S92). Then, it transfers to S93.
Incidentally, each step after S93 shown below is an actual unified routine.

At S93, the value of the pointer P is incremented by 1,
Next, it is determined whether or not the pointer P indicates the end of the document (S94). In S94, when the pointer P indicates the end of the document, the processing process is ended, while when the pointer P does not indicate the end of the document,
The process moves to S95. In S94, the end code is stored at the end of the document.

In S95, it is determined whether or not D (P) (contents of the document data pointed by the pointer P) is a format code. If D (P) is not a format code, the process proceeds to S93 again. On the other hand, if D (P) is the format code, the process proceeds to S96 to unify the value of the designated format of the retrieved format data with the value of the current format, and then returns to S93. Then, the steps of S93 to S96 as described above are repeated until the end of the document to unify the values of the designated format.
