Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a document creation device, and more specifically, to a document creation device and a device for creating and editing documents by mixing different types of data such as text, graphs, figures, etc. This invention relates to an improvement of a document creation device.

[Conventional technology]

In recent years, in document creation devices such as word processors,
The type of data handled is not only text (character) data, but also figures, graphs, and tables.

There are more and more types as shown in the image.

In addition, the above-mentioned method for creating a document in which a plurality of pieces of data are mixed is described in, for example, Japanese Unexamined Patent Application Publication No. 18036/1981, and according to the document creation device described in the same publication, one created document can be created. After specifying the area where the data to be edited is stored on the page layout, the detailed information for that area is displayed and edited in a separate area from the page layout. According to this method, when modifying data in one document, there is an advantage that the operator does not have to be aware of the application program that is most suitable for handling the data to be modified.

[Problem that the invention seeks to solve]

However, in the above-mentioned conventional technology, an operator edits a region while editing another region, or edits a region on a page different from the page where the region exists. We are not aware of the need to refer to the layout, so if you need to perform the operations described above, you should either finish editing the area you are currently creating or edit the area you are currently creating. After printing the document, you must refer to it and edit the corresponding area again.

Therefore, when creating a document containing a mixture of multiple data as described above, it is necessary to create various data.

There is no need to finish editing, editing areas on the layout display, switching display parts, etc.

If you switch to another editing operation, the operability will be improved compared to the previously proposed document creation device, but if you simply switch the editing department that is currently in the middle of editing to another editing department, Thereafter, when the editing section (which is in the middle of editing) resumes the editing work, there is a problem that the page layout of one document cannot correspond to the display content of the data that is in the middle of editing.

The present invention has been made in consideration of the above points, and includes:
The purpose of this is to switch to another editing department during editing in one editing department, and then promptly redisplay the original page layout before restarting editing in the original editing department. Therefore, the operator can immediately recognize the page layout in the middle of one edit. The present invention aims to provide an improved document creation device with excellent operability.

[Means for solving problems]

The purpose is to provide an input unit for inputting description elements to be described in one document for each area for documents in which multiple types of description elements are mixed, and a storage unit for storing description elements input to the input unit. a display section that displays various descriptive elements stored in the storage means; an area editing section that creates and edits data in each area; and a page layout of the document to be created on the display section; An editing unit comprising a document creation device comprising: a document editing unit that edits an area and activates an area editing unit for an area that is instructed to be created or updated; and an editing unit switching unit that switches editing by each of the editing units. The editing department switching means includes a switching notification means for notifying the resuming editing department when a switching operation is performed to another editing department and then a switching operation is performed to the original editing department during the execution of editing. and a startup area editing department management means for managing which area in one document is currently being edited; This is achieved by providing the document editing section with a layout redisplay means that determines whether or not there is an area in the middle of editing in the page layout, and redisplays the layout if the corresponding area exists. be done.

[Effect]

In the above configuration, when a switching operation is performed to another editing section during execution of editing in the editing section, and then switching to the original editing section, the restarting editing section is notified of this fact.

Further, which area in the document is currently being edited is managed by the startup area editing department management means.

Further, the layout re-display means is configured to display an area in the middle of editing in the original page layout based on the content managed by the startup area editing department management means when the restart editing section receives a restart notification. It is determined whether the corresponding area exists, and if the corresponding area exists, the layout is redisplayed.

B is connected and managed in a list prepared for each cause based on the cause of each wait, and when the wait is released due to the occurrence of the above event, the TCB is removed from the corresponding list and the REA
The DY queue 533 is connected, and the task is resumed from the interrupted position by the task dispatcher.

Messages are managed by a message control table 534, as shown in FIG. 10, and the message control table 534 is managed by a message control block 535 (hereinafter referred to as
(abbreviated as MCB), and one MCB 535 is assigned to one message.

The MCB 535 includes, for example, a status 5351. Sender task number 5352. Receiving side task number 5353. A message size 5354 and a message buffer 5355 for temporarily holding the transmitted message are stored.

Also, if a message reception request is made according to the message reception request parameters, but the message has not yet been sent from the other task.

REA the TCB532 corresponding to the task that requested reception.
It is also possible to remove the task from the DY queue 533 and connect it to the message reception queue 536 shown in FIG. 11 to place the task in the WAITING state until the message is sent, or to place the task that requested reception in the 11AITING state. Instead, you can simply tell the task that the message has not been sent.

Here, the overall processing flow of the system control unit indicated by reference numeral 53 in FIG. 1 will be explained based on FIG. 12. When a processing request is issued from a task to the stem control unit 53,
First, the execution environment at the time when the task issued the request is TCB.
532 (step 1001 in FIG. 12),
Next, the requested functions (steps 1003 to 1008) are identified and processes corresponding to each function are activated (step 10
02).

After the processing corresponding to each function is completed, it is determined whether the task will be switched or not based on the state of the READY queue 533, for example (step 1011). If the task is switched, the task dispatcher 1013 is activated. If the task is not switched, the execution environment saved in step 1001 is restored from the TC 8532 (step 1012), and the task that issued the request is restarted. Furthermore, when an input/output end interrupt occurs from the input/output device, the execution environment at the time when one interrupt occurs is saved in the TCB 532 (step 1009). Next, after performing input/output termination processing such as passing the input character code etc. to the input request task and releasing the input task from waiting (step 1010).

Activate the task dispatcher 1013.

As shown in FIG. 12(j), the task dispatcher 1013 sends the TCB5 to the READY queue 533 in FIG.
Step 119 to determine whether or not 32 is connected.
1) If the TCB 532 is not connected to the READY queue 533, an infinite loop '#=4 (step 1197) is performed until an interrupt occurs, and the READY queue 532 is connected to the READY queue 533.
If CB532 is connected to 33, READ
The TCB 532 with the highest priority is acquired from the pointer stored in the header of the Y queue 533, and based on the suspension flag information (reference numeral 5325 in FIG. 8) of the TCB, it is determined whether there is a suspension request for the task. (Step 1
192).

Then, if there is a suspension request for the task, the pointer is updated and the relevant TCB 532 is removed from the READY queue 533 (step 1193), and the process is performed again from step 1191.
Step 1194: Set CB532 to ACTIVE state.

, and generate the program as a task.
In order to start the generated task, the system control unit 53 is requested to generate and start the task.

In addition, in step 1306 of FIG. 13, if there is an instruction for an operation target within the topmost window, the indicated coordinate values are converted from coordinates on one screen to relative coordinate values within the window (step 1306). 1317), and passes the coordinate value to the task that requested the input (step 1318).
).

In step 1307, if the operator's instruction is the menu area 22 in FIG.
is requested to open the pull-down menu area 28 (step 1315).

Further, in step 13o7, if the operator's instruction is the pull-down menu area 28 (step 13
08), determine which function item has been specified, and pass the specified function item number and pull-down menu number to the task that requested the input (step 1319).

In step 1309, the operator's instructions are in the control area 253 or caption area 2 in the window.
If it is 51, the code for closing, scrolling, etc. is passed to the task that requested the input (step 1310).

Further, in step 1309, the operator selects the control area 253 or caption area 2 within the window.
If an area other than 51 is specified, nothing is executed.

Note that when passing a code to an input requesting task, the system control unit 53 in FIG.
Transition from ING state to READY state.

The menu is stored in the menu management table 523. shown in FIG. It is managed by a pull-down menu management table 525.

In FIG. 14, the menu management table 523 includes:
Number of pull-down menus: 5231. The subsequent menu management block 524 is stored in the order of the pull-down menu numbers by the number of pull-down menus. The menu management block 524 includes a pull-down menu name 524.
1. Maximum number of characters for function item: 5242. Number of function items: 524
3. A pointer 5244 to the pull-down menu management table 525 is stored.

In addition, the pull-down menu management table 525 includes one function item name 5251. Valid/invalid flags 5252 indicating whether a function item is valid or not are stored in the order of function item number for the number of function items.

Based on the above information, the input control unit 51 in FIG. Menu area 22 in the figure
to be displayed. Also.

When a pull-down name is specified with the mouse 31 in FIG. 3, the function item name is acquired from the corresponding pull-down menu management table 525 in FIG. 14, and if the function item is valid, it is normally displayed.

If it is invalid, it is displayed in half-brightness in the pull-down menu area 28 of FIG. 2.

In FIG. 1, a print control section 54 controls the printing section 4 based on a document printing request from an editing section 56. As shown in FIG. Also,
In response to a display request from the first editing section 56 and the window management section 52, the display control section 55 displays data for only the portion that can be developed in the topmost window based on the stacking order information of the window management block 522 shown in FIG. is written to the corresponding memory dot by dot.

Here, the case where the Japanese word processor shown in this embodiment is used to create and edit a document will be described below.

First, in the initial state, in order to start creating a new document or editing an already created document, the operator points to the corresponding icon using the mouse 31 in FIG.

In response to the instruction from the operator, the input control section 51 in FIG. 1 determines which icon is specified based on the screen instruction coordinates, and notifies the system management section 57 of the icon number. On the other hand, as shown in the flowchart of FIG. 18, after displaying the icon in the initial state (step 1701), the system management unit 57 requests the reception of a message and requests step 1 to receive the message.
702), if a message is received in step 1702, the sender of the message is determined in step 17.
03).

If the sender of the message is the input control unit 51, the first step is to obtain the program number corresponding to the designated icon based on the icon management table 571 in FIG. 4 (step 1704), and edit the corresponding The section is generated as a task and activated (step 1705).

To generate and start the task described above, as shown in the processing flow of FIGS. 12(a) and 12(c), the system management unit 57 first requests the system control unit 53 to generate a task based on the program number. When this is done, the system control unit 53
Based on this, obtains an unused task number from the task control table 531 in FIG.
B532 (step 110 in FIG. 12(a))
1) Put the task in DORMANT state Step 11
02), the acquired task number is returned to the request source (step 1103).

Next, when the system management unit 57 issues a task activation request according to the task number, the system control unit 53
REA the TCB532 corresponding to the specified task number
Step 1121) in FIG. 12(c) as DY state,
By connecting this TCB 532 to the READY queue 533 in FIG.

The relevant editorial department becomes executable (step 11)
22).

Note that the notification of the icon number described above is performed by sending and receiving messages via the system control unit 53. For example, as described above, from the input control unit 51 to the system management unit 5
7, the input control unit 51 first requests the system control unit 53 to send a message to the system management unit 57 (step 1706 in FIG. 18).

Then, as shown in FIG. 12(h), the system control unit 53 determines from the message control table whether or not a reception request from the system management unit 57 has arrived.
Step 1171 in Figure 2 (h)).

If a reception request has arrived, the message to be sent is transferred to the message buffer (also numbered 5355 in FIG. 10) of the corresponding MCB (reference number 535 in FIG. 10) (step 1174), and the reception waiting task, that is, the system management The TCB of section 57 (numeral 532 in Fig. 8) is
It is removed from the message reception queue 536 in the figure and connected to the READY queue 533 in FIG. 9 (step 1175 in FIG. 12(h)).

Further, in step 1171 of FIG. 12(h), if there is no reception request yet, the system control unit 53 acquires an unused MCB (step 1172), and transfers the message to the message buffer of this MCB (step 1173). ).

On the other hand, when the system management section 57 requests the system control section 53 to receive a message, as shown in FIG.
As shown in FIG. 12, the system control section 53 determines whether or not the message for the system management section 57 is in the MCB (step 1181 in FIG. 12(i)). For example, the message is retrieved from the MCB and transferred to the system management unit 57 that is the request source (step 1184).

Note that if there is no message on the MCH in step 1181, it is determined whether the task that issued the macro made the request with waiting specified (step 1182).
, if there is no waiting, returns that there is no message for the task and ends the process (step 1185).
.

In addition, in step 1182, if there is a wait,
After acquiring the unused MCB, the TCB of the task is removed from the READY queue 533 in FIG. 9 and connected to the message reception queue 536 in FIG. 11 (step 1183).
, transfers control to the dispatcher (step 1186).

Namely.

When a message is transferred to the MCB in response to a message transmission request, the task that was waiting for reception is connected to the READY queue 533, so this task is restarted.
The message receiving process is executed again, and the contents of the MCB (message) are received by the task.

If the operator's instruction is to create a new document, the text f editing section indicated by reference numeral 561 in FIG. It is activated by the stem management section 57.

Next, the processing contents of the file editing section 58 will be explained based on the flow shown in FIG. 19.

In FIG. 19, the file editing section 58 first opens a window (step 2001 in FIG. 19), and displays a list of documents stored in the storage section 3 in the window (step 2002). After displaying the document list described above, the file editing section 58 requests input from the input control section 51 (step 2003), and if there is input, determines the contents. In step 2004.

If the input from the operator is an instruction for a document to be operated, it is determined which document has been instructed (step 2004), and the operation target document table 58 shown in FIG.
1 (step 2005). Note that the operation target document table 581 shown in FIG.

Step 2006): Notify the ring unit 57 that the instruction to update and print has been given, along with the name of the currently targeted document and the data type number corresponding to the document.
, in the case of an editing instruction such as copying or deleting a document, processing such as copying or deleting the specified document is performed (step 2007).

If it is a scroll instruction, a scroll display of the document name list is performed (step 2008); if it is an end instruction, the window is closed (step 2009);
Notify the system management unit 57 that the file editing process has been completed (step 2010), and request the task to end (step 2011). Along with this end request,
As shown in FIG. 12(d), the system control unit 53
The TCB of the requesting task (see reference numeral 532 in Figure 8) is D.
Step 11 in FIG. 12(d) to set the ORMANT state.
31) Release the resources used by the task (step 1132), where resources refer to memory and CPU.

Further, the window opening/closing process is performed in the window management unit 52 shown in FIG. 1, and the contents of the process will be explained based on the flowcharts shown in FIGS. 15 and 16.

First, in the case of window opening, window management section 5
2 generates the VCB 522 shown in FIG. 7 based on the information specified by the task (step 15 in FIG. 15).
01), and at that time, it is determined whether the window already exists or not (step 1502), and if it does exist, the task that is currently using the topmost window is temporarily interrupted (step 1503). , the display image of the topmost window is saved in the display buffer (step 1504).

Then, the window is displayed according to the position and size specified by the task (step 1505), and the number of the generated window management block is returned to the requesting task (step 1506).

On the other hand, in the case of window closing, the image of the specified window is first erased (step 1511 in FIG. 16), and then the window management table 52 in FIG.
1, the window hidden by the window to be closed is identified, the display image is retrieved from the display buffer described above, and the display image of the window below the erased window is restored.Step 1512
).

The VCB 522 of the erase window is made unused (step 1513), and the task interruption process will be described later.

Therefore, when the request from the operator is to create a new document, the system management section 57 generates the document editing section 561 as a task based on the notification from the input control section 51 (step 1705 in FIG. 18), and then creates a new document. Start up in creation mode (step 1707).

In addition, if the request from the operator is to update an already created document, the corresponding program number should be obtained from the program control table (numeral 572 in FIG. 5) based on the data type number notified from the file editing section 58. Step 1
708), document editing section (step 1710), and starting the document editing section 561 in update mode (step 1711)
.

Furthermore, when the system management section 57 receives a completion notification from the editing section that it generated and activated, it deletes the task (step 1712 in FIG. 18).

The deletion of a task is processed by the system control unit 53 in the same way as the task generation request described above, and the system control unit 53 deletes the TCB (No. (see reference numeral 532 in Figure 8) to N
0NIEXISTENT state (step 1111 in FIG. 12(b)). In other words, the TCB is placed in an unused state.

Incidentally, when the system management section 57 starts up the one-document editing section 561, it sends the mode and the generated task number as a starting parameter to the document editing section 561 by a message. In addition, in the case of document update mode, the name of the document to be updated notified from the file editing section 58 is also transmitted.

Now, the processing when the text is eastern part 561 is activated will be explained based on the flowcharts of FIG. 21 and FIGS. 22(a) to (Q).

First, as an initial process (step 3001 in FIG. 21), the sentence iF editing unit 561 receives startup parameters via message (step 3101 in FIG. 22(a)), and creates a new document based on the contents of the parameters. Determine whether there is a document update, and the startup mode (step ato
2). and.

When creating a new document, initialize the document data (
Step 3103), in the case of document update (step 3104), and the structure of one document data will be described later. Then, the program control table (reference numeral 5 in FIG.
72), a support area editing department management table (hereinafter abbreviated as SFMT) is created which shows a list of area editing departments that can newly create and update areas in one document. As shown in FIG. 27, the SFMT stores a program number 5682 of an area editing unit that can be supported and a data type editing unit 5683 that can be created by this area editing unit as a pair, and further stores a number of area editing copies 5681. Having, also.

At the same time, the name of the data for the area editing section is set in the pull-down menu data in order to inform the operator of what kind of data it is currently possible to create an area for (step 310 in FIG. 22(a)).
5), and thereafter, when editing an area to be described later, the designated area of the operation target area table (FIG. 28) indicating which area is the operation target is cleared to 0 (step 3106).

Next, the valid/invalid state of the pull-down menu data is initialized (step 3107).As shown in FIG. Type 5685 of the area specified as the target,
The number 5686 of the area designated as the operation target is held. Note that the type of area will be described later. Further, switching of pull-down menu data\enable/invalid will also be described later. Next, the document editing section 561 in FIG.
opens the window (step 3108 in FIG. 22(a)) and displays the layout of the first page of the edited document in the window as shown in FIG. 31(a) (step 3109). The size of this window is set to correspond to the size of the display paper, and the task number of the 1-document editing section 561 is added to a part of the window title.

Here, the SFMT shown in FIG. 27 and the menu data creation process shown in step 3105 in FIG. 22(a) will be explained in more detail.

The SFMT shown in FIG. 27 is the document editing section 561 of FIG.
For this, program number 56 of the area editing section that can be activated
This is a table showing a list of 82 and data type number 5683, and is used as a parameter when creating a new area, updating an area, and displaying a layout, which will be described later, to determine whether a corresponding program exists or not, and when creating a task. .

As shown in FIG. 22(b), the creation method is to first clear the program number P and registration number E (steps 3111 and 3112), and then sequentially clear the program number P and registration number E from the first block of the program control table (numeral 572 in FIG. 5). Then, it is determined whether the parent program number matches the program number of the document editing section (561 in FIG. 1) itself (step 3114).

If they match, the document editing section 561 considers it to be the PCB (reference numeral 573 in FIG. 5) for the area editing section that can be activated, and uses the program number P and the data type number island Dp set in the PCBS 73. is registered in the SFMT in FIG. 27 (step 3115), and the name of the data corresponding to the data type number (for example, "figure t+, it graph", etc.) is obtained from the DNDT (numeral 574 in FIG. 6). Then, the name is registered as the name of the pull-down menu data for creating a new area in the menu data (FIG. 23) held by the 1-document editing section 561 itself (Step 3116), and the registration number E is incremented (Step 3117). This process is repeated for the number of program management blocks (steps 3118 and 3113), and finally the registration number E is set to the number of area editing copies 5681 (step 3119). It is possible to display only the names related to the area editing department in a pull-down menu.

Next, the structure of document data will be explained using FIG. 24.

The document data is stored in the chapter 1 management table 5610. as shown in FIG. Page management table 5620. Page format table 5
630. The area management table 5640° is further composed of area data 5660, and each table is composed of a plurality of blocks. The respective tables (5610 to 5640) and the intra-area data 5660 will be explained below.

(Chapter management table 5610) Manages how many chapters the entire document consists of,
Page pointer 5611.5 indicating the first/last page for each chapter
612. It also holds print information 5613 for displaying and printing headers, footers, etc. for each chapter.

(Page management table 5620) Area pointers 5623, 5624 . Furthermore, a page format pointer 5 indicating which format data is used on page 6
625. Also, each block has a backward pointer 5
621 and the forward pointer 5622, the pages are linked in ascending order.

For the first/last page, refer to the chapter management table 5 mentioned above.
610 points. Note that the pages in this document data are structured as shown by reference numeral 5671 in FIG. 25. The page size and margins are determined in the page format table 5630 described below, and in the basic area 567.
2. Regarding the internal area 5673, area management table 5
640, respectively.

(Page format table 5630) The paper type (A

Manage top, bottom, left, right margins, etc.

(Area management table 5640) This table manages where and in what size data to be stored within a document (within a page), such as text data, graphic data, graph data, etc., is stored in a page. For this reason, the area management table 5640 has an area upper left corner xi 5643 . Same y coordinate 56
44° lower right X coordinate 5645. It has the same y coordinate of 5646,
Furthermore, data type 5647 indicating the type of data in the area
, an area attribute 5648 that indicates the attributes of the area itself, and a data pointer 5650 that points to data within the area 5660.
has. Note that the attributes of the area itself include whether it is transparent or opaque (in the case of opaqueness, the area covered by the area below becomes invisible), the line type of the area frame, etc. In addition, one table (area management table) 56
40, in order to manage the order in which regions within the same page overlap, a backward pointer 5641 and a forward pointer 5642 are used to link each other. Links in this area link from areas of low priority to areas of high priority, that is, from the lowest area to the highest area within the page. Also, among these,
The start/end areas are each pointed to from the page management table 5620 described above. Furthermore, the area management table 5640 includes status information 5649 indicating whether the area is being edited or not, and whether an area editing section corresponding to the area data type does not currently exist in the system.

On the other hand, the areas existing within the page indicated by the reference numeral 5671 in FIG. 25 can be roughly divided into the following two areas.

(i) Internal area 5673 This area exists on the basic area, and the position and size are determined by the operator's operation. Moreover, one of various data such as text, graphics, graphs, and images can be stored in the area.

Furthermore, editing this area involves creating a new area.

All area editing is possible, including updating, moving, copying, and deleting.

(it) Basic area 5672 Refers to the part of the page excluding the top, bottom, left, and right margins. When a page is generated by an operator's operation, one basic area is also generated. Within the page, it is always the first area (the lowest In addition, within one area, only text data such as the main text of the document is stored, and furthermore, when editing this area, it is possible to create a new area, update it, and move to this area.

For editing operations such as copying and deleting, move the page.

This is done through editing operations such as copying and deleting.

(Region data 5660) Data stored within an area, including text and shapes.

Graphs, image data, etc. are stored.

Now, in FIG. 21 showing the processing system of the document editing section indicated by reference numeral 561 in FIG. request (step 3002), and
Step 3003: Judging the input result from the operator
), if the determination result is an instruction for the area you want to operate.

Based on the document data, it is determined which area is specified based on the specified position within page number 2 and the setting position of the area, and the area number is registered in the operation target area table shown in FIG. 28 (step 3004). In addition, the determination method at this time is
This will be explained in more detail using the flow shown in FIG. 22(c).

In FIG. 22(C), first it is determined whether the designated position is in the basic area 5672 of FIG. 25 in step 3.
201), if the indicated position is outside the basic area 5672, there is no area corresponding to the indicated position, so it is determined as an instruction error.

In step 3201, the designated position is the basic area 567.
If it is within 2, the following internal area 5 within page 1 5671
Steps 3202 to 3205) determine whether or not the indicated position is within the internal area 5673, starting from the highest area (the last area within the page).
If the indicated position is within the internal area 5673, the operator's instruction is regarded as an operation instruction for the internal area 5673, and an instruction flag is placed in the internal area (step 3206).

On the other hand, if the indicated position is not within the internal area 5673 (
If the internal area designation flag is 0), it is assumed that the operator has designated the basic area 5672, and processing is performed. Now, if the indicated position is within the internal area 5673, next check whether or not the area 5673 has already been designated as a target, that is, whether the number of the area 5673 has already been registered in the operation target area table of FIG. If the area 5673 has already been designated as a target, the next area (on the document data, the forward pointer of the area management block of the area currently being determined) is 24) is checked (step 3211).

On the other hand, if the internal area 5673 has not yet been specified as a target, it is assumed that the area 5673 has been specified, and the number of the area 5673 is recorded in the operation target area table. Basic area 5672
is specified as the target (step 3208
).

Once the number of specified areas 5684 in the operation target area table is cleared to 0 (in other words, after the target designation for the basic area 5673 is canceled in step 3209), the internal area number and area type are registered in the operation target area table. , and further increments the number of designated areas 5681 by 1 (step 3210). In addition.

In the above, when the basic area 5672 is registered as an operation target, forcibly canceling the designation is as follows:
As described later, when the basic area 5672 and the internal area 5673 can be specified at the same time.

This is because there will be no area editing corresponding to this.

If the internal area 5673 is not registered in one or more processes, it is determined whether the internal area designation flag is 0 (step 3212).

If the internal area designation flag is 0, there is no internal area 5673 at the specified position, and the operator can select the basic area 5673.
72 is considered to be specified as a target, and then the number of the basic area 5672 is registered in the table, but at this time, it is determined whether or not the basic area 5672 has already been specified as a target (step 3213). 1 if the basic area 5672 is not specified as a target.
Next, it is determined whether the internal area 5673 is specified as a target (step 3214), and the internal area 567
3 is specified as the target, the operation target area table is cleared once (step 3215), the basic area number and area type are registered in the operation target area table of FIG. 8, and the number of specified areas is set to 1. (step 3216).

Now, if the instruction from the operator is to cancel the designation of the area that is currently being designated as a target, then the page number.

Based on the document data, it is determined which area is specified based on the specified position within the page and the set position of the area.

The area number is deleted from the operation target area table (step 3005 in FIG. 21). The determination method at this time will be explained in more detail using the flow shown in FIG. 22(d).

In FIG. 22(d), it is first determined whether the indicated position is within the basic area 5672 of FIG. Clear unconditionally. That is, the designation of all areas registered in the table is canceled (step 3258). On the other hand, if the specified position is within the basic area %5672 in step 3251, then Step 3252: Step 3252 to determine whether the indicated position is within the area 5672 in order from the area where it is located (the last area in the page).
and 3253), as a result of the determination, the indicated position is the area 5
672, step 32 determines whether the corresponding area 5672 is registered in the operation target area table.
54), if the area 5672 is registered in the operation target area table, the area number is deleted from the table (step 3257); on the other hand, if the indicated position is not within the area 5672 in step 3253, If the area 5672 is not registered in the table in step 3254, step 325
5 and 3256, similar determinations are made for subsequent areas.

However, along with one or more area designation/cancellation operations.

Although the edit operations that can be performed for the area change sequentially, the process of switching between valid and invalid states of the pull-down menu related to area operations (step 3014 in Figure 21) is first performed in Figure 22 (e).
).

By the way, as shown in FIG. 26, editing operations on regions can be classified into three types depending on the number of regions designated as operation targets. That is, first of all, Fig. 22 (e
), the number of areas being specified as a target is determined, the step is performed, and all other area editing is invalidated (step 3302). Also, if the number of areas being specified as a target is 1, conversely, For now, only the pull-down menu for creating a new area is disabled, and all other area editing is enabled (step 3303).

If the number of target areas specified is 2 or more, only move, copy, and delete are enabled, and all other area editing is disabled (step 3304), and if the number of target areas specified is 1, further specification is disabled. Determine whether or not the area is a basic area (step 3305); if the designated area is a basic area, attribute changes and size changes are also disabled (step 3306);
Next, it is determined whether the status of the specified area is other than 0 (step 3307), and if the status of the specified area is other than O (i.e., the area is currently being edited, or the area is not currently being edited in the system). (If there is no area editing department that can update the page number), if the specified number of pages is 1 or more, it must be determined whether there is an area with 5 statuses of 1 (the area currently being edited) among the specified areas. Step 3309)
, if there is an area with status 1 in the designated area, the deletion is also invalidated (step 3310).

Next, in the flow of FIG. 21, the case where the instruction from the operator is to create a new area (step 3006'' in FIG. 21).

This will be explained based on the flow shown in FIG. 22(f).

Incidentally, the operator instructs new creation by instructing the data name displayed by a pull-down menu, but the document editing section 561 in FIG.
According to the pull-down menu number passed from the input control unit 51, the program number and data type number of the corresponding data are acquired based on the SFMT shown in FIG. 27.
Step 3401 in figure (f)), determine which data new creation has been instructed (step 3402)
.

At this time, if the instructed data is data to be created as an internal region t, the area setting of the primary η region and the attribute setting of the region are performed (step 3403).

The eastern part 562 is activated (step 3405). The activation process for the eastern part 562 of area g will be described later.

In addition, in the flow of FIG. 21, if the instruction from the operator is to update an already created area (step 3007 in FIG. 21), the operation in FIG. 28 is performed as shown in FIG. Step 3411 in FIG. 22(g) to obtain the number of the area registered in the target area table.
Based on the number and the data type of the area management block, the program number is obtained from the SFMT in FIG. 27 (step 3412), and the corresponding area editing section 562 is activated as a task (step 3413).

Note that when the area editing section 562 is activated.

First, based on the obtained program number, 1 document editing section 561
requests the system control unit 53 to generate a task (step 3451 in FIG. 22(h)), and stores the task number returned as a result and the number of the corresponding area in the startup editing task management table (hereinafter referred to as (abbreviated as ETMT)
(step 3452).

ETMT has task number 568 as shown in FIG.
8 and area number 5689 as a pair, and also has the number of activated tasks 5687 indicating how many area editing units are currently activated. and.

The status of the area management block is changed from 0 to 1 to indicate that the corresponding area is being edited (step 3453 in FIG. 22(h)). After the above processing, the document editing unit 561 in FIG. requests the system control unit 53 to start the task (step 345 in FIG. 22(h)).
4) Also, send a message to the area editing section that starts the startup parameters (step 3455).
.

At that time, as the startup parameters, the startup mode indicating whether to create a new area or update the area, the task number of the document editing section 561, the task number of the startup area editing section, and, in the case of new creation, the size of the area are transmitted.

If other editing operations are instructed, such as moving or deleting an area, inserting or adding a page, etc., perform the corresponding processing (steps 3008 to 3011 in Figure 21) and wait for the next operator's instruction. (Step 3002).

Now, the instruction from the operator is to change the display page,
For example, if the instruction is for the previous page and the next page (step 3012), the layout of each corresponding page is redisplayed in the window, but the display process for that layout is further explained using FIG. 22(i). Explain in detail.

In displaying this layout, first the paper frame, header, footer, etc. are displayed based on the document data described above (steps 3501 and 3502 in FIG. 22(i)), and then the area set within the page is displayed. are displayed in order from the area with the lowest priority (first area within the page) (step 350).
3 to 3513 and 3514), and when displaying this area, first display the area frame (step 3).
504), Next, it is determined whether an editing program exists for the data in the area based on the data type number in the area management block and the SFMT (Step 3505); if no editing program exists, the area The status of the management block is changed to 2 (step 3511).

In order to notify the operator that there is no editing program for the area in the system, the area is displayed in full black (step 3512).

In addition, in the above, if an editing program exists, the first step is to determine whether the attribute for the area is transparent (step 3506), and if the attribute for the area is opaque, part of the area is cleared. After (step 35
07) Display data within the area (step 3508)
Further, after displaying the area, it is determined whether or not the area is being edited (1 or not) based on the status information for the area (step 3509), and if the area is being edited, In order to inform the operator of this, the entire area is displayed with shading (step 3510).Similar processing is subsequently performed for all areas existing within the page to be displayed (steps 3513 and 3514).

In addition, the process (step 3013 in FIG. 21) for the case of activation input by window switching operation, which will be described later, will be described later.

Further, when an instruction to end is given, editing of one document is ended, and the details of this processing (step 3015 in FIG. 21) will be described later.

Now, in the above processing, when the document editing section 561 requests activation of the area editing section 562, for example, the graphic data editing section due to new creation or updating of a region, the system control section 53, in accordance with this request, creates a new graphic data. Start the data editing department as a task. Here, the processing contents of the 1-graphic data editing section will be explained based on the processing flow shown in FIG. 30.

In FIG. 30, first, the graphic data editing section receives startup parameters by message (step 4001).
, it is determined whether the startup mode is new creation or area update (step 4002). If the startup mode is new creation, the data is initialized (step 4003), and if it is update, the data to be updated is called from the storage unit 3 in FIG. 3 (step 4004), and , the window is opened (Step 4005), and the graphic data is displayed in the window (Step 4006). At this time, the size of the window is set to correspond to the size of the area, and part of the title of the window is
The same task number as the document editing section 561 that is the activation source is added. By adopting the above configuration, when multiple documents are being edited at the same time, and several areas within each document are being edited, which area corresponds to which document can be determined as shown in Figure 32. It can be easily identified by the task number 254 displayed as part of the window title, as shown in FIG. Further, at this time, the display state of one screen is as shown in FIG. 31(b). Now, let's move on to the graphic data editing department.

In the set window, graphic data is created and assembled according to instructions from the operator (steps 4007 to 4009). In addition, the graphic data editing department is
When the operator instructs to finish editing within the area 1. Store the created graphic data in the storage unit 3 shown in Figure 1.
Step 4010) in the figure, closes the window (Step 4011), sends an area editing completion message to the document editing unit 561 that started it (Step 4012), and ends the task (Step 4013). In order to enable the started document editing section 561 to determine which region has been edited, an end code indicating the completion of editing within the region and a task number of the graphic editing section itself are set.

As described above, you can create and edit the entire document and each area.
This will be explained using the drawings and FIG. 17.

First, as shown in FIGS. 31(b) and 31(c), when switching to document layout editing while editing the graphic area, the document editing section 561 window Move the mouse cursor 30 in FIG. 2 upwards and press the mouse execution button 3 indicated by reference numeral 31 in FIG.
11 is pressed. It is determined that it is outside the window of the figure editing section.

This input is passed to the window management section 52 instead of the graphic editing section. The window management unit 52 controls the position indicated by the mouse 31, and also the window management table 52 in FIG.
It is determined that the window of the document editing section 561 has been designated from step 1 (step 1521 in FIG. 17), and the task that has been using the topmost window, that is, the figure editing section, is temporarily interrupted (step 1522). Also, saves the display image of the topmost window to the display buffer (step 1523), displays the newly designated document editing section window at the top (step 1524), and updates the stacking order of the window management blocks. Step 1525).

In step 1526), an activation code is returned to the window usage task in order to notify the document editing unit 561, which restarts the process, that the window has been switched. 561 (step 1527).
).

The suspension and resumption of the editing section is performed by the system control section 53.
Processed in Below, Figure 12(e) and 1
Based on the flow in Figure 2(f).

The processing of suspending and resuming the editing department will be explained.

When a task interruption request occurs, the system control unit 53 in FIG.
Please set the interrupt flag (see reference numeral 532 in the figure).
Step 1141 in Figure 2(e)).

It is determined whether the task is in the READY state (step 1142), and if the task is in the READ' state, the corresponding TCB 532 is set to READY in FIG.
It is removed from the Y queue 533, and is prevented from being assigned a CPU by the task dispatcher 1013 in FIG. 12 (step 1143).

In response to a task restart request, the interrupt flag of the TCB 532 corresponding to the specified task is reset.
Step 1151) in figure (f), the task is READ
It is determined whether the task is in the Y state (step 1152), and if the task is in the READY state, the corresponding TC is
Connect B to the READY queue 533 (step 11
53).

If the interrupt flag of TCB532 is set,
The task dispatcher 1013 does not activate the task and removes it from the READY queue 533.

Furthermore, if the basic area is updated from the state shown in FIG. 31(Q), the nine screens will change as shown in FIG. 31(d). In this state, each editing section can be switched between text, graphics, and layout using the same operation method as described above.

It can be done arbitrarily. For example, between area editorial departments.

That is, when switching from text to graphics, the screen display state becomes as shown in FIG. 31(e).

Now, when the window is switched as described above, the activation code is returned as input to the task restarted from the window management section. conduct(
Figure 22 (j) and (k)).

That is, first, it is determined from the document data whether or not the area being edited exists within the currently displayed page (step 3601 in FIG. 22(j)), and the area being edited exists within the currently displayed page. If so, set the 1g display flag to 0 (step 3602), and if the 1g concentrated area does not exist in the page currently being displayed, step 3603), after processing the following message, redisplay the layout. 0th order,
A message reception request is made to the system control unit 53 in FIG. 1 (step 3604), and if there is a message (step 3605), the next process is performed as a termination process for the corresponding area editing unit (step 3606). That is, first, the task number of the area editing section stored in the message, and further the area number is obtained from the ETMT (Fig. 29) (step 3651 of Fig. 22(k)), and the status of the corresponding area management block is obtained. Reset to O (step 3652), and delete information regarding the task from the ETMT in FIG. 29 (step 3653).

Finally, delete the dance task itself (step 36
54), Now, in step 3605 of FIG. 22(j), if there are no more messages, the display flag is set to 1.
Step 3607
), if the display flag is set to 1, the layout of the page is redisplayed (step 3608).

Here, regarding the termination process in the document editing section 561,
This will be explained using FIG. 22(Q) and FIG. 12(g).

If the operator instructs you to terminate, please follow the above E.
Based on the TMT (Figure 29), it is determined whether or not there is a running task. Step 3 in Figure 22 (Q)
702), if there is an active editing task, the second
After acquiring the task number and area number from the ETMT in Figure 9 (Step 3703) and resetting the status of the area to 0 (Step 3704), a request for forced termination of the task is made to the system control unit 53 in Figure 1. (Step 3705), in accordance with this request, the system control unit 5
Step 3 first releases the resources used by the designated task (step 1161 in FIG. 12(g)).

Make a forced termination request to window management (step 1)
182), in window management, the same process as the close process shown in FIG. 16 is performed, and based on the specified task number, the corresponding TCB (reference numeral 532 in FIG. 8)
If the TCB 532 is connected to the READY queue 533 in FIG. 9, the TCB 532 is removed from the READY queue 533 and the state of the TCB is set to the DORMANT state (step 11%3).

After the above forced termination process, the one-document editing unit 561 deletes the task (step 3706 in FIG. 22(Q)).

Then, the process is repeated for the editing tasks that are running (step 3707), and when the forced termination of all running tasks is completed, the document data is registered (step 37).
08), the document editing department closes the window that it had opened itself (step 3709), sends a message to the system management department 57 in FIG. In step 3711), when a termination request is made to the one-document editing section 561 in this manner, the area editing sections that are being edited can be terminated all at once.

〔Effect of the invention〕

The present invention is as described above, and as is clear from the description of the illustrated embodiment, according to the present invention, during the editing execution of an editing section, a switching operation is performed to another editing section, and then an operation is performed to switch to another editing section. Before the editing department resumes editing, the original page layout can be quickly redisplayed. Therefore, the operator can immediately recognize the page layout that is in the process of editing, and the document creation device is not required. Operability can be improved more than before.
