JP2540940B2 - Multi-window editing management method - Google Patents

Description

The present invention relates to a multi-window edit management method in an information processing apparatus having a plurality of multi-windows that can be positioned at arbitrary places in the same file.

[Conventional technology]

When editing the contents of a file, it may be necessary to refer to / update one location of the file while referring to / update another location of the same file content. For example, if the contents of the file are source information, in the development of the program, while referring to the variables of the program, update the procedure part of the same program in another place, or update another variable of the same program. There is a case to do. In the case of object information, the value of an object in another place of the same file may be updated while referring to the value of the object.

In this case, if multiple points in the same file cannot be edited in multiple windows at the same time, the operator, that is, the person who edits the file, stores the information of one point in his / her head, Alternatively, it is necessary to move the screen to another location in the same file by scrolling after performing a procedure such as recording the information of one location by writing or the like, and update the information according to the above-mentioned storage or recording. is there. The operation of storing or recording and the operation of moving the screen have to be repeated many times, which causes a problem that the efficiency of the editing work is significantly reduced.

[Problems to be Solved by the Invention]

Regarding the solution of the above problem, for example, Japanese Patent Laid-Open No. 60-1285.
The technique disclosed in Japanese Patent Publication No. 73 is known. In this technique, the window display routine is configured independently of the text editing routine, and the window display routine prepares the same number as the number of windows. At one time, the window display routine and the text editing routine of the window used at that time are prepared. This is a method in which the window display routine and the text editing routine are separated from each other by connecting and, and it is possible to edit a plurality of different places in the same text, but there are the following problems.

That is, (1) window display routines corresponding to the number of windows to be used are required, and a large amount of memory is required to store a plurality of window display routines.

(2) When the window display routines other than the window display routines of the windows that are combined at a certain point are separated from the text editing routine, the display locations may partially overlap between multiple windows. , If you change that point in the text editing routine,
The display contents of the window displayed by the window display routine separated from the text editing routine remain the old text portion, and the correct text is not displayed.

Therefore, in the above technique, it is necessary to perform any of the following (a) and (b).

(A) The text part displayed in each window is always
Control so that they do not overlap each other.

(B) Although the text portion displayed in each window can be duplicated, the display content of the duplicated portion is not guaranteed except for the window that is the editing target at that time.

However, in the case of the above (a), even when the portions displayed by the plurality of windows are very close to each other in the file, the window switching operation by the operator is always required, There is a problem that the reduction of editing work efficiency due to window switching operation is unavoidable. Further, in the case of (b) above, it is necessary for the operator to remember in his / her mind which window that has been cut off is not displaying the correct text. There is a problem that it causes a significant decrease in the efficiency of.

The present invention has been made in view of the above circumstances, and an object of the present invention is to solve the above-mentioned problems in the conventional technique and to provide a plurality of windows that can be positioned at arbitrary positions in the same file. In addition to realizing multi-window editing, it also allows overlapping of each position (range) in the same file displayed by multiple windows, and the contents displayed in each window match the latest state of the edited result. It is to provide a multi-window edit management method adapted to do so. Another object of the present invention is to realize the above-mentioned method by suppressing an increase in the required memory amount accompanying the increase in the number of windows.
It is to provide a multi-window edit management method.

[Means for solving the problem]

The above-mentioned object of the present invention is to display a plurality of windows capable of displaying / changing / adding / deleting contents at any place in the same file, and displaying the plurality of windows on a display device (20). An information processing apparatus including a control table (40) for common management of information such as ranges, a command etc. analysis routine (13), one data editing routine (12) and one window display routine (11) ( In the multi-window edit processing method in 10), when updating the data in the file, the input command etc. is analyzed by the command etc. analysis routine (13) and the analysis result information is sent to the data edit routine (12). The data edit routine (12) updates the data in the file based on the information notified from the command etc. analysis routine (13), and the control The display range stored in the table (40) is automatically searched to determine the window containing the updated data, the information of the determined window is notified to the window display routine (11), and the window display is performed. The routine (11) is achieved by a multi-window edit management method for displaying updated window data based on the window information notified from the data editing routine (12).

[Action]

In the multi-window edit management method according to the present invention, the multi-window edit management method has a control table for managing information such as display ranges of a plurality of windows on the display device, and when the data corresponding to the display content is changed, the same file The relevant part where the display of other windows displaying the contents of is duplicated,
Since the contents of each window are updated by referring to the contents of the control table, the contents displayed in each window can be always matched with the latest state of the edited result. Is configured by a single program routine (window display routine), it is possible to prevent an increase in the required memory amount due to an increase in the number of windows.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing a schematic configuration of an embodiment of an information processing system for executing the multi-window edit management method of the present invention. In the figure, 10 indicates an information processing device which is a main part of the information processing system, and 11
Is one window display routine for displaying the data in the window on the display device 20, 12 is one data editing routine for editing the data in the file (reference / update / change / addition / deletion, etc.), 13 Shows one command analysis routine for controlling the input of all commands and data input from the input device 30 such as a keyboard.

The display of data and the like on the display device 20 by the window display routine is generally performed by transferring the data to the display device 20 or writing the data to the memory of the display device 20, and the display content is the display device. It is retained on the display device 20 unless the window display routine directs a new display of 20 at the same position. The display device 20 and the input device 30 (collectively referred to as “input / output device”) described above are usually
It is placed at a close range. Further, when the information processing device 10 and the input / output device are separated from each other, a communication line, a relay information processing device, or the like may be inserted at the position indicated by ● in the figure.

An outline of the operation of the information processing system of this embodiment configured as described above will be described below.

The command analysis routine 13 analyzes the command and data input by the operator using the input device 30, and based on the analysis result, calls the data edit routine 12 or the like as necessary, and the data edit routine 12 is called. , Requests processing such as reading the data in the file to the data editing area 14, updating the data in the data editing area 14, writing to the file from the data editing area 14, and the window to be used thereafter. Information is notified.

The data edit routine 12 performs the processing requested by the command analysis routine 13 described above, and when the data in the data edit area 14 is updated, the window display routine 11 is called as appropriate to handle the changed data. The display of data on the display device 20 is changed. This window display routine 11 is called by the window that the data editing routine 12 is currently editing, that is,
All of the data related to the data in the data editing area 14 updated by the data editing routine 12 as well as being executed for any one of the windows 1, 2, 3, and 4 in FIG. It is performed as many times as the number of windows. The range displayed by one call of the window display routine 11 is
Limited to one window. For example, window 1
1 is a display within a square range in which the left end of the dotted line indicated by and the left end of the dotted line indicated by are a pair of diagonals. Similarly, window 2,
If the display is for 3 and 4, respectively,
Is a display within the range of a square with the left end of the dotted line of;

As described above, when the data edit routine 12 calls the window display routine 11 a plurality of times for updating one data, the window to which the window display routine 11 is called is determined in the control table as described later. The display range stored in (1) is automatically determined by the data editing routine 12 searching, and the command etc. analyzing routine 13 and the operator operating the input device 30 need not intervene. As indicated by the dotted line indicated by in FIG. 1, only the data editing routine 12 writes / reads to / from an arbitrary portion of the data editing area 14. Further, the display range stored in the control table is, if necessary, when the data editing routine 12 is called from the command etc. analysis routine 13 in accordance with the command etc. inputted by the operator using the input device 30. The data edit routine 12 is to be changed.

The window display routine 11 is the data editing routine 12
When called by etc., the data etc. are displayed on the display device 20. In that case, the window display routine 11 receives the information indicating the physical configuration of the window on the display device 20 at the time of calling and displays the information according to the information, and therefore does not directly recognize which window the display is to be performed. Only a predetermined process is performed according to a plurality of data (window information) passed from the data editing routine 12 or the like via a register or a memory. Therefore, the display window is different only in the window information passed from the data editing routine 12 and the like, and only one window display routine 11 is required. That is, as the number of windows increases,
Only the number of data such as the above-mentioned control table managed by the data editing routine 12 and the command etc. analysis routine increases. This will be described in detail below.

FIG. 2 shows a configuration example of the control table. In addition,
In the figure, only one is shown to simplify the description. The control table 40 according to the present embodiment is (a) a target file name in the edit target file management control table existing for each multi-window edit target file, (b) the number of windows that simultaneously reference / update the file,
(C) Consists of information for each window. Further, in the (c) window information, as shown in (1) to (2) of FIG. 2, there is information for each window corresponding to the number of (b) windows described above.
(D) Top line number of the window on the display device,
(E) Last line number of the window on the display device,
(F) First digit number of the window on the display device,
(G) Last digit number of the window on the display device,
(H) The first line number in the displayed data editing area in which the first line of the window is displayed, (i) The last line number in the displayed data editing area in which the last line of the window is displayed, (J) Line number on the cursor display device of the window, (k) Column number on the cursor display device of the window, (l) Line number on the data editing area of the cursor of the window, (m) It consists of the digit number on the data editing area of the cursor of the window. From (h) the top line number in the displayed data editing area in which the top line of the window is displayed, (i)
The range up to the last line number in the displayed data editing area displayed by the last line of the window is called the display range.

Also, the data in the data editing area in FIG.
(A) The data is made up of multiple lines divided by information indicating line breaks, or (b) it is made up of multiple lines of a fixed length. Manage by dividing.

In addition, as shown in FIG. 2, (y) presently selected file name address storage area and (z) presently selected file, which shows which “window” of “what” file is currently being edited. There is one selection window address storage area, and information of the above (a) target file name in any one of the plurality of edit target file management control tables and a plurality of files immediately after the (a) target file name. (D) One of the addresses of the first line number of the window on the display device is stored.

In FIG. 2, (b) the number of windows for simultaneously referencing / updating the target file and the number of windows information such as to are always the same, and according to the command input by the operator via the input device 30, Command analysis routine 13
Will be updated if necessary. The above (a), (d),
The same applies to the information of (e), (f), (g), (y), and (z).

On the other hand, the above (h), (i), (j), (k),
The operator inputs the information of (l) and (m) with the input device 30.
When the data editing routine 12 is called from the command etc. analysis routine 13 according to the command input via
The data edit routine 12 changes as necessary. The contents of the control table 40 shown in FIG. 2 are appropriately loaded into a register or the like and used in order to shorten the time for performing those processes.

When the window display routine 11 shown in FIG. 1 is called from the data edit routine 12 or the like, the window display routine 11 exists in the "information for each window designated by the calling source" (d) to
(M) and the information such as the above (a) of the processing target designated by the caller is referred to, and the data is displayed in the window.

When the data editing routine 12 shown in FIG. 1 is called from the command analysis routine 13 to update the contents of the data editing area, each window of the window pointed to by the (z) currently selected window address storage area is The contents of the data editing area are updated based on the information (any one of FIG. 2), and the window display routine 11 is called to display the window information currently being edited on the display device. For example, in FIG. 2, the shaded portion of the data editing area 14 is based on the information in the window 1 of
14a is updated, and (d) at the beginning of the information in window 1 of
The window display routine 11 is called by specifying the address of the first line number of the window on the display device, and the window information currently being edited is displayed on the display device. At the same time, the updated data edit is performed. The line number of the contents of the working area is a window other than the window information pointed to by the (z) currently selected window address storage area,
Here, the control table pointed to by (y) the currently selected file name address indicates whether or not it is included in the display range of the window information of window 2, window 3 or window 4 (any of FIG. 2). A check is made by referring to the information of (h) and (i) in the window-by-window information of all the windows inside (all except window 1 here), and the "currently selected window" shown above is checked. "
If any window is included in the display range area of any other window, the window display routine is appropriately called by designating the address of the window information of the window.
As a result, the display contents of the relevant line of all the overlapping windows are changed to the updated contents of the data editing area.

The term “call” in the above description includes an implementation mode in which a plurality of calls are simultaneously executed in parallel by taking the form of a processing request to a task or a process.

FIG. 3 shows an example of the processing flow of each program at the time of updating data when the above-mentioned parallel execution is not involved.

Now, it is assumed that the file contents have already been read into the data editing area 14 shown in FIG. 2 and four windows have been created. It is assumed that you are waiting for. In this state, when the operator inputs a data update command from the input device 30, the command analysis routine 13 receives the command (step 52) and checks whether the command is a data update command. The determination is made (step 53). Here, since the received command is a data update command, the process proceeds to step 54 and waits for the arrival of update data.

When the operator inputs the update data, the command etc. analysis routine 13 receives the command (step 52).
55), the process proceeds to step 56, where the data edit routine 12 is called in order to request the data edit routine 12 to update the data.

When the data edit routine 12 is called, step 58
Then, the processing request is determined. In this case, since the data is updated, the process proceeds to step 59, and the address information of the edit target window 1 at the current time is obtained from the storage area of the (z) current time selected window address described above (see FIG. 2), and the information is updated. And the data passed when it is called, the data in the data editing area 14 is updated.
After that, go to step 60 to display the updated result on the display device.
To display the update data, specify the window information address indicated by the currently selected window address, etc. to display at 20, and request the display of update data.
Call 11.

When called, the window display routine 11 determines in step 70 what the processing request is, and in this case, the update data display request.
The data is displayed in the window 1 on the basis of the window information etc. passed from (step 71) and the process returns to the data editing routine 12. When the window display routine 11 finishes processing in step 60, the data editing routine 12 proceeds to step 61, in which the number of windows ((b) above)
Check. In this case, since the number of windows is 4, the process proceeds to step 62, where the file to be edited indicated by the above-mentioned (y) current selected file name address storage area is set as the initial setting process for searching all windows. The address of the top window information in the management control table 40 is obtained, and that address is set in the work area called address A (step 62). In this case, the address A is the address of the window information of window 1. In the following description, “address A” means the contents of this work area.

After that, in order to search for a window whose display range overlaps, the process proceeds to step 63, and a determination is made to select a duplication for a window other than the currently selected window. Here, the address A matches the currently selected window address. , Go to step 66. In step 66, it is judged whether or not the display ranges of all windows have been checked. In this case, since it is the processing of window 1, the process proceeds to step 67, and in step 67, the next window is checked. To do so, the address of the next window information is set in the address A. Where address A
Is the address of the window information of window 2.

After that, the process proceeds to step 63 again, but since the address A is different from the currently selected window address, the process proceeds to step 64, and at step 64, the display in the window information of the window indicated by the address A (in this case, the window 2) is performed. Range (between (h) and (i) in window 2 in Figure 2)
Determines whether the update data is included in. If it is included, the process proceeds to step 65, the window display routine 11 is called to request the window display routine 11 to display the update data by designating the address A etc. Based on the above, the data (of the windows whose display is overlapped) is displayed on the display device 20 (steps 70 and 71), and the process returns to step 65,
Then, it progresses to step 66.

In the above case, the display process of window display routine 11 is
Only the processing that is the same as when it is called in step 60 is performed, and it is not directly conscious of which window the display is. In other words, the difference when the window display routine 11 is called differs only in the information passed at the time of calling, and since the information includes the physical information of the window, the logic of the window display routine 11 is 1
It ’s all right.

In the determination in step 64 described above, the address A
If the display range in the window information of the window indicated by does not include update data, the process proceeds to step 66 without passing through step 65, and in step 66, it is determined whether all windows have been checked again. . If all the windows are not checked, the process proceeds to step 67, and the processes similar to the process for the window 2 described above (steps 67 and 63 to 66) are performed on the windows 3 and 4. Step 66
When it is determined that the processing of all windows (here, four windows) is completed, the data editing routine
12 returns to the command analysis routine 13.

As described above, the data edit routine 12 automatically determines all the windows in which the update data is displayed in duplicate, and displays all the display states of the windows in which the display is duplicated,
It can be controlled to be up to date.

The format, processing operation, etc. of the control table 40 in the above-mentioned embodiment are shown as an example, and the present invention should not be limited to this.

〔The invention's effect〕

As described above in detail, according to the present invention, a control table for managing information such as display ranges of a plurality of windows on a display device is provided, and when data corresponding to display contents is changed, By updating the relevant part where the display of other windows displaying the same file is duplicated by referring to the contents of the above control table, the contents displayed in each window are always It becomes possible to match the latest state of the edited result, and the above method can be realized while suppressing the increase in the required memory amount accompanying the increase in the number of windows.
