The present invention relates to an input data processing display method using a plurality of cursors for displaying contents.

[Conventional technology]

Until now, as shown in JP-A-60-132227 and JP-A-61-82224, a plurality of cursors are displayed on a display screen, and one of them is selected. Moving and being used.

[Problems to be solved by the invention]

By the way, various characters and symbols are generally displayed on a display screen. At this time, for example, the same character or character string is often displayed at a plurality of places. In such a case, for example, even if a plurality of cursors are displayed, an operation of moving a cursor selected according to the display position to the display position and inputting character data has been performed so far. This operation must be performed a plurality of times, and the operability in the case where the same character string or the like is displayed at a plurality of places is not considered.

SUMMARY OF THE INVENTION An object of the present invention is to provide an input data processing and displaying method using a plurality of cursors that can be performed with good operability when it is necessary to display the processing content of the same input data at a plurality of locations on a display screen. To serve.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a display unit for displaying display data and a cursor, a data input unit for inputting display data to be displayed on the display unit and control data for updating the contents of the display data, A display device, comprising: cursor moving means for instructing movement of a cursor; and data processing means for displaying display data input from the data input means on a display means and for updating display data content of a cursor position in accordance with the control data. In the input data processing and display method, a plurality of the cursors are displayed in a fixed manner with respect to each other in accordance with an instruction of the cursor moving means, and are moved by the same amount in the same direction while maintaining the fixed display relations. The display data at the plurality of cursor positions based on the control data input by the data input means. It is characterized by being updated with one content and displayed.

[Action]

An arbitrary number of external cursors are initially displayed at arbitrary positions on the display screen, but these cursors are also updated relative to the initial position data corresponding to the cursor based on the cursor movement command data. It is possible to move in conjunction with the up, down, left, and right directions while maintaining a typical positional relationship. Therefore, for example, when data on a character to be displayed is input, the character is simultaneously displayed at the position of each cursor, or when data indicating that the character currently being displayed is to be deleted is input. , The characters displayed at the positions of the cursors can be simultaneously deleted.

〔Example〕

 Hereinafter, the present invention will be described with reference to FIGS.

First, a personal computer as a display device according to the present invention will be described. FIGS. 2 and 3 show an external configuration and a functional block configuration, respectively, as an example. In this case, the whole is roughly composed of a keyboard 1, a processing device 2 as a main body, and a display device 3. A large number of operation keys are arranged in a predetermined manner on the keyboard 1. When each of the operation keys is pressed, data corresponding to the operation key is input to the processing device 2, and a process corresponding to the data is executed. It has become something. As shown in detail in FIG. 3, the processing unit 2 has a microprocessor 2-1, a ROM 2 for storing various programs, and a bus 2-4.
2. Work processing RAM 2-3, RA for storing text display information
M2-5 and cursor display device 2-6 for cursor display
Are connected. The microprocessor 2-1 selects a program from various programs stored in the ROM 2-2 or the RAM 2-3 and executes the selected program to perform predetermined processing designated by the keyboard 1 or the like. In addition, character data and the like input from the keyboard 1 are stored in the RAM 2-5 as updatable and displayed on the display screen of the display device 3. RAM2-5 corresponds to the display screen, and its predetermined address position (corresponding to the cursor display position)
If a character is stored as a code in the display device 3, the code is converted into a character pattern by the character generator on the display device 3, and the character is displayed at a display position corresponding to the predetermined address position on the display screen. is there. A cursor is also displayed on the display screen as an indication of a processing target display position in addition to characters and the like. The display position of the cursor 4 can be updated in the cursor display device 2-6. This is based on the cursor display position data stored as.

Normally, only one cursor is displayed on the display screen. However, in the personal computer according to the present invention, an arbitrary number of cursors are displayed as being simultaneously usable on the display screen, so that it is possible to execute peculiar processing. Has become.

First, the setting of the initial setting display positions of a plurality of cursors will be described. For example, the setting is input from the keyboard 1. A predetermined area for storing the cursor position storage table 5 shown in FIG. 4 is provided in the RAM 2-3 in advance, and according to the cursor initial setting processing flow shown in FIG. Initial display position data for each of the cursors (1) to (i) is stored in a predetermined format as X and Y coordinates. In this example, the X and Y coordinate values corresponding to the cursor are input directly from the keyboard 1 as numerical data. Each time the cursor normally used is moved to the initial setting display position, the X and Y coordinate values are read from the display position storage area in the cursor display device 2-6, and may be used as the initial setting display position data. It is possible.

After the X and Y coordinate values corresponding to the cursors (1) to (i) are initially set in the cursor position storage table 5 as described above, processing by a plurality of cursors can be executed based on these data. FIG. 6 shows a flow of a general key input process considering the process. In this case, at the time of key input processing, it is determined whether or not the data first input from the keyboard 1 is from the cursor operation mode switching key. If it is determined that the current cursor operation mode is the one after that, it is determined whether or not the current cursor operation mode relates to a plurality of cursors. If the operation mode is the multiple cursor operation mode, the cursor operation mode is switched to the normal cursor operation mode, and the key input process is performed by the normal cursor operation thereafter. If the cursor operation mode has been the normal cursor operation mode, the cursor operation mode is switched to the multiple cursor operation mode, and the key input processing is performed by the multiple cursor operation thereafter.

If it is determined that the input data is not from the cursor operation mode switching key, key input processing is performed in accordance with the cursor operation mode up to that time.

The key input processing (multiple cursor processing) by the multiple cursor operation directly relates to the present invention, but FIG. 1 shows a basic flow of the processing. For example, assuming that a certain character or symbol is simultaneously displayed at the display position of each cursor, character data or symbol data input by a key from the keyboard 1 is temporarily stored in the RAM 2-3, and is temporarily stored at the display position of each cursor. At least until the character or symbol is displayed. On the other hand, when the cursor movement key is operated, the X and Y coordinate values corresponding to the cursor (1) from the cursor position storage table 5 are stored in the microprocessor 2-
1, is stored in the display position storage area in the cursor display device 2-6, and is also stored in the cursor position storage table 5. Based on the updated X and Y coordinate values, the microprocessor 2-
1, the address on the RAM 2-5 is calculated, and the character or symbol code is stored at the address position, so that the character or symbol is displayed at the display position of the cursor (1) on the display screen of the display device 3. This is where the symbol will be displayed. The above processing is sequentially performed for each of the cursors (2) to (i), so that the display positions of the cursors (1) to (i) translated in the horizontal direction or the vertical direction from the initial display position are displayed. Characters or symbols can be displayed simultaneously. When deleting characters, symbols, and the like already displayed at the display positions of the cursors (1) to (i), the same operation can be performed.

Here, the case where the multi-cursor processing is applied to the tabulation program processing will be described more specifically with reference to FIG.

In other words, in the tabulation program processing, ruled lines may be drawn with non-uniform intervals, or the same character or the same character string may be displayed in certain items. In such a case, the multiple cursor processing is extremely effective. It is that.

First, when the ruled line needs to be drawn as shown in FIG. 7, a cursor is placed at each of the display positions of the first digit, the first, third, fifth, seventh,. In order to display the initial setting, each cursor is initialized and the cursor operation mode switching key is used to put the cursor into a plurality of cursor operation mode states. This allows each cursor Is displayed at the initial setting display position as shown in FIG. If horizontal ruled line data (-) is input from the keyboard 1 in this state, horizontal ruled lines are simultaneously displayed at the display positions of the cursors. If horizontal ruled line data is input each time the cursor is moved
All the horizontal ruled lines of the table required in the key input processing are drawn all the time, and the key input processing and the ruled line are drawn in a much shorter time than in the case of drawing in ruled line units. Become. The same applies to the vertical ruled line.

Next, the simultaneous display of a plurality of character strings will be described.
In the table shown in the figure, the column for permanent residence is all "Same as left (April 1988)
Month)), each cursor is moved to the display position of each
“Left”, “(”, “sho”, “sum”, “6”, “3”,
By inputting “year”, “4”, “month”, “current”, “current”, “)” in sequence, the fourth, sixth,. (As of April 1963) "will be displayed.

The basic multi-cursor processing has been described above.
The present invention is also effective when copying a character string or the like which is already displayed at another display position. For example, in FIG.
Although the permanent domicile is all displayed as "same left", the "address" displayed on the left side instead of "same left" is to be copied directly to the "same left" display position.
In this case, the cursor is moved to the head position of each character string indicating the "address" display to indicate that it is the head of the copy source, and then the cursor is moved to the end position of each character string to reach the end. Then, the cursor may be moved to the head position of each copy destination to indicate that it is the head of the copy destination. Since the character string information of each copy source on the RAM 2-5 is specified in correspondence with the cursor from the start information and the end information of the copy source by the cursor, the character strings can be simultaneously copied at each copy destination. If the instruction frequency is high, the key corresponding to the start or end is indicated by a function corresponding key if the instruction frequency is high, and if the instruction frequency is low, it is indicated using a menu or icon display. Good.

Furthermore, the multi-cursor processing is also effective when moving a character string or the like that is already displayed to another display position. According to the example shown in FIG. 7, if "same left" is to be replaced with "address" displayed on the left, "(Showa 63
(As of April) overflows from the item column, and it is necessary to move the character string to the right. When moving, the cursor is moved to the source character string in the same way as in the case of copying, and the head and the end are instructed, and then the destination head may be indicated by the cursor. Alternatively, if a specific color is used, the position of the source character string is specified. In addition, the movement of the movement source character string to the movement destination includes a mode in which the movement is performed according to the movement of the cursor to the movement destination, and a method of specifying the movement destination head position by the cursor.
There are modes of simultaneous movement, but these are easily realized by a known technique using a cursor.

Although the processing using a plurality of cursors has been described above, it is obvious that this processing can be applied to the processing using a single cursor in general.

〔The invention's effect〕

As described above, according to the present invention, the processing contents of the same input data are displayed simultaneously at a plurality of positions on the display screen with good operability by a plurality of cursors.
