The framework can be easily and quickly formed through simple operations.

[Prior Art] In conventional character processing devices of this type, it has been necessary to input indents one by one by key operations on a keyboard, and to sequentially form an indent framework by repeating such key operations.

[Problem to be Solved by the Invention] Therefore, in this type of conventional character processing method, when setting the framework used for character string editing, settings must be made on the display screen, and However, the disadvantage was that it was difficult for the operator to understand the set framework.

Therefore, in view of the above points, the object of the present invention is to
To provide a character processing method that allows an operator to easily operate and confirm the contents of the set framework when setting a framework.

[Means for Solving the Problem] In order to achieve such an object, the present invention has the following features:
In order to set the framework to be used for character string editing, input multiple numerical information indicating the row and digit positions where the framework is formed, and set the maximum and minimum values of the input multiple numerical information in the row. direction and digit direction, and generate pattern information representing a framework in rows and columns indicating the plurality of numerical information within a range defined by the determined maximum value and minimum value, and The present invention is characterized in that the position and size of the framework are displayed so as to be visible based on the pattern information obtained.

[Operation] In the method of the present invention, by inputting the positions of rows and columns in which a framework is formed in numerical form, pattern information indicating the framework of the rows and columns is generated based on those numerical values. By displaying this pattern information, the operator can easily and reliably know the position and size of the set framework.

[Embodiment] First, an example of the overall configuration of the character processing device of the present invention is shown in FIG. In the illustrated configuration, the CPU is
A central processing unit, that is, a so-called microprocessor, performs arithmetic operations and logical judgments for character processing, and is connected to these buses via the address bus AB, control bus CB, and data bus DB. Control each component. Of these buses, that is, common signal lines, the address bus AB transmits address signals that specify the components to be controlled by the microprocessor CPU, and the control bus CB transmits address signals that specify the components to be controlled by the microprocessor CPU. A control signal is transmitted and applied to each target component, and further,
The data bus DB transfers and receives data between each component.

Next, the ROM is a read-only fixed memory device, and stores control procedures and the like by the microprocessor CPU, as will be described later with reference to FIGS. 4 and 5. Further, the RAM is a writable random access memory having, for example, one word of 16 bits, and is used to temporarily store various data from each component. In addition, K.B.
is a keyboard in which various key groups for inputting various data and giving commands in this character processing device are configured and arranged as shown in FIG. 2, for example.

Therefore, the keyboard with the configuration shown in Figure 2
In KB, CIK is a group of various keys such as character keys and function keys for character processing, and WK is a framework formation command key that instructs the formation of a framework for setting a desired area by indentation. It is. Here, indentation refers to data for configuring a framework.

Next, the CR in the overall configuration shown in the first diagram is
A cursor register and a microprocessor register.
A memory device that is controlled by the CPU and writes and reads data related to the position of the cursor on the display screen, and is a CRT controller that will be described later.
This cursor register under the control of the CRTC
Move the cursor to the display position on the CRT display screen that corresponds to the address stored in the CR and display it.
Further, DBUF is a data buffer memory, which is a memory device for storing text information input by key operations on the keyboard KB,
The stored text information is displayed on the CRT display screen under the control of the CRT controller CRTC. In addition,
This data buffer memory DBUF will be described later.
It is used as a refresh memory for a CRT display device, and can be controlled by a microprocessor CPU to perform arbitrary writing and reading.
In addition, this data buffer memory DBUF represents, for example, each character in one word.
For example, assume that the device has a storage capacity of 16×10 words, and the character strings of the storage contents are displayed on the CRT display screen. The display of characters on the CRT display screen is, for example, 16 characters horizontally and 10 lines vertically, and the 160-word character strings stored in the data buffer memory DBUF are displayed in correspondence with each other. do. In addition, data buffer memory
The data to be stored in DBUF is sequentially numbered from 1 to 160, and DBUF1, DBUF1,
DBUF2,... and generally, the Nth data is expressed as DBUF(N), and the code signal representing each character is stored in this data buffer memory.
It shall be stored in DBUF.

Next, a CRT is a display device using a cathode ray tube or the like, and a CRT controller CRTC, which controls the dot-configured display pattern and cursor display on the display device CRT, controls the cursor register CR and data buffer memory DBUF. The display of the cursor and display pattern on the display surface of the display device CRT is controlled based on the respectively stored cursor position and character code signal. Further, CG is a character generator that generates character signals such as characters and cursors to be displayed on the display device CRT, and each character is displayed in a 16×16 dot configuration, for example.

Next, an outline of the operation of the character processing apparatus of the present invention having the above-described circuit configuration will be explained with reference to FIGS. 3A and 3B. All operations in the device of the present invention are performed by operating character keys or function keys on the keyboard KB.

First, when the power is turned on, as shown in FIG. 3A, on the display screen of the display device CRT, only the cursor CM is displayed at the top left corner, and the following keys on the keyboard KB are displayed. The display is performed according to the character processing operations performed by the user. In other words, characters entered by key operations on the keyboard KB are displayed at the position where the cursor CM is displayed on the CRT display screen, but the cursor changes every time a character is input from the keyboard KB. , its display position advances. Note that such signal input control can be easily realized using commonly used techniques.

Next, in the character processing device of the present invention, in order to configure an indent framework, the numbers of the lines and columns on the display surface where the indents are to be arranged are determined as follows.
Enter the letters "R" and "C" separated by commas using the comma key. In addition,
Those letters “R” and “C” are, respectively,
It is an acronym for row (ROW) and column (column). That is, for example, as shown in Figure 3A, enter R, 3, 6, 9 for the rows and C, 2, 5, 8 for the digits, and then press the frame key WK. When you press , the indent IDs are arranged from the 3rd line to the 9th line and from the 2nd digit to the 8th digit, as shown in Figure 3B.
As an inner partition, the indent IDs are lined up in the 6th line and the 5th column to form a frame and are displayed.

Next, the structure of the indentation framework and display operation means described above will be explained with reference to the flowcharts shown in FIGS. 4 and 5. After the power is turned on, if a key operation is performed on the keyboard KB while the keyboard is in standby mode in step S1, it is determined in step S2 whether the key input was due to the operation of the frame key WK or not.
It is determined whether the operation was due to the operation of another character input key CIK, and if it is due to the press of the frame key WK, frame display processing is performed in step S3, and if the operation is due to the press of the character input key CIK. If so, character input processing is performed in step S4. After these processes are completed, the process returns to step S1 to return to the key input standby state again.

For details of each processing process mentioned above, first,
In the normal character processing process, the character code signal from the key input from the keyboard KB is sent to the cursor CM.
Data buffer memory DBUF corresponding to the location of
At the same time, the data at the cursor position is written to the cursor register CR, and each time a character key is input, 1 is written to the data stored in the cursor register CR.
is added and incremented, data buffer memory
Move characters stored in DBUF to cursor register CR
are sequentially displayed at positions on the CRT display screen according to the stored contents.

On the other hand, regarding the framework processing process, according to the flowchart shown in Figure 5, first, in step S1,
Find the minimum and maximum values of line numbers among the framework data entered by key input, and calculate the minimum value of each line number.
Set RMIN and row maximum value RMAX and write to random access memory RAM. Next, in step S2, among the framework data by key input,
The minimum value and maximum value of the digit number are determined, and the minimum digit value CMIN and maximum digit value CMAX are respectively set and similarly written to the random access memory RAM.
Next, in step S3, the row minimum value RMIN is set as the row counter I and the random access memory is
Write to RAM. Next, in step S4, it is determined whether the line counter I and the input line number match or do not match, and if they match, the step
At S5, the coordinate position (I,
The indentation code is stored in the data buffer memory DBUF address corresponding to (I, CMAX) from (CMIN) to (I, CMAX). If the row counter I and the input row number do not match in step S4, the data buffer memory DBUF corresponding to the coordinate position (I, input digit number) on the CRT display screen is stored in step S6. Stores indentation codes sequentially in addresses.

When the data processing in step S5 or step S6 described above is completed, in step S7,
Row counter I in random access memory RAM
is incremented by 1, and then in step S8, as a result of the increment, the row counter I reaches the maximum row value.
Determine whether RMAX has been exceeded and set the row counter I
If exceeds the row maximum value RMAX, it means that all indentation codes have been stored in the data buffer memory DBUF, and if it is smaller than or equal to the row maximum value RMAX, the process returns to step S4 and stores the rows described above. Data processing regarding counter I is performed repeatedly.

Through the above processing steps, all the indentation codes necessary for configuring the framework are stored in the data buffer memory DBUF at predetermined addresses, and at the same time,
The images are sequentially displayed at predetermined coordinate positions on the CRT display screen, and the required framework is displayed.

In the configuration example of the character processing device of the present invention described above, the configuration of the display surface is 16 characters horizontally and 10 lines vertically, but it is of course possible to implement the present invention in the same manner even if such a configuration is changed. In addition, although the frame on the display screen is constructed using indentation, it can also be constructed using other characters, such as numbers and alphabetic characters.

As is clear from the above description, according to the present invention, coordinate data corresponding to line numbers and digit numbers is used when forming a framework used for character string editing etc. on the display screen of a character processing device. A predetermined frame can be easily and quickly displayed as needed by a simple key operation of inputting and memorizing the frame key and then pressing the frame key.

[Effects of the Invention] According to the present invention, by inputting the positions of rows and columns in which a framework is formed in numerical form, pattern information indicating the framework of the rows and columns is generated based on those numerical values. Ru. By displaying this pattern information, the operator can easily and reliably know the position and size of the set framework.
