Abstract

PURPOSE:To increase the number of characters by one character arranged on each line when no space is able to afford, by discriminating the presence/absence of the space just before a symbol representing the end of each line, in inserting a character string to each line of a prescribed range in a document. CONSTITUTION:A character pattern signal from a character generator 10 is processed according to a display control signal in a display controller 9 and the processed character pattern signal is applied and displayed on a CRT display 8. Further, the character generator 10 outputs a character pattern to be arranged on a line designated with a code input among character patterns stored sequentially and a refresh memory 11 outputs the character code and display control code repetitively in response to the command of the display from the CRT controller 7. The controller 12 controls the data write and readout from a microprocesor 1 and the refresh cycle of the CRT display in response to the command from the CRT controller 7.

Description

[Detailed Description of the Invention] Regarding a character processing device that adds l characters to each position in the same column of each line in a required range, the character processing device adds one character to each position in the same column of each line in a required range, and in particular, depending on the presence or absence of a space immediately before the symbol indicating the end of each line, by a simple operation, It is possible to add character strings without changing much the manner in which character groups are arranged in rows and columns.

Conventionally, in this character processing device, when inserting the same character in the direction of the row K [Q] in which characters are arranged in a created document, for example, only for each row in a certain range in the created document. When inserting the same character for l characters at a time (move and insert characters for each line) Since there will be a shift in the character position for each
It was necessary to increase the number of characters arranged in each line. Also, the string [Even if you insert it, for each line in the predetermined range,
Since the number of character arrays on each line increases all the time, the character array of the entire document has to be changed.

The object of the present invention is to eliminate the above-mentioned drawbacks of the conventional technology.

If you want to insert a character string in each line of a predetermined range of the created sentence i in row 5, you can use a character processing device that can insert character strings with simple key operations without changing the character arrangement of the entire document. It is about providing.

In other words, when inserting a character string into each line in a predetermined range of a document, the character processing device of the present invention inserts a character string into each line only when there is no space, depending on the presence or absence of a space immediately before the symbol at the end of each line. K is added to increase the number of characters in the array by one character.

The present invention will be described below with reference to the drawings.

The character pattern f to be arranged in the line specified by the character pattern row addon etc. is sequentially output and sent to the 7-lens memory//lx: C) LT display x7-ray device rK Character code and display control code to be displayed is stored once, and then those character codes and display control codes are stored in 4# according to display instructions from the CRT controller 7.
I'll come back. Furthermore, the Refrenz 5-memory controller 12, in response to instructions from the CIL'l' controller 7, carries out the above-mentioned processes for CRT display, and the dissemination and continuous output of data from the Microprocessor Center t/. and control. Note that /J is a read-only memory, which is a so-called read-only memory, and stores control procedures for character processing, which will be described later, as well as various processing procedures.

It is a controller for the IL-only memory 13, and /j is a fundam access memory that temporarily stores various data. Prior application address memory 8B temporarily stores the start address of 81B, line number input for counting the number of lines of the created document [cursor start register CU8 for counting, cursor pointer CUP, cursor end register CUIB, /ffK array] Register for storing the maximum number of characters that can be obtained l1 Code register for temporarily storing codes of characters and symbols uU, GYIi, GY
I, an input data memory MOJ for temporarily storing 17 characters of the signal input from the keyboard J, a blank address register 8P for temporarily storing the position of the code, etc. are provided. In addition, /4 is this fundam access memory /
This is the controller for S.

Next, an example of a specific configuration and arrangement of the keyboard I is shown in FIG. In the illustrated configuration, %fA is a group of character and symbol keys consisting of an alphapect key, a katakana key, a hiragana key, various symbol keys, etc., and a group of cursor movement keys for instructing the movement of jBf écarnaire in up, down, left, and right directions. , and IC is a range key that specifies the range of character insertion.

! D is inserting -, which indicates the insertion of a character, and furthermore!
l is the space key.

Next, FIG. 3 shows an example of a flowchart representing the manner of character string insertion operation into a document by the character processing apparatus of the present invention. In the illustrated flowchart.

First, the keyboard! To create a document consisting of a table as shown in Figure 1 using key operations, and insert a space pattern into the table, press the insertion range key jC on the keyboard j with the stencil 829, Next, in step 8J, the cursor start register CU! in the random access memory IS is read. i.

Cursor pointer CUP K Stores the address where the cursor is located, and sets the cursor at the position of the last line in the column where one character string is to be inserted, as shown in FIG. Next, go to step 8 and step 7182.
Press the insertion range key Ic in the same way as in , and then,
At step Ill, the cursor end V register CU in the random access memory IS is
Keyboard space pattern to be inserted after storing the address to be located! Input by pressing the space key SF above. Next, in step 86K, the column insertion key jEt- on the keyboard j is pressed to insert the character string entered by pressing the space key II, and then, in step 87, random access memory 1 is pressed.
The space code input by pressing the space key jl is stored in the input data memory MOJ in 5. next[
, at step St.

Check whether the addresses stored in steps 18J and 81 are located in the same vertical column. If they are not located in the same column and C, return to step 7181 and check whether the addresses stored in steps 18J and 81 are located in the same column. If the
Regarding the cursor address stored in steps S3 and 85K, it is determined whether the value stored in the cursor start register CUB K is smaller than the value stored in the cursor start register CUB K, and if it is not smaller [4]
Stay 78/K return, if small, move to step stoK.

The character codes corresponding to the row start position pattern 17 and row end position pattern /IK shown in FIG. Line count register SU'f: OK is set, and the value of the maximum number of characters that can be arranged in one line is stored in register 11K in random access memory IS, and the character code corresponding to the blank pattern code is stored in code register HAKU. Store. Next, step 8
// Use K to determine whether the column to which the character string should be inserted is a column that has the row start position pattern /7 t-stored, and whether it is a column that has the row start position pattern /7 t-stored or not. For example, the process returns to step 81 and stores the rja start position pattern/7 in the first row.If the column is not a certain column, fc moves to step 81J. Next, in steps 81 and 8/J, it is determined whether the row final position pattern II is stored at the address next to the address in the Kahnle pointer CUP, and if it is not stored, % It is determined whether or not it is stored at the next address, and the final position pattern/Irt of one row is stored at the address [heading page]. Next, step 718141K determines whether or not a blank pattern code is stored in the address before the row final position pattern /I.
If the code stored at that address is not a blank pattern code, move the code of the row final position pattern /l by increasing it by 21 minutes from the address stored at that time, and then step stt rc
Subroutine for inserting strings [# line].

Also, .

If it is a blank pattern board in step 81, proceed to step 816K, store the address at that time in the address next to the address in the blank address register 8P, and repeat the same operation for the next line. To do this, the row number count register 8U in the random access memory 1S is incremented, and the value in the Kahnlevo inter CUP is reset to i[K cents in the Kahnlevo start register Cυ8. Next step 8/7 Vc? , the value in the Kahn Lebo inter CUP, the value in the register E that stores the maximum number of characters that can be arranged in one line, and the value in the line count register sU [multiplyed] are added, and in the first row,
The value in the Kahn Lester register CUa of the row at that time and the address of the fourth column are set as the values in the new Kahn Lester pointer CUP. Next, the value in the Kahn le pointer CUP obtained in step 8/7 is the value in the Kahn le point register CU
It is determined in step 778/r whether or not the value in E is greater than the value in CUI? If the value within is larger, the process moves to step 819 and the blank address V
Step 8/4C to step 811 are repeated by incrementing the value in register sP,
If the value in the Kernle pointer CUP becomes larger than the value in the Kernle pointer CUP, rc moves to step 8λO, and the input data memory MO is updated for the row included in the addresses of the Kernle start register CU8 and the Kernle end register CUB.
Insert the data in J as a vertical character string. Next K
.

In step 778J/, after inserting a vertical character string in step 8 OT/C, the contents of the address in the line end position pattern/l are stored in the line containing the address in the carn end register CUN. The space code K11 is converted by setting the value in the code register Hffl in the dumb access memory IS. In addition, the address where the code for the 1st line final position pattern /l was stored before inserting the vertical character string in step 820 VC, that is, the address that was replaced with the blank pattern code in step S. By setting the contents of the previous address to the value in the code register GYE in the random access memory lj, it becomes the code for the row final position pattern it.

Next, step 8 - Stemp S KojK Oi ℃.

By subtracting the value in the blank address register sP, the same operation as described above is repeated up to the line containing the address in the Kahn Luster register CUa.
As shown in the figure, the operation of inserting a VC1 character string [Complete].

As is clear from the above explanation, in the character processing device of the present invention, ck':L is used to specify a line in which a character string is to be inserted, and for the specified line, the pattern preceding the pattern indicating the final position of the line is By determining whether or not it is a blank code pattern that is not related to the creation, the maximum number of characters that can be arranged in one line [Determine whether or not to change it by simple key operations.

Moreover, it is possible to insert one character string without having to make many changes to the entire document.

In addition, if you want to delete one character string many times on the same line in the same way as above, once you specify the address in Kaanl, simply press the insert key as many times as you like. Of course, character strings can be continuously reduced.

In addition, the above explanation about the case where the range of lines where one character string is inserted is /@ place [I did this, but if you use 4c or more kernels, you can use the above explanation for the line range of 4 or more places that do not overlap with each other. You can perform character processing similar to .
