Abstract

PURPOSE:To select the quantity of information to be deleted in accordance with the purpose of deletion and to reduce the operating quantity, by selecting automatically the contents of word deleting function in response to the ON/OFF state of a set character input mode and then executing the selected contents. CONSTITUTION:An insertion flag register in a RAM3 is set or not in response to the ON/OFF state of a set known character input mode, e.g., an insertion mode. Then an editing job is carried out in an insertion mode. In this case, a space serving as the word punctuation is left. Then this space is also deleted in case the editing job is carried out in an insertion OFF mode, and the contents of a word deleting function are selected automatically and executed. Thus automatic processing is possible in response to the editing purpose and based on the character input mode set by an operator.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field: The present invention relates to a text processing device that is equipped with a means for collectively deleting text information from a specified position of input text information to a specific character position.

[Prior Art] Conventionally, in this type of text processing device, a function for deleting character strings in units of words, that is, a word delete function, has been used to delete characters at once at spaces that separate words or at specific characters (for example, commas: ",", etc.). For the enclosed string, you can either delete everything from the current cursor position up to a space or a specific character detected after that, or delete all the characters up to the space or a specific character. It only had a character string deletion Ia function that could be used to delete strings. Generally, there are two purposes for using word delete: The first is to simply delete the specified word, and the second is to use it as part of the process of replacing the specified word with another word.

However, with a device having only a word delete function that allows only one of the above methods, it is not possible to simultaneously satisfy both purposes.

For example, according to the word delete function that deletes from the current cursor position to just before the space, if you delete from the beginning of the specified word to just before the space,
After deletion, two consecutive spaces remain before and after the deleted word, so if the purpose is only to delete a word, it is necessary to delete one of the remaining spaces, and extra operations are unavoidable. On the other hand, according to the word delete function that deletes from the current cursor position to the position including spaces, if you delete from the beginning of the specified word to the space, only one space will remain after deletion.

If you want to replace a word, even if you enter a new word using insert mode, which inserts a string at the current cursor position, you will need to enter an additional space at the end to separate the words. This was extremely inconvenient.

[Purpose] The present invention has been made in view of the drawbacks of the above-mentioned prior art, and its purpose is to delete information from a designated position of text information to a specific position in bulk for the purpose of deletion. To provide an easy-to-use text processing device that allows the amount of information to be deleted to be selected accordingly and reduces the amount of operations.

"Embodiment" Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

In the figure, reference numeral 1 denotes a central processing unit (hereinafter referred to as CPU) which is in charge of the main control of this embodiment, and which controls each component connected to each other, which will be described later, via a system bus 11. . 2 is CPU
A read-only memory (ROM) is used as a control memory for storing processing procedures of I, and a random access memory (RAM) is used as a work memory for temporarily storing ants, programs, and various data. 4 is a CRT for displaying data such as sentences and specifying character processing positions with a cursor; 5 is an external memory (hereinafter referred to as FD) for storing and storing created/edited sentences; 6 is a keyboard (
Hereinafter referred to as KB), various keys for giving instructions to the CPU 1 are arranged. 7 is a VRAM that holds display data to be displayed on the CRT 4; 8 is a CRT controller (hereinafter referred to as CRTC) that controls the display of the CRT 4; 9
is the FD5 file device (hereinafter referred to as FDC), and 10 is the keyboard controller (hereinafter referred to as KH2) that controls the KH2.
(referred to as B).

Next, an example of the configuration inside the RAM 3 is shown in FIG.

31 in Figure 2 is the insert mode flag register (IN
This is an area that holds the ON/OFF status of the insert mode input from the keyboard as a character input mode flag register. 32 indicates a dext buffer (DB), which serves as a storage area for one sentence.
It is a continuous buffer that has a storage area for 252 characters, and each area can store a character code for one character, and each area is assigned an address number from [0] to [251]. And D.B.
32 positions are specified using the buffer position cursor register (DB
-PO3I) 33, which corresponds to the cursor position displayed on the CRT4. 34 is a work register group (WK) for various temporary use areas;
34 holds the number of characters to be deleted (or deleted)
NT register 34a, buffer position cursor register 3
3 work area PO3I register 34b is included.

The operation of this embodiment having the above configuration will be explained below.

In this embodiment, text information is sequentially input from KH2 under the control of the CPUI, and this input text information is temporarily stored in RAM 3, displayed on CRT 4, edited here, and then recorded on FD 5. Ru. The configuration is such that two modes, insert mode and insert off mode, can be selected and specified as input modes from this KH2, and when insert mode is specified, an insert mode flag register is set.

Here, insert mode is used in text editing processing.
It is a character input mode that inserts a new input character at the cursor position in the text, and insert off mode does not insert the character but sequentially replaces and overwrites the character at the cursor position with the newly input character. You are in character input mode. This mode is arbitrarily set by inputting a function key (not shown) on the KBS.

Next, a more detailed explanation will be given using a flowchart.

FIG. 883 (A) shows general editing processing in this embodiment. At Sl, the CPU imports the key information input from KH2, and when the input key information is imported here, it is determined at 52 whether the general character key is manually operated or the function key is manually operated.If the input key is a general character key, the process proceeds to 531. , processes such as displaying characters corresponding to the keys input on the CRT 4 are performed, and in the case of a function key, a function process corresponding to the key manual input is performed in S4, and the lI heat collection process is completed.

Details of the special processing in S4 are shown in FIG. 3 CB).

First, it is checked in S5 whether the input function key is the insert ON key or not, and if the insert ON key is manually operated, the insert mode flag register (described later) in the RAM 5 is set in S6 and the process returns. If the insert ON key is not input in S5, the process advances to S7 to check whether the word delete key was manually input. Here, if the word delete key is manually operated, the process advances to step S8, executes word delete processing, and returns. If the word delete key is not pressed manually in S7, the process returns after executing the process corresponding to the input function key in S9.

Next, details of the word delete process in step S8 will be explained with reference to the flowchart of FIG.

To execute the word delete process, 1. Set the cursor on the CRT 4 to the beginning position of the word to be deleted using the cursor movement keys on the KBS, and then press and input the delete key.

An example of display of the text information inputted from the KH 2 on the CRT 4 immediately before execution of the delete process is shown in FIG. 5(A), where 12 is a text format display line in this embodiment. Further, 13 is a cursor for specifying the position of a character on the display surface of the CRT 4. This cursor moves on the CRT 4 in response to input from a cursor movement key (not shown) on the KBG.

In FIG. 4, as an initial process in SIO, the CNT register 34a of the work register group 34 is set at '0°9.
and stores the contents of the buffer position cursor register 33 in the PO3I register 34b.
It is checked whether the contents of the text buff 2 buffer 32 position indicated by the OSI register 34b is the "'EOF" code indicating the end of the sentence. If it is the "EOF" code, the process advances to S19 and the "EOF" code is detected.
If it is not an F'" code, the process advances to S12. In S12, the position indicated by the POSI register 34b of the text buffer 32, that is, the cursor display position is "space."

It is determined whether it is a code, that is, whether it is a word break. Here, “If it is not a space°° code, S13
, the CNT register 34a is incremented by one to count up the number of characters to be deleted, the POSI register 34b is also incremented by one, the text buffer pointer is moved backward by one, and the process returns to Sll again.

512, if it is a “space’” code, it is 514
Then, it is checked whether the insert mode flag register 31 is set. S when set
15, in order to delete the space code at the relevant position, the CNT register 34a and the POSI register 34 are deleted.
b is incremented and the process proceeds to S16. If the insert mode flag register 31 is not set in step S14, the process directly proceeds to 516.

In S16, like Sll, the content at the text buff 2 buff 32 position indicated by the POSI register 34b is the end of the sentence''
Check whether it is an "EOF" code, and if it is an °°EOF barcode, proceed to S19, and if it is not an "E OF" code, it is 51.
Proceed to 7. In S17, PO3I of text buffer 32
The contents of register 34b position ([PO3I register]
- [CNT register]) position, increment the PO5I register 34b in the subsequent step 318, and return to step S16.
Return to In this way, the sequential text information ends.”E
OF” Go to the code position, and when it finishes to the end, advance to S l 6J: l, Is 19, S 19 TeP
"E" in the text buffer 32 indicated by the OSI register 34
OF" code is moved to the ([POS register]-[CNT register]) position, and the delete process is completed.

As a result, if the insert mode flag register 31 is not set when the cursor is at position 13 shown in FIG. 5(A), the result of the delete process shown in FIG. 4 is as shown in FIG. 5(B). 'delete' is deleted.

This may occur when the operator edits in insert-off mode, when the operator simply wishes to delete the word, or because the operator is editing with the aim of making major corrections to the text, leaving extra spaces that used to separate words. This stems from the idea that not only is this unnecessary, but it also gets in the way of editing.

The transition of text information within the text eightfolder 32 during this time is shown in FIGS. 6(A) and 6(B).

Initially, as shown in FIG. 6(A), the posx register 34b
The position is ``'d°'', and after the processing is completed it is as shown in Figure 6 (B
), 'delite ``next character'''0'' will be placed at the position initially indicated by the POSI register 34b.

If the insert mode flag register 31 is set, the text information in the state shown in FIG.
It is deleted leaving a "space" code as shown at 51 in Figure (C).

When an operator edits in insert mode, it is thought that the purpose of editing is to insert the string again at the cursor position after deletion, such as by using word delete in the process of replacing the word with another word. By leaving a space as a delimiter between words that already exist when deleting, there is no need to enter a space again even if a character string is inserted at the corresponding position after deletion.

Therefore, if you want to input a new character string, for example, ``abc'' at the deleted position, you only need to input the 3-character code ``abc''. Figure 5 (C )52.

In the above explanation, we explained the word delete function that deletes up to the ``space'' code inserted as a word delimiter, but it also deletes character codes from the position specified by the cursor to specific character codes other than the ``space'' code. The word delete process for collectively deleting up to this specific character code, which may be controlled to be deleted all at once, will be explained with reference to the flowchart of FIG.

These specific characters include °, ” (comma), ”,
゛ (period), 16. Any character such as II (colon) can be specified. This can be done by providing a specific code reference table in RAM 3 that indicates the specific character character indicating the position to be deleted, and deleting from the specified deletion start position to the specific code stored here, or up to just before the specific code. .

An example of the configuration of the RAM 3 in this case is shown in FIG.

In FIG. 8, parts similar to those in FIG. 2 are given the same numbers, and their explanations will be omitted. 34C is a TB-PO5I register indicating the specified position of the specific code reference table, 35 is the above-mentioned specific code reference table,
TB [0] 35a.

TB [1135b-TB [nl 35n and TB-
Consists of END35E, TB-END35E
indicates the end position of the specific code reference table 35, specifically, the code "OO" is stored therein.

(7) TB [01~TB [n position specification is TB
- It is specified by the PO5I register 34c, and a specific code for distinguishing the above-mentioned deletion area may be stored here.

In the batch deletion process using the specific code reference table 35 shown in FIG. 7, the same steps as those shown in FIG. 4 are given the same step numbers.

Therefore, 512-1-, which is different from the case of 512 in FIG.
512-4 will be explained.

When Sll confirms that it is not "EOF", TB-POS l34c is set to "EOF" in Sll 2-1.
TB-PO5l in the 0th order 312-2 where the pointer of the reference table for the specific character is initialized as O''.
The contents of the text buffer 32 specified by 34b are TB-
Determine whether it is END35E or not, and if it is TB-END35E.

Since the corresponding character in the text buffer 32 does not exist in the specific code reference table 35, the process advances to 513.

On the other hand, if it is not the same as TB-END35E, 512-
3, it is determined whether the contents of the text buffer 32 position specified by TB-PO3I34ccF) match the contents of the text buffer 32 position specified by PO5l34b. If they do not match, 4tS12-4 (z'
TB-PO5l34b is incremented, and the processes 512-3 and 312-4 are sequentially executed regarding the contents of the specified position of the next specific code reference table 35+7) TB-PO3I34c. If there is a match at 512-3, the process advances to 514 and the same processing as in FIG. 4 is performed.

In the process shown in FIG. 7, the specific code reference table 35

) when the 0 text information shown in ) is being input, the cursor is 9
For example, if the word delete key is input at position 1, if the insert mode flag register 31 is not set, the separator word "2" is input as shown in Figure 9 (CB). ' will be deleted all at once.

In addition, if the insert mode flag register 31 is set, if the text is deleted all at once, the text before the ":" will be erased as shown in FIG. 9(C) 92.
" will be deleted and : " will remain. Therefore, if you continue to input "abc" from KH2, the
As shown in FIG. 3, desired text information can be obtained with the minimum necessary operation input processing.

[Effect] As explained above, according to the present invention, the well-known character input mode that is set, for example, the insert mode is turned on,
By automatically selecting and executing the word delete function according to OFF, etc., it is possible to realize automatic processing according to the editing purpose based on the operator's character input mode setting, improving operability. At the same time, it is possible to provide a text processing device that enables efficient editing.
