Abstract

PURPOSE:To edit a token which is frequently used within a file with a simple operation by providing a history menu or/and a reserved word menu into a RAM and then displaying a pop-up menu on a CRT screen based on the history and reserved word menus. CONSTITUTION:A file stored in an external memory 2 is loaded to a random access memory (RAM) 3 via an I/O bus 7. Then the file loaded in the RAM 3 is totally or partly displayed on the screen of a CRT 4 via the bus 7. At the same time, the character data, etc., inputted through a keyboard 5 are also displayed on the CRT 4. Thus it is just required to point an optional token displayed on a pop-up menu shown on the CRT screen in case an editing process is carried out to put an inputted token into the file. As a result, a character string which is frequently used and a code train having a meaning can be edited in the file with a simple operation.

Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to an editing device with a history function, and in particular allows frequently used character strings (rows and columns) to be edited in a file with simple operations. This invention relates to an editing device with a history function.

(Conventional technology) Conventional file editors use input character strings (documents, etc.)
If you want to use a meaningful code string (program source, etc.) again, you have to copy the string or code string that you previously created manually. Note that, hereinafter, the character string and code string will be collectively referred to as galvanized iron.

For example, when creating a character string by operating the character keys on the keyboard, enter the same character string as the previously created character string (for example, a short sentence) following the current character string. In the past, when you wanted to do this, you would display the string you created on the chain on the screen, specify the range of string you wanted to use, and use the copy function to copy it after the string you were currently creating.

If the character string you want to copy is not on the same screen, display the previous or next page on the screen, display the desired character string on that screen, and use the same operation as above to copy the desired character string. The character string was copied to the location.

(Problem to be Solved by the Invention) As described above, conventionally, when you want to reuse a previously input token, you have to select the previously input token with a cursor and then specify the location where you want to copy it. However, there was a problem that the operation was troublesome.

In particular, if the token you want to copy is not on the same screen, display the page that contains the desired character string on the screen, select the desired token, and select the page where the location you want to copy exists. There was a problem in that the user had to specify the location to copy by displaying it on the screen, which made the operation very troublesome.

The purpose of the present invention is to eliminate the problems of the conventional device described above,
To provide a device that allows frequently used tokens to be edited in a file with a simple operation.

(Means and Effects for Solving the Problems) In order to achieve the above object, the present invention provides a history table for storing input tokens, and a predetermined number of tokens in the history table. means for displaying on a screen; and means for displaying an I on a screen of the CRT;
- It is characterized in that it is equipped with a means for specifying an arbitrary one, and a means for inserting the specified tin into a file.

According to the present invention, when editing the file to insert a previously input token, the token is inserted into the file by pointing to an arbitrary token displayed in a pop-up menu on the screen of the CRT. can be inserted into a predetermined position.

Therefore, frequently used character strings and meaningful code strings can be edited in files with simple operations.

(Example) The present invention will be described in detail below with reference to the drawings.

FIG. 2 shows a system configuration diagram used in the present invention.

1 is a CPU that controls the following devices. 2 is an external storage device for storing documents and various source files, such as a hard disk or a floppy disk. Reference numeral 3 denotes an internal storage device, such as a RAM, which stores files to be actually edited. 4 is a CRT having a screen for displaying the contents of the RAM 3; 5 and 6 are a keyboard and an auxiliary input device for inputting editing contents, respectively;
For example, a mouse). Further, 7 is an I10 bus for transmitting data between the respective devices.

In the above device, the file editing procedure is performed as follows. Files stored in the external storage device 2 are loaded into the RAM 3 via the I10 bus 7. The entire file or a part of the file loaded into the RAM 3 is transferred to the screen on the CRT 4 via the I10 bus 7.
will be displayed.

Further, character data etc. input from the keyboard 5 are also displayed on the screen on the CRTJ.

FIG. 3 shows an example of the screen display of the CRT 4 J: and a conceptual diagram of the history table formed in the RAM 3 J-.

4a in FIG. 3 is an edit file displayed on the screen, 4b is a pop-up menu to be described in detail later, and 9 is a cursor indicating the next editing point. 10 shows a history table created on RAM 3 according to the present invention. In the history table 10,
Tokens input by the file editor from the keyboard 5 are stored in sequence. Are the units memorized different?
It is stored as a unit when a file editor inputs the line feed key, or when a Japanese editor performs kanji conversion. Since the history table 10 has a finite capacity, when it becomes full, the first stored token will be erased, and a newly manually created token will be stored in the erased area.

Here, specific examples of the history table 10 and some pointers that control it will be explained in detail.

Normally, such a history table 10 manages the start address of an area in which tokens are stored. However, in order to simplify the explanation, we will use the history table 1
One box within 0 (10a, 10b, 10c, etc. in Figure 3)
shall be able to store tokens of sufficient length.

Further, it is assumed that the number of tokens that can be stored in the history table 10 and the number of tokens that can be displayed on the n1 pop-up menu 4b is m.

Here, three pointers, ie, a display pointer, a token addition pointer, and a token indication pointer, are defined as follows.

-Display pointer This pointer is a pointer for managing 1 to -kun to be displayed on the pop-up menu 4b. Specifically, m tokens from this display pointer are displayed on the pop-up menu 4b.

If the value of (display pointer 10 m) exceeds n, it is displayed so that the sum of the nth number of tokens and the number of tokens from the beginning of the history table 10 becomes m.

- Token addition pointer This pointer is a pointer that manages the addition of input tokens to the history table 10. The token addition pointer is normally updated by adding 1, but if the pointer exceeds n, this pointer is returned to 1, that is, to the beginning of the table 10.

As a result, the first token will be overwritten and deleted by the next addition.

-Token instruction pointer p1 This pointer p1 is a pointer for managing the token selected on the pop-up menu 4b. This pointer is normally updated based on the amount of mouse movement. Also, use this pointer or the top of pop-up menu 4b.
When the display pointer reaches the top or the bottom, the display pointer is updated.

Further, in order to identify the selected token, the token pointed to by this token indication pointer is displayed in reverse video on the pop-up menu 4b.

When the token designation pointer is updated, the reversed token returns to its original state.

Next, a functional block diagram of this embodiment is shown in FIG. In the figure, blocks corresponding to the hardware configuration in FIG. 2 are given the same reference numerals.

20 is a control device, 21 is a token addition pointer control means, 22 is a token instruction pointer control means, 23 is a display pointer control means, 24 is a history management table, and 25 is a document editing means.

The operation of sequentially storing character strings input by a file editor in the history management table 24 will be described with reference to FIGS. 1 and 4. FIG. 4 is a flowchart showing the token addition procedure.

When the file editor inputs a character string using the key manual device 5 shown in FIG.
The document then enters the document editing means 25 and is displayed on the document display device on the screen of the CRT 4. During the input of the character string, when a line feed key is pressed or, in the case of a Japanese editor, kanji conversion is performed, the control device 20 detects this and extracts a token (step Sl). When the token is extracted, the extracted token a is stored in the position pointed to by the token addition pointer pl on the history management table 24 (step S2).

Next, it is determined whether the token addition pointer p1 is equal to the number n of tokens that can be stored in the history table 10 (step S3), and if they are equal, the i-kun addition pointer p1 is equal to 1. (Step S4). In other words, the position pointed to by the token addition pointer p1 becomes the beginning of the history table 10. on the other hand,
When the token addition pointer p1 is not equal to n, 1 is added to the token addition pointer p1 (step S
5), the update is performed.

As described above, on the history management table 24,
A token is added.

Next, the operation of inserting a previously input token into a desired position on the screen of the CRT 4, ie, the position indicated by the cursor 9, will be explained with reference to FIGS. 1 and 5. FIG. 5 is a flowchart showing the token insertion procedure.

First, the file editor moves the cursor 9 to the key 5 on the human powered device.
Alternatively, when the user moves the token to a desired location using the mouse 6 or the like and presses a special key (for example, a mouse button), the control device 20 detects that there is an instruction to display a pop-up menu (step Sl). Next, the control device i\20 sends the display pointer update information to the display pointer control means 23 to update the display pointer. Specifically, it is set to a value obtained by subtracting m from the token addition pointer pl (step S2). Next, the control device 22
Update information of the token indication pointer is sent to the token indication pointer control means 22 to update the token indication pointer. Specifically, the token designation pointer is set to the same value as the display pointer (step S3). Next, move m tokens from the display pointer to the CRT4.
Display in the pop-up menu above (step S4
). At this time, the token pointed to by the token designation pointer is displayed in black and white or inverted (step S5).

When the initialization is completed as described above, the next step is to insert the corrugated iron. First, the control device 20 controls the mouse 6
A determination is made as to whether or not there was a movement (step S6).
), if this judgment is affirmative, update information of the indication pointer is sent to the token indication pointer control means 22. Then, the token indicating pointer control means 22 restores the highlighted token to its original state (step S7) and calculates the token indicating pointer from the movement of the mouse (step S8). Next, it is determined whether the token indication pointer is in the pop-up menu (step S9), and if the answer is yes, the process returns to step S5,
The token indicated by the token indicating pointer is displayed in reverse video. On the other hand, if the answer is negative, a process of calculating a new display pointer from the token indication pointer is performed (step 5).
10). That is, the pop-up menu is scrolled. After that, the process returns to step S4.

”Repeat the steps in step 1 as many times as necessary, step S.
If the result is 6 or negative, the token to be inserted has been selected.

Next, in step Sll, the control device 20 determines whether there is an insertion instruction. Specifically, the insertion instruction is given by the file editor or by pressing a special key or mouse button.

When there is an insertion instruction, insertion token information is sent from the control device 20 to the token instruction pointer control means 22, and insertion token selection information is sent to the history management table. As a result, the selected insertion token is inserted from the history management table into the position indicated by the cursor 9 via the document editing means 25. In this way, the token pointed to by the token indication pointer is inserted into the file being edited (step 512).

If the insertion instruction is not received or if there is an insertion instruction, the pop-up menu is deleted (step 513).
.

As shown in ``2'', according to this embodiment, after specifying the token insertion position of the file being edited with the cursor, the pop-up menu is displayed on the CRT screen. You can insert tokens by simply pointing the mouse at the required token in
It has the effect of allowing you to edit frequently used tokens with simple operations.

Especially when the token to be inserted is outside the edited file 4a displayed on the screen of the CRT 4, the effect is greater than in the conventional device.

In the above embodiment, the pop-up menu is displayed on the screen of the CRT 4 as necessary, but the present invention is not limited to this. Frequently used tokens may be displayed.

Moreover, the file to be edited is C language, PL=1, F
If it is a source file of a computer language such as ORTRAN, just like the history table above,
Create a reserved word table.

The reserved words are meaningful character strings prepared for the compiler (for example, in the C language, H, f'or, etc.).

5w1tch, whHe, etc.). When editing source files, using this history menu and reserved word menus significantly reduces the amount of key manual effort.

(Effects of the Invention) As described above, in the present invention, a history menu and/or a reserved word menu is provided in the RAM, and a pop-up menu row is displayed on the CRT screen based on this menu. This has the advantage that frequently used tokens can be edited in a file with simple operations.
