Description

[Detailed Description of the Invention] (A) Technical Field of the Invention The present invention enables commands for giving various commands to a document processing device, particularly a system, to be created in text in the same way as normal document text.
The present invention relates to a document creation processing device that can efficiently input and execute commands.

(B) Prior Art and Problems Generally, in a document creation processing device, a document is created by inputting document data from a keyboard and displaying the document data on a display screen. For example, commands for document editing such as "insert", "delete", "line feed", etc. are usually given to the system by dedicated function keys provided on the keyboard. However, for slightly more complex or less frequently used commands, such as bringing the current screen to the final position of the text, or extracting a certain part of another file and embedding it in the current text, Since it is not possible to assign a function key to each command, the content of the instruction to the system is notified by a command using a predetermined character string as a keyword.

FIG. 1 shows a diagram explaining the problems of the conventional method. In the figure, 1 is the display screen, 2 is the text screen, 3 is the data cursor, 4 is the command line,
5 represents a command cursor.

Conventionally, in a document creation processing device capable of inputting commands, an area for a text screen 2 and an area for a command line 4 are provided separately, for example as shown in FIG. This was done by keying in the position. Note that the cursors such as the data cursor 3 and the command cursor 5 indicate the character position to be operated next on the screen, and the character position is hereinafter referred to as the current digit.

According to the conventional method described above, when inputting a command, it is necessary to move the cursor or line of sight, and a fixed sequence of commands cannot be generated in advance, so there is a problem that the operability is not sufficient. .

(C) Object and Structure of the Invention The present invention aims to solve the above-mentioned problems, eliminates the need to provide a text screen and a command line separately, and allows command sentences that are originally handled conversationally to be processed normally through a text processing mechanism. It is an object of the present invention to provide a document creation processing device that can create a document text in the same way as a document text, and can realize programming, text conversion, storage stability, standardization, etc. of a group of command sentences. Therefore, the document processing device of the present invention is a document processing device that is equipped with a display and a keyboard, processes document text, and inputs and executes commands that give various instructions regarding document processing to the system. Command extraction by providing a command/enter key on the keyboard and extracting a command statement from the text area corresponding to the current line including the cursor position indicating the current digit on the display screen by pressing the command/enter key. a decoding unit that interprets the command statement extracted by the command extraction unit; a command execution unit that is activated by the decoding unit and executes instructions according to the contents of the command statement; The present invention is characterized in that it includes at least a command erasing section for erasing the command statement from the text area if it does not exist, and performs command processing by introducing a command text line. Hereinafter, embodiments will be described with reference to the drawings.

(D) Embodiments of the invention Figure 2 is an explanatory diagram of the processing concept according to the present invention, Figure 3
The figure shows the configuration of an embodiment of the present invention, FIG. 4 is an explanatory diagram of a processing mode of an embodiment of the invention, and FIG. 5 is a diagram illustrating a processing operation of an embodiment of the invention.

In FIG. 2, numerals 1 to 3 correspond to those in FIG. 1, 6 is a keyboard, 7 is a command enter key, 8-1 and 8-2 are command lines, 9
represents the current line.

In the case of the present invention, on the display screen 1 of the display,
Although a text screen 2 is provided, there is no need to provide a command line separately from this text screen 2. In other words, command lines such as illustrated command lines 8-1, 8-2, etc. are optionally incorporated into the text. In other words, command statement generation is performed using document generation functions (line feed, deletion, copying, etc.) without any distinction from normal document data input. In fact, it is just text before it is passed as a command. On the other hand, the keyboard 6 is provided with a command enter key 7, which is a dedicated function key for passing a command line in a document text to the system.
For example, when requesting the system to execute the command on the command line 8-1 on the display screen 1 shown in FIG. match. The character position of cursor 3 is the current digit, and the line where the current digit is located is current line 9. When the command enter key 7 is pressed here, the system determines that the text string on the current line is a command line. Then, analyze command line 8-1, and if there is an error, screen 1
Displays an error message at the edge of the
The state is restored to the state before the enter key 7 was pressed. If the command is correct and its execution ends normally, the command line 8-1, which is currently on line 9, is deleted from the text. That is, the display screen 1 is
For example, it will be as shown in FIG. 2(b). Of course, if the command line 8-1 instructs to extract and insert some document data from another file into the current line 9, for example, the document text in the inserted form will be , will be displayed.

In other words, the present invention, in document editing operations,
This is a system that generates meaningless document data and a command statement, which can be called a command for editing the document, and allows the command to be executed at any time. It can be said that it incorporates ideas that were not present in previous document processing devices. Furthermore, after a command is executed, the command statement is automatically deleted from the text, so no unnecessary operations are required when printing out the document. In addition, on the command line,
It is not necessarily necessary that only command statements exist, and normal document data may also be included. This is because when analyzing a command, it is easy to distinguish between normal document data on the current line and the command statement, and it is possible to leave the document data and delete only the command statement after execution is complete.

FIG. 3 shows the configuration of an embodiment of the present invention.
In the figure, numerals 6 and 7 correspond to those in FIG. 2, 10 is a display, 11 is a screen memory, 12 is a screen control section, 13 is a window register, 14 is a cursor control section, 15 is a cursor register, and 16 is a Paper memory, 17 a display window, 18 a keyboard control section, 19 a command processing section, 20 a command extraction section, 21 a decoding section, 22 an error processing section,
23 is a command erasing section, 24 is a command execution section,
25 represents a text editing section, and 26 represents an external storage device.

The screen memory 11 is a memory in which code information displayed on the display 10 is stored. The paper memory 16 is a memory equivalent to the paper used by humans when writing, and is a memory that holds the contents of the text currently being created or the text read from an external storage device 26 such as a flexible disk. . Display 10 is generally not large enough to display the entire space of paper memory 16. Therefore, conceptually, Display 10
A display window 17 corresponding to the size of the display screen is set, and the contents of the paper memory 16 are cut out by the display window 17 and transferred to the screen memory 11. This control is performed by the screen control section 12. Window
The register 13 holds the address of the display window 17 in the paper memory 16. By updating the contents of the window register 13, the position of the display window 17 can be moved and the display screen can be scrolled.

The cursor control unit 14 maintains a cursor register 15 in which position information of a cursor in the screen memory 11 is stored. This controls the movement to the right by one character. The keyboard control unit 18 controls the keyboard 6 and, for example, inputs commands and
When the enter key 7 is pressed, it is detected and the command processing section 19 is called.

The command extraction unit 20 of the command processing unit 19
A command statement is extracted from the current line in the display window 17. The extracted command sentence is transmitted to the decoding unit 21. The decoding section 21 checks command sentences and analyzes them. If the contents of the command statement are correct, the command execution unit 24 corresponding to the command is activated. If there is an error in the command statement, error handling section 2
Call 2. The error processing unit 22 transfers error information to the screen memory 11 and notifies the operator of command errors. For example, error
By inputting the message release key, processing is also executed to completely return the screen to the state immediately before the command/enter key was pressed.

The command deletion section 23 deletes the command sentence extracted by the command extraction section 20 from the paper memory 16 when the command execution section 24 starts or ends execution. In the deleted portion, character filling or line filling is performed after taking into account the line feed control code.

The command execution section 24 executes various commands, and the text editing section 25 inputs character keys and general function key information and stores them in the paper memory 1.
6 to create and edit document text, etc. These can be considered to be the same as before.

Next, a processing mode of an embodiment of the present invention will be explained with reference to FIG.

For example, suppose that a document as shown in FIG. 4A is currently being handled. The contents of the paper memory 16 cut out by the display window 17 are displayed on the display screen. For example, a scroll key is used to move the display window 17, and a cursor movement key is used to move the cursor 3. When the 1 line generation key on the keyboard is pressed in the state shown in FIG. 4A, a new blank line 30 is generated next to the current line, resulting in the state shown in FIG. 4B. That is, the position of the display window 17 is moved down one line in the paper memory 16. Additionally, the entire text content starting from the line following the current line is moved down by one line, and the last line of the paper space in the paper memory 16 is erased. however,
If the last line is not a blank line, a warning is issued in advance. Then, the line left vacant by the above movement is filled with a blank code, making it a blank line. The current digit moves to the leftmost digit and is set to the first character of the current line, which is a new blank line 30.

If you enter a character key here, the required text line will be added using normal text editing and creation functions. The creation of this text line is handled in the same way, without distinguishing between document data and command statements. In this example, a command statement for a macro text calling command (% command) is input. The macro text calling command consists of a macro text name and an arbitrary number of parameter substitution values, as shown in FIG. 4C, for example.
A pre-registered macro text 31 is called up when a command is executed and added to the current line. The parameter substitution value replaces a variable item (for example, &) in the macro text 31.

If a command statement is input as a text line and another line of the same command statement is required, the text line of the command statement can be duplicated with one touch using the current line copy key, for example. Can be done. FIG. 4D shows the state of replication. In other words, the current line duplication key generates a new line below the current line and copies the same data as the current line to that line, but after execution, the current line and current column do not move on the screen. This is an instruction to do. In this way, command sentences can be efficiently created using various text editing processing functions, just like normal document data.

In the state shown in Figure 4D, press the command Enter button.
Suppose a key is pressed. The text of the current line where the cursor 3 is located is retrieved from the paper memory 16,
The command statement is analyzed and if it is correct, the command is executed. In this example, the command statement indicates a macro text invocation command, so "DO"
The macro text 31 with the name is called and macro expansion is performed. At this time, the parameter substitution value ABC is set as a variable item. After the command is executed, the command statement on the current line is deleted from the text, so the display window 17 becomes as shown in FIG. 4E.

If the command enter key is pressed and the command statement is analyzed and an error is detected, an error message 32 will be displayed on a portion of the display screen, for example as shown in FIG. Ru. After confirmation, if the error message is canceled using the error message cancellation key, the screen is restored to the state before the input of the command enter key, that is, the state shown in the display window 17 of FIG. 4D. After this, all you have to do is remove the cause of the error and press the command/enter key again.

From the state shown in Figure 4E, for example, move the cursor 3 down two lines, and
ABC can be changed as necessary and macro expansion processing can be executed in the same way.

As can be seen from Figure 4, the current line hardly moves, so it is necessary to move the line of sight to the command line area fixedly provided at the bottom of the screen every time a command statement is input, as in the conventional method. If there is no error, you can easily modify the command statement and re-enter it.

Next, the processing operation of one embodiment of the present invention will be briefly explained with reference to FIG. When a key is entered,
First, in the process 40 shown in FIG. 5, it is determined whether the key is a command enter key. If the input key is not a command/enter key, the input key information is notified to the text editing department or the like. command·
If it is the enter key, the process moves to step 41, where the address of the corresponding paper memory is determined from the current digit at that time. Next, in process 42, the current line is read, and in process 43, a command statement is extracted. The extracted command sentence is subjected to command analysis in process 44.
If there is an error, the process 47 is notified, and if the format is correct, the command is executed by the process 45. Again, if there is an error, the process 47 is notified, but after the command is executed, everything may be treated as normal. If it is normal, remove the command statement in the text, pad it as necessary,
Fills the line and returns to the key input waiting state. If an error is detected during command analysis or the like, an error message is displayed in step 47. Then, for example, using the input of the error message release key as a trigger, the screen is restored to the state before the key input in process 48.

(E) Effects of the Invention As explained above, according to the present invention, the text editing and creation function of the system can be fully utilized when generating command sentences. On the system side, on the other hand, by abolishing fixed command lines, there is no need to support special processing for generating command statements. Since a group of command lines can be saved and edited as text, standard sequences of commands can be easily generated and executed through a text macro processing mechanism. Since the command line is handled near the current input point, there is no need to move the cursor or line of sight between the command line and the specially provided command line, which is required in the past, improving operability.
