Abstract

PURPOSE:To efficiently execute numerical calculation processing in the middle of document processing even when a document includes a lot of numerical data by providing function for both character preparation and numerical calculation by moving a cursor which instructs a character input position in the document. CONSTITUTION:In a state 15 exclusive for character input, a character is inputted to a cursor position 17 and in a numerical calculation state 16, a numerical value is inputted and calculated in an window 18 for calculation. The function to exchange the numerical data between the two states 15 and 16 is realized by numerical data fetch function to fetch the numerical data from the position of the cursor 17 into the window 18 in the state 16 and numerical data take-out function to take-out the numerical data from the inside of the window 18 to the position of the cursor 17 in the document. When the data are fetched into the window 18 and the document data in the position of the cursor 17 are the numerical values, the train of figures in a range from the position of the cursor 17 into the window 18 in a line head position is copied into the window 18. When the data are taken-out from the inside of the window 18, the train of the figures displayed in the window 18 is copied from the position of the cursor 17 in the document in the line head direction.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a general-purpose or special-purpose document creation information processing device.

[Prior art 1] Conventional numerical calculation functions used in document processing either perform numerical calculation processing as a stand-alone auxiliary function, use the numerical calculation function independently of document data, or use numerical calculation functions within the document. It was only for inputting numerical calculation results to Moe's cursor position to activate the function. Therefore, if the numerical calculation function is started in the middle of document creation, only numerical calculation processing will be performed, so you can refer to any location in the document!
1. When performing numerical calculations while @, it was necessary to exit the numerical calculation function, move the cursor that indicates the character input position in the document, and start the numerical calculation function again.

[Problems to be Solved by the Invention] In the above-mentioned conventional technology, when numerical calculations are performed while referring to numerical data mixed in the document when creating a document, it is difficult to switch between document processing and numerical calculation processing, and to input data within the document. This has the problem that operations such as moving the position and inputting data become complicated. Therefore, in order to solve these problems, the present invention shares part of the functions between the document processing function and the numerical calculation processing function, and enables them to exchange data with each other. The purpose of the present invention is to provide a means to efficiently perform numerical calculation processing during document processing even when a document contains a large amount of numerical data. .

[Means for solving the problem] In an information processing device having at least a document creation function, at least both functions of a document creation function and a numerical calculation function are provided by moving a cursor that indicates a character input position in a document. An information processing device characterized by:

(Embodiment 1) FIG. 1 shows the relationship between each state at the time of document creation and available functions in an information processing apparatus using the present invention.

There are two possible states when creating a document: character input only state 1
and numerical calculation only state 2, which can be switched to each other by key operation. In state 1, you can use the normal character input function 3. In state 2, you can use numerical calculation function 5 and exchange numerical data within the document 6, and move the cursor (and calculation window) in 4. can be used in either state 1 or 2.

FIG. 2 shows the overall process flow when creating a document based on the 1:function configuration shown in FIG.

Regarding key input during document creation, first, in step 7, it is determined whether the current state is a character input only state or a numerical calculation only state, and branching is performed, and then in each process, the key manually entered is determined. In step 7, if the current state is a numerical calculation only state, if the input key is a numerical or calculation key, perform numerical manual or calculation processing 8;
In the case of a key for changing the state, process 9 is executed to shift the current state to a character input only state, and in the case of a key for importing and retrieving numerical data, processing 10 is executed for importing and retrieving numerical data by copying it. , for the cursor movement key, the process 11 for moving the cursor and calculation window is executed, and the process returns to the state of waiting for human input. In step 7, if the current state is a character-only state, if the input key is a character key (including numeric/arithmetic keys), execute process 12 for character input; if it is a key for changing the state, execute process 12. A process 13 for shifting the current state to a numerical input only state is executed, a process 14 for moving the cursor is executed for keys for cursor movement, and the process returns to the key manual input waiting state again.

FIG. 3 shows screen examples of the two states of the information processing device according to the present invention when creating documents: a state 15 dedicated to text manual labor and a state 16 dedicated to numerical calculation.Which state is 615 or I6? Even in , the document contains numerical data as well as character data, and the cursor 17 indicating the major device in the document
In the numerical calculation only state 16 where is displayed, a window 18 (hereinafter referred to as
A calculation window) has been opened. Therefore, what changes when the state changes between states 15 and 16 by operating the state change key is the presence or absence of the calculation window 8, and the cursor 17 remains displayed in either state 15 or 16.

In the character input only state 15, characters are input to the cursor position, and in the numerical calculation only state 16, numerical values are input and calculated within the calculation window 18.

Furthermore, when the cursor movement is instructed, the cursor 17 is moved up, down, left and right, and to the beginning of the sentence, the end of the sentence, the beginning of the line, and the end of the line even in the dora state of 15.16. At this time, in the numerical calculation only state 16, the cursor 17 moves with the calculation window 18 attached thereto. When moving,
The screen scrolls as the position within the document changes.

15. The function of exchanging 'll value data between the two states of 16 is the function of importing numerical data from the cursor position in the document into the calculation window and the function of importing numerical data from the cursor position in the document into the calculation window in the numerical calculation-only state of 16. This is realized by the function of retrieving numerical data to the cursor position within. When importing data into the calculation window, if the document data at the cursor position is a numerical value, the number string within the range that enters the calculation window from there in the direction of the beginning of the line is copied into the calculation window. When retrieving data from within the calculation window, the number string displayed within the calculation window is copied from the cursor position in the document toward the beginning of the line.

Figure 4 shows the function of moving the cursor and calculation window, which is treated as a common function in the character input-only state and the numerical calculation-only state. This shows a further additional process of searching for the numerical data within and moving to the least significant digit. In this process, first, in step 19, all screen data related to the calculation window is saved, and then At step 20, the calculation window is erased by redisplaying the current entire screen without the calculation window.Next, at step 21, it is checked whether the document data corresponding to the current cursor position is a number.If the number is If not, search for the next number before the end of the sentence in step 22, and if it is not found, redisplay the document in its current state in step 26, and then use the calculation window saved in step 19 in step 27. Return to the original state by restoring the screen data.If the next number is found by the end of the sentence as a result of searching in step 22, the lowest digit of that number string up to the end of the line is set as the new cursor position and the process in step 26.27 is performed. If the document data corresponding to the current cursor position is a number in the determination in step 21, check in step 23 whether it is already in the lowest digit of the number string up to the end of the line. If it is already the least significant digit, use 21 to perform the same processing as if the current cursor position is not a number, and if it is not yet the least significant digit, use 24 to move to the lowest digit of the numeric string where the current cursor is located up to the end of the line. 26. Set digit as new cursor position.
27 and returns to the original state.

With the functions configured as described above, in response to a specific key operation while creating a document, a calculation window that displays numerical calculations will be displayed at the same time as a cursor that indicates the character input position in the document. Simultaneously, the calculation window is moved to an arbitrary position within the document by the same operation as moving the cursor within one document. This allows you to refer to any position in the document while the numerical calculation function is activated, and also allows you to specify the position within the document, allowing you to move between numerical data within a document, and to move from any position within the document. It becomes possible to realize functions of importing numerical data from a document into a numerical calculation function and retrieving numerical data from a numerical calculation function to a document. Therefore, by using these functions in combination, it is possible to efficiently carry out processing such as input, numerical calculation, and updating of a large number of numerical data scattered within a document while performing numerical calculation processing. For example, with the cursor still pointing at a specific position such as a table in a document, you can search for the next numerical data, move to that location, import the numerical values one after another into a numerical calculation function, add them, and then perform the numerical calculation. It can be used for tasks such as writing results to another location, and even if it is only for numerical calculations, you can move the cursor to display any part of the document on the screen and perform calculations while referring to it. It becomes possible to import numerical data from within a document, perform calculations, and retrieve it to another location within the document.

[Effects of the Invention] As described above, according to the present invention, it is possible to freely move within a document while the numerical calculation function within the document is activated, and it is possible to refer to any location within the document and exchange data. This allows you to perform numerical calculations while creating documents, which eliminates the hassle of manually moving a cursor to indicate the position of white text in a document, inputting numerical values, calculating numerical values, and updating numerical values, which are necessary for numerical calculation processing when creating documents. procedures can be significantly reduced. Especially when a document contains a large amount of numeric data along with text data, and it is necessary to perform numeric calculations frequently during the process of text creation, it is necessary to move between numeric data and to connect the document and numeric calculation functions. This has the effect of making it possible to process efficiently by using the function of exchanging numerical data between them in combination with the arithmetic function.
