Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a calculation processing method in a personal computer or the like.

[0002]

2. Description of the Related Art Calculations using a calculator have a wide variety of calculations, and the rules are simple, so that anyone can easily calculate them.
And if the input is correct, the answer is reliable. But,
Calculators, as a rule, store and display only the ones immediately after, so they need to be carefully entered, and calculations are likely to be redone. On the other hand, in a method using a spreadsheet program or the like, checking and recalculation are easier than a calculator because the input process can be seen. However, in these methods, the contents of the calculations are fixed, and their knowledge is individually required. For example, the calculation of the sum often involves a subtotal, but the presence or absence and the position depend on the program. In addition, when creating a program, it is required to determine the definition of calculations and the like, and it takes time to study them. The method using the horizontal writing formula does not have these disadvantages, but it is a format that is not usually used, and it is difficult to check because the numerical values are far from each other. And these methods other than calculators generally assumed a large screen.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to easily perform various calculations including checks after the calculations. Specifically, it is an object of the present invention to provide a computer that can easily input various calculations and displays the entirety using a small display area.

[0004]

The above and other objects are achieved by a calculation processing method and a program therefor as set forth in the claims. In principle, the input is made as a set of a calculation command and a numerical value so that they constitute a calculation formula. This principle omits previous steps such as definition of calculation. Examples of the calculation instruction include four arithmetic operations instructions, a function such as "=", and a square root (hereinafter, a function calculation instruction is referred to as a "function instruction"), and others. It is desirable that the range of calculation instructions that can be actually input to the computer be wide. Note that these symbols in the display are not limited.

[0005] The input calculation command and numerical value are stored in a storage location corresponding to the input location. Input is basically performed by designating a storage location, but the designation operation is not essential. For example, if the input order matches the storage order, it is sufficient to simply add them.

For display, a display format is used in which display units each composed of a set of calculation instructions and numerical values are vertically arranged. In the display unit, their arrangement and size are elements that can be freely designed. By the way, ordinary formulas are written from left to right, but adding this principle makes it easier to understand.
FIGS. 1 and 2 are preferred display formats in this sense. As for the number of display units, two or more are necessary because they are arranged vertically. Although a number that can display the entire calculation formula is desirable, a display area can be reduced because a known technique such as scrolling can be applied. As a display method, the input calculation instruction or numerical value is displayed at a display position corresponding to the storage position. It is also possible to display the information before storing it in a predetermined place.

For the calculation of the input formula,
This is performed by a calculation instruction that outputs an answer such as "=" or a function instruction. In the calculation process, first, the calculation formulas stored from the beginning to the position before the calculation instruction are read in the storage order and calculated, and an intermediate answer of the calculation formula is derived. At this time,
The order of calculation may be internally changed according to the calculation instruction. If this calculation has already been performed, the result can be used. Next, a process corresponding to the calculation instruction is performed using the intermediate answer as an input. For example,
In the case of "=", the intermediate answer may be output as it is. If it is a function command, it performs a function calculation with the intermediate answer as input and outputs the answer. Finally, the output of the calculation command is regarded as a numerical value input next to the calculation command, and is processed by the above-mentioned storage method and display method.

The reason for performing the calculation in this manner is to further utilize the calculation result. For example, the calculation in FIG.
"+ 4 =" is input after the answer of "6". In the calculation in FIG. 12, the result is added after performing the calculation of 5%. If the calculation result is not used, for example, the answer is written down and initialized. Such a procedure makes entry and checking difficult. This is because the expression of the calculation is far from the desired calculation. Therefore, in the present invention, various calculations can be expressed by regarding the answer as an input numerical value.

As described above, various desired calculations are performed, and the results are displayed. In the above description, the order in which the steps of storing, displaying, and calculating work is not one.
This is because the order of storage and display may be any order, and the calculation presupposes only the step of storage.

The second and subsequent claims are obtained by optimizing the present invention in accordance with a calculation object or the like. Since all of them have the effect of reducing the number of key touches, it is desirable to have all functions as a computer. The aspect of the present invention described in claim 2 is used, for example, when inputting from a keyboard, and, similarly to a calculator, when a calculation instruction is input, the numbers input so far are input as numerical values. According to a third aspect of the present invention, for example, when a function instruction equivalent to “M +” used in a calculator is executed, the changed numerical value is displayed in a dedicated display area. According to a fourth aspect of the present invention, when a numerical value to be input next to the four arithmetic instructions is input by a function instruction, a function instruction combining the four arithmetic instructions and the function instruction is created and input. The function instruction in this case may be a simple transfer instruction. According to an aspect of the present invention, when a function instruction having a plurality of variables is input, a numerical value is input to the variable and the value of the variable is stored. That is, the types of functions that can be used are extended to those of a plurality of variables.

[0011] The embodiment of the present invention shown in claim 6 is claim 1.
The display format of the annotation is added to the display format of. Regarding the position of the display area of the annotation, it is desirable that the correspondence with the numerical value can be intuitively understood. For example, it is preferable to use left and right margins in FIGS. FIG. 13 shows an example in which the right side of FIG. 1 is used as a display area for annotations. Then, for example, when a calculation formula of horizontal writing is described in the annotation, an answer obtained by calculating the calculation formula is input as a numerical value. As described above, the annotation according to the present invention also has a character as a processing target. Note that the format of the calculation formula indicated by the annotation is not limited. This is because the format is based on the conversion means.

According to a seventh aspect of the present invention, a stored calculation formula is read, and a calculation command and a numerical value included in the calculation formula are input. Here, the format of the calculation formula to be read is not limited to that of the present invention. This is because the format is based on the conversion means.
According to an aspect of the present invention, for example, a plurality of numerical values stored in a memory or a file and a method of calculating the numerical values are designated to input a numerical value and a calculation instruction. A simple sum is a straightforward example.

BEST MODE FOR CARRYING OUT THE INVENTION

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. However, the following embodiments are merely illustrative in all aspects and do not limit the present invention. The display format is selected and described with reference to FIG.

Embodiment 1 Embodiment 1 is an example of a computer that recognizes the completion of input of a numerical value by inputting a calculation instruction key and performs a line feed. This computer can calculate with the same key operation as a calculator. FIG. 3 shows a hardware configuration for implementing the present invention. 1 is a keyboard for inputting calculation formulas and the like, 2 is a display device for displaying the calculation formulas, 3 is a processor for editing and calculating the calculation formulas, 4 is a storage device for storing the calculation formulas It is.

The keyboard 1 inputs numerical values, calculation commands, characters, and the like. The calculation instruction key is a key for inputting functions such as a square root in addition to the four arithmetic operations instructions. It is also assumed that a key for making various processing requests is provided. For key input, an alternative means such as a mouse may be used. For the display device 2, a small screen is sufficient. When a large screen is used, a plurality of screens may be displayed using, for example, a window type disk operating system. The storage device 4 has a storage area for calculation formulas and the like, the contents of which are shown in FIG. In FIG. 4, reference numeral 11 denotes a calculation formula storage unit, which stores a calculation instruction and a numerical value as one set in one line. The same applies to annotations. Reference numeral 12 denotes a control information area, which includes an intermediate answer (hereinafter, referred to as "IA") in calculation, a numerical value buffer for storing a numerical value being input, and the like. Here, at least the IA can use a register. It is desirable that the external storage device such as a floppy disk be provided in consideration of storage of calculations and the like.

FIG. 1 shows a display example in the case where "1 + 2 + 3 = + 4 =" is input using the keyboard in the computer configured as described above. When "1" is input, the first line is displayed. Next, when "+" is input, a line feed is started and "+" is displayed. Similarly, "2" is displayed on the same line. After repeating this operation, the computer performs a calculation triggered by the input of “=” and displays the answer “6”. Hereinafter, the state of FIG. 1 is similarly obtained. “>” Is displayed in the last line, which indicates a line under processing including a state of waiting for input (hereinafter, referred to as “current line”). If you enter four arithmetic instructions or function instructions in this line,
A calculation using the answer “10” can be added.
Enter a number to add a new calculation.

Next, control of this embodiment will be described with reference to the drawings. In the following description and flowchart, “display” means to display on the current line on the display unless otherwise specified. “Store” or “read” means to store or read in the current row of the calculation formula storage unit 11.

In FIG. 5, when the program is started, the flow of processing starts. First, necessary data such as a screen and a memory are initialized (step 20). In the initial setting, the first line is set to the current line, and all the calculation instructions in the calculation formula storage unit 11 are set to blank (hereinafter, this blank command is referred to as “SP command” and is treated as a calculation command indicating the start of the calculation formula). .). Thereafter, it is determined whether a key has been depressed from the keyboard 1 (step 22). If there is no input, the process returns to step 22 and waits for an input.

When the numeral or the decimal point key is depressed, after the judgment (step 24), accumulation is performed so as to add from the right to the numeral string in the numerical value buffer. Then, the accumulated numerical value is displayed on the current line of the display device 2 (step 2).
6). Thereafter, the flow returns to step 22 again, and a desired numerical value is input by repeating this loop.

When the key of the calculation command is depressed, the calculation command is determined (steps 28, 32, 4).
2) The following processing is performed according to the calculation instruction. (1) In the case of four arithmetic operations instructions The calculation instruction processing is called (step 30). In the calculation instruction processing, a line feed is performed after storing a numerical value, and storage and display of arithmetic operations instructions are performed. Next, the process returns to step 22 and waits for an input. (2) In the case of "=" The calculation instruction processing is called (step 34). In the calculation instruction processing, after storing a numerical value, a line feed is performed to store and display “=”. Next, a calculation process is called (step 36), the calculation result is stored in the current line, and the numerical value is displayed (step 3).
8). This numerical value is the result of calculating the input calculation formula. Then, the next line is set as the current line, and “>” indicating the current line
Is displayed to indicate a line feed (step 40). Thereafter, the process returns to step 22 and waits for an input.

(3) Function Instruction Processing of a function instruction is shown in FIG. In FIG. 6, there is a U-type instruction and an I-type instruction (steps 44 and 50).
These instructions are a type of function instruction, and will be described later in detail. Since ordinary function instructions such as a square root are different from these, the process goes to step 34 and performs the same processing as in the case of "=". However, the numerical value displayed in step 38 is the result of performing the function calculation. In addition, U-type instruction or I
In the case of a type instruction, only the input part is different, and the subsequent processing is the same as that of a normal function instruction.

The calculation instruction processing will be described. The calculation command processing (step 68) is called when a calculation command is input, and the flowchart is shown in FIG. First,
It is determined whether a numerical value has been input (step 7)
0). If there is a numerical value accumulated in the numerical value buffer, the numerical value is stored (step 72). Then, the next line is set as the current line, and ">" indicating the current line is displayed (step 7).
4). The calculation instruction is displayed and stored in the next line added (step 76), and returns to the calling source (step 78). If a numerical value has not been input in step 70, the display and storage of the calculation instruction are simply performed (step 76). Thereafter, the process returns to the calling source in the same manner (step 7).
8).

The calculation process will be described. The calculation process (step 80) is called by an input such as "=",
The flowchart is shown in FIG. First, necessary initial settings are made (step 82), and the top row of the calculation formula storage unit 11 is set as the current row in the calculation processing (step 8).
4). Thereafter, the calculation instruction and the numerical value are read from the current line (step 86). After determining the calculation instruction (step 8
8, 92, 96, 100), the following processing is performed according to the calculation instruction.

(1) In the case of SP instruction Since the calculation formula is started, a numerical value is set in IA (step 90). (2) In the case of a four arithmetic operation instruction IA and a numerical operation are performed in accordance with the calculation instruction, and the result of the operation is set in IA (step 94). For example, "+"
If the processing in the case of is expressed in an expression similar to a program, "IA
= IA + numerical value ”. (3) In the case of "=" Since IA is an answer, IA is stored (step 9).
8). (4) In the case of a function instruction Perform a function calculation using IA as the value of a variable, and output the result as IA
Is set and stored (step 102). For example, if the function is square root and IA is 4, then 2 is the value of IA,
Is stored.

When the processing of the current row is completed as described above, it is determined whether the current row is the last row of the stored formula (step 104). If it is not the last line, the next line is set as the current line (step 106), and the process returns to step 86.
By repeating this loop, calculation is performed for all input rows. If the current line is the last, the process returns to the calling source (step 108). If an error unique to the calculation such as overflow occurs in the calculation process, it is not necessary to terminate the program. Rather, it is better to return to the editing process after displaying the error, correct the error, and calculate again.

The basic part of the control is as described above. The calculation example of FIG. 1 can be realized only by the above-described parts. Next, a preferred modification will be described. The method of displaying numerical values in step 26 and the like is not limited to the calculator. Rather, it is often better to use a fixed-point format. It is also possible to handle numerical values including a symbol such as “＄”. It is desirable that the user can appropriately select these display methods according to the content of the calculation.

With respect to the SP instruction, only the input of a numerical value can be used as the start of calculation. In this case, even if there is a blank line in the middle, it does not affect the calculation, so that the degree of freedom such as correction is increased. In steps 40 and 74, the next line is set as the current line. If the current line is the lower limit of the display area, it is preferable to automatically scroll. A display area may be added. For example, it is also possible to add a column.

For the calculation, an ordinary algorithm or program may be used. For example, if the user selects “1+
This is effective if it is desired to input “2 × 2” to calculate the multiplication first. The calculation can be divided to shorten the response time of the calculation. That is, by storing the last row number and the value of IA after the calculation, and starting the calculation next time, it is not necessary to perform the same calculation every time in the calculation process. In addition, the calculation process may be called upon input of a calculation command or the like. However, with today's hardware, there is only negligible effect in normal calculations. This is because the processing speed of the CPU and the like is sufficiently fast.

The function instructions will be described below. In general,
Once the function and display of the calculation command can be defined, the calculation command can be increased simply by assigning the calculation command to a specific key. For example, the determinations of steps 42 and 100 and the processing of step 102 may be added.

The function instruction is not limited to a simple function such as a square root. For example, the function for calculating the average value of the input numerical values is an easy-to-use function because it is easy to further use the average value for calculation in the present invention.
Further, since the output is not limited to the answer, it is also possible to express the composition ratio of these numerical values as a percentage and display the numerical value as a numerical annotation. Functions implemented by commands, language instructions, and the like can also be functions of the present invention. For example, it can be assumed that handling of decimal numbers in the entire calculation formula and instructions in a third embodiment described later are performed using function instructions. This is because the former can be used as error information and the latter can be used as information for obtaining consistency between calculation formulas. As described above, since the calculation formula itself has the dual character of the procedure and the data, the range which can be considered as a function instruction or a calculation instruction is wide. It may be one that does not output an answer or one that does not need to calculate a calculation formula. Therefore, the expression and position of step 102 may be changed depending on the nature of the function. In some cases, it is better not to limit the input position by allowing the calculation order in the input to be changed internally. For example, it is an instruction to round off.

As for the input of a function command, it may be better to perform special processing according to the nature of the function. "M +", "M-" or "MC" used in calculators
Has the ability to change the value of a dedicated storage area. And
These function instructions may include a process of displaying the changed value in a dedicated display area. The dedicated display area is, for example, as shown in FIG.
1 is shown at the bottom. This saves the trouble of recalling and confirming the contents at the time of use, thus facilitating use.
Also, when a plurality of “M +” display lines indicate subtotals, there is also an effect that a dedicated display area indicates the total of subtotals. It should be noted that these function instructions are basically easy to use as an effect of the present invention. The method of adding these function instructions is as described above.
In the case of “M +”, in step 102, I
A is added to the dedicated storage area, and the value after the change may be displayed in the dedicated display area thereafter.

Although a numerical value can be input by a function instruction, when a numerical value to be input next to an arithmetic operation instruction is input by a function instruction, one function instruction combining the arithmetic operation instruction and the function instruction is used. It is preferable to create and input the function (hereinafter, the function instruction for combining is referred to as a “U-type instruction”). As an example of this, there are “MR” (or “RM”) used in calculators and function instructions related to percentage. The fifth line in FIG. 11 indicates that when “+” is input and then “MR” is input,
This indicates inputting as “+ MR”. The second line in FIG. 12 is a function that calculates and outputs a value of 5%,
This is the case of a function instruction displaying “5%”. The combined function instructions are easy to use because the meaning of the numbers is clear. When the other part of the calculation formula is corrected and recalculated, there is also an effect that the numerical value input by this function instruction is automatically corrected. Also, the method of combining is easier to input than the method of preparing all the function instructions related to combining in advance.

FIG. 6 shows a processing flow when a U-type instruction is input. In step 44, the key is determined, and if the instruction is a U-shaped instruction, the following processing is performed. First, the stored calculation instruction is read (step 45), and it is determined whether the instruction is an arithmetic operation instruction (step 47). If the instruction is an arithmetic instruction, a function instruction combining the arithmetic instruction and the function is created (step 48). Then, the process jumps to step 34 to perform the same processing as the normal function instruction after the calculation instruction processing. Step 4
If the four arithmetic operation instructions are not stored in step 7, the process jumps to step 34 without performing the combination, and the processing is performed as a normal function instruction. The combined function performs an operation in addition to the input of a numerical value. For example, if it is just “MR”, step 1
02, the value of the dedicated storage area is set in IA,
If it is "+ MR", it will be added to IA. The case of 5% of the function is the same as “MR” except that the value of 5% of IA is calculated. If "MR" is input normally, a dedicated storage area can be read, so that storage and display can be performed without calling for calculation processing. However, this is the case when the data is inserted in the middle of the calculation formula.

A function having a plurality of variables can be made the same as a function of one variable such as a square root by inputting the values of the variables. For example, in the case of a function F (x, y, z), x and y
To create a function instruction using IA as z. It is also possible to input z and use it only for inputting numerical values (hereinafter, a function instruction for inputting the value of a variable is referred to as “I
Type instruction ”). It should be noted that the I-type instruction may be a U-type instruction, and the U-type instruction may be an I-type instruction if the four arithmetic operations instructions are variables. In this way, it is possible to select a mold according to ease of use.

FIG. 6 shows a processing flow when an I-type instruction is input. In step 50, the key is determined, and if the instruction is an I-type instruction, the following processing is performed. First, the value of a variable is input (step 51). As a method, for example, a variable input screen is displayed. Next, a function instruction based on the value of the variable is created (step 52). The created function instruction is, for example, F (1,1, z). In the following, the process jumps to step 34, where normal processing is performed. The execution of the function instruction is the same as that of a function such as a square root, except that a process of reading the value of an input variable is added in step 102.

As a practical example, there is a function instruction “x%”. For example, if "5" is input as the value of x,
The function instruction “5%” shown above is created. If the function instruction stores the value of a variable as a character in a symbol, in step 102, the function is calculated after reading the character. Further, the determination method of step 100 is as follows:
"Does the calculation instruction include"% "in the symbol?" Other practical functions include functions related to interest rates and loans. Since “x%” is also a U-shaped instruction, it is better to jump to step 45 after step 52. Also, regarding the input of the value of the variable in step 51,
There is also a method that does not use the variable input screen. For example, "x
In the example of "%", "+5" is normally input, and a function instruction of "+ 5%" can be created by inputting "%". In this case, after reading "5" in the numerical buffer in step 51, it is necessary to clear the contents of the numerical buffer and its display.

Based on the above description of the U-type instruction and the I-type instruction, the function can be further extended. That is, the variable may be a calculation formula, or the function itself may be a calculation formula. For example, “sqrt2” can be an instruction to input the square root of 2. However, the extension should be in a range where the meaning can be understood intuitively, and is also related to the limitation of the size of the display area.

The correction of the input calculation command or numerical value in this embodiment will be described below. In the present invention, since all calculation formulas are stored, partial corrections can be made. It is useful not only for correcting errors but also for changing the numerical value so that the total value approaches the target value. The flow of the correction is as shown in FIG. If a correction request has been made, the key is determined in step 54 and a calculation command or numerical value is corrected (step 56). And when the correction is over,
The calculation process is called (step 58), and the calculation is performed again. When the recalculation is completed, the process jumps to step 22 and returns to the normal state. You may return after repeating the correction and recalculation.

The correction method in step 56 may be a common method including scrolling of the screen. For example, you can use it with word processing software. This is because the stored calculation formula can be regarded as a document. The end of the correction is performed, for example, by providing a dedicated key. When modifying on an item or line basis, the C key on the calculator can be used for this purpose. For example, a line to be corrected is specified by the up and down arrow keys, and the C key is pressed to correct the line.
The case where this line is not the last line is regarded as this correction request, and the timing of transferring the control to another line using the up and down arrow keys after the correction is defined as the end of the correction. This method is preferably simple in that the number of keys required for correction is small.

The annotation is described below. An example of the display is shown in FIG. Annotations are needed, for example,
Save it for later. Annotations can also be used as interface data for other processes such as printing. Preferably, a calculation instruction in which one line is a line including only an annotation is provided. Another use is to adjust the position of a particular row. FIG. 8 shows a processing flow of inputting the annotation. In FIG. 8, it is determined in step 60 whether the key is a comment input request key. If it is a comment input request key, enter characters,
Characters are displayed and stored (step 62). Then, the process returns to step 22 upon completion of the annotation input. As described above, the annotation is input to each line. Note that the storage area of the annotation may be secured upon input.

As the contents of the annotation, a horizontal formula or a data which can be converted into a formula can be described, and an answer obtained by calculating the formula can be input as a numerical value. A specific example is shown in FIG. In FIG. 13, the second line inputs the answer “4” by inputting “2 × 2”. The fourth line inputs “5.08” converted to centimeters by inputting “2 inch”. Similarly, if a unit price and a quantity are input, a format in which the unit price, the quantity, and the price are arranged in one line is obtained. Therefore, by adding necessary functions, it can be used for a slip input system or the like. As is clear from the above description, the corresponding part of the existing program can be used for the calculation of this part. When a complicated calculation formula including parentheses is calculated, it is easier and easier to use this calculation than to use the basic part.

FIG. 8 shows a processing flow. The processing is executed by pressing the calculation input request key. In FIG. 8, it is determined in step 64 whether or not the key is a calculation input request key.
If the key is a calculation input request key, a calculation formula input as a comment is calculated, the answer is input as a numerical value, and display and storage are performed (step 66). Then, upon completion of the input of the numerical value, the process returns to step S22. Step 62 may be called between step 64 and step 66, and a calculation formula may be input as an annotation.

A dashed line is shown below step 64 in FIG. 8, which indicates that other processing can be invoked. For example, saving and reading of a calculation formula, scrolling of a screen, input of a numerical value and a comment by copying, processing shown in the third embodiment, and the like can be considered. As described in the description of the function instruction, the calculation expression itself has a dual character of a procedure and data. Thus, the features that can be combined with the present invention are consistent with many commonly known software features.

Embodiment 2 Embodiment 2 is an example of a computer which inputs a numerical value and a calculation command as independent items. That is, the first embodiment
Is a modification of the control related to the movement between input items in. For example, it is preferable to assume a system in which the calculation formula storage unit 11 in FIG. 4 is used as an input screen as it is. In this case, a calculation instruction and a numerical value are input into each of the input boxes of the square frame.
Then, a calculation is instructed and the calculation result is displayed. As described above, the input control portion including the correction may be a common one, and therefore, the portion except the input control will be mainly described below.

The hardware configuration of the second embodiment is the same as that of the first embodiment.
And is shown in FIG. Next, the operation that characterizes the present embodiment will be described with reference to FIG. In FIG. 14, when the program is started, the flow of processing starts, and first, necessary data such as a memory is initialized (step 110). The input area of a plurality of rows is displayed on the display device 2 to input a calculation formula (step 112). The above is an ordinary program. Then, upon completion of the input or a calculation instruction, the calculation formula is stored in the calculation formula storage unit 11 from the input area (step 114), and the calculation process is called (step 116). Finally, upon completion of the calculation process, the calculation formula including the answer is displayed based on the calculation formula storage unit 11 (step 118). Thus, the calculations according to the invention are achieved. If the input area matches the calculation formula storage unit 11, step 114 can be omitted. Further, the functions such as the function instructions described in the first embodiment can also be applied to the present embodiment. This is because each function does not depend on control relating to movement between input items.

This embodiment can be applied to a slip input system. The required calculations can be expressed, and corrections and recalculations are possible. According to this method, even if there are many types of slips, the portion related to the calculation is dealt with by one program. Thus, computer resources are saved and system development is simple. Further, since the input method of each slip is unified, it is easy to use and practical. In a general system, calculation is not mainly controlled, but the first embodiment may be used as long as calculation can be controlled independently.

The present invention may be used under word processing software. For example, after describing a calculation formula in a text, the range of the calculation formula is designated by a cursor or the like, and the calculation is performed according to the present invention.
Then, the calculation result is edited with word processing software. In this case, the functions are shared with the word processing software, but are generally included in the present embodiment. If the calculation formula can be freely described in the same way as a sentence, it is necessary to copy the calculation formula into the calculation formula storage unit 11 in step 114 while adjusting the position. A numerical value and a calculation instruction may be detected and copied by searching for each character. Depending on the character search method, it is also possible to enter horizontal writing without line breaks. On the other hand, the processing result of step 118 is displayed in vertical writing according to the present invention regardless of the format at the time of input. This result is desirable even if the format at the time of input is changed. Although the expression of general vertical writing calculation is different from the display format of the present invention,
This is because they can be matched by a simple edit such as deleting the calculation instruction. In such editing, a function of deleting a calculation command only for display is useful. This is because if the calculation instruction is stored in the calculation expression storage unit 11, subsequent corrections and the like become easier. In this sense, it is preferable to treat the calculation command like format information displayed as needed.

Embodiment 3 Embodiment 3 is an example of a program for inputting a plurality of designated numerical values together with an indirectly designated calculation instruction. As a preferable application example, an example in which a large number of numerical values are divided and totalized will be described. The overall flow is as follows. (1) Divide the calculation target into appropriate units, and
The total is calculated using. The formulas obtained by the calculation are stored in files. (2) Designate these formulas in the file, read the values of each answer, and make them count. Then, the process returns to the first or second embodiment. This flow is in line with the practice of dividing and counting and checking. Furthermore, it is preferable that the procedure for stacking the tally is simply a repetition and is simple.

The part relating to the present embodiment is (2) and will be described in detail below. The hardware configuration is shown in FIG. 3 as in the other embodiments. However, the storage device 4
Stores the file touched in (1). It is assumed that the record of the file has the data name, answer, and calculation formula storage unit 11 as items (hereinafter, this data is referred to as “F data” to be distinguished from the data in FIG. 4). When the F data is input in a distributed manner, a system including a host and a terminal may be used. That is, the keyboard 1 and the display device 2 in FIG. 3 can be regarded as belonging to the terminal, and the processor 3 and the storage device 4 can be regarded as belonging to the host.

Next, the operation which characterizes this embodiment will be described.
This will be described with reference to FIG. The program in FIG. 15 operates under the program of the first embodiment, and is activated by a key that requests tallying. For example, step 6 in FIG.
After the determination of 4, it is assumed that the key is activated when the input of the key is detected. As the processing, first, initial settings such as a memory are performed. If necessary, a file is opened (step 120). Then, a plurality of F data are designated (step 122).

After the above preprocessing, retrieval of F data is started. First, using conditions such as detecting the end of a file,
It is determined whether the search for the F data has been completed (step 124). If there is unsearched F data, one F data is read (step 126), and it is determined whether the F data is the designated F data (step 128). If not, the process returns to step 124 to read the next F data. If it is the designated F data, the answer to the calculation formula is stored as a numerical value (step 130). Further, the next line is set as the current line (step 132), and “+” is stored in the calculation instruction (step 134). Then, the process returns to step 124, and all the F data is processed by repeating this loop.

When the search is completed, "+" is replaced by "=" in the calculation instruction of the current line (step 136). Since the calculation formula of the tally is stored, the calculation process is called and the tally value is stored (step 138). Thereafter, the calculation formula is displayed on the display device 2 (step 140), and the process returns to the calling source (step 142). Assuming that three pieces of F data are totaled and the respective answers are 1, 2, and 3, the same screen as that in FIG. 1 is displayed, and the process returns to the first embodiment.

In step 122, a plurality of F data are designated, but known techniques such as input of selection conditions can be applied.
In the present invention, since the display area of the calculation formula is basically small, if the display screen is large, a plurality of calculation formulas can be displayed simultaneously. In this case, it is desirable that they can be designated with a mouse or the like.

In step 130, the name of the F data may be input together with a numerical value as a comment. Useful for checking.
As for the numerical values to be totaled, numerical values specified by line numbers, annotations, and the like in addition to the answers of the calculation formulas can be used. Also, numerical data unrelated to the present invention may be used.

It is also possible to calculate a plurality of formulas for each row. As an operation, a calculation formula (for example, “A + B + C”) using names of a plurality of F data or equivalents of the names is input. As a process, a specified formula is read in a column of the array, a calculation specified in a row unit is performed, and a column of answers is created. After performing the above preprocessing, the row of the array is changed to F
The above processing may be performed assuming that the data is data.
