Description

[Detailed description of the invention] [Technical field of the invention] This invention relates to a small electronic calculator that enables matrix (array) operations.

[Prior Art and its Problems] Conventionally, in the case of small electronic calculators, such as pocket computers, when performing matrix operations, an array variable is defined as a method for inputting matrix element data, and matrix elements are stored in this array variable. A method of inputting data is used. For example, if DIM A(4,4) is defined as an array variable, to input data into such an array, A(1,1)=XX, A(1,2)=XX, A(1 ，
3)=XX, ..., A(4,4)=XX.

However, according to such a method, the position corresponding to the input data is not necessarily clear, so the operator always keeps in mind the position at which data should be input and confirms it while inputting data. For this reason, such input operations require considerable attention and familiarity, and are not only difficult to use but also prone to erroneous input.

Also, as a method different from this, there is a method using a BASIC program using parameters.
That is, an example of such a program is DIM A(4,4) FOR X=1TO4 FOR Y=1TO4 A(X, Y)=×× NEXT Y NEXT X.

However, this method not only takes a lot of time and trouble to create a program, but also
Programming errors are also likely to occur, and erroneous inputs caused by these errors are unavoidable.

On the other hand, as something more advanced than the input/output of matrix elements during matrix calculations, it is now possible to write/read various data used for grade processing, money processing, etc. to desired positions in a table partitioned into a matrix. Although so-called files have been considered, such cases also have the drawback that the positions corresponding to the data to be input and output are not clear, which can easily lead to erroneous input.

[Purpose of the invention] This invention was made in view of the above circumstances, and it is possible to clearly indicate the position corresponding to the input/output data on the layout display corresponding to the position of the input/output data,
It is an object of the present invention to provide a small electronic calculator that can reliably prevent erroneous data input/output operations based on the explicit position.

[Main points of the invention] The small electronic calculator according to the invention displays a layout corresponding to the position of input/output data in advance on a display means, and is provided with an input means for inputting position data of the input/output data. The position on the display means corresponding to the position data inputted from the input/output data is clearly indicated as the position corresponding to the input/output data.

The output of 0 is given to the display control section 11. The display control section 11 is supplied with matrix signals and data input/output signals from the control section 2 .

Here, when the display control section 11 is given a matrix signal from the control section 2, it sets the range of the display section 13 (described later), for example, the range from the right end of the display section 13 to the n-th dot, as a matrix layout display area. There is.

A display section 13 is connected to the display control section 11 via a display buffer 12 . Here, the display section 13 is one that displays a matrix of 192.times.32 dots, for example.

From this state, if you press key input section 1,
When MODE key 1f and DIM key 1e are operated,
The process enters matrix range setting mode and proceeds to step A2.

In this step A2, the display data of the control section 2 is transferred to the display control section 1 via the character generator 9.

Waiting for such a display, A(x,
y) is input, and the matrix range is set.
Specifically, use the numerical keys 1a, alphanumeric keys 1c, etc. of the key input section 1 to input A(4,4).
Enter as follows.

In this state, the process advances to step A4, where x and y input in step A3 are stored in the matrix setting data storage section 5, and x-y is inputted in step A5.
A matrix layout of is displayed on the display unit 13.

Here, to describe such a matrix layout display more specifically, in step B1 of the flowchart shown in FIG. to the n-th dot are set in the matrix layout display area. Then proceed to step B2.

In this step B2, the input of A(x, y) is waited, and if the number of dots in the x direction on the display section 13 is n and the number of dots in the y direction is M, then X=n/
x, Y=M/y is calculated, and the number of dots for one square is set in each of the x and y directions. The process then proceeds to step B3, where X and Y calculated in step B2 are written into the layout display data storage section 6. In this state, proceed to step B4 and step B5.

In these steps B4 and B5, data X and Y written in the layout display data storage section 6 are sent to the display control section 11 via the decoder 10. As a result, first, in step B4, the display section 13
x lines are displayed at every X dots from the right end of the screen, and then in step B5, (y-1) lines are displayed every Y dots from the top of the display section 13 with a length of n dots from the right end. The x-y matrix layout display is completed. x-y in this case
The matrix layout display of is shown in FIG. 5a.

In this state, returning to FIG. 2, it is determined in step A6 whether or not there is a key input on the MODE key 1f. Here, if there is no key input with MODE key 1f, return to step A2 and use a different key input than above.
If the DIM is set and a key is input, the process returns to step A1 and waits for the next input mode to be determined.

Next, when the MODE key 1f and the data in key 1h are operated on the key input unit 1, the input mode for a desired matrix element is entered, and the process proceeds to step A7.

In step A7, the display data of the control section 2 is given to the display control section 11 via the character generator 9, and "MAT?" is displayed on the display section 13.

Wait for this kind of display and press A at step A8.
(x, y) are input and the matrix range is set. The process then proceeds to step A9, where the x and y input in step A8 are written into the matrix setting data storage section 5, and the x-y matrix layout is displayed on the display section 13 in step A10.

In this state, proceed to step A11. This step
At A11, the display data of the control section 2 is given to the display control section 11 via the character generator 9, and "x?" is displayed on the display section 13. After waiting for this display, the value of x is input from the numerical key 1a of the input section 1 in step A12. Similarly,
Proceeding to step A13, the display data of the control section 2 is sent to the display control section 11 via the character generator 9.
"y?" is displayed on the display section 13. After waiting for this display, the value of y is input from the numerical key 1a of the input section 1 in step A14.

In this state, the process advances to step A15, where the x and y input in steps A12 and A14 are written to the matrix setting data storage section 5, and the position (x, y) on the matrix layout display is written in step A16. is displayed blinking.

Here, to describe the blinking display at the (x, y) position on the matrix layout display more specifically, when the x, y values are input in steps A12 and A14, as shown in FIG. In step C1 of the flowchart shown in , the blinking area on the matrix layout display is calculated. That is, x on the display section 13
If the number of dots in the direction is n and the number of dots in the y direction is M, then in the x direction of the display section 13, from the right end
X1 = n - =n-Y·y is calculated. Then, proceed to step C2, and X1 calculated in step C1,
X2, Y1, and Y2 are written into the layout display data storage section 6. In this state, proceed to step C3.

In this step C3, the data X1, X2, Y1, Y2 written in the layout display data storage section 6 is
is sent to the display control section 11 via the decoder 10. As a result, the areas surrounded by the X1 and X2 dots from the right end and the Y1 and Y2 dots from the bottom on the layout display of the display unit 13 are displayed blinking. In this case, if A (4, 4) is input for "MAT?" and "1" is input for "x?" and "y?", the blinking display in Fig. 5b is displayed. It comes to show. Here, the hatched area indicates the blinking area.

In this state, return to FIG. 2 and proceed to step A17. In step A17, the display data of the control section 2 is given to the display control section 11 via the character generator 9, and the display data of the control section 13 is displayed as "MAT A".
(x,y)? " is displayed.

After waiting for this display, matrix element data is input using the numerical keys 1a of the key input section 1 at step A18, and this data is written into the data storage section 4 at step A19. This means that the matrix element has been input into the blinking area on the layout display of the display unit 13.

In this state, in step A20, it is first determined whether or not there is a key input on the E key 1g. Here, if there is a key input, the process returns to step A7 and the input mode for matrix elements different from that described above is set.
On the other hand, if there is no key input, the process advances to step A21. In this step A21, it is determined whether or not there is a key input on the MODE key 1f. Here, if there is no key input, the process returns to step A11, and a data input area different from that described above is set; on the other hand, if there is a key input, the process returns to step A1, and waits for determination of the next input mode.

Next, when the MODE key 1f and the data out key 1i are operated on the key input unit 1, the mode becomes the matrix element output mode, and the process proceeds to step A22.

In step A22, the display data of the control section 2 is given to the display control section 11 via the character generator 9, and "MAT?" is displayed on the display section 13.

Wait for such a display and press A at step A23.
(x, y) are input and the matrix range is set. The process then proceeds to step A24, where the x and y input in step A23 are written into the matrix setting data storage section 5, and the x-y matrix layout is displayed on the display section 13 in step A25.

In this state, proceed to step A26. This step
At A26, the display data of the control section 2 is given to the display control section 11 via the character generator 9, and "x?" is displayed on the display section 13. After waiting for this display, the value of x is input from the numerical key 1a of the input section 1 in step A27. Similarly,
Proceeding to step A28, the display data of the control section 2 is sent to the display control section 11 via the character generator 9.
"y?" is displayed on the display section 13. After waiting for this display, the value of y is input from the numerical key 1a of the input section 1 in step A29.

In this state, the process advances to step A30, where the x and y input in steps A27 and A29 are written to the matrix setting data storage section 5, and the position (x, y) on the matrix layout display is written in step A31. is displayed blinking. Incidentally, since the blinking display at the (x, y) position on the matrix layout display is the same as that shown in FIG. 4 described above, the explanation here will be omitted.

Also, proceed to step A32, step A27,
The matrix elements of the data storage unit 4 corresponding to the x and y input at A29 are read out and displayed on the display unit 13.

Here, the blinking display at the (x, y) position on the matrix layout display is such that A (4, 4) is input for "MAT?", and for "x?", "y?" If "2" and "3" are input respectively,
The result is as shown in FIG. 5c. Here, the hatched area indicates the blinking area. Also, M.A.T.
The matrix element read out corresponding to A(2,3) indicates "5".

In this state, proceed to step A33. In this step A33, it is determined whether or not there is a key input with the E key 1g. Here, if there is a key input, the step
Returning to A22, the output mode for matrix elements different from the above is set, and if there is no key input, the step
Proceed to A34. In this step A34, it is determined whether or not there is a key input on the MODE key 1f. here,
If there is no key input, the process returns to step A26 and a data output area different from that described above is set; on the other hand, if there is a key input, the process returns to step A1 and waits for determination of the next input mode.

Therefore, according to such a configuration, by setting the matrix range in matrix calculation, it is possible to display a layout on the display section corresponding to the position of the matrix elements to be input and output, and moreover, Since the position area of the matrix element on the layout display can be clearly indicated with a blinking display and captured as a visual image, input/output of the matrix element can be performed with the positional relationship of the matrix element clearly understood. This makes it possible to reliably prevent erroneous input/output operations.

Note that this invention is not limited to the above-mentioned embodiments, and can be implemented with appropriate modifications within the scope of the invention. For example, in the above, the position of the matrix element is specified by inputting indexes such as "x?" and "y?", but the position of the matrix element can also be specified on the layout display by moving the cursor using the cursor keys. You can do it like this. This simplifies key operations and allows quick input/output of elements. In addition, if the x and y indicators of A(x, y) are automatically incremented as data is input, data can be input one after another while visually capturing the layout display on the display. can. Of course, the same applies to data output. Furthermore, although the above has consistently discussed the case of matrix calculations, it is possible to write/read various data used for grade processing, monetary processing, etc. to/from a desired position in a table partitioned into a matrix. It is also possible to apply this method to other applications.

[Effects of the invention] According to this invention, a layout corresponding to the input/output data position can be displayed in advance on the display means, and the position to which the input/output data corresponds can be clearly indicated on the layout display of the display means. This makes it possible to grasp the data input/output position as a visual image and perform input/output with a clear understanding of the data positional relationship, thereby reliably preventing erroneous input/output operations.
