<System operation>
(Calculator operation)
An outline of an example of the operation of the calculator 100 will be described with reference to FIG.

In step S101, the CPU 112 of the calculator 100 determines whether or not the currently set operation mode is the algorithm mode. When not in the algorithm mode, the process proceeds to step S102.

In step S102, the CPU 112 performs a process relating to the selected mode other than the algorithm mode. For example, as a general calculator, a process of performing an operation in response to an input using a number key and an operation key and displaying the result on a liquid crystal display 134 is performed. After that, the process returns to step S101.

When it is determined in step S101 that the algorithm mode is selected, the process proceeds to step S103. In step S103, the CPU 112 determines whether or not there has been an input to an input key 132 other than the execution key. When there is no input to the input key 132, the process proceeds to step S105. On the other hand, when there is an input to the input key 132, the process proceeds to step S104. In step S104, the CPU 112 performs processing according to the input to the input key 132. By this process, the user can create a program. After that, the process proceeds to step S105.

In step S105, the CPU 112 determines whether or not the execution key has been pressed. When the execute key is not pressed, the process proceeds to step S107. On the other hand, when the execute key is pressed, the process proceeds to step S106. In step S106, the CPU 112 performs an execution process. In the execution process, the program input by the user is executed. The calculator 100 operates according to a program, requests input, and displays a result. After that, the process proceeds to step S107.

In step S107, the CPU 112 determines whether or not the program is requested to be transmitted. When the transmission of the program is not requested, the process proceeds to step S109. On the other hand, when the transmission of the program is requested, the process proceeds to step S108. In step S108, the CPU 112 performs a program transmission process. In the program transmission process, the CPU 112 causes the two-dimensional code encoder 122 to create a two-dimensional code including information about the created program. The CPU 112 displays the created two-dimensional code on the liquid crystal display 134. This two-dimensional code may include other information such as information about the model of the calculator 100 in addition to the contents of the program. After that, the process proceeds to step S109.

In step S109, the CPU 112 determines whether or not the operation mode has been changed from the algorithm mode to another mode. If not changed, the process returns to step S103. That is, the above-mentioned processing is repeated, and the program is input, executed, and the two-dimensional code is displayed according to the user's instruction. When it is determined in step S109 that the mode has been changed, the process returns to step S101.

(Smartphone operation)
An outline of an example of the operation of the smartphone 200 will be described with reference to FIG. Here, the operation of the application software (application) related to the calculator 100 on the smartphone 200 will be described.

In step S201, the CPU 212 of the smartphone determines whether or not the currently selected operation mode is the program conversion mode. The program conversion mode is a mode for converting a program created by the calculator 100 into a program in another programming language according to the present embodiment, and presenting and executing the program before and after the conversion. When it is determined that the mode is not the program conversion mode, the process proceeds to step S202.

In step S202, the CPU 212 performs a process other than the program conversion mode. For example, high-precision calculation, graph drawing, data sharing among group members, and the like can be performed. After that, the process returns to step S201.

When it is determined in step S201 that the program conversion mode is set, the process proceeds to step S203. In step S203, the CPU 212 determines whether or not the program conversion instruction has been input. When the program conversion instruction is not input, the process proceeds to step S206. On the other hand, when the program conversion instruction is input, the process proceeds to step S204.

In step S204, the CPU 212 acquires the program created by the calculator 100. For example, the CPU 212 uses the camera 232 to take a picture of the two-dimensional code displayed on the liquid crystal display 134 of the calculator 100. The CPU 212 analyzes the acquired two-dimensional code and acquires the information represented by the two-dimensional code. This information includes a program created by the calculator 100. Further, this information may include other information such as information about the model of the calculator 100. The CPU 212 transmits the acquired information to the server 300. Upon receiving this information, the server 300 converts the program created by the calculator 100 into another program, and transmits the converted program to the smartphone 200.

In step S205, the CPU 212 acquires information regarding the conversion result of the program from the server 300. This information includes information such as the type of programming language, the converted program, and the line number of the program. The CPU 212 displays the acquired information on the liquid crystal display 224. After that, the process proceeds to step S206.

In step S206, the CPU 212 determines whether or not an arbitrary line in the displayed program list is selected while the two types of programs are displayed. The row selection is performed by, for example, touching any of the rows displayed on the liquid crystal display 224 by the user. The touch is detected using the touch panel 222. When it is determined that it is not selected, the process proceeds to step S209. When it is determined that the selection has been made, the process proceeds to step S207.

In step S207, the CPU 212 acquires information on a row selected by the user based on the detection result of the touch panel 222. The CPU 212 transmits the acquired row information to the server 300. The server 300 that has acquired the information on the selected row identifies the row corresponding to the selected row in the other program. The server 300 transmits information about the row selected by the user and the corresponding row identified to the smartphone 200. The information transmitted may include information about the image highlighting the selected line and the identified corresponding line.

In step S208, the CPU 212 acquires a specific result for the other row corresponding to the row selected from the server 300. Based on the acquired information, the CPU 212 causes the liquid crystal display 224 to display an image in which the selected line and the specified corresponding line are emphasized. After that, the process proceeds to step S209.

In step S209, the CPU 212 determines whether or not to change the arrangement of the two types of programs on the display screen. For example, when the smartphone 200 is fixed so that the screen is vertically long, two types of programs are arranged vertically. When the smartphone 200 is fixed so that the screen is horizontally long, two types of programs are arranged side by side. In such a case, when it is detected that the orientation of the smartphone is changed by using, for example, the output of the gravity sensor, it is determined that the arrangement is changed. When it is determined that the arrangement is not changed, the process proceeds to step S212. When it is determined that the arrangement is changed, the process proceeds to step S210.

In step S210, the CPU 212 acquires information regarding the arrangement such as the orientation of the smartphone 200. The CPU 212 transmits the acquired information regarding the arrangement to the server 300. The server 300 that has acquired this information creates information regarding the change in arrangement. The server 300 transmits the created information to the smartphone 200. This information may include data about the display screen.

In step S211 the CPU 212 acquires information about the screen whose arrangement has been changed, which is the creation result, from the server 300. Based on the acquired information, the CPU 212 causes the liquid crystal display 224 to display a screen showing two types of programs whose arrangement has been changed. After that, the process proceeds to step S212.

In step S212, the CPU 212 determines whether or not the operation mode has been changed from the program conversion mode. When the mode has not been changed, the process returns to step S203. As a result, when any of program conversion, line selection, and rearrangement change is selected, the selected process is executed, and when it is not selected, any process is not performed and the process waits. When it is determined that the mode has been changed, the process returns to step S201. Processing is performed according to the selected mode.

(Server operation)
An outline of an example of the operation of the server 300 will be described with reference to FIG. The server 300 performs various processes, and here, the operations corresponding to the operations described with reference to FIG. 4 will be described.

In step S301, the CPU 312 of the server 300 determines whether or not the information regarding the program conversion has been received from the smartphone 200. When the information regarding the program conversion has not been received, the process proceeds to step S303. When the information regarding the program conversion is received, the process proceeds to step S302. In step S302, the CPU 312 executes a conversion process of converting the received program created by the calculator 100 into a program using another programming language. The conversion process will be described in detail later. After that, the process proceeds to step S303.

In step S303, the CPU 312 determines whether or not information regarding row selection has been received from the smartphone 200. If no information regarding row selection has been received, the process proceeds to step S305. When the information regarding the row selection is received, the process proceeds to step S304. In step S304, the CPU 312 executes a selection process that identifies the lines of the other program corresponding to the selected lines and creates information for highlighting those lines. The selection process will be described in detail later. After that, the process proceeds to step S305.

In step S305, the CPU 312 determines whether or not the information regarding the arrangement change is received from the smartphone 200. When the information regarding the rearrangement change has not been received, the process returns to step S301. When the information regarding the rearrangement change is received, the process proceeds to step S306. In step S306, the CPU 312 executes an arrangement change process for creating information for changing the display of the two types of programs. The arrangement change process will be described in detail later. After that, the process returns to step S301.

(Conversion process)

Here, when the execute button is further pressed, a screen as shown by the reference numeral (n) in FIG. 8B is displayed, which becomes a program input screen.

In step S401, the CPU 312 acquires the first program created by, for example, the calculator 100 as described above from the smartphone 200.

In step S402, the CPU 312 converts the acquired first program into a second program written in a different programming language. At this time, as shown in FIG. 7A, the CPU 312 assigns line numbers to each instruction statement of the first program in order.

The second program corresponding to the first program as shown in FIG. 7A is as shown in FIG. 7B, for example.

"Go to x = -10, y = -20" in the first program is converted to "go to x: (-10) y: (-20)" in the second program.

The "Pen Down" of the first program is converted to "pen down" in the second program.

"Repeat 6" in the first program is converted to "repeat (6)" in the second program.

"Move 20 pixels" in the first program is converted to "move (20) pixels" in the second program.

The "Show Result y" of the first program is converted into "show (y)" and "wait any key" in the second program.

"Turn ↑ 60 degrees" in the first program is converted to "turn ↑ 60 degrees" in the second program.

The "Show Result x" of the first program is converted into "show (x)" and "wait any key" in the second program.

The "" "in the first program is converted to" "" in the second program.

The "(blank line)" of the first program is converted to "(blank line)" in the second program.

The conversion of the program as described above can be performed by referring to, for example, a correspondence table prepared in advance.

Subsequently, by the processing of steps S403 to S410, the line number corresponding to the line number of the first program is specified for each line of the second program.

In step S403, the CPU 312 sets the variable N indicating the number of processing lines of the first program to 1. Also, the sequence representing the row number of the second program is reset.

In step S404, the CPU 312 acquires the data on the Nth line of the first program. In step S405, the CPU 312 determines whether or not the syntax of the Nth line of the acquired first program is a syntax that increases the number of lines in the conversion of the program. Whether or not the syntax increases the number of rows and the number of rows to increase can be specified by referring to, for example, a correspondence table. When the number of lines does not increase, the process proceeds to step S406. In step S406, the CPU 312 adds one N to the sequence representing the row number of the second program. After that, the process proceeds to step S407.

In step S407, the CPU 312 determines whether or not the first program has the next line. When there is a next line, the process proceeds to step S408. In step S408, the CPU 312 adds 1 to the variable N. After that, the process returns to step S404. That is, the same process is repeated for the next line.

For example, as described above, in the conversion from the first program shown in FIG. 7A to the second program shown in FIG. 7B, the first to fourth lines of the first program are lines in which the number of lines does not increase. Therefore, when N = 1 to N = 4, the processing of step S406 adds one "1", "2", "3", and "4" to the sequence. As a result, the sequence becomes {1, 2, 3, 4}.

When it is determined in step S405 that the syntax is such that the number of lines increases, the process proceeds to step S409. In step S409, the CPU 312 obtains an increasing number of rows n based on the syntax, for example, by referring to the correspondence table. In step S410, the CPU 312 adds n + 1 N to the sequence. After that, the process proceeds to step S407.

For example, as described above, in the conversion from the first program shown in FIG. 7A to the second program shown in FIG. 7B, the number of lines in the fifth line of the first program is increased by one to two lines. Therefore, when N = 5, n = 1 is acquired by the process of step S409, and two "5" s are added to the sequence by the process of step S410. As a result, the sequence becomes {1,2,3,4,5,5}.

As described above, for example, for the conversion from the first program shown in FIG. 7A to the second program shown in FIG. 7B, the sequence {1,2,3,4,5,5,6,7,7 , 8, 9} is obtained.

When it is determined in step S407 that there is no next line, the process proceeds to step S411. In step S411, the CPU 312 assigns a row number to the second program based on the obtained sequence. For example, in the example of the second program shown in FIG. 7B, line numbers as shown in FIG. 7B are assigned.

In step S412, the CPU 312 creates data related to the screen to be displayed on the smartphone 200 by using the information of the first program and the second program and their line numbers. In step S413, the CPU 312 transmits the creation result of data related to the screen to the smartphone 200. The data related to the screen transmitted here may be image data of the display screen. In this case, the smartphone 200 displays the received image. Further, the data related to the screen to be transmitted may be text data. In this case, the smartphone 200 creates a display screen based on this text data. This completes the conversion process.

As a result, for example, an image as shown in FIG. 9 is displayed on the smartphone 200. That is, in the screen 600, the first program list 610 related to the first program and the second program list 620 related to the second program are displayed vertically side by side. The first program list 610 includes a line number 611 and an instruction statement 612. Similarly, the second program list 620 includes line number 621 and instruction statement 622. In the present embodiment, the line number 611 of the first program list 610 and the line number 621 of the second program list 620 are in a relationship that the same line number is assigned to the functionally corresponding instruction statement. Therefore, the user can compare the first program list 610 and the second program list 620 before and after the conversion, and can easily grasp the corresponding relationship.

Here, an example in which the correspondence between lines is indicated by a number is shown, but the present invention is not limited to this. Various codes such as alphabets and symbols can be used similarly.

(Selection process)
The selection process performed in step S304 will be described with reference to the flowchart shown in FIG.

In step S501, the CPU 312 receives the selected position from the smartphone 200. In step S502, the CPU 312 identifies the selected row based on the selected position. At this time, since the correspondence between the first program and the second program has been clarified, the selected lines of both the first program and the second program are specified. In step S503, the CPU 312 generates information for highlighting the identified lines for both the first and second programs. For example, create an image with the selected lines highlighted. In step S504, the CPU 312 transmits the result generated in step S503 to the smartphone 200. As a result, the smartphone 200 displays an image in which the selected line is highlighted.

For example, as shown in FIG. 11, it is assumed that the fifth line 613 of the first program list 610 is selected. At this time, the fifth line 613 of the first program list 610 and the corresponding second line 623 of the second program list 620 are highlighted.

According to the present embodiment, the corresponding line is highlighted, so that the user can easily grasp the correspondence relationship by selecting the line.

(Arrangement change processing)
The arrangement change process performed in step S306 will be described with reference to the flowchart shown in FIG.

In step S601, the CPU 312 determines whether to arrange the first program and the second program vertically or horizontally. The arrangement is changed according to the operation by the user. For example, when the smartphone 200 is arranged so that the liquid crystal display 224 of the smartphone 200 is vertically long, it is determined that the smartphone 200 is arranged vertically. For example, when the smartphone 200 is arranged so that the liquid crystal display 224 of the smartphone 200 is horizontally long, it is determined that the smartphone 200 is arranged side by side. When it is determined that they are arranged side by side, the process proceeds to step S602. When the first program and the second program are arranged side by side, it is easy to grasp the correspondence relationship if the corresponding lines in the instruction statement are arranged side by side. Therefore, in the present embodiment, in steps S602 to S607, a necessary blank line is inserted between the lines of the instruction statement of the first program according to the second program.

In step S602, the CPU 312 sets the variable N indicating the line number to be processed to 1. In step S603, the CPU 312 acquires the Nth line number of the second program.

In step S604, the CPU 312 determines whether or not the currently targeted line number is a repeating number. For example, in the second program shown in FIG. 7B, the line whose line number is "1" is not repeated. On the other hand, the line whose line number is "5" is repeated twice. When it is determined that the line number is not repeated, the process proceeds to step S606. On the other hand, when it is determined that the line number is repeated, the process proceeds to step S605. In step S605, the CPU 312 inserts a blank line below the corresponding line in the first program. After that, the process proceeds to step S606.

In step S606, the CPU 312 determines if there is a next line. When there is a next line, the process proceeds to step S607. In step S607, the CPU 312 adds 1 to the variable N. After that, the process returns to step S603. That is, for the line corresponding to the line in which the line number is repeated in the second program, a blank line is inserted in the corresponding line in the first program.

When it is determined in step S606 that there is no next line, the process proceeds to step S608. In step S608, the CPU 312 creates data for display with respect to the first program into which blank lines have been inserted, if necessary. This data may be image data for display.

In step S609, the CPU 312 uses the display data related to the first program created in step S608, and also uses the display data already existing for the second program to form the first program and the second program. Create display data arranged side by side (left and right).

In step S610, the CPU 312 transmits the created display data to the smartphone 200. After that, the arrangement change process ends. As a result, the smartphone 200 displays a screen in which the first program list 610 and the second program list 620 are arranged side by side.

FIG. 13 shows an example of the screen displayed on the smartphone 200. As shown in this figure, the first program list 610 and the second program list 620 are displayed side by side on the screen 600. Here, the statement of one line in the first program list 610 may be two lines in the second program list 620. With respect to such a line, by inserting a blank line in the first program list 610, the corresponding statements are displayed side by side in the first program list 610 and the second program list 620. As a result, the user can easily grasp the correspondence between the instruction statement of the first program list 610 and the instruction statement of the second program list 620.

The explanation will be continued by returning to FIG. When it is determined in step S601 that the arrangement is changed vertically, the process proceeds to step S611. In step S611, the CPU 312 uses the display data of the first program list 610 and the second program list 620 in which existing blank lines are not inserted, and the first program list 610 and the second program list 620 are vertically arranged. Create display data arranged in (upper and lower). After that, the process proceeds to step S610. At this time, the display data in which the created first program list 610 and the second program list 620 are vertically arranged is transmitted to the smartphone 200. As a result, a screen 600 in which the first program list 610 and the second program list 620 are vertically arranged is displayed as shown in FIG.

[Second Embodiment]
A second embodiment of the present invention will be described. Here, the differences from the first embodiment will be described, and the same parts will be designated by the same reference numerals and the description thereof will be omitted. In the first embodiment, it is assumed that the second program may have more lines than the first program, but it does not decrease. In addition, the number of lines to be increased is determined by the type of syntax, and it is assumed that the number of lines to be increased can be specified by checking one line of the statement. On the other hand, in the present embodiment, the number of lines in the second program increases or decreases with respect to the first program. In addition, the number of lines to be increased or decreased shall change depending on the description of the next line.

The conversion process according to the present embodiment will be described with reference to the flowcharts shown in FIGS. 14A and 14B.

In step S701, the CPU 312 acquires the first program created by the calculator 100 from the smartphone 200. In step S702, the CPU 312 converts the acquired first program into a second program written in a different programming language. At this time, the CPU 312 assigns line numbers to each instruction statement of the first program in order. In step S703, the CPU 312 sets the variable N indicating the number of processing lines of the first program to 1. Also, the sequence representing the row number of the second program is reset.

In step S704, the CPU 312 acquires the data on the Nth line of the first program. In step S705, the CPU 312 determines whether or not the syntax of the Nth line of the acquired first program is a syntax that increases the number of lines in the conversion of the program. When the number of lines increases, the process proceeds to step S706.

In step S706, the CPU 312 sets the variable k to 1. In step S707, the CPU 312 acquires the data on the N + kth line of the first program. In step S708, the CPU 312 determines whether or not it is necessary to confirm the next line in order to determine the number of increased lines based on the data of the N + kth lines of the first program. When it is necessary to confirm the next line, the process proceeds to step S709. In step S709, the CPU 312 adds 1 to the variable k. After that, the process returns to step S707. When it is determined in step S708 that it is not necessary to confirm the next line, the process proceeds to step S710.

In step S710, the CPU 312 determines a sequence indicating the number of corresponding rows in the second program based on the description of the instruction statements from the Nth row to the N + kth rows of the first program. For example, when the Nth row is converted to the 2nd row and the N + 1st row is converted to the 3rd row, the sequence becomes {N, N, N + 1, N + 1, N + 1}. In step S711, the CPU 312 adds the sequence determined in step S710 to the sequence indicating the number of rows in the second program.

In step S712, the CPU 312 adds k + 1 to the variable N. In step S713, the CPU 312 determines if there is a next line. When there is a next line, the process returns to step S704. That is, the process is repeated from the row not added to the sequence.

When it is determined in step S705 that the number of rows has not increased, the process proceeds to step S714. In step S714, the CPU 312 determines whether or not the syntax of the Nth line of the acquired first program is a syntax in which the number of lines is reduced in the conversion of the program. When the number of lines decreases, the process proceeds to step S715.

In step S715, the CPU 312 sets the variable k to 1. In step S716, the CPU 312 acquires the data on the N + kth line of the first program. In step S717, the CPU 312 determines whether or not it is necessary to confirm the next row in order to determine the number of reduced rows based on the data in the N + k rows of the first program. When it is necessary to confirm the next line, the process proceeds to step S718. In step S718, the CPU 312 adds 1 to the variable k. After that, the process returns to step S716. When it is determined in step S717 that it is not necessary to confirm the next line, the process proceeds to step S719.

In step S719, the CPU 312 determines a sequence indicating the number of corresponding rows in the second program based on the description of the instruction statements from the Nth row to the N + kth rows of the first program. In step S720, the CPU 312 adds the sequence determined in step S719 to the sequence indicating the number of rows in the second program. For example, when the Nth row, the N + 1st row, and the N + 2nd row are converted into one row, one value is added to the sequence. The value to be added may be, for example, the value of the first line such as {N}, or may be the value in which the line numbers are listed, for example, {N / N + 1 / N + 2}.

In step S721, the CPU 312 adds k + 1 to the variable N. After that, the process returns to step S713. That is, when there is the next row, the process is repeated from the row not added to the sequence.

When it is determined in step S714 that the number of rows does not decrease, the process proceeds to step S722. In step S722, the CPU 312 adds one N to the sequence. After that, the process returns to step S713. That is, when there is the next row, the process is repeated from the row not added to the sequence.

When it is determined in step S713 that there is no next line, the process proceeds to step S723. In step S723, the CPU 312 assigns a row number to the second program based on the obtained sequence. In step S724, the CPU 312 creates data related to the screen to be displayed on the smartphone 200 by using the information of the first program and the second program and their line numbers. In step S725, the CPU 312 transmits the creation result of data related to the screen to the smartphone 200. This completes the conversion process.

According to the present embodiment, when converting from the first program to the second program, it is possible to deal with cases where the number of lines increases and cases where the number of lines decreases. Further, according to the present embodiment, it is possible to deal with the case where the number of lines that increase or decrease changes depending on the content of the instruction statement. Therefore, it is possible to cope with conversion between various programs.
