Next, the operation of the above embodiment will be described. First,
The overall schematic operation of FIG. 1 will be described with reference to the flowchart of FIG. When executing the processing operation, first, as shown in step A1, it is determined whether the processing mode is a simple language or a high-level language.

For example, when a table as shown in FIGS. 8A to 8C is created in a simple language and a processing mode of the simple language is designated, steps A1 to A2
After the fetch cycle shown in step A3, the process advances to step A3. In step A3, it is determined whether or not high-level language processing is required during tabulation processing in a simple language, that is, whether or not a high-level language processing request is issued, and a request is issued. If not, the process proceeds to step A4 to execute the instruction fetched in step A2.

In step A4, when the simplified language processing request issued from the high-level language control section 6 is accepted by the simplified language control section 5, an instruction for the request is executed. Then, in step A5, it is determined whether the execution of the instruction is based on the request from the high-level language control unit 6, that is, it is necessary to return to the high-level language processing.
If there is no need to return, go to step A6. In this step A6, it is judged whether or not the processing is completed. If it is not completed, the processing returns to step A2. Repeat the same process below,
A table as shown in FIG. 8 is created and stored in the RAM 7.

On the other hand, for example, when a high-level language is defined or arithmetic processing is performed and a processing mode in the high-level language is designated, the contents of the mode are discriminated in step A1 and the instruction fetch shown in step A7 is executed. After that, go to step A8. At this step A8, it is judged at this step A8 whether or not there is a processing request for using the simple language. If there is no simple language processing request, then the processing advances to step A9, and the instruction fetched at step A7 is executed.

In step A9, when the high-level language processing unit 6 receives a high-level language processing request issued from the simple language control unit 5, an instruction for the request is executed. Next, in step A10, it is determined whether the execution of the instruction is based on a request from the simple language control unit 5, that is, whether or not the process needs to return to the processing of the simple language.
If there is no need to return, go to step A11. In this step A11, it is judged whether or not the process is completed. If not completed, the process returns to step A7 and the same process is repeated. Also,
When the return instruction is detected in step A10, the process returns to step A6 of the simplified language processing flow. Further, when a return instruction is detected in step A5 of the simple language processing flow, the process returns to step A11 of the high level language processing flow.

Next, the case of creating the file shown in FIG. 8A will be described with reference to the flowchart of FIG. When creating a file, first, as shown in step B1 of FIG. 9, the simple language mode is specified by the mode switch in the key input device 2, and the file creation mode is specified in step B2. The simple language control unit 5 is designated by the above mode designation, and thereafter, file creation control is performed by the simple language.

Next, in step B3, the file name is input from the key input device 2. For example, when creating a stereo-related file, enter "FILE: STEREO" as the file name. After that, the number of records and the number of items are input as shown in step B4. In the case of FIG. 8, since the number of records (RC) and the number of items (IT) are both “4”, the number of records “RC: 4” and the number of items “IT:
Key in "4". Then, in step B5, a label record is input. This label record defines the contents of each item, and the definition contents are shown in Table 1 below.

[0026]

[Table 1]

Item 1 (IT1) in the above table indicates that the item content is "product name", the stored data is "character", and the maximum number of stored characters is "4". Item 2 (IT2)
Indicates that the item content is “unit price”, the stored data is “numerical value”, the maximum number of stored digits is “4”, and includes a 1-digit decimal value. For item 3 (IT3), the item content is "quantity",
The stored data is “numerical value” and the maximum number of stored digits is “4”. Item 4 (IT4) indicates that the item content is "total", the stored data is "numerical value", and the maximum number of stored digits is "4". Further, in the above item 4, in addition to the above, it is defined that the multiplication is performed by the operation contents, for example, the stored data of the items 2 and 3, that is, the multiplication of “IT2 * IT3” is performed and the multiplication result is stored as a total value. .. In this case, the above calculation is performed by designating a high-level language.

After the label record is input in step B5, the process proceeds to step B6 and item data is input. For example, in record 1 (RC1), IT1
"Amp" as the product name and "11.
Enter "5" 10,000 yen and "100" as the value of IT3. Also, other record 2 (RC2) to record 4 (R
Similarly for C4), each item data is input.
After the item data, the process proceeds to step B7, the calculation for the total item is executed in a high-level language, and the calculation result is registered in the RAM 7 at step B8.

Next, in the above-mentioned simple language processing, an operation in the case of requesting a high-level language processing and executing the processing will be described. When the file shown in FIG. 8A is created, a high-level language operation is required in the total processing of item 4. In this case, in step A3 of the processing flow shown in FIG. 7, the instruction decoder 53 shown in FIG.
Outputs a high-level language request signal from the high-level language request control unit 15 shown in FIG. As a result, the request flip-flop 61 in the high level language request control unit 15 is set as shown in step C1 of FIG.

Next, the simplified language control section 5 sets the program # in the program register 62 in FIG. 5A as shown in C2, and then sets the expression and variables in the variable register 63 as shown in step C3. .. Figure 8 (a)
When the file shown in is created, the total amount of money can be obtained only by specifying the calculation formula "IT2 * IT3" without specifying the high-level language program. Therefore, in step C3, the calculation formula " IT2 * IT
3 ”, that is,“ 11.5 × 10 ”for the record RC1.
0 ”is set.

Next, in step C4, the instruction decoder 53 sends a gate open signal to the high-level language request control section 15 to open the gates of the gate circuits 64a to 64c in FIG. 5A, and the flip-flop 61 and the registers 62 and 63. 6 is output to the high-level language request reception unit 36 shown in FIG. 6 (b). The high-level language request accepting section 36 unconditionally accepts the activation request signal from the flip-flop 61, and activates the high-level language managing section 32 as shown in step C5. As a result, the high-level language management section 32 starts the control operation, and first gives a gate open signal to the high-level language request reception section 36 shown in FIG. 6B via the instruction decoding section 34 to cause the gate circuits 93a and 93b to operate. Open the gate to open the register 62 of the high-level language request control unit 15,
The data from 63 is set in the registers 91 and 92.

Next, the high-level language management section 32 executes step C6.
As shown in, the initial address for the RAM 8 is set according to the set contents of the registers 91 and 92, and the process for the request from the simplified language control unit 5 is executed in step C7. In this case, the simplified language control unit 5 displays "IT
In the case of the expression "2 * IT3", that is, the record RC1, "1"
Since "1.5 * 100" is given, the calculation for the formula is performed. After the calculation is completed, the process proceeds to step C8, and it is determined whether or not a request signal is sent from the high-level language request control unit 15, and if there is no request signal, step A in FIG.
If the request signal has been sent as described above, the process proceeds to step C9 in FIG. In step C9, the flip-flop 71 of the simple language request control section 35 is set to generate a simple language request signal.

Then, the process proceeds to step C10 and step C7.
The calculation result obtained in step 3 is set in the data register 75.
The other registers 72 to 74 are used when the high-level language control unit 6 needs to process a simple language, and are not used in this case. After that, in step C11, the gates of the gate circuits 76a to 76e are opened, and the output of the flip-flop 71 and the data held in the registers 72 to 75 are sent to the simplified language request receiving unit 16 shown in FIG. 5B.
The simple language request receiving unit 16 uses a flip-flop 71.
Unconditionally accepts the request signal from and activates the simplified language management unit 12 as shown in step C12. As a result, the simple language management unit 12 starts the control operation, opens the gate circuits 85a to 85d of the simple language request receiving unit 16, and sets the data from the registers 72 to 74 of the simple language request control unit 35 in the registers 81 to 84. To do. At that time, as shown in step C13, the flip-flop 61 of the high-level language request control unit 15 is reset, and the process in the high-level language is returned to the process in the simple language. The high-level language management unit 32 also resets the flip-flop 71 of the simple language request control unit 35.

Then, the simplified language management unit 12 writes the calculation result obtained by the processing of the high-level language in item 4 of the file shown in FIG. 8 (a). The calculation process in the high-level language is performed every time data is input in each record, and the file shown in FIG. 8A is created by repeating the above process. In the file shown in FIG. 8 (a) above,
Although the calculation formula is defined for the label, if the calculation formula is different for each record, it may be defined for each record.

Next, the case of creating the file shown in FIG. 8B will be described. FIG. 8B shows an example of creating a triangle-related file. When writing a label record in record 0, the record number is specified in item 1 "R".
C ”, item 2 is the calculation formula“ SIN (RC * 45) ”, item 3
Program No. in high-level language Define "PROG # 0" and variable "A". This variable “A” is the above “RC”.
Is the value specified by.

The item data "RC" to be written in the item 1 (IT1) is "1" in the record RC1, "2" in RC2 and "3" in RC3. When writing data to record 1 and item 2, the expression "SIN
(RC * 45) ”is sent from the simple language control unit 5 to the high level language control unit 6 as described above. For example, record 1
Then, since “RC = 1”, the above equation becomes “SIN (RC
* 45) = SIN (1 * 45) ”, and the high-level language control section 6 calculates“ SIN 45 ° = 0.70711 ”. Then, the calculation result is returned to the simplified language control unit 5 and written in the positions of record 1 and item 2. And
When data is written at the positions of record 1 and item 3, the content "PROG # 0; A" defined in the label is the high-level language control unit 6
Sent to. When the simplified language control unit 5 designates a program, the high-level language control unit 6 reads the program and executes it. For example, if a program of 10 A = COS (RC * 45) 20 END is set in “PROG # 0”, “RC = 1”
In the case of

The calculation of "COS 45 ° = 0.70711" is performed. The calculation result is returned to the simplified language control unit 5 and written in the positions of record 1 and item 3. Similarly, RC2 and RC3 are calculated by the high-level language control unit 6, and the calculation result is written in a predetermined position.
The file of (b) is created.

FIG. 8C shows a case where the high-level language control unit 6 specifies the simplified language control unit 5 in PROG # 1 during program execution and writes the calculation result in the positions of record 1 and item 3 in file # 2. It is shown about the example of.
The above PROG # 1 uses the simple language control unit 5 in line 10.
On the other hand, the file # 1 shown in FIG. 8B is designated, the content “0.70711” of the record 1 and the item 2 is read, and the value is defined as “B”. Then, in line 20, define the formula “C = SIN (B) * COS (B)”,
The calculation result of “C = 0.01234” is obtained by the formula. Further, in the line 30, the simplified language control unit 5
A file # 2 is designated by sending a request signal to, and "C = 0.01234" is written in record 1 and item 3.
Similarly, the high-level language control section 6 writes predetermined data in the file # 2.

FIG. 8D shows an example of file creation when a sequence of instructions is written as item data. In this file, when a command is executed and a calculation formula is included in the step, the high-level language control unit 6 executes a calculation specifying a request signal.
