There will be a softball tournament on the 23rd at RL-5J location.

When inputting schedule data as described above, first, as shown in FIG. 5(1), the rI10J key 4e of the key input unit 4 is operated to specify the input mode. The key output data from the key input section 4 is stored in the counter 12.
The signal is sampled by the count value data from , is latched together with the count value data in the latch circuit 14 , and then input to the encoder 15 . The encoder 15 encodes the key code data of the r110J key 4e, which is the operation key, from the input key operation data (count value data and key output data), and stores it in the input buffer 16. rI10j key 4e stored in this input buffer 16
When the key code data of C is input to the CPU 11,
P U 11 thereby inverts the contents of I10 mode register 11a of RAM 111 and sets the input mode. Along with this, the display control unit 25 causes the display unit 3 to display the characters rN indicating that the mode is input mode.

Next, in order to input and set the file name, refer to Figure 5 (2).
), when the rM/AJ key 4f of the key input section 4 is operated, the contents of the M/A mode register 11b of the CPU RAM 111 are inverted, in the same way as in the case of the r110J key 4e described above. , alphabet specification mode is set. Along with this, the display control section 25 causes the display section 3 to display the characters rAJ indicating that the mode is the alphabet designation mode.

With this setting, the keyboard 6 becomes the alphabet specification mode, and the classification key becomes the alphabet entry key, so the actual file name rscH(JUNE)J
(meaning the schedule for June) by operating the classification key. When the classification key is operated, the processing shown in FIG. 6 is performed. That is, in the same figure, first, step A
At O1, the key operation signal operated on the keyboard 6 and the count value signal for key sampling output from the counter 13 are latched into the latch circuit 18 as matrix data.

Next, in step AO2, the M/A mode register 11b
Based on the contents of , it is determined whether the current keyboard 6 is in the matrix designation mode or the alphabet designation mode. In this case, since the keyboard 6 is in the alphabet designation mode, the process proceeds to step AO3, and the data of rscH(JUNE)J is encoded from the latch circuit 18 via the encoder 15 according to the operation key, and then sent to the input buffer 16. , the process corresponding to the classification key operation ends. Then, in order to instruct the completion of setting the file name, press the file key 4 of the key input section 4.

Next, as shown in FIG. 5(3), when the "rM/A" key 4f of the key input section 4 is operated again to input actual data, the M of the RAM 111 of the CPU ii is
The contents of the /A mode register 11b are inverted and the matrix designation mode is set, and at the same time, a switching signal is input to the memory area address designation unit 17, and the memory area address designation unit 17 becomes operational.

Subsequently, in order to designate a memory area, the user operates the classification key "(June) 1st" at the "7-'IJ" position on the keyboard 6, and the process shown in FIG. 6 is performed again. In this case, in step AO1, the key operation signal of the classification key at the "7-'IJ" position is input to the memory area address designator 17 and the latch circuit 18.

After the input signal is latched by the latch circuit 18, the process proceeds to step AO2, where the CPU 11 determines whether or not the keyboard 6 is currently in the matrix designation mode based on the contents of the M/A mode register 11b. In this case, the keyboard 6 is in matrix specification mode, so
As a result of the determination, the process then proceeds to step AO4. Step AO
In step 4, it is determined whether the operated classification key is the same as the previously operated classification key, and since the previous classification key operation has not been performed yet, the judgment result is ""No," and the process then proceeds to step AO5. In this step AO5, the memory area address designation unit 17
The operation of the classification key at the position r7-IJ on the keyboard 6 is determined from the signal from the counter 13 and the signal from the keyboard 6, and thereby the memory area at the position r7-IJ is specified in the classification memory 19. This classification memory 1

In this case, there is only a classification key operation for specifying the position of the memory area, and there is no input data, so the process proceeds to step A18, and the record memory 23 The record data rBUNA I specified in the record address register 241 of the record address specification section 24 from
-KA IGIJ to the C register 253 of the display control unit 25
Enter. Thereafter, in step A19, in order to display the number of items, the value "1" obtained by r+1J to the content "0" of the record address register 241 of the record address designation section 24 is set as the number of items data in the B register 25 of the display control section 25.
Set the input to 2. When the process of step A19 is completed, next step A13 is performed by the display control unit 25.
The matrix data r2-. input to the A register 251, the 8 register 252, and the C register 253 of 2 J, item number data “1” and record data rBUNAI-KAI
GIJ is displayed on the display section 3 together with the letter "M" indicating the matrix designation mode and the letter rOUTJ indicating the output mode, and the processing for the classification key operation at the r2-2J position is completed.

Next, as shown in FIG. 8 (4), when the classification key at the r4-2J position corresponding to "(June) 5th" on the keyboard 6 is operated, the first step in response to this key operation is as shown in FIG. A
After the matrix data r4-2J of the classification key operated by OI is latched in the latch circuit 18, steps AO2 and AO
The read/write control section 22 reads out the record data in the memory area specified in step AO5 via step AO5. Here, r4-2 of rscH(JUNE)J of the second file "1" of the classification memory 19
Since no record data has been input to the memory area at position 4, the read/write control unit 22 cannot read data, and no record data is written to the record memory 23.

Thereafter, in step AO6, the matrix data r4-2J latched by the latch circuit 18 is written to the A register 251 of the display control section 25, and in step AO7, the contents of the record address register 241 of the record address designation section 24 are cleared. After that, it is determined in step AO8 that the input mode is not in effect, and the process proceeds to step A17. If it is determined in this step A17 that no data has been input other than specifying the location of the memory area, the process proceeds to step A18, and the corresponding record is selected from the record memory 23 according to the content "0" of the record address register 241. The data is read and written to the C register 253 of the display control section 25. In this case, since there is no corresponding data in the record memory 23, the CP LJ 11 writes key code data of the character "?" to the C register 253 instead, indicating that there is no input data. After that, step A19
In step A13, the value "1" obtained by adding "1" to the content rOJ of the record address register 241 of the record address specifying section 24 is input and set as the item number data to the B register 252 of the display control section 25. The matrix data r4-2J, the number of items data "1" and the record data "?" input to the register 251, B register 252, and C register 253 are displayed on the display section 3, and the classification of the position 4-2J on the keyboard 6 is displayed. Ends processing for key operations.

As shown in Figure 8 (5) and Figure 8 (6), the keys on the keyboard 6 are "(June) 9th" and "(June) 11th" in the following direction.
rl-3 of rscH(JUNE)J of the second file "1" in the classification memory 19 by operating the classification keys at the N-3J position and r2-4J position corresponding to
Record data rGOLF-CONPEJ, rA-8HARA I from memory area at J position, r2-4J position
KYAKU (900~)” is matrix data N-3J,
r4-2J and the item number data "1" are displayed on the display unit 3.

Next, as shown in FIG. 8 (7), when the classification key at position r2-4J corresponding to "(June) 17th" on the keyboard 6 is operated again, steps AOI and AO2 are performed, and step A
At O3, it is determined that this operation classification key is the same as the previous operation classification key in FIG. 8 (6), and then step A1G
Proceed to. In this step A16, I1 of RAM 111
If it is determined that the current mode is not the input mode but the output mode based on the contents of the 0 mode register 11a, the process proceeds to step A20.

In this step A20, as in step A17 above, it is determined whether or not there is any data input other than the designation of the location of the memory area.Since no data has been input here, the process proceeds to step A21.

In step A21, the contents of the record address register 241 of the record address designation section 24 are updated by "+1" in response to the operation of the classification key at the same position.
Since the value was "0", "1" is newly set. After this, the record data rB-8HA RA I KYAKU (11
00~)'' is input to the C register 253 of the display side phloem 25. Next, in step A19, r+1JL is input to the content "1" in the record address register 241, and the value "2-" is input to the B register 252 of the display control section 25, and finally, in step A13, the value "2-" is input to the B register 251 of the display control section 25.
, B register 252, matrix data r4-2J input to C register 253, number of items data "2" and record data rB=sHA RAIKYA (1100~)
" is displayed on the display section 3, and the second r of this keyboard 6 is displayed.
The processing for the classification key operation in the April-February position ends.

After that, as shown in FIG. 8 (8) and FIG. 8 (9), when the classification key at the r2-44 position corresponding to "(June) 17th" on the keyboard 6 is operated again, the above-mentioned Figure 8 (
In the same way as in case 7), the contents of the record address register 241 of the record address designation section 24 are sequentially changed to "+1J".
The update setting is performed, and accordingly, the record data rSHINSE IHIN-HAPPYO (1300
~)'', rHANsE I-KA I (1600~)
'' are read out one after another and displayed on the display section 3 together with the matrix data r4-2J and the item number data r2J and r3J.

Next, as shown in Figure 8 (10), once rM/A
After operating the J key 4f to enter the alphabet specification mode and operating the classification key corresponding to the letter "S" on the keyboard 6, use the rM/AJ key 4t again to set the matrix specification mode and select the "(June)" on the keyboard 6. ) 17th”, if you operate the classification key at the r2-April position, “(
An initial search is performed for the record data of the initial letter "S" in the memory area of the r2-April position of the file address "1" of the classified memory 19 corresponding to "June) 17th". That is, in response to the operation of the classification key corresponding to the letter "S" on the keyboard 6 in the initial alphabet designation mode, alphabetical input processing for the letter "S" is performed in step AO3 via steps AO1 and AO2. remember. Then, "(June) 17th" on keyboard 6 in the next matrix specification mode.
For the operation of the classification key at the r2-April position corresponding to , this operation classification key is changed to the operation classification key in the previous matrix specification mode in FIG. 8 (9) in step AO4 via steps AOI and AO2. It is determined that the classification key is the same as r2-April position, and the process proceeds to step AlB. After it is determined in step A16 that the mode is not the input mode, it is determined in step A20 whether or not there is input data other than memory area designation in the matrix designation mode. Here, it is determined that there is input data due to the operation of the classification key corresponding to the character "SJ" on the keyboard 6 in the alphabet designation mode, and the process then proceeds to step A22.

In this step A22, in order to initialize the contents of the record address register 241 of the record address specifying section 24, the contents of the record address register 241 of the record address specifying section 24 are cleared in the same manner as in step AO7, and the clearing process of the record address register 241 is completed. Then, proceed to step A23. In step A23, the character data stored by operating the classification key in the alphabet designation mode and the record memory 2 according to the designation of the record address register 241 of the record address designation section 24 are stored.
The data of the first letter of the record data of the record address No. 3 is compared in the data comparison unit 113 of the CP IJ 11, and as a result of the comparison, it is determined in the next step A24 whether or not both data match. Ru. In this case, the input character data in the alphabet specification mode is "S", and the record data rA-81-(A RAIKYAKIJ(9
Since the initial data of "00~)" is rAJ, it is determined that the two data do not match as a result of the comparison, and the process then proceeds to step A25. In step A25, it is determined whether there is no record data at the address position specified by the record address register 241. Here, record data rA-8HA RAIKYAKU (900~)
" has been input, the judgment result is "No", and then in step A2G, the record address register 241
The content "○" is updated by "+1" to "1", and the process returns to step A23. In this way, this step A23~
Repeat the process of A26 and perform the second step A2B.
When the contents of the record address register 241 are set to "2" in step A23, the input character data "S" in the alphabet specification mode and the record data rsHINsEI specified by the record address register 241 are input in step A23.
HIN-HAPPYO (1300~) J f7) The initial letter data "S" is compared. Then, if it is determined that both data match as a result of the comparison in the subsequent step A24, the process proceeds to step A18, and the record data rsHINsEIHIN-HAPPYO (1300 to
)” is input to the C register 253 of the display control unit 25. After that, in step A19, the content "2" of the record address register 241 is set to r+1 J to display the number of items.
After the value "3" is input to the B register 252 of the display control section 25 as item number data, in step A13, the A register 251 and the B register 25 of the display control section 25 are input.
2, matrix data r2-4 input to the C register 253
J, item number data “3” and record data rSHl
N5E It-I IN-HAPPYQ (1300~
)'' is displayed on the display unit 3 together with the characters rMJ indicating the matrix designation mode and the characters rOUTJ' indicating the output mode, and the initial search process for the r2-4J position is completed.

Although not used here, the above step A17
If it is determined that there is input data, that is, instead of inputting the initial letter at the 2-4J position, which previously specified the memory area as shown in Figure 8 (10), another memory area is newly input. The initial search operations in steps A23 to A26 are also performed if it is determined that an initial letter has been input when specified.

Furthermore, if it is determined in step A25 that there is no record data corresponding to the initial letter when executing the initial search in steps A23 to A26, it means that the input of the initial letter or the specification of the memory area location is incorrect.
An error message is displayed on the display unit 3.
