Next, when the <rEXEJ key 11d is operated as shown in FIG. 4(3) to execute this transfer, the CP Ll 12 performs the control operation shown in FIG. 5 in response to this key operation.

FIG. 5 shows the processing contents when transferring data from the main RAM 14 to the option RAM 15. At the beginning of the operation, first, in step S01, the flag °0" is set in the IF flag register 13f as an initial setting.
Input the numerical value "2" into the P register 13G. Next, the process advances to step $02, and according to the value "2" of this MP key register 3a, data rAJ, which is the initial letter of the first name register, is read from the address "2" of the main RAM 14, MR is carried out, and the data rAJ is read out from the address "2" of the main RAM 14. Enter. Next step SO3
Then, according to the value "2" of the OP register 13C, data "S", which is the initial letter of the first name data, is read from address "2" of the option RAM 15 and inputted to the OR register 13d. Next, in step 504, a flag 0" is input and set in the N flag register 13e. Then, in step S05, which one of the initial letter data stored in the MR register 13b and the initial letter data stored in the OR register 13d is set. It is determined whether or not is the first one in the alphabet.Here, the data in the MR register 13b is rA.
Since the data in the OR register 13d is "S", it is determined that the data in the MR register 13b comes before the data in the OR register 13d, and then step 806
Proceed to. In step 306, the IF flag register 13
It is determined whether the content of f is "1". Here, the determination result is NO, and the process then proceeds to step SO7.

In step S07, O in the option RAM 15 is
Downshifts "2" and below designated by the P register 13c up to the rENDJ code. Thereafter, in step 808, data rAJ is read out from address ``2'' of the main RAM 14 in accordance with the value ``2'' of the MP register 13, and is inputted to the MR register 13b, as in step 802. Next, in step 809, the numerical value of the MP key register 3a is updated by "+1" to "3", and then in step 81
0, the data rAJ of the MR register 13b is set to option RAM according to the value "2" of the OP register 13c.
The data is written to the address "2" which became a blank area due to the downshift in step 807 of step 15. Next, as shown in step 811, the data rAJ of the MR register 13b becomes rl.
'# Determine whether it is a code. The determination result is NO, and the process proceeds to step 812. In step S12,
This time, data rAJ of MR register 13b is rEND.
Determine whether it is a J code.

The determination result is also No, and the process proceeds to step 813. Then, in step 313, the value "2" of the OP register 13C is updated by "+1", and then again in step SO7

In this way, by repeating the process of step 313 to step 807, the name data rAOKIJ of the main RAM 14 is written to addresses "2" to "5" of the option RAM 15. Then, when this writing is finished, the rlTJ code main R located next to the name data rAOKIJ
AM 14 and after this is layered into option R, AM 15 in step 310, step 3
If it is determined in step 11 that the code is an rlTJ code, the process proceeds to step 314. In step 814, it is determined whether the content of the N flag register 13e is "O". This is to determine whether the rrTJ code read from the register section 13 is located after the name data or after the telephone number data. Since the determination result is YES, the process advances to step S15. After the N flag register 13e is newly set to "1" in step 815, the process proceeds to step 313, where the OP register 13C is updated to "+1", and then the process returns to step 307.

By further repeating the processing of steps 507 to 813, the telephone number data "123-4564" corresponding to the name data rAOKIJ in the main RAM 14 is successively written into the option RAM 15. Then, when this writing is finished, The next located rlTJ code is read from the main RAM 14, and after this is written to the option RAM 15 in step 810, in step S11
If it is determined that the code is an rITJ code, the process proceeds to step 314. In this step 814, if it is determined that the N flag register 13e is not "0" but "1" and the rlTJ code is the one after the telephone number data,
Above is a set of data, namely rlTJrAOKIJ
The transfer of rlTJ r123-456J is completed, and the process then proceeds to step 302 described above.

In this step S02, data rHJ, which is the initial letter of the next name data, is read from the main RAM 14 according to the value of the MP register 13a, and is input to the MR register 13b. In the following step 803, the OP register 13c
Data "S", which is the initial letter of rsLIGAMOJ, which is the second set of name data, is read out from the option RAM 15 according to the value of , and is input to the OR register 13d. Next, in step 804, the N flag register 13e is set to 0''.
After inputting and setting, in step 805, it is determined which of the initial letter data stored in the MR register 13b and the initial letter data stored in the OR register 13d comes first in the alphabet. In this case as well, it is determined that the data in the MR register 13b precedes the data in the OR register 13d, and the process then proceeds to step 306. ,
At step 806, the contents of the IF flag register 13f are changed to “
If it is determined that the value is "O" rather than "1", the process proceeds to step 307.

Then, proceed to step 807 in the same manner as above.

By repeating the process, the second set of data rlTJ r) IAMURAJ rITJr in the main RAM 14
0425-79-12344 is transferred as the second set of data in the option RAM 15. Initial option RA
Data rlTJ stored in the first set of M15
rsUGAMOJ r■TJr123-985J is the third set of data at this point.

Further, in step 802, data rYJ, which is the initial letter of the next name data, is read from the main RAM 14 according to the value of the MP register 13a, and this data is stored in the MR register 13.
Enter b. In the following step SO3, OP register 1
According to the value of 3C, data "S", which is the initial letter of rsLIGAMOJ, which is the third set of name data, is read out from the option RAM 15 and inputted to the OR register 13d. Next, in step 804, after inputting and setting 0'' to the N flag register 13e, in step S05, which of the initial letter data stored in the MR register 13b and the initial letter data stored in the OR register 13d is alphabetical. to determine which one is first.

In this case, the data rYJ in the MR register 13b is determined to be later than the data "S" in the OR register 13d, and the process then proceeds to step 316.

Input to R register 13d. Next, in step 304, N
After inputting and setting 7lag 0'' to the flag register 13e,
In step 305, it is determined which of the initial letter data stored in the MR register 13b and the initial letter data stored in the OR register 13d comes first in the alphabet. Here again, it is determined that the data rYJ in the MR register 13b is later than the data rTJ in the OR register 13d, and the process then proceeds to step 816.

Then, in step $16, the position of the rITJ code specified by the OP register 13c is sent two places further. In this case, the next code after data r789-3531J is not the rlTJ code but the rENDJ code, so this rE
When the NDJ code is sent, the process proceeds to step 802.

At step 802, data rYJ, which is the initial letter of the next name data, is read from the main RAM 14 according to the value of the MP register 13a, and is input to the MR register 13b. In the following step 803, the rENDJ code indicating the data end is read from the option RAM 15 according to the value of the OP register 13c, and the rENDJ code is sent to the OR register 1.
Enter into 3d. Next, in step 804, after inputting and setting 0'' to the N flag register 13e, in step 305, which of the initial letter data stored in the MR register 13b and the data stored in the OR register 13d comes first in alphabetical order. Determine if there is.Here, M
