| opcode_zero |
This isn't a legal opcode for users to use. However, the instruction execution code needs ot be able to dispatch this opcode in some cases.
|
| opcode_plus_equals |
"[+=] Plus Equal Key (also +key for addition)
"Depress to obtain results of addition, division, multiplication, sum of products and quotients. While the [AM1] key is locked, the result of division and multiplication is automatically added to Memory 1."
|
| opcode_minus_equals |
"[-=] Minus Equal Key (also -key tor subtraction)
"Depress to obtain results of subtraction, difference of products and quotients. Also depress it when entering negative numbers. When the [AM1] key is locked, the result of division and multiplication is automatically subtracted from Memory 1."
|
| opcode_mul |
"[x] Multiplication Key
"Depress in a multiplication after a muslItiplicand is entered."
|
| opcode_div |
"[/] Division Key
"Depress in a division after a dividend is entered."
|
| opcode_sqrt |
"[sqrt] Square Root Key
"Used for finding square roots. When this key is depressed the indicated value is square rooted. The result of the square root operation is indicated by a positive value regardless of positive or negative value. It is not necessary to depress the [+=] key after this key has been depressed."
|
| opcode_ent |
"[ENT] Entry Key
"This program key is used to store a temporary stop program instruction when programming in manual LRN. During execution of program at this instruction the program stops and the ENTRY lamp lights.
"It is used for the following: 1) Entry instruction to put the calculator in stand-by state for entry. 2) Temporary stop instruction for reading calculation results."
If the user presses SJ instead of START, execution will resume from the first program step (1 or 121, depending on the bank selctor switch).
|
| opcode_sj |
"[SJ] Sense Jump Key
"This program key is used for both manual program storage [LRN] and executing a program [OPE].
1) When storing a program: If this key is manually depressed, a sense jump instruction SJ is stored in the program, 2) When executing a program: If this key is manually depressed at the SJ instruction in the program, the program will jump to the specified program step. If the [START] key is depressed the program will proceed to the following step. The ENTRY lamp lights at this instruction."
|
| opcode_ej |
"[EJ] Entry Jump Key
"Like MJ and UJ instructions, this key is used for manual program storage.
"When this key is depressed with the Program Mode Switch in LRN position, an entry jump instruction EJ is stored in the program.
"During execution of a program at this instruction, the program stops to await entry of data and the ENTRY lamp lights. When an entry is made and the [START] key is depressed, a jump is accomplished to the specified program step; when the [START] key is depressed without entry, the program proceeds without jumping."
|
| opcode_mj |
"[MJ] Minus Jump Key
"Used for manual storing of programs. When this key is depressed, a minus jump instruction MJ is stored in the program.
"Minus jump instruction automatically judges the calculation results at the step immediately before this instructon is programmed; if the value is zero or positive it proceeds as it is, and if it is negative, it jumps to the specified program step."
|
| opcode_uj |
"[UJ] Unconditional Jump Key
"This key is used to store a manual program and to execute programmed calculation.
1) Storing program: With the program mode switch set to LRN, depressing this key during manual operation stores the unconditional jump (UJ) instruction in the program.
2) Executing programmed calculation: With the program mode switch set to OPE, pushing UJ n (entry keys [0] to [9]) causes a jump to the jump destination specified in the FJ n step instruction. This key isused for program subdivision and in programs involving a relatively large number of decisions. Refer to information on decision functions for details."
|
| opcode_fj |
"[FJ] Flag Jump Key
"This key is used in manual storing of programs in combination with [SJ], [EJ], [MJ], and [UJ] keys.
"If this key is depressed with Program Mode Switch set in LRN position, a flag for jump instruction is given, and a jump destination specifying instruction FJ is stored in the program. Each FJ instruction and the corresponding SJ, EJ, MJ or UJ instruction are accompanied by an identical flag code."
Note: actually, the flag value can be almost anything. Digits are merely very convenient, and not as confusing as other alternatives.

|
| opcode_rv |
"[RV] Reverse Key
"This key is used to interchange the multiplicand and multiplier in multiplications and the dividend and divisor in divisions. This key can also be used for checking and recalling a multiplicand, a divisor, an addend, or a subtrahend in multipIication, division, addition or subtraction."
"Note: It should be noted that the operation such as [0] [x] n [+=] [RV] recalls n instead of zero. Care should be taken not to program RV instruction, just after [+=] or [-=] instruction, to recall a of a x b where there is any possibility of becoming a zero."
|
| opcode_right |
"[->] Shift Key
"This key is provided to shift the indicated value one digit in the arrow indicated direction, and is mainly used when partially correcting accidentalIy entered digits. For example, if 2 3 4 is entered accidentally as 2 3 5, depress the [->] key once to change the indication to 2 3 then enter 4 to indicate 2 3 4. Similar action will also reduce a digit in the result of manual calculation."

"[C] Clear Key
"Used to clear all the calculating registers. Provided, however, that the memory is not cleared. When the program is in LEARN MODE (Program Mode Switch in LRN) the contents of a program are cleared in accordance with the instruction of the Program Selector Switch.
"When the program is in OPERATION MODE (Program Mode Switch is set in OPE), the program is returned to zero step.
"When the program is in CHECK MODE (Program Mode PRO CHE) the program is returned to either 1st or 121st step according to the Program Selector Switch.
"When the program is in OPERATION CHECK mode (program mode switch is at
OPE CHE) the program is returned to zero step."

| opcode_extended_start |
"[START] Start Key
"This key is used for execution of program calculation and to check the contents of a program.
1) Execution of program calculation: If this key is depressed with the Program Mode Switch set in OPE position, the program is advanced to the next ENT, SJ or EJ instruction in the program.
2) Program Checking: If this key is depressed with the Program mode switch set in PRO CHE position the contents of the program can be checked. The program is advanced one step each time the [START] key is depressed, and simultaneously the immediate step number and program instruction code are indicated together.
3) Checking program calculation With the program mode witch set to OPE CHE, depressing this key checks the program calculation. Each operation of this key advances the program one step, followed by arithmetic operation and display of the result.

"[M3~] Memory 3-9 Key
"Used to add the contents of the indicator to the contents of 3-9 memories. This key is used in combination with the 3-9 numeric keys. For example, to add 2 to Memory 5, operate keys [2], [M3~] and [5] in this sequence.
"Minus Memories 3-9 keys are not provided but, the [CHG SIGN] key is used to subtract the contents of the indicator from the contents of No. 3-9 memories. For example, to_subtract 2 from Memory 5, operate keys [2], [CHG SIGN], [M3~] and [5] in this sequence. Thus -2 is added to the contents of Memory 5; simply, 2 has been subtracted from Memory 5.
"Memories 10 through 14 are accessible only by program card. This also
applies to the [SM3~], [RM3~] and [CM3~] keys."
|
| opcode_extended_sm3_tilde |
"[SM3~] Storage Memory 3-9 key
"Similar to the [M3~] key, this key is used to read into No 3 through No 9 memories, but functions are different. That is, if the indicated value is stored in a specific memory by this key, the former contents stored in the subject memory are automatically cleared and only the new value indicated is to be stored.
"For example, let us assume that 6 is to be stored in Memory 5. If keys [2], [SM3~] and [5] are operated in sequence, the contents of Memory 5 is changed to 2 from 6."
|
| opcode_extended_rm3_tilde |
"[RM3~] Recall Memory 3-9 Key
"Used to recall the contents of No 3 to No 9 memories to the indicator. Like [M3~] and similar, this key is to be used with the 3-9 numeric keys.
"For example, to recall the contents of Memory 5, operate [RM3~] and
[5] in this sequence."
