Instruction Operands
NOP None
This is a no-operation instruction and has no effect on the previous
operation.
NOP is used in the following cases:
1. To provide space for debugging of sequence programs.
2. To delete an instruction without changing the number of steps.
(Overwrite with NOP)
3. To delete an instruction temporarily.

Pointers (P)
Pointers are used with the jump instructions (CJ, CALL) in two different
ways as follows.
1. Designation of the JUMP destination (CJ) and at the head of
destination (Label).
2. Designation of the subroutine destination (CALL) and at the head of
the subroutine program (Label).
A
label number cannot be used at more than one place. If used, more
than once an error will occur.
