Description
When the execution condition turns on, the program jumps to the label (LBL) instruction that has the same
number as the specified jump number.
The program then continues with the instructions starting from the address of the label that is the jump
destination.
The same label is used for the JP, LOOP and F19(SJP) instructions. Any of these instructions can be used as
the starting point for the jump destination.
Two or more JP instructions with the same number can be used in a program.

Two or more LBL instructions with same number cannot be specified in the same program.
If a label for the jump destination is not programmed, a syntax error will occur.
