Function
Operation without an Operand
EXIT(806) can be executed without an
operand. If it is, then an execution condition
must be created for it starting with LD. If the
execution condition is OFF, the rest of the
block program will be executed normally. If the
execution condition is ON, the rest of the
instructions in the block program through
BEND(801) will not be executed.

code
When the execution condition is ON (when an operand is not specified), or
when the specified bit is ON (when an operand is specified), the instructions
--- 806
from the EXIT instruction to the BEND instruction are not executed and the
block program is exited.
When the specified bit is OFF, the instructions from the EXIT NOT instruction
--- 806
to the BEND instruction are not executed and the block program is exited.
