LEND (810) LEND(810) or LEND(810) NOT specifies the end of the loop. When
LEND(810) or LEND(810) NOT is reached, program execution will loop
back to the next previous LOOP(809) until the operand bit for
LEND(810) or LEND(810) NOT turns ON or OFF (respectively) or until
the execution condition for LEND(810) turns ON. Block program

Loop repeated
If the operand bit is OFF for LEND(810) (or ON for LEND(810) NOT),
execution of the loop is repeated starting with the next instruction after
LOOP(809). If the operand bit is ON for LEND(810) (or OFF for
LEND(810) NOT), the loop is ended and execution continues to the
next instruction after LEND(810) or LEND(810) NOT.

The status of the operand bit would be
reversed for LEND(810) NOT.
