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 condi-
tion for LEND(810) turns ON. Block program

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