Assembly Language - Division. The Reduced Instruction Set of all chips in the ARM family The carry flag is set to indicate that a successful subtraction is The zero flag is typically abbreviated Z or ZF or similar in most documentation and assembly languages. Along with a carry flag, a sign flag and an overflow flag, the zero flag is used to check the result of an arithmetic operation, including bitwise logical instructions. It is set if an arithmetic result is zero, and reset otherwise.
