WebCMP Compare Instruction 8086. The compare instruction (CMP) compares the data of the two operands and depending upon the result sets the flag.The destination operand remains unchanged. It compares the two operands by computing the difference of two operands and sets CF, ZF and SF flags. Format: CMP Destination, Source.
