So I have grouped these functionally, with all instruction synonyms in the same row. JNE JNZ, Jump if not equal. Jump if not zero, ZF = 0, 75, 0F 85. JB JNAE Top > 32. Logic Instruction List > 32.19 Compare Instructions (Time) > 32.19.6 JNE (<>) > 32.19.6.4 Explanation of the JNE Instruction 75 cb, JNE rel8, Jump short if not equal (ZF=0). 7E cb, JNG rel8, Jump short if not greater (ZF=1 or SF<>OF). 7C cb, JNGE rel8, Jump short if not greater or equal jmp loc. jmp loc. Loads EIP with the specified address (i.e. the next instruction executed will be the one specified by jmp). je loc. ZF = 1. jne loc. ZF = 0. jg loc. SF = OF and ZF = 0. jge loc. SF = OF or ZF = 1. ja loc. CF = 0 and ZF = 0. jae loc. CF = 0 or ZF = 1. jl loc. JNE label Short Jump if first operand is Not Equal to second operand (as set by CMP instruction). Signed/Unsigned. Algorithm: if ZF = 0 then JNE/JNZ - Jump Not Equal / Jump Not Zero; JNO - Jump Not Overflow; JNS mnemonics; Instruction syntax; op: Instruction OpCode; xx: Additional Code (Similarly, JNE and JNZ are just different names for a conditional jump when ZF is equal to 0.) (A CMP instruction performs a subtraction, and throws the value of the result away, while keeping the flags; which is why you get ZF=1 when the operands are equal and ZF=0 when they're not.) Instruction, Description, Condition, Opposite Instruction. JZ , JE, Jump if Zero (Equal). ZF = 1, JNZ, JNE. JC , JB, JNAE, Jump if Carry (Below, Not Above Equal). Description: Jumps to the destination label mentioned in the instruction if the ZF is 0, else no action is taken. Usage: JNZ dest, JNE dest. [dest: address in the
