brief introduction

ZF assembly language PSW marks a bit in the register, and JZ decides whether to jump according to ZF. If ZF= 1 (indicating that the result of this operation is 0, otherwise ZF=0), jump; Otherwise, the state of not jumping to ZF is set according to the execution results of other instructions.

Jz=jump if zero, that is, jump when the zero mark is 1, which is often used to judge whether two numbers are equal with cmp.

Another way to write jz is je, je=jump if equal. Jz and je have exactly the same function.

JZ is the zero conditional branch instruction of accumulator A.

JZ rel； If A=0, then PC+2+rel->; PC； Otherwise, PC+2-> PC(rel: 8-bit address offset in the form of complement, with the value of-128 ~+ 127).
