WebBRANCH INSTRUCTIONS, CONDITIONAL JMP , JC , JNC, JZ , JNZ EXPLAINED WITH PROGRAM WebEach jump operation has three different forms, depending on the size of the operand. A short jump uses an 8-bit signed operand, which is a relative offset from the current instruction. A near jump is similar to a short jump but uses a 16-bit signed operand (in real or protected mode) or a 32-bit signed operand (in 32-bit protected mode only).
