You can combine nearly any jump statement without its j-prefix to a single j and gain a new jmp statement. Take for instance the following example: WebShort jump—A near jump where the jump range is limited to –128 to +127 from the current EIP value. Far jump—A jump to an instruction located in a different segment than the current code segment but at the same privilege level, sometimes referred to as an intersegment jump. Task switch—A jump to an instruction located in a different task. higgs camera
