    What do you wanna do? Parse a COM/EXE file (exe files don't start with a jmp, only coms do that)? Write assembly?

    If the first: the jmp instruction has a special format. You can look it up and then extract the jump offset from the hex codes. After that it's just a matter of a little math.

    If you write assembly, as you surely know, you just set a jump mark.
