Other Examples
The instruction set of the PDP-11 computer includes an instruction for moving data, which when constructed in a particular form causes itself to be moved from higher addresses to lower addresses; the form includes an automatic decrement of the instruction pointer register. Hence, when this instruction includes autodecrement of the instruction pointer, it behaves as a dynamic self-relocator.
A more current example of a self-relocating program is an adaptation of the Apple Worm for the Intel 80x86 microprocessor, and its derivatives, such as the Pentium, and corresponding AMD microprocessors.
