==Assembly style self-modifying code:==

The kinds of self-modifying code that are used in assembly can be for various purpusespurposes:

# Optimisation of a state dependant loop.

# Runtime code generation, or specialisation of an algorithm in runtime or loadtime (which is popular, for example in the ___domain of real-time graphics).

# Altering of inlined state of an [[object (programming)|object]], or simulating the high level construction of [[Closure (programming)|closures]].

# Patching of subrouting address calling, as done usually at load time of [[DLL|dynamic libraries]]. WhertherWhether this is regarded 'self-modifying code' or not is a case of terminology.

The second and third types are proboably the kinds mostly used also in high-level languages, such as [[LISP]].
