Line 8:
Self-modifying code can involve overwriting existing instructions or generating new code at run time and transferring control to that code.
Self-modification can be used as an alternative to the method of "flag setting" and conditional program branching, used primarily to reduce the number of times a condition needs to be tested.
The method is frequently used for conditionally invoking [[test/debugging]] code without requiring additional [[computational overhead]] for every [[input/output]] cycle.
