I wonder if there is a "real" difference between (a) a program that changes itself (even in a big way) (b) a normal program that has code like "if a then x else if b then y .." Theorem: for every program of type a there is program of type b that behaves exactly the same. (ie no differences in output, although there may be differences in the "black box") True? Martin
