In this paper we provide examples of topological dynamical systems having either finite or countable scrambled sets. In particular we study conditions for the existence of Li-Yorke, asymptotic and distal pairs in constant-length substitution dynamical systems. Starting from a circle rotation, we also construct a dynamical system having Li-Yorke pairs, none of which is recurrent.
