Résumé

We explore the borderline between decidability and undecidability of the following question: “Let $𝒞$ be a class of codes. Given a machine $𝔐$ of type $X$ , is it decidable whether the language $L (𝔐)$ lies in $𝒞$ or not?” for codes in general, $ω$ -codes, codes of finite and bounded deciphering delay, prefix, suffix and bi(pre)fix codes, and for finite automata equipped with different versions of push-down stores and counters.
