In this paper we introduce the notion of a level grammar and a level language. We define an extension to the extended definable sets and we characterize ALGOL-like languages, extended definable sets, and extensions of those as languages generated by level grammars with different kinds of restrictions on the productions and the use of productions. Finally we investigate some relations between the families defined.
