This paper may be considered as an attempt to obtain a synthesis of initial semantics and behavioural semantics. The initial algebra-like construction with behavioural semantics is discussed. A behaviour signature is considered as a signature of initial algebra with a set of observable sorts as an extra item. A considerable part of the article deals with the parameterized specifications. Their semantics is given by means of free constructions and their correctness is characterized. The semantics of parameter passing is presented.
