FOOPS is a concurrent object-oriented language. We give a structured operational semantics for FOOPS, considering features such as classes of objects with associated methods and attributes, object identity, dynamic object creation and deletion, overloading, polymorphism, inheritance with overriding, dynamic binding, concurrency, nondeterminism, atomic execution, evaluation of expressions as background processes, and object protection.
