Effect

The statement CLASS defines a class class, publishes it, or specifies properties.

The complete definition of a class consists of a declaration part and an implementation part, which are both introduced by CLASS. In the declaration part, the properties of the class are specified and its components are declared. In the implementation part, the methods of the class are implemented.

Further variants of CLASS are used for the publication of classes in a program and the declaration of local friends of a global class.
