What does it do? 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 and ended by ENDCLASS. 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. The variants of CLASS without ENDCLASS are used for the publication of classes in a program and the declaration of local friends of a global class.
The statements CLASS and associated statements ENDCLASS can be specified only in the global context of a program. CLASS and ENDCLASS cannot be specified within classes, procedures, and processing blocks implemented internally as a procedure (event blocks for GET and AT SELECTION-SCREEN). This applies in particular to the variants of CLASS specified here, which is not closed using ENDCLASS.
