Description

The program DEMO_OO_TRANSACTION is a subroutine pool that does not contain any subroutines. Instead, the program contains the definition of the local class demo_class, associated with the transaction code DEMO_OO_METHOD. When the transaction is called, the program is loaded, one instance of the class is created, and the method is called.
