Hi,

one can refer to a class without defining the class before that point. But, the class has to be defined later on.

Program description: In this program , class C1 has an interface reference O2 declared with reference to class C2. But, before that, class C2 is not defined. It is defined later with a single public attribute , NUM .

This demonstrates the theme.

In the main section of the program, object : OBJ1 is created from class C1.

Then, an object is created from the reference variable O2 in class C1. Finally, the attribute num of that object is displayed.

Example:

Dump report ysubdel1.

CLASS C2 DEFINITION DEFERRED.

CLASS C1 DEFINITION.

PUBLIC SECTION.

DATA O2 TYPE REF TO C2.

ENDCLASS.

CLASS C2 DEFINITION.

public section.

data : num type i value 5.

ENDCLASS.

start-of-selection.

data : obj1 type ref to C1.

CREATE OBJECT obj1.

create object obj1->o2.

write:/5 obj1->o2->num .

Output 5

Thanks,

Class Load is used to load the class from Global library into the program .
