The PROPERTY statement assigns an object data variable
operand as the implementation to a property, outside an interface
definition.
It is used if the interface definition in question is included from a copycode and is to be implemented in a class-specific way.
It may only be used within the DEFINE CLASS statement and after
the interface definitions.
The interface and property names specified must be defined in the
INTERFACE
clause of the DEFINE
CLASS statement.
| property-name | This is the name assigned to the property. |
|---|---|
| OF interface-name | This is the name assigned to the interface. |
| IS operand | The operand
in the IS clause assigns an object data variable as the place to
store the property value.
|
| END-PROPERTY | The Natural reserved word END-PROPERTY must be used
to end the PROPERTY statement.

The example contained in
the documentation of the METHOD statement shows how
the same interface is implemented differently in two classes and how the
PROPERTY statement and the METHOD statement are used
to achieve this.
