Accessing User-Defined Component Interface Properties
Every user-defined property in a Component Interface definition can be used like a property on the object instantiated from that Component Interface at runtime.
For example, the following Component Interface definition has RETURN_DT defined as one of its properties.
This example illustrates the fields and controls on the RETURN_DT Component Interface property highlighted. You can find definitions for the fields and controls later on this page.

At runtime, you can use PeopleCode to assign a value to that property (field), or to access the value of that field.
&MYCI.RETURN_DT = "05/05/2000";
/* OR */
&DATE = &MYCI.RETURN_DT;
