• The REF operator creates a data reference variable pointing to a specified data object.
• Sometimes it is necessary to pass a parameter to a method in the form of a data reference. This normally involves declaring a reference variable with type REF TO DATA, then using the GET REFERENCE OF dobj INTO dref statement. The new REF operator condenses this coding into a single expression.
• The REF operator replaces GET REFERENCE OF and is particularly useful for avoiding the declaration of helper variables that are only necessary to specify data reference variables as actual parameters.
