that can operate to maintain what appears as an automatic copy of properties on another page. Reference properties can eliminate the need for copying the contents of one value or page into one or more other values or pages.
To define a reference property, select the Reference Property box on the Behavior tab of the Property form.
Then use the Property-Ref method to link values from another page (known as the non-reference page) to a page of the reference property. Thereafter, changes to the non-reference page — through the Property-Set method, other methods, Declare Expression rules, and so on — also appear on the reference page.
