Elements

Elements of values are values contained within other values. Composite values have elements; simple values do not. For example, the List value class definition, shown in List, contains one element, called an item.

You use references to refer to elements of composite values. For example, the following reference specifies the third item in a list.



 
item 3 of {"To", "be", "great", "is", "to", "be", "misunderstood"}

--result: "great"

The "Reference Forms" section of a composite value class definition lists the reference forms you can use to specify elements of composite values.
