Component Reference by Index

The ref parameter denotes a variable or a data item (l-value) of a sequence or array type. The operator returns the sequence or array component determined by the index parameter. The index of the first element is 0.
The . (Component Reference) with an index parameter is equivalent to this operator.
For details, see the chapter on data references.
If the index is out of range, an error is returned.
