Index data item

An index data item is a data item that can hold the value of an index. You define an index data item by specifying the USAGE IS INDEX clause in a data description entry. The name of an index data item is a data-name. An index data item can be used anywhere a data-name or identifier can be used, unless stated otherwise in the rules of a particular statement. You can use the SET statement to save the value of an index (referenced by index-name) in an index data item.
