An extent field (also called an array field) is a field with multiple elements. Each element in an extent has the same data type.

The extent is the number of elements contained in an extent field. If you define a field with an extent greater than 0, that field is an extent field. Following both ways to create an extent field in the Data Dictionary.

On the Field Editor the Extent field is an integer; there is no check box. To create an extent field, enter a non-zero value into the Extent field.
