You may place the DATE directive in front of a group item, as long as you also use the USE GROUP directive.
The source code for the animals table contains a group item for the date of the animal's last visit, and an elementary item for the date of the last payment:
05 last_visit. 10 yyyy pic 9(4). 10 mm pic 9(2). 10 dd pic 9(2). 05 fee pic s9(5)v99. 05 date_paid pic 9(8).
The date portions of a database table based on source code with this FD look similar to this illustration. All of these date-related fields are of type NUMBER in the (Access) database.
The examples that follow build on this source code.
