must designate a database key item.
If you specify LOCATION MODE IS DIRECT, you must define item-name-1 as a
DATABASE-KEY item.
If you specify LOCATION MODE IS DIRECT-LONG, you must define
item-name-1 as a DATABASE-KEY-LONG item.
item-name-2
must specify an item of fixed length belonging to the record type.
You use LOCATION MODE IS DIRECT/DIRECT-LONG to enable you to assign the
database key of a record which is to be saved and to specify the sequence for sequential
processing.
You use LOCATION MODE IS CALC to specify a primary key to permit direct access to a
particular record or to a set of records with the same key values.
