The KEY statement specifies the CA-Datacom/DB short name for a Default Key in the
CA-Datacom/DB table. The Default Key value governs the order in which records are
read. The Default Key is an optional
key that defaults to the
Native Key. The Native Key governs how records are stored and maintained.
You can specify another key as the Default Key if you want the records processed in
a certain order. You do not
want to specify a SORT clause to achieve that result. You can also specify a Default
Key with the DDBKEY=
data set option when you execute a SAS procedure.
If the CA-Datacom/DB
short name contains special characters or national characters, enclose
the name in quotation marks.
