Specifies a key field that governs the order that records are
read.

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, but 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.
