User Defined Keys in GenFormat

You can create a user-defined SET for a data set by using the PRIMARY KEY construct in GenFormat. When a PRIMARY KEY exists, it is used instead of a SET that would otherwise qualify as the source for the index on the table. To properly identify the source of such an index, the DATABridge Client (v6.2 and later) sets the set_name to pk_set when it originates from a PRIMARY KEY construct. The DATABridge Client recognizes pk_set as a special name, the same as aa_set and user_set. The only difference between user_set and pk_set is their origin.
