IsSequenced indicates whether sequence numbers are available for database records. 

Delphi syntax:  

         function IsSequenced: Boolean; override;

C++ syntax:

         virtual bool __fastcall IsSequenced(void);

Description  

Call IsSequenced to determine whether database records can be located by sequence numbers. When IsSequenced is true, the dataset can navigate directly to a specific record by setting the RecNo property. If IsSequenced is false, the only way to navigate to a specific record is to start at the beginning and count records.
