You can create and maintain sequence definitions in a database using OpenEdge's Data Dictionary. OpenEdge stores all sequence values together in a single database block, and stores sequence names and their remaining attributes in a metaschema table named _Sequence.

For information on defining, editing, or deleting sequences in your database, see OpenEdge Development: Basic Development Tools (Character only) and, in graphical interfaces, the online Help for the OpenEdge Data Dictionary.

For information on using sequences in ABL, see Accessing and incrementing sequences.
