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 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.
