Adaptive Server 15.0 supports longer identifiers on table names, column names, and index names: 255 bytes for regular identifiers, and 253 bytes for delimited identifiers. Because of the expanded limits, some system tables and functions now allow for longer identifiers.
Change identifier names with corresponding application changes for binding values. Make sure your existing applications are not binding names of identifiers with only 30 bytes (the previous limit), which may cause unexpected behavior, access violations, bus errors, or general protection fauls.
