Unlike Compatibility, Expected, and Maximum modes, which are literal strings that represent predefined export width definitions, DEFAULT is an SQL keyword that does not have a predefined meaning and is not delimited by SINGLE QUOTATION MARK characters.
If you specify DEFAULT as the Export Width for a user, the system assigns the export definition that is currently defined in the Export Width Table ID parameter of DBS Control to that user (see Database Utilities, B035-1102 for further information).
