This chapter discusses bilingual commands, bilingual forms, and double-byte character set (DBCS) data. Ask your QMF administrator whether you have the proper hardware and software necessary to operate with DBCS. National Language Support is available for DB2 QMF for Windows, but not for DB2 QMF HPO features, HPO/Manager and HPO/Compiler. See Appendix C. The DB2 QMF High Performance Option for more information.
