DBCS Machine to Create an SBCS Application

By setting model value YIGCCNV to 1 in the source model, you define your model as DBCS. If you do this, you can generate an application that is both SBCS- and DBCS-enabled on the same machine. You can attach both DBCS and SBCS workstations to this machine, with English lower case installed as a secondary operating system.

With an English upper case DBCS operating system:

• System defaults are set to create all source, device files, and database files with ideographic character (IGC) enabling, assuming that you specified database fields with DBCS data types.
• The system value QIGC is set to 1, meaning the system expects to process IGC data. You cannot change this value.
• You can restore source and database files created with the IGCDTA parameter on an SBCS machine. However, you cannot restore source or database files containing ideographic data.
