The language identifier (QLANGID) is used to specify the default language identifier for the server.
This value also determines the sort sequence table to be used for sorting character data when the QSRTSEQ system value is set to *LANGIDSHR or *LANGIDUNQ.
You can change this system value to reflect the default language identifier for your country or location.
There is no validity checking between the QLANGID system value and the QCCSID system value.
