Data-element localization values can be used to customize the following:
Bind variables (ct_bind)
If custom localization values are not specified, bind variables use localization values from the connection with which they are associated.
Conversion destination variables (cs_convert)
If custom localization values are not specified, conversion destination variables use localization values from cs_convert’s context parameter.
cs_time and cs_strcmp behavior
If custom localization values are not specified, these routines use the localization values associated with their context parameter.
You need to set up custom localization values at the data element level if the default values are not acceptable.
