Context-level localization values define the localization for an Open Client context.
When an application allocates a CS_CONTEXT structure, CS-Library assigns default localization values to the new context. On most platforms, environment variables determine the default values. For specific information about how default localization values are assigned on your platform, see the Open Client and Open Server Configuration Guide.
Because default localization values are always defined, an application needs to define new context-level localization values only if the default values are not acceptable.
