This applies to Windows environments (local development) only. COBSQL error messages can be displayed in different languages depending on the setting of the LANG environment variable.
Most database clients include some NLS capability but their requirements for the setting of the LANG environment variable differ from those of this COBOL system. We recommend, therefore, that you use the alternative environment variable, COBLANG, which only affects this COBOL system, allowing the LANG environment variable to be used by the database client.
Any other value triggers the default NLS locale.
