COBOL Error Code :

040

Reason for this Error in COBOL

National Language initialization not set up correctly (Fatal) -You have tried to use the additional language variants, but the environment or side file that is required to set up the language either has not been set up correctly, or does not exist, or is invalid. This might be because you have the LANG environment variable set for use by another system in a format not recognized by this COBOL system. -Set up the required environment or side file before you try to run the program again. Use the COBLANG environment variable to set the locale information for the COBOL system. See the chapter NLS Support in your Programmer’s Guide to Writing Programs.
