                  -  The operating system's regional settings are used to determine which language environment to set up for this program. Use
                     the LANG environment variable to provide the desired settings. 
                     		
                  
  
                  		
                  - The NLS facility performs various operations in accordance with the rules of the language specified in the LANG environment
                     variable.
