The runtime system uses the following rules to decide what the configuration file is called: 
               	 
            
 
            	 
             
               		
               - If the 
                  		  -c runtime option is used, the configuration file is the one named by that option 
                  		
               
- If the operating system environment variable A_CONFIG is defined, its value is the name of the configuration file 
                  		
               
-  The configuration file is named according to the host operating system. This depends on the operating system used by the
                  machine, as outlined in the following table: 
                  		
               
                
                  		   
                  		   
                  		  
                   
                     			 
                      
                        				
                        | System | Configuration File | 
 
                     		  
                   
                  		  
                   
                     			 
                      
                        				
                        | Windows | %PROGRAMDATA%\Micro Focus\extend\10.5.0\cblconfi | 
 
                     			 
                      
                        				
                        | UNIX/Linux | /etc/cblconfig | 
 
                     		  
                   
                  		
               
              
            	 
            CAUTION:
            Don't give a data file a name that is the same as a configuration variable name. Doing so can cause problems if you map the
               data filename through a configuration entry. For example, if you have a data file named 
               		CURRENCY, the runtime system may confuse the data file with the configuration variable of the same name, inadvertently changing the
               default currency character. 
               	 
            
 
            	 
            Note: When a Windows configuration file is installed or created, the default destination directory is: 
               		
%PROGRAMDATA%\Micro Focus\extend\x.x.x
 
               		Where 
                  		  x.x.x is the installed version number of extend.
