You can configure the COBOL run-time system environment to ensure it behaves appropriately for an application, regardless
               of the configuration used by other COBOL applications. 
               	 
            
 
            	 
            Run-time behavior can be controlled using environment variables, 
               		a run-time launch configuration file (Windows only), 
                  		run-time tunables, and run-time switches. 
               	 
            
 
            	 
             
               		
               You can specify some run-time features 
                  		  from within the IDE, as well as 
                     		  in a separate configuration file: 
                  		
               
 
               		
                
                  		  
                  - From the IDE - Setting certain run-time features in the IDE generates a binary format file. Eclipse creates a .gcf file that contains the run-time settings when you run the application. 
                     		  
                  
- A separate configuration file - In a text editor, create or edit a separate text file. See the individual sections for the
                     formats of the text files. Use the COBCONFIG environment variable to specify the location and name of the run-time configuration
                     file for environment variables, tunables, and switches.
