      - In Solution Explorer, open the application configuration file for your project. By default, it has the file extension

- On the 
        Environment tab, enter a variable name and its value in the 
        Name and 
        Value fields, and click 
        Set. 
      
- On the 
        COBOL Switches tab, check the switches you require. 
      
- Click 
        OK. 
      
Note: If you run your application outside of the Visual Studio IDE, you need to set the environment variable 
        COBCONFIG.BLOCK to the location of the application configuration file in order for the switches and environment variables set for the application to be applied.
