Constants

IDL allows you to specify constant data values using one of several basic data types. To declare a constant, use the IDL keyword const.

    module Finance { 
      interface Bank { 
        const long MaxAccounts = 10000; 
        const float Factor = (10.0 ­ 6.5) * 3.91; 
        ... 
      }; 
    }; 

The value of an IDL constant cannot change. You can define a constant at any level of scope in your IDL specification.
