Module: COM Interface 

interface IOptions : IDispatch;

To change option settings,

  1. Use the NewOptions method of the Server (IServer) object to create a new Options object.
  2. Change the values as needed, and
  3. Call Options.Save() to apply the changes

Option settings are not persisted anywhere so changes must be made each time a new program instance starts. 

Option settings apply to the current thread and any threads created after the current thread. Therefore, each thread can have its own settings.
