You mean an enum for UP, DOWN, EOF, etc.? Why isn't there one already used in Java instead the int array? Why is the current solution not sufficient?

I'd say you can still add this feature (if you manage to convince me of its necessity). C# may be late because I get my notebook back in one or two weeks (hopefully), but you can release 3.1.1 in the case that 3.1 is published before I can update the other stuff.
