Ouch! But thanks! I'll have a good chew over this evening. I know it's possible to have DT in C#, I think your literal of '3' in the above example is constructed using the successor function (well, its moral equivalent) at compile time, I just can't find the article I read and there's very little out there for DT in C# at all. And it's over my head until I sit down with a good example and work it through. I could use some simple DT for list lengths in my project.
