Hi Viktor. Thanks again for taking a look at this and giving me advice. I hadn't thought of the problem like this, using kind representation. The short answer is that I'm not sure yet whether there are any other requirements that bear on this, given the exploratory nature of the little project, but having just played with your modifications and then worked it back to the main code, this solution looks excellent at this stage. Really appreciate it.
