That of course goes near the top of the script.

I'll see if I can see a sensible place to add this one.

Thanks.  Its likely I'll be back because now that I think about it, that 
first line I quoted is quite likely from the function itself, and doesn't 
serve to establish the context of the call, hence the actual arguments to 
it.

Its one of those cases where, if the function were to also echo the 
arguments it was handed, the troubleshooting would be a lot more 
straightforward because you could then see the error causer right up front.

Cheers, Gene
