Opps, I saw after sending this that you changed the command
to Delete. I tried your new RHS on my notebook with my earlier
command which had Drop and did not notice you changed the command
also. Was running fast.

As I said, I know this can be done in other ways. I have
documented 5 different ways to do this already, not using Drop.

But my question was not how to do it in other ways, but
that Drop did not have the same syntax as Part. That is all.

Thanks,
