I appreciate the help, Martijn, and I suspect I will find your suggestions
useful in the future, but they do not completely work for us in the present
instance. We are, in part, trying to determine if our script may have lost
its positional parameters because it was invoked by someone else using ".
ourscript --options" in a shell that does not support that, so it does not
help to know they could have done it better some other way.
