It just occurred to me that all you are saying would make sense if
the standard prohibited variables with the PROTECTED attribute from
being passed as actual arguments to procedures unless the corresponding
dummy arguments have the attribute INTENT(IN).  If the standard does
impose such a restriction, I would very much like to where to find it.
