Assumed-size would be a better choice in this case.  Seems inefficient 
to create a dope vector just to call a final routine.

But this seems just a special case of the more general problem of 
calling a subroutine with actual arguments that have a size that varies 
from one call to the next.  If that's what you anticipate happening, it 
is reasonable to declare the dummy argument as assumed-size.  If you 
declare the dummy as explicit-shape, expect a "not-so-good-programmer"  
hat and a chair in the corner facing the wall.

Cheers,
Bill
