--- Comment #3 from Bil Kleb <Bil.Kleb at NASA dot gov> 2012-07-12 13:32:07 UTC --- OK, fair enough (and sincere thanks for taking the time to explain it). I see that if I change to the more modern ALLOCATABLE declarations, then I get a warning about assigning to an INTENT(IN). Thanks again, and sorry for the trouble.
