So your first > impression was more accurate than the result of thoughtful reflection :) Ah. You might be right - probably you are. I know there is some closely related stuff that goes back a ways and was just extended to the C character kind in f2003, but it might not have been that exact bit. I'm probably thinking of the rule for sequence association that allows the character length parameter to differ between the actual and dummy... as long as you are doing sequence association. But it might be a new rule that puts the scalar case under sequence association; that's probably it. Not worth dragging out the standards to check, but I bet that's it. -- Richard Maine | Good judgment comes from experience; email: last name at domain . net | experience comes from bad judgment. domain: summertriangle | -- Mark Twain -- http://mail.python.org/mailman/listinfo/python-list
