(j3.2006) Interp F03/0091

The issue in the interp hinges on the term "named array" as used in 
04-007:[78:16].   Lots of things are "arrays", including components 
declared with a <component-array-spec> or a DIMENSION attribute 
04-007:[51:16], an array constructor, or an array section [107:26].  At 
least some of these are clearly not  "named" arrays.   By our usual 
meaning of "name" as a lexical token, something like struct%array would 
not qualify as a "name".  One might  reasonably conclude that 
struct%array was not a "named array" even if it is an array.

The main point of the discussion on Friday was that the question in the 
interp - whether len type parameters could be used in the 
<explicit-shape-spec-list> of an array component declaration, was 
already clearly answered by C442 [50:28-30].  (Well, ok, "clearly" might 
not be a good description of that constraint's wording, but Jim's point 
is still valid).  If you decide that an array component is not a "named 
array" then that's the end of the story, and there no issue.  If an 
array component is a "named array" then C542 and C442 are in conflict 
and that's the real issue that needs an interp.
