Here's a question for all you FORTRAN language lawyers:


	Given a character (dummy argument) array declared

	       CHARACTER*(*) CARRAY(*)

	what is the ANSI-standard-conformant way of getting the length
	of each element?


From reading the standard, I had gotten the impression that
LEN(CARRAY)  was correct, and it works on my Sun workstation, but it
doesn't work on our CONVEX.  Instead, I had to write  LEN(CARRAY(1)).
Is the CONVEX compiler correct?  Or was my impression correct, and
the CONVEX compiler has a bug?  Or is this an area of ambiguity?  The
code I am writing has to be ultra-portable, so it is important what
is standard, rather than just what compilers A, B, and C accept.

Perhaps it would be best to just E-mail me, and I will post the
consensus ("one if by land,...")
