VMS Help CC, Messages, BOUNDADJ  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 Message        The CDD description for <name> specifies
                non-zero-origin dimension bound(s); The bound(s) are
                adjusted to zero-origin.

 Description    The CDD description specifies lower bounds(s) for an
                array that is non-zero.  The resulting C definition
                will have the upper bound(s) adjusted for lower
                bound(s) of zero.

 User Action    Verify that all subscript expressions are referencing
                the correct array element(s).
