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

 Message        Integer overflow occurred when computing the size of
                an array type.

 Description    An array type is larger than allowed on this
                platform.

 User Action    Reduce the size of the array type.  It may be
                possible to use a pointer type instead of a large
                array.  The storage can still be accessed using array
                syntax.
