Comments on "Maximum-rank arrays codes and their application to crisscross error correction" [with reply]

It is pointed out that the results in the first four parts of the above-titled paper by R.M. Roth (see ibid., vol.37, no.2, p.328-36, Mar. 1991), which are devoted to the theory of the maximum-rank array codes over finite fields, are not new, but were published previously by the commenter. The author replies that he was not aware of the prior work until very recently. He points out some new results that were contained in the parts in question.<>
