I think the table is being looked at wrongly. If you split the two stages
of IHAVE, it becomes more obvious:

                         IHAVE-1   IHAVE-2   CHECK     TAKETHIS
    send article:          335        -       238         -
    not wanted:            435        -       438         -
    xfer not possible:     436        -       431         -
    xferred OK:             -        235       -         239
    xfer failed, retry:     -        436       -        [???]
    xfer rejected:          -        437       -         439

The code in brackets could be 431 (dual-use, just like 436), or it can be a
separate code (on the "one situation one code" principle).
