    You have fallen over the 256 byte problem. It is documented in the DML
    Rference Guide for Obtain Using.

    USING
    Specifies the sort control element to be used in searching the sorted
    set.
    sort-key
    The symbolic name of a field defined in working storage that contains
    the value of the sort control element.
    Note: Due to the architecture of the client interface for Advantage
    CA-IDMS, 256 bytes will be moved regardless of the actual length of the
    working storage sort key. This additional storage should be accounted
    for in order to avoid potential program exceptions that can occur. While
    these exceptions are rare, they are more probable if the sort-key is
    defined in a FILE or LINKAGE SECTION definition. To avoid this problem,
    it is recommended that the sort-key be defined in the program's WORKING
    STORAGE SECTION, padded to a full 256 bytes; and moved in and out of the
    FILE or LINKAGE SECTION fields.
