Fields=(column-name-list)

    Specifies the column or columns of the table to be loaded into
    the database. If you list multiple columns, separate the column
    names with a comma, and enclose the list of column names within
    parentheses. Also, this qualifier specifies the order of the
    columns to be loaded if that order differs from the order defined
    for the table. The number and data type of the columns specified
    must agree with the number and data type of the columns in the
    .unl file. The default is all columns defined for the table in
    the order defined.

    If you specify an options file in place of a list of columns, and
    the options file is empty, the RMU Load command loads all fields.
