This function copies 'doubles' into field 'field_name' of the given
attribute.


Specific Errors:
    PK_ERROR_bad_name               (MILD) The attribute does not have a field
                                           with this name
    PK_ERROR_field_of_wrong_type    (MILD) The field is not a double field
    PK_ERROR_bad_value              (MILD) The field data is in some way
                                           invalid for the intended field.
    PK_ERROR_not_same_length        (MILD) The 'attrib' is a no-roll attribute
                                           and 'n_doubles' is not equal to the
                                           existing field length


The new data replaces any existing data stored in the field.

If 'n_doubles' is zero then this field is set to be empty.
