Sub UserProc;
Var
    MB: IMetabase;
    RubDesc: IMetabaseObjectDescriptor;
    RubrIn: IRubricatorInstance;
    DictInst: IMetaDictionaryInstance;
    MetaDLookup: IMetaDictionaryLookup;
    Conditions: IOrmConditions;
    Cond: IOrmCondition;
    Current: IMetaDictionaryData;
Begin
    MB := MetabaseClass.Active;
    RubDesc := MB.ItemById("OBJ_FC");
    RubrIn := RubDesc.Open(Null) As IRubricatorInstance;
    DictInst := RubrIn.Facts;
    MetaDLookup := DictInst.CreateLookup("");
    Conditions := MetaDLookup.Where;
    Cond := Conditions.Add;
    Cond.AttributeName := "COUNTRY";
    Cond.Value := 512;
    MetaDLookup.Open(DictionaryCursorOptions.None);
    While Not MetaDLookup.Eof Do
        Current := MetaDLookup.Current;
        Debug.WriteLine(Current.Record.Key.ToString);
        MetaDLookup.Next;
    End While;
    MetaDLookup.Close;
End Sub UserProc;
