  Should be
  
  StmpTab.DS1.DataSet := DM.ArcTab;
  StmpTab.DS1.DataSource := DM.DSTab;
  StmpTab.StTab.LoadFromFile(DM.cPth + 'Templates\TabeVet.fr3');
  StmpTab.StTab.DataSets.Clear;
  StmpTab.StTab.DataSets.Add(StmpTab.DS1);
  StmpTab.StTab.ShowReport;

  I thank you for suggestions, but it doesent works.
  
  I previously converted an old FR2.7 list report changing old [DM.ArcTab."CodTab"]
  with [DS1."CodTab"] (picked from the dabase list in DesignReport), but no value printed. It means an empty report is displayed.
  
  What's wrong?

  I can't say what's wrong. Probably you should redesign your old report (avoid setting TfrxReport.DataSets in code, do it in the report designer).
