Delphi-Quellcode:

function FilesEqual(const First, Second: TFilename; out DiffLine: integer): Boolean;
var
  s1, s2: TStringlist;
  i: integer;
begin
  Result := FileExists(First) and FileExists(Second);
  if Result then
    begin
      s1 := TStringlist.Create;
      try
        s1.LoadFromFile(First);
        s2 := TStringlist.Create;
        try
          s2.LoadFromFile(Second);
          i := 0;
          while (i < s1.Count) and (i < s2.Count) do
            begin
              Result := s1[i] = s2[i];
              if not Result then
                begin
                  DiffLine := i;
                  i := s1.Count;
                end;  
              inc(i);
            end;
        finally
          s2.Free;
        end;
      finally
        s1.Free;
      end;
    end;
