Procedure ChangeAttributes(FileName : String);
Var
  AttrFile  : File;

  GetFAttr(AttrFile, Attribute);
  if not ((Attribute = $10) or (Attribute = $12)) then
  begin
    WriteLn;
    WriteLn('Not a Directory');
    WriteLn;
    Exit;
  end;
  if Attribute = $10 then
  begin
    SetFAttr(AttrFile, Hidden);
    WriteLn;
    WriteLn('Directory ', FileName, ' hidden.');
    WriteLn;
  end
