var
  
x, Position: integer;
  tmpstr, tmpstr2: string;
begin
  
tmpstr := Edit.Text;
  for x := 0 to Length(Edit.Text) do
  begin
    if 
Copy(Edit.Text, x, Length(strold)) = strold then
    begin
      
tmpstr   := Copy(Edit.Text, 0, x - 1) + strnew;
      Position := x;
    end;
  end;
  tmpstr2 := Edit.Text;
  if Position <> 0 then
    
Edit.Text := tmpstr + Copy(tmpstr2, Position + Length(strOLD), Length(tmpstr2))
  else
    
Edit.Text := tmpstr;
