One can access the error string returned by the exception as follows:

  try
    AssignFile(...);
  except
    on E: EInOutError do
      ShowMessage(E.Message);
  end;

You can then use pos and copy to extract the error code from the string, since
the error string has a standard format. Another option is to turn off IO
checking and check IOResult after each IO call.
