I ran the following program:

  int main(int argc, char *argv[])
  {
      for (int i = 128; i < 256; i++) {
	  if (isgraph(i))
	      printf ("G%d\n", i);
	  else
	      printf ("N%d\n", i);
      }
      return 0;
  }

on both the Zoo and a MacBook Air and all of the lines
becan with an N, indicating that all of these char
values (which include all of the option+char values)
are non-graphic.  Were you using the old version of
Hwk2/parsley?
