-Setmode will deal with the octals, so we dont need to.
-Setmode can also be caused to fail because of malloc().
 We test to see setmode() has failed. If it has we check errno.
 If errno == 0 then we have an invalid file mode. If not malloc
 has failed and we the print the error via err().
-Remove '?' case.
-Fix some data types. This is for the setmode fix above.
