There was a BACK command available as an add-on ProDOS BASIC command. I
think it was published in Nibble (hmm, as usual I can't find the issue it
was in). It was the equivalent of the CD .. and was at most a few hundred
bytes long. It certainly would have saved a lot of typing if Apple had
included it in ProDOS.
