That is a very good question! I'm sure Carey or Pegasus or one of the other
old-timers will have the definitive answer, but in the meantime I'll try my
hand. I was always under the impression that a file, say a Word document
created on a PC, can be read by Word on a MAC because a .doc file is a .doc
file no matter what operating system it was created under. But now that
I've just thought of that, I'm having second thoughts. I am very likely
(most probably) wrong. Good luck, one of the real group aces will be able
to help you out.
