	John, or Dan,
I guess the first program every one writes is Yet Another Backup (YAB tm of
CovertWares!!!). Anyway, I too am writing a very specific type of backup program.
I had planned to use the READ/WRITE-READ/ONLY flag as a kind of backup flag. A
un-backed up file would be RW but after I copy the file to floppy I would make it
RO. That is because I was under the impression that TOS 1.0 and TOS 1.2 don't
support a real backup bit. I have looked in my MWC manual (3.09) and there is
no indiciation of a backup bit. Bit 5 (0x20) according to MWC in Fattrib()
is "written and closed". I guess that could be used as a backup bit, but it
isn't visible to the desktop. I normally use UIS2, and READ ONLY flags are
shown with a check mark, so they become visible (at least with UIS2). That was the
major reason why I was planning to use the READ/WRITE flag as a backup flag.

Is there a better way??
