     I've been told that somebody published a note, explaining how to catch
errors, and give the user a chance to recover, before bailing out of the
program.  I'm thinking of things like drive door being open, drive being
read only, etc.  Along the same lines, I'd like to put together a disk backup
utility that would not let the user format the source disk, and then wait to
copy the blank one onto it.  If the disk has been erased with a tape eraser,
there is no directory to check for.  I'm looking for these to be truly bullet
proof, if there is ANY chance of error, the user may be better off without
them.  (All this is targeted for a Zenith Z89 with 2.2.03 CPM, if that matters)
Many Thanks in Advance
