That was the key thing I needed to know.  Thanks.  It works, but I've
never seen it documented anyplace, so I'm a bit nervous about it.

Yes, I have understood the differences between volumes and devices since
around 1985, but I disagree with your comment about the status of df0:
being useless info.  If the user has included 'df0:c' in his path, I
need to bypass df0: if there is no disk inserted.  The user might well
do this instead of using the volume name to access the files in the 'c'
directory of whatever disk happens to be in df0: at the time, while c:
might point to the 'c' directory on his hard disk.

Anyhow, this new feature of ignoring offline parts of the path has been
added; it will appear in 1.3.  I also do that for some commands;  for
example, a 'cd df0:' will not produce the requester if there is no disk
in df0:.
