Rob's proposal makes sense. A few comments:
1. Yup, use a keyword, namely :DIRECTION.
2. If we believe in :DIRECTION for PROBE-FILE, then we have to admit
that :DIRECTION :PROBE makes no sense for OPEN, because probing
is orthogonal to direction. I suggest we either add :PROBE T
as another keyword to OPEN, or, better yet, remove the feature
3. PROBE-FILE needs to tell me more. I want to know if I can't get
at the file because:
a) the file spec is bad.
b) the device doesn't exist.
c) the directory doesn't exist.
d) I don't have sufficient access privilege.
e) etc., etc.
The basic need addressed by Rob is a real one: Is this file spec good,
can I get to the file, and what can I do to it (read, write, etc).
