       Quick question: How does one control whether Symbolics NFS treats version
       numbers as foo.lisp.~1~ or foo.lisp.1

   I'm not sure I understand the question.  I think you're asking what it
   takes for Genera with NFS to parse a Unix versioned pathname (ending in
   .~<version>~) such that PATHNAME-VERSION returns something other than
   :UNSPECIFIC.  The answer is that if one of the directories in the
   pathname ends in ".sct", Genera expects all files to have version
   numbers, and parses the version number out.  If none of the ancestor
   directories have the ".sct" suffix, the file name is parsed the
   traditional way, so the version number ends up being treated as the
   type.

No this is not what I am asking.

   If you're talking about how NFS *creates* versioned files, if the server
   is Unix then it always uses ~<version>~; it will never create
   foo.lisp.1.

Yes this is what I am asking. On the local system that I am using here at
UPenn I see a different behavior than I have seen anywhere else. If I c-X c-S
a file foo.lisp several times, the files get *created* by NFS as foo.lisp.1,
foo.lisp.2, etc. *not* foo.lisp.~1~, foo.lisp.~2~, etc. This has screwed me
since I have SCT directories with version numbers in the ~ format and at UPenn
I can't read those directories. I seem to remember once coming across some
documented variables that specify the format strings used to convert NFS
pathnames into printed form which would allow control over the format used for
version numbers. I couldn't remember those variables though and couldn't find
them in the docs or with APROPOS. That is why I am asking SLUG.

   For details about both of these, see sections 3.3.1.3 UNIX Backup Files,
   and 3.3.1.4 Using SCT with a UNIX File System, in the Genera 8.1 Bundled
   Network Products Documentation manual (or in the Document Examiner).

Unfortunately we don't have Genera 8.1 and still use 8.0.1.
