If you use the POSIX shell instead, you can

   $ mv OLDFILE  OLDSAVE
   $ mv NEWFILE  OLDFILE

(or some variation on that theme).  This has the
advantage of keeping the old file around (and visible)
for those currently accessing it, but moving the
new file into production for new users.

(I have no idea if it would work any better for SLs.)

Then again, for reasons unknown, I grok this solution,
but somehow have not assimilated the MPE equivalents.
Thus, there may be an MPE equivalent, but it's just not
as "obvious" to me.

I first saw this solution in John Burke's "Hidden Value"
column in The 3000 NewsWire awhile back.
