> So it should work on only the temp file, but I  want to get rid of the no-such-file warning on the purge, by putting the purge inside "IF FINFO('xx','exists')".  But finfo reports a perm file of that name if one exists and no temp file exists.  And yes, I know I can :purge xx, temp >$null, but I don't like to do that.


This seems to work:

   :file xx, oldtemp
   :calc finfo ("*xx", "exists")

Note the "*" in the filename given to FINFO.  If no temp "xx" exists,
I get "FALSE" regardless of whether or not a perm "xx" exists.
