What is @SK

Then you don't need to concede anything to George.

What you need to do is run off and *fix the documentation*.

Back in 96, when I reimplemented Multifile to use indexes instead of
doubly linked lists (so it wouldn't, y'know, break every 5 minutes), I
knew this, because I (now) remember having to do "sk=@sk" on the first
line of my @wlf routine (and I think this might have even predated "wlf*";
when did that happen?)... but I didn't remember it now, and the documentation
didn't say so at either time.
