To be specific, it's in William Pokorny's "ObjectAslso" file from Sept. 19 2009,
if you would like to take a look (no pressure, of course.) In his file called
"ObjectAslso.inc", there is a function argument called 'S'.  I have a hard time
following the code because of its complexity, but I can't see where one (or
more) of the instances of that argument are assigned a value of any kind. I
could be wrong *of course*; maybe I'm just not seeing the forest for the trees--
or vice-versa!
