Well, that's why I'm confused.  I ran it literally just as I received it 
(didn't replace $dir with anything, just used it as-is) and it worked. 
 That's when I went looking for either 'dir' or 'DIR' in the environment 
and checked 'man find' to see if $dir had special meaning to the 
program.  Came up empty.  Then I tried Google and Yahoo only to find 
that they treat '$' special somehow and return way too many hits where 
$dir isn't even in the 'hit'.  At that point I turned to the group, 
still no answer to this point.  The speculation I'm toying with now is 
whether a dynamic variable is being created for the duration of 'find' 
and destroyed at program termination.  Even if this is true (maybe a big 
if) I don't have any idea how to confirm or deny it.
