Yeah, yeah - I've studied the bash man page (and what Google offers

This I will have to chew on and study with the resources until I 
understand what you are saying...  From what I can tell of the script, 
$_property is never empty at this point.  I've been stepping through

Thanks.  Oh, in case you couldn't tell, I'm a hobbyist.
