Thanks for your responses. I defined the variable with the ARGV, 
correct. I'm globbing PDFs just to see if there are any PDFs. If there 
aren't any, then, I exit the script. This script only works on PDFs, in 
that folder. I run this script, along with many, many other scripts like 
it, with a scheduling utility called ActiveBatch. I've told that 
scheduling utility to fire this script when there's one PDF, at least, 
in the folder. So, yes, the ARGV[0] stands for the one file at a time 
way of executing against one or more PDF files. Thanks.
