Hi John,

As I look in the index of my pickAxe book for ARGF I notice that on page 219 
it says that it is a synonym for $<. So flpping back to page 217 explains 
that $< is a global IO variable that represents the contentation of the 
contents of all the files given as command-line arguements, or $stdin if 
there are no arguements present. Hopefully this helps you out.

Now that Christmas is over, I guess we move on to new years - happy new years 
all.
