 Well, this is changed in 1.8

pigeon% cat test.rb
p ARGF
pigeon%
 
pigeon% ruby -v test.rb test.rb test1.rb
ruby 1.8.0 (2003-03-03) [i686-linux]
test.rb
pigeon% 

 with 1.6, it was initialized to "-" and set to the right value after an
 access 

pigeon% cat test.rb
p ARGF
ARGF.gets
p ARGF
pigeon%
 
pigeon% /usr/bin/ruby -v test.rb test.rb test1.rb
ruby 1.6.8 (2002-12-24) [i686-linux]
-
test.rb
pigeon%

 ARGF give you the input stream read by the program

 ARGF#to_s is the same than ARGF#filename and give the name of the argument
 that ruby actually read
