Subject: A newbie question for using sort

I've been trying to use sort for an array and I seem to be missing 
something.  Here's my code and results.

#!/usr/local/bin/ruby

arr = ["a", "G", "b", "f"]
arr.sort
print "Sort #1\n"
for atom in arr
     print atom, "\n"
end

arr.sort { |x, y| y <=> x}
print "\n\nSort #2\n"
for atom in arr
     print atom, "\n"
end

[localhost:~/src/ruby] steve% ./dirsort.rb
Sort #1
a
G
b
f


Sort #2
a
G
b
f

What I'm guessing is that the item I think is an array is not actually 
an array or the comparison is working the way I think it is supposed to. 
  If anyone can let me know what I'm doing wrong, I'd appreciate it.

Thanks,

Steve
