Subject: beginner iterators question

Hi,

I am brand new to ruby and liking it so far - particularly the watir 
test libraries. I am comfortable with the Java for loop syntax (i=0, 
i<4, i++) and haven't found something in ruby that feels as elegant, 
particularly when I want to use an increasing value i within the loop. 
Here's an example (with my limited ruby)

        i=0
        0.upto(3) do                              
            puts 'try number ' + i.to_s        
            i = i+1                                     # is there a 
more elegant way to do i++ ?
        end

I am guessing that ruby provides a more elegant way to do the above. I 
would love recommendations both on how to iterate when I want to use the 
changing value of the iterator in the loop, and how in ruby to do i++. 
Is there a way with upto() to use the current value during iteration? or 
another iterator where that is possible without needing to define i 
seperately?

Thanks in advance,
Jeff Fry
