Thank you for the reply.  The syntax-highlighter highlights the "for" 
and the "end" which are both on the left most edge of the block.  I like 
that because it saves me time scanning my code since I don't have to 
scan to the right to realize it's a block.

I might use the "for number in (1..5).to_a.reverse" variation of the for 
that Harry suggested below.

I just thought it was strange that the for couldn't do the BASIC style 
step -1 and the Ruby docs didn't seem to discuss it that I could find.

Thank You!
