Wow,
     I'm suprised that you would post code to the net looking like that!!
     (Actually, I'm suprised anyone would write code that looked like that.)
     Why did you do that?
     Is a <cr> keystroke really that much more expensive than a <sp> keystroke?
     
     Oh wait!!! I've got it!!  You crunched up some beautiful code just to 
     conserve net bandwidth and allow the display of the entire program on one
     screen!  Thanks for the thought, but I suspect resources aren't running 
     that short yet!!

     I'm glad I figured that one out....
