Look at your self :
"I know what a jump table is .
I know what a binary search is..
whoo hoo look at me.
I have my own scripting language..
whoo hoo I am super everyone look how great I am."

When are you going to stop pretending to be some kind of expert?
You are a proven idiot scorned and this is just another twisted 
misinterpretation of my post. I was not discussing the way a compiler 
implements/optimises a switch case at machine level code, my post was a 
philosophical view of the numbers, and how 525 may initially seem alot but 
when you think about it its not much really.

If you wanted to discuss how the switch case is implemented by the compiler 
why did you not reply to that part of this disussion?
