I did attach that; but here goes again in case something stripped it
off. If it doesnt make it let me know and i will post a URL instead.
1) while-init-dis is for case 1 where c is initialized
2) while-noinit-dis is for case 2 where c is not initialize
3) while-nop-dis is for case 3 when you have nop thrown in.
cheers,
