This is what I mean:

if ($1 == !pick) { 
  msg $chan 12,1 $nick Spins the wheel.....!!  The Wheel Stops the ball number is:
  msg $chan 14,1 Ball - $rand(1,49)
}

This does exactly the same as your other 49 lines script.

You can also use $r(1,49), in stead of $rand(1,49). But that doesn't matter a lot.
