No, the problem is it _DOES_ execute the WHILE; you've made an infinite
loop. As there's nothing inside the WHILE...END that will ever change
the value of C2, the condition C2==0 if true to be in the IF to begin
with will never, ever become false.

As seen above, you don't need WHILE at all to solve the problem, the
search across the values of your vector is being done by FIND
automagically--that's the point of using it.
