F# break from while loop

Question

There is any way to do it like C/C#?

For example (C# style)

for (int i = 0; i < 100; i++)
{
   if (I == 66)
       break;
} 

Answer 1

You have to change it to a while loop.

let (i, ans) = (ref 0, ref -1)
while(!i < 100 and !ans < 0) do
 if !i = 66 then
   ans := !i
ans

(This breaks when i gets to 66--but yes the syntax is quite different, another variable is introduced, etc.)
