Extracting a token from a String Variable

In Release 2.1.5.123 there is a new advanced feature in Rule Machine that allows you to extract a token from a string, including from a String Variable.

The index selects which token we want, starting with 0 for the left-most token. So, in this case, the result stored in Charlie would be 123. That's not very useful as sho…
