How can I get an array of variables in a formula?

[Flamboyant]

I am trying to build a calculator using the Eval Multi-Variable Array.vi function. For this I need to get an array of variables present in the formula. Can someone give me a vi which will list all the variables present in the formula? Variable could be anything. The seperation between two variables will be the mathematical operator or brackets.
