Here's a code snippet (picture) that does what you want. You could put this in your loop, or you could make it a subVI. If you make it a subVI to be used in multiple places, be sure to make it a reentrant subVI. That way it will allocate separate memory for each call. To make a subVI reentrant go to File>>VI Properties>>Execution and choose Reentrant execution.
