Let me try again. We don't understand your use case. You didn't show us the definition of your dispatch function so we have to guess. Even so, It is hard to imagine a "legitimate" use with dynamically provided functions, particularly as the length values assigned to the existing built-ins don't follow strict rules. At the very least you need to help us understand why your use case is both reasonable and valid. Allen
