How to check if function module exist

[Former Member]

Hi All!

Does anyone know how to check if function module, which name is provided by the user, exists?

I have to execute a function but when user provides a incrrect name - i receive a short dump. I would like to chceck if this function exists before execution and if not - warn user with message box.

Thanks
