Dynamic return ?

[JohnnyCoffee]

I receive in a function two parameters (Class and Method) with dynamic values that serve to reference a certain class and access the method on the return of the function. Working with dynamic data I imagined something like this :

v_return = v_class + "." + v_method + "()"
return v_return

The problem is that I need to execute the return to call the class method retrieved in the parameter and not print the string on the screen :

Main.index()
