I am attempting to call a function inside an object. But the function doesn't exist inside all objects that are run through the function. PIKE throws a runtime error of "Attempt to call the NULL-value". Is there any way to override this and have PIKE return a 0 instead. Or are there any other means of checking to see if the function exists inside the passed object? The function exists in more than one different object so I am not sure function_object() will work in this instance since it exists in more than one object. Any ideas?
