A REF Parameter must be initialized before calling the function, whereas an OUT parameter does not.

Ref - the variable must be initialized before calling the function and will be modified by the called function.

Out - the variable does not need to be initialized before calling the function and will be initialized inside of the function.

A good example in the following link:
