What is returned by a funktion if the returnvariable has no name and no call to EXIT() is made in the function?

I have a function that returns a boolean with no name. Previously the code included a call to EXIT() that defined whether the value returned sould be true or false. Now that the call to EXIT() has been removed what is returned? Is the returnvalue going ti be always TRUE or always FALSE or maby random?

    A random value :-D :-D that would be funny

    It gives back the initial value of the datatype. On Boolean it is false.

    If the returnvariable has a name like "ReturnBoolVar", an it is set in the function, the exit returns the value of this variable.
    If the returnvariable hasn't a name and in the exit() is nothing set, it's returned the initial value.

    I will rather wrote that it will return "UNDEFINED" value. That this value is same as default value of the data type is just coincidence. Do not rely on it.
