# Hi David,

# I'm going to go out on a limb here and assume you can't because that

That's right. You do not need such method. Everywhere You could call the
method You would type the variable name by Yourself. When a variable is
used as actual parameter to a function call its value is assigned to
another variable ( the formal parameter of the function ). The value
itself does not have a name.
