Parameter Mode might change the value of the corresponding

A parameter mode. Upon returning from a method
Clears call, a clears-mode parameter has the initial value for
its type.
The default parameter mode. Upon returning from a
Restores method call, a restores-mode parameter has the value
it had when it was passed into the method.
A parameter mode. Upon returning from a method
call, a replaces-mode parameter may have a different
Replaces value than its incoming value, but the method's
behavior doesn't depend on the incoming value of the
parameter.
