__mvPrivate( <variable_name> )

This function can be called either by the harbour compiler or by user. The compiler always passes the item of IT_SYMBOL type that stores the name of variable. If a variable with the same name exists already then the value of old variable is hidden until the new variable is released. The new variable is always initialized to NIL value.
