The sand Rkeys can also be used with variables. For example,

s +(in the MU%C menu) stores the rightmost number from the display into the variable M%C. R +copies the contents of M%C into the calculator line. If there is an expression in the display v(suchnumber.as $)+!), then the recalled number replaces only the last

You do not need to clear storage registers before using them. By storing a number into a register, you overwrite whatever existed there before.
