call-by-value
     
        (CBV) An {evaluation strategy} where arguments are evaluated
        before the function or procedure is entered.  Only the values
        of the arguments are passed and changes to the arguments
        within the called procedure have no effect on the actual
        arguments as seen by the caller.  See {applicative order
        reduction}, {call-by-value-result}, {strict evaluation},
        {call-by-name}, {lazy evaluation}.
