1.3.4 Evaluation examples

The symbol “=>” used in program examples should be read “evaluates to.” For example,

     (* 5 8)                                ==>  40

means that the expression (* 5 8) evaluates to the object 40. Or, more precisely: the expression given by the sequence of characters “(* 5 8)” evaluates, in the initial environment, to an object that may be represented externally by the sequence of characters “40”. See section External representations for a discussion of external representations of objects.
