#### 1.3.3 Printing Notation

Many of the examples in this manual print text when they are evaluated. In this manual the printed text resulting from an example is indicated by ‘`-|`’. The value that is returned by evaluating the expression is displayed with ‘`⇒`’ (`1` in the next example) and follows on a separate line.

         printf ("foo %s\n", "bar")
              -| foo bar
              ⇒ 1
