#### 1.3.3 Printing Notation

Many of the examples in this manual print text when they are evaluated. Examples in this manual indicate printed text with ``-|`'. The value that is returned by evaluating the expression (here `1`) is displayed with ``=>`' and follows on a separate line.

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