1.3.4 Printing Notation

Many of the examples in this manual print text when they are evaluated. If you execute example code in a Lisp Interaction buffer (such as the buffer `*scratch*'), the printed text is inserted into the buffer. If you execute the example by other means (such as by evaluating the function eval-region), the printed text is displayed in the echo area.

Examples in this manual indicate printed text with `-|', irrespective of where that text goes. The value returned by evaluating the form (here bar) follows on a separate line.

(progn (print 'foo) (print 'bar)) -| foo -| bar => bar
