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
follows on a separate line with ‘⇒’.
(progn (prin1 'foo) (princ "\n") (prin1 'bar))
⊣ foo
⊣ bar
⇒ bar
