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*) by typing
C-j after the closing parenthesis of the example, 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))
