Sometimes an expression will print output during its execution. You
can indicate the printed output with the @print{}
command.
The @print{}
command is displayed as `-|' in Info and
as `-|' in the printed output.
In the following example, the printed text is indicated with `-|', and the value of the expression follows on the last line.
(progn (print 'foo) (print 'bar)) -| foo -| bar => bar
In a Texinfo source file, this example is written as follows:
@lisp (progn (print 'foo) (print 'bar)) @print{} foo @print{} bar @result{} bar @end lisp
