14.10.4 @print{} (-|): Indicating Printed Output

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 HTML and (similarly) as a horizontal dash butting against a vertical bar 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
