14.15.4 @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
