### 13.9.4 `@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 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
