The Works > Values menu lets you perform operations on the results of the last expression entered at the Listener prompt. The values returned from this expression are referred to as the current values .
The menu is not available if the most recent input was not a Common Lisp form. This is because the evaluation of the last expression entered must have produced at least one value to work on.
The Works > Values menu gives you access to the standard action commands described in Performing operations on selected objects.
Note that the most commonly used of the standard action commands are available from the toolbar. For instance, to inspect the current values, click the 
button.
