The ??OL (Display Label and Paths) command displays the label and path information for peripheral devices. If the response to this command requires more than one screen, the system displays the screens at 8-second intervals.
Syntax

Explanation
??OL <device type> <unit number list>
Displays the label and path information for the devices.
Considerations for Use
This command is the same as the nonprimitive OL (Display Label and Paths) command, except that it is executed by a stack independent of the CONTROLLER stack. This command can therefore be used even when the CONTROLLER stack is suspended. For details about the information displayed, refer to the OL (Display Label and Paths) command.
