Is there a way to set a timed pause in a LISP routine?

Is there a way to set a timed pause in a LISP routine?
Such as:

(defun c:PAUSE-TEST () ;PAUSE-TEST @ command line launches routine
(Command "-Layer" "Thaw" "1" "") ;Thaw Layer 1
;PAUSE FOR 3 SECONDS
(Command "-Layer" "Freeze" "1" "") ;Freeze Layer 1
;PAUSE FOR 2 SECONDS
(Command "-Layer" "Thaw" "2" "") ;Thaw Layer 2
;PAUSE FOR 3 SECONDS
(Command "-Layer" "Freeze" "2" "") ;Freeze Layer 2
;PAUSE FOR 2 SECONDS
(Command "-Layer" "Thaw" "3" "") ;Thaw Layer 3
;PAUSE FOR 3 SECONDS
(Command "-Layer" "Freeze" "3" "") ;Freeze Layer 3
;PAUSE FOR 2 SECONDS
(Command "-Layer" "Thaw" "4" "") ;Thaw Layer 4
;PAUSE FOR 3 SECONDS
(Command "-Layer" "Freeze" "4" "") ;Freeze Layer 4
;PAUSE FOR 4 SECONDS
(princ "\n\t Thaw 1-4 & Freeze 1-4 Complete") ;Comment @ routine completion
(princ) ;No Nil returned
) ;Ends PAUSE-TEST

The goal is to show 24 different options visually in sequence.

I think you can use Delay. To pause for 4 seconds:
(command "delay" 4000)

In BricsCAD LISP you can use the SLEEP function

:(sleep 3000)
T

Thank you very much guys.
DELAY worked, couldn't get SLEEP to work.
Odd thing though, it was inconsistant.
Canged routine 1 line @ a time to watch for errors.
Sometimes the 1st time I ran it, it went well.
Other timse it did not work right such as Layer 3 did not thaw.
But I found that if I run it again right after the bad run, it works. Not sure why there is some inconsitancy; does not ellicit confidence.
But will mess w/ it some more.
We shall see how 24 layers work.

(defun c:PAUSE-TEST () ;PAUSE-TEST @ command line launches routine
(Command "-Layer" "Thaw" "1" "") ;Thaw Layer 1
(Command "DELAY" "2000") ;Pause 4 seconds
(Command "-Layer" "Freeze" "1" "") ;Freeze Layer 1
(Command "-Layer" "Thaw" "2" "") ;Thaw Layer 2
(Command "DELAY" "2000") ;Pause 4 seconds
(Command "-Layer" "Freeze" "2" "") ;Freeze Layer 2
(Command "-Layer" "Thaw" "3" "") ;Thaw Layer 3
(Command "DELAY" "2000") ;Pause 4 seconds
(Command "-Layer" "Freeze" "3" "") ;Freeze Layer 3
(Command "-Layer" "Thaw" "4" "") ;Thaw Layer 4
(Command "DELAY" "2000") ;Pause 4 seconds
(Command "-Layer" "Freeze" "4" "") ;Freeze Layer 4
(princ "\n\t Thaw 1-4 DELAY 4 Sec.") ;Comment @ routine completion
(princ) ;No Nil returned
) ;Ends PAUSE-TEST

**Anthony & Jason, **
Awesome; 1st run on all 24 layers failed, locked after layer 3, ESC’d, ran it again, good.
Thanks a lot. Now I have to polish it up for show.
