AutoLisp-Need help on Transparent commands

I need help on a little AutoLisp routine that I am writing
I want to :
1) Save the users layer in a variable called SAVELAYER
2) Change the layer to a layer called "GREEN"
2) Call up the Doughnut command
3) Then, after the user is finishd with the doughnut command, reset the
layer to the layer called SAVELAYER
Here is my code:
(defun C:insertdot ( / SAVELAYER )
(setq SAVELAYER (getvar "CLAYER" ) )
(command ".layer" "S" "GREEN" "" )
(command ".donut" 0 0.75 )
(command ".layer" "S" SAVELAYER "" )
) ; end defun inserdot
The problem is that when the doughnut command is called up, my program does
not wait for the doughnut command to run untill the user hits the escape
The program tries to run on through to the (command ".layer" "S"
SAVELAYER ) line and I
get an error.
Anybody know how to get my program to wait until the doughnut command runs
the rest of the code runs?
Thanks Jarv
(I also have this problem in a routine I tried to write where I call up the
"adcenter" function )

The fact that the donut command needs a break to end is troublesome in this routine. I'm not sure how to stop it without stopping the whole routine. Adding a pause at the end of the donut call will only work once and then the routine will fail when you feed it a command call when it's looking for a point. Have you thought about using ENTMAKE to make the donuts instead of using a command call? Then you could form a loop, and each time the user picks a point, you make a donut centered there.

(defun c:dnut(/ oldlayer) (setq oldlayer (getvar "clayer") oldecho (getvar "cmdecho")) (setvar "clayer" "0") (setvar "cmdecho" 1) (command "donut" "" "") (while (> (getvar "cmdactive") 0) (command pause) ) (setvar "clayer" oldlayer) (setvar "cmdecho" oldecho) (princ) )

I didn't know you could issue pause without quotes to the command call. Very cool. Is there anything else that will pass the command call I should know about?
Here it is in context:
(defun C:insertdot ( / SAVELAYER ) (setq SAVELAYER (getvar "CLAYER" ) ) (command ".layer" "S" "GREEN" "" ) (command ".donut" 0 0.75 ) (while (> (getvar "cmdactive") 0) (command pause) ) (command ".layer" "S" SAVELAYER "" ) )
