In a position robot waits for three different inputs: $IN  OR $IN OR $IN
I defined three inputs like this:
SIGNAL choiise $IN to $IN
So after the WAIT command, I wrote this:
SWITCH just works for Case 1 related to $IN and for other cases program jumps to the DEFAULT. I think the problem backs to the number of the cases. maybe I must change the number 2 and 3 .
thanks for any help
