Here's a nice little lisp code if you have ever had the issues of having your osnaps reset when you escape out of a lisp routine that doesn't have an error trapping routine. The only tweak that you have to make is where it says "NUM" in the lisp code. This should be a number based on your osnap mode. To find this number for you should set your osnaps the way that you would normally have them and then type in "OSMODE" at the command prompt.
(defun c:rs ()
(command "_osmode" "NUM"))
The number in the "<>" is the number that you need to insert where "NUM" is in the lisp code. For example, if the number is "<183>" then you would see this...Code:
(defun c:rs ()
(command "_osmode" "183"))
