AutoCAD Visual LISP / AutoLISP :: Place A Line Behind Other Items

I have a lisp file that reads in a point list from a text file and creates a number with a circle around it for every point, then a line from one circle to the next in line with the center point of each circle. Is there a simple way of making the lines "go behind the circles". The portion of code that creates the circles, lines and text is as follows and a cutout screen dump of what it looks like is below.

(setq amount 0)
(foreach item lines
;;;                                                              ;;
;;;  Create the text                                             ;;
;;;                                                              ;;
 (setq x (+ (atof (nth 2 item)) (car pt_origin)))
 (setq y (+ (atof (nth 3 item)) (cadr pt_origin)))

[Code]....
