How to add radius

I've a program,but I am not satisfying,I would change the "rad" to become
simple and then the user give an input
(setq n (fix (getreal "\nENTER MAXIMUM RADIUS: ")))
(setq cn 0)
(setq rad n)
(setq rad (cond ((> rad n)(setq rad (.............
................................
(setq rad (1+ cn)

Hi, Ade!
If I see you trouble right, may be:

Code:

(defun c:ace (/ cnt loc n rad ss ssn)
(setq	n   (fix (getreal "\nENTER MAXIMUM RADIUS: "))
rad 0
loc '(10 10)
)
(while (<= (setq rad (1+ rad)) n) (vl-cmdf "_.circle" loc rad))
(setq	ss  (ssget "x" '((0 . "CIRCLE")))
cnt -1
)
(while (setq ssn (ssname ss (setq cnt (1+ cnt)))) (entdel ssn))
(princ)
)

or more effective vla- code:

Code:

(defun c:ace1 (/ actdoc cnt key loc n rad space ss ssn vloc)
(setq	actdoc (vla-get-activedocument (vlax-get-acad-object))
space  (pl:get-space actdoc)
n      (getint "\nENTER MAXIMUM RADIUS: ")
rad    0
loc    '(10.0 10.0 0.0)
vloc   (vlax-3d-point loc)
)
(while (<= (setq rad (1+ rad)) n) (vla-addcircle space vloc rad))
(initget "Yes No")
(if (or (= "Yes" (setq key (getkword "Erase circles [Yes/No] <Yes>: "))) (not key))
(progn (setq ss  (ssget "x" (list '(0 . "CIRCLE") (cons 10 loc)))
cnt -1
)
(while (setq ssn (ssname ss (setq cnt (1+ cnt)))) (entdel ssn))
)
)
(princ)
)

(defun pl:get-space (doc)
(if (and (zerop (vla-get-activespace doc)) (= :vlax-false (vla-get-mspace doc)))
(vla-get-paperspace doc)
(vla-get-modelspace doc)
)
)

Best regards!
