Stop Lengthen command repeating.

[Dayananda]

I have following code to draw a line first and adjust the length of line using LENGTHEN command. Only after getting entity name I need to change its property etc. But the I cant stop the lengthen command and it repeating. Please explain me what is mistake in my command.

(defun C:test1()
(setq p1 (getpoint"\npick point1"))
(setq p2 (getpoint"\npick point2"))
(command "line""non"p1 "non"p2 ""); bottom bar
(command "_lengthen" "DYnamic" "non"p2)
 (setq line1 (entlast))
 (command "change" line1"""P""C""1""");
)

I don't think I have used lengthen in a LISP,  not used the command for a while, but a quick look at your code "non"p2) - add a couple of spaces for readbility, but in that line you haven't specified the line to lengthen and you might need to end with "":

(command "_lengthen" "DYnamic" "non" p2 (entlast) "")

Maybe it is possible to change the order of commands, at first  "_.change", then "_.lengthen" ?

(defun C:LineChLenDY ( / p1 p2 line1)
  (setq p1 (getpoint "Specify the first point: "))
  (setq p2 (getpoint "Specify the second point: "))
  (command "line" "non" p1 "non" p2 "") 
  (setq line1 (entlast))                    
  (command "change" line1 "" "P" "C" "1" "") 
  (command "lengthen" "DYnamic") 
  (princ)
)

Use (list (entlast) p2) at place of p2: (list (entlast) p2) <=> at return of (entsel)

(defun C:test1 ( / p1 p2 line1)
	(initget 1)
	(setq p1 (getpoint "\npick point1"))
	(initget 1)
	(setq p2 (getpoint p1 "\npick point2"))
	(command "_.line""_non" p1 "_non" p2 "")
	(setq line1 (entlast))
	(command "_.lengthen" "_DYnamic" (list line1 p2) pause "")
	(command "_.change" line1 "" "_Properties" "_Color" "1" "")
	(prin1)
)
