Are there any sample programs in lisp than can give more guidance than textbooks

[pguimber]

Hello,
ont the web you have many exemples and forum (in french but other in english...)
https://programmatio...ar-stendhal666/

https://cadxp.com/to...-lisps-de-gile/

See the Lisp of Autocad, it's same.

My little example to count blocks (it's not mine) :

;NBLOC

(defun c:NBLOC ()
(initget "O N")
(setq choix (getkword "\nDésirez-vous créer un fichier contenant le nombre de bloc ? O/N: "))

(setq bl (list (cdr (assoc 2 (tblnext "block" T)))))
(setq nombl T)
(while (/= nombl nil)
(setq nombl (tblnext "block"))
(if (/= nombl nil)
(setq bl (append bl (list (cdr (assoc 2 nombl)))))
)
)
(setq compte 0)
(setq nb (length bl))
(setq f (open (strcat (getvar "dwgname") ".nbl") "w"))
(repeat nb
(setq ent (ssget "x" (list (cons 0 "INSERT") (cons 2 (nth compte bl)))))
(if (/= ent nil)
(setq nbloc (sslength ent))
(setq nbloc 0)
)
(princ (strcat "\n" (nth compte bl) " = " (itoa nbloc)))
(if (= choix "O")
(progn
(princ (nth compte bl) f)
(princ " =  " f)
(princ nbloc f)
(princ "\n" f)
)
)

(setq compte (1+ compte))
)
(close f)
(if (= choix "O")
(princ (strcat "\nLe fichier contenant la liste des bloc se nomme: " (getvar "dwgname") ".NBL"))
)
(princ)
)
(princ "\n==> NBLOC")
(princ)

Hi, can you insert a screenshot of the result?

When i type the height i have this error: too many arguments.

Hello,
Sorry I gave this Lisp just to make an example of what you can find. I am an amateur in programming. But I will take a closer look ...
