You can use the SRXMISSING command from our updated srxText utility.

A quick and dirty sub, but this will return any missing values in a list of numbers with a specified increment.

(defun foo (numberlist inc / low high i lst)
  (setq low  (apply 'min numberlist)
        i    low
        high (apply 'max numberlist)
  )
  (foreach x (cdr (vl-sort numberlist '<))
    (if (/= x (setq i (+ inc i)))
      (setq lst (cons i lst)
            i   (+ inc i)
      )
    )
  )
  (reverse lst)
)


eg.
(foo '(1 3 5 6 7 5 8 9) 1) -> (2 4)

I am not aware of any. But you can export the texts (or attributes) to a text file, sort it, and find any gaps.]]> Tue, 29 Mar 2011 15:00:11 +0000 https://www.cadforum.cz/forum_en/forum_posts.asp?TID=5605&PID=14460&title=lisp#14460 <![CDATA[lisp : actually i have parcelnumbers...]]> https://www.cadforum.cz/forum_en/forum_posts.asp?TID=5605&PID=14458&title=lisp#14458 Author: vasuchowdary200
