Look into using vl-catch-all-apply

 

Please remember to use code tags...

Sorry, thought it was only for use in large codes, I will do next time.

 

Do you have a simple example of vl-catch-all-apply ?

The examples I found on google are as difficult to understand much.

 

Thanks

Silly example:

 

(defun c:test ( / num result )
   (if (setq num (getint "\nChoose a number... just not zero: "))
       (progn
           (if (vl-catch-all-error-p (setq result (vl-catch-all-apply '/ (list 10.0 num))))
               (princ "\nI told you not to choose zero!")
               (princ (strcat "\n10 / " (itoa num) " = " (rtos result 2)))
           )
       )
   )
   (princ)
)
