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
Rodrigo

Silly example:

copy

(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))
