strcar doesn't work?

[Anonymous]

Dear All,

I am new in Lisp can you help find my problem please?

numlst is a group of number

(setq dcm (getstring "\nDCM Name: "))
(setq minn (apply 'min numlst)) <<<<< I believe this line has something wrong
(princ (strcat dcm "," minn))

error :bad argument type: symbolp nil

Many Thanks,

Bruce

"strcat" is working only for strings.

you need to convert the number to string.

refer "rtos" function.

(setq dcm (getstring "\nDCM Name: "))
(setq numlst '(1 2 3 4))
(setq minn (apply 'min numlst))
(princ (strcat dcm "," (rtos minn 2 0)))
