Title: Add string to predefined List
Post by: vincent.r on September 05, 2017, 02:36:54 AM

I am newbie to autolisp, I am trying to add a string "MVTTPL-101-DB-11_1" to a predefined list i.e. (setq shrirfi '(fnames)).
I have googled this but could not get solution ? Can anybody help ?

>> (setq shrirfi '(fnames))

What is fnames? string, list, ...?

Maybe:

Code: [Select]

Comando: (setq shrirfi '("fnames"))
("fnames")

Comando: (setq shrirfi (cons "MVTTPL-101-DB-11_1" shrirfi))
("MVTTPL-101-DB-11_1" "fnames")

Comando: !shrirfi
("MVTTPL-101-DB-11_1" "fnames")

It works great. Thanks Marc'Antonio Alessi. I was trying with append function, now I will use reverse.

Thanks again for your quick reply.

If you don't want to reverse your list just use append as you mentioned: (append shrirfi '("MVTTPL-101-DB-11_1"))
