I want to know how to create and write a text file in lisp. I just want to write a simple line, for example:

I am using the LispWorks IDE in window 7

Answer 1

 (with-open-file (str "/.../filename.txt" :direction :output :if-exists :supersede :if-does-not-exist :create) (format str "write anything ~%")) 

You can also select various settings for the with-open-file macro. If you use :append instead of :supersede , then you can write to a text file while maintaining its context instead of replacing the available content.
