Can someone help me. I want to ask the user a question and then do something whether they say Yes or No.
I have tried a few ways but not really sure if i am close.
Thanks

Re: IF + user input

You mean you want to read a line of input from console like this?

  (if (string= (string-upcase (read-line *standard-input* NIL "")) "YES")
    (do-yes-stuff)
    (do-other-stuff))

OMG I would never guessed that was within the standard library

Wonder how diverse it has been implemented since it's parsing is in "implementation dependent manner"
