concat a list of strings

concat a list of strings

[Andreas Seik]

Hello Newsgroup,

i just started to write some code in lisp.
now i want to concat a list of strings (name it stringlist) to one string.
(concat stringlist) will not work cause concat needs lists of chars not of
strings.
Do i have to write a loop by myself or is there a faster predefined way?

Thank You,
Andreas

(concat "hey you" " buddy") => "hey you buddy"

Don't know why you think it doesn't work.

Do not forget the mapconcat function  if you wish to introduce
a separator between the list elements.

As is probably clear by now, I misunderstood your question.
