Hi Jon, thank you for your mind reading! :::))) Exactly! Now I know, that racket passes references under the hood and the world is getting a better place again. Cheers Meino Jon Zeppieri [16-11-01 04:40]: > On Mon, Oct 31, 2016 at 11:28 PM, wrote:

Hi Meino, Good news! There are built-ins that will do almost all of this for you: On Mon, Oct 31, 2016 at 10:53 PM, wrote: > Hi, > > I have a lng list of something. And I have a recursive serach > function to crawl down the list and search for a previously determined
