Yes, that's about right, use something like

         Locate_Pointer^.code:= w;

where w is a word read in using something like the example code Marco 
pointed you at a couple of days ago (if there's something you don't 
understand in that I suggest raising it in that thread, rather than 
starting another one).

Remember that you'll need to allocate each record with the next pointer 
set to nil, and will also need to deallocate each one precisely once 
when it's no longer needed. In practice most people would use a more 
recent structure such as a TList, TStringList etc., what you've got 
there is rather 1970s code and since then there's been consensus that 
programs don't have to be written by reimplementing Lisp.
