+<p><strong>Linked Lists</strong> are the standard containers for collections of like-type data on XCS.  They provide quick and easy ways to define and reference <em>lists</em> of numbers, letters, phrases, etc. Lists can contain any type and can be filled with different types, for example [1,2.74,"hello"] is a valid list with three different types.</p>
