\begin{abstract}
\noindent
This tutorial describes the definitional package for nonprimitively corecursive functions
in Isabelle/HOL. The following commands are provided:
\keyw{corec}, \keyw{corecursive}, \keyw{friend\_of\_corec}, and \keyw{coinduction\_\allowbreak upto}.
They supplement \keyw{codatatype}, \keyw{primcorec}, and \keyw{primco\-rec\-ur\-sive}, which
define codatatypes and primitively corecursive functions.
