A standard Caché installation includes a set of XML files containing Caché classes and CSP pages that accompany the tutorial's exercises and examples. The files are in install-dir\Dev\Tutorials\CSP. They can also be downloaded from here. Install the classes and CSP pages by importing them into Caché using Caché Studio:
Open Caché Studio and connect to the namespace in which you will be working (most likely USER). Click File > Change Namespace to connect to the desired namespace.
On the Caché Studio menu bar, click Tools > Import Local. Browse to the correct file. Click on the file and then click Open.
