Next steps

Here are pointers to learn more about Teracloud® Streams.

In this tutorial, you learned about many topics superficially. Along the way, you saw several links to more detailed documentation. A good way to continue learning the language is to exercise by writing programs of your own. Table 1 lists several suggestions for topics you might want to study further, and exercises you might want to do to cement your SPL skills.
