  What's Next?

  In this course, you have learned how to use commands and operators in ObjectScript to create variables, manipulate them in a number of expression types, and destroy them when needed. You have also used branching and loops to make decisions about the manipulation of variables and other operations.

  Now that you know the basics, you can begin to understand how and when you can use ObjectScript to create and work with objects in InterSystems IRIS. This foundation will prepare you for writing your first InterSystems IRIS application.
