The second chapter gave a more detailed overview of a topic started in Chapter 1, Getting Started with the NAV Development Environment. We learned to create codeunits, structure C/AL code into functions, pass parameters to functions, and use return values. The first examples illustrating C/SIDE capabilities were of a somewhat abstract nature, but closer to the end of the chapter, we learned how to use the database and discussed a more business-related scenario.
In the following chapter, readers will not only learn to use Record variables, but will complete a walk-through example of creating a custom table and writing table triggers.
