Summary
This module discussed the basics of using the application language (AL) programming language. You learned about the difference between identifiers, syntax, and variables. You also learned about the difference between local and global scope variables.
Additionally, you discovered the different available data types in AL, including simple and complex data types and how you can define an option, but that it's better to use the Enum object instead.
You learned about the three collection types in AL: Array, List, and Dictionary. You need to define how many items are available in an array up front. List and dictionary are dynamic lists that can expand and shrink as needed.
The assignment of variables and the type conversions between two data types was also discussed, where you looked at the different expression types and operators and their precedence effects.
