Introduction
Dynamics 365 Business Central and AL language contain many built-in functions that you as a developer can use during your development projects.
These built-in functions called interaction functions, can help you interact with the user, show a message, or request confirmations.
This module explains how to use functions to work with string values, numeric values, and dates. Also, built-in functions for arrays and lists are discussed.
You can convert a text data type into a code data type and an integer into a decimal data type, but you can't convert an integer into text or text into a decimal. Therefore, you'll also learn about some variable functions like Format and Evaluate.
Numerous system functions can help you identify a user, a company, today's date, or a time that can be used when you're coding.
