The syntax of the AL language is designed to help building business applications for Business Central.

Tip

Use Ctrl+Space to trigger IntelliSense and get assistance on code completion, parameter info, quick info, and member lists. For more information about snippets, see Syntax and snippets.

In addition to the inline help of IntelliSense, you have access to various snippets that give you a template for a specific object type. Use a code snippet from an .al file by start typing the snippet name. All snippets start with the letter t. For example, to get a template for a table, type ttable and press Tab.
