Moderators Melba23 Posted February 17, 2018 Moderators Share Posted February 17, 2018 Au3Builder, It can help ensure you scope your variables correctly. The Variables - using Global, Local, Static and ByRef tutorial in the Wiki is a good place to start to understand why this is important.

TheDcoder Posted February 18, 2018 Share Posted February 18, 2018 Not to mention that it can be used to enforce variable declaration (a good practice) in projects with multiple contributors.
