Rocket MV BASIC for Visual Studio Code Extension Feature Review: Formatting

I’m happy to introduce to you the Rocket MV BASIC for Visual Studio Code Extension Feature Review series!

In this series, I will cover useful features related to editing, compiling, and debugging using the Rocket MV BASIC for Visual Studio Code Extension. I’ll start by covering the editing feature, specifically formatting .


Reading legacy BASIC code can be challenging because different developers have different coding styles, and BASIC language grammar is so flexible.  The formatting functionality can help you unify the BASIC program style and improve readability.

·       “lowercase
·       “titlecase

All keywords and statements should have the same case.
