# Welcome to twinBASIC

twinBASIC is a new BASIC language and development environment aiming for 100% backward compatibility with VB6 and VBA, while adding modern language features --- generics, native **Interface** and **CoClass** declarations, attributes, and a package system. The compiler and IDE are under active development and currently in beta; the [FAQ](FAQ) covers the project's status, authorship, and what is and isn't implemented today, and downloads live on the [Releases](https://github.com/twinbasic/twinbasic/releases) page of the main GitHub repository.

## New to twinBASIC?

Start with the [FAQ](FAQ) for orientation --- what twinBASIC is, where it stands today, and what runs on it --- then the [Features overview](Features/) for a tour of everything the language adds on top of VBx. The [Tutorials](#tutorials) section below has step-by-step guides; the [Arrays](Tutorials/Arrays) tutorial assumes no prior twinBASIC experience and is a reasonable first read.

## Coming from VBA or VB6?

Most existing VB6 / VBA code compiles unchanged. The [Features overview](Features/) catalogues every addition --- new data types (**LongLong**, **LongPtr**, **Decimal**), native **Interface** and **CoClass** definitions, **Implements Via** and **Inherits**, generics, method overloading, type inference, attribute syntax, and more. The reference pages flag each twinBASIC-specific deviation from VBx inline with a `> [!NOTE]` callout; most VBA-derived pages are adapted from the Microsoft VBA-Docs sources and remain compatible word-for-word where the semantics did not change.
