XC=BASIC is a cross compiled, modern BASIC programming language for 8-bit Commodore (and alike) machines, such as

• Commodore-64
• Commodore VIC-20
• Commodore-16
• Commodore Plus/4
• Commodore-128
• Commodore PET series (with limitations)
• Commander X16 (beta) ¹⁾
• MEGA65 (beta)
• The GameTank console (GameTank BASIC SDK is built on XC=BASIC)

It compiles BASIC source code to fast machine code. Although not 100% compatible, its syntax was designed to be similar to that of QuickBASIC and CBM BASIC.

• Statically typed - 7 data types for different purposes.
• Advanced control flow statements.
• Local, global and shared scopes.
• Static or recursive subroutines and functions, forward declaration, overloading, etc.
• User-defined types with methods - similar to OOP classes.
• The runtime library depends on KERNAL only, BASIC ROM is banked out while running.
• Extensible through libraries.

The term “XC=BASIC” stands for “Cross Compiled BASIC”.

• Download latest stable: v3.1
• Download v3.2.0-beta with MEGA65 and Commander X16 support
