Welcome to XC=BASIC 3

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

  • Commodore-64
  • Commodore VIC-20
  • Commodore-16
  • Commodore Plus/4
  • Commodore-128 v3.1
  • Commodore PET series v3.1

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.

Language characteristics

  • 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”.
