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
  • Commodore PET series
  • Commander X16 (beta) 1)
  • MEGA65 (beta)

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.
