Currently supported target machines are: 

• Apple ][
• Atari 8-bit (inc 5200), 2600 VCS, 7800

• TRS-80 Color Computer 1/2/3
• Nintendo NES
• MSDOS 16 bit
• Windows 64 bit (Windows XP - 11)
• Linux 64 bit
• Sinclair ZX81

Some are a little further along than others.  More will be added in the future.  Lots of example code is included to get you started.

• Compiles BASIC to native machine code for speed
• Options for speed vs size, carts, math libs, etc
• Flexible syntax at compile time with @REWRITE and @REWRITE_EXPR
• Modularity supported by @INCLUDE, pull in files and resources
• Portable APIs (TILE, SPRITE, FILE, GRAPHICS, CELL, IMAGE, INPUT, SOUND, etc) - write once and run multiple on systems
• Supports compiling old BASIC listings, including tokenized, even running on different systems!

Quick Start

@OPTION TARGET c64
CLS
POSITION 0, 0
PRINT "HELLO, WORLD!"

Build a runnable .prg in one shot:

crustybasic hello.cbs

Compile to assembly:

crustybasic compile hello.cbs -o hello.s

Full usage guide and language reference included as well as lots of example code.  Bug reports/feature requests can be posted here in the forums or at https://github.com/bsturk/crustybasic
