High-speed, two-pass portable 6502 cross-assembler

xa is a high-speed, two-pass portable cross-assembler for the 6502 CPU with a C-like preprocessor. One of several popular 65xx assemblers, xa is written in C and released under the GPL-2. It has been in continuous development since 1989. Other tools in the xa package are: * file65 - a tool for printing information about o65 object files. * ldo65 - a linker for o65 object files. * printcbm - a simple CBM BASIC detokenizer similar to the far more powerful petcat proviced by VICE. * reloc65 - a relocator for o65 object files. * uncpk - a c64 cpk archive manager.
