 It's easier to pronounce. ;-)

+<I>Quote from FAQ in version 2.4, regarding 'final edition':</I><BR>
 Because I don't plan adding any new features. xasm is already a very
 sophisticated tool, much more powerful than Quick Assembler.
 Of course, it does not mean there won't be any new releases.

 <P><B>What about supporting other 6502-based machines, other processors (65816 etc.) ?</B><BR>
 xasm is not a universal 6502 cross-assembler. If you need a portable
 cross-assembler (and maybe even an excellent C compiler), then visit
