  Originally posted to comp.sys.m6809 by Didier Derny (didier@aida.remcomp.fr)

  Minor hacks by Alan DeKok

 Fixed: D_Indexed addressing used prog[2] and prog[3] when it meant
        prog[pc+2] and prog[pc+3]:  Would produce flawed disassemblies!

        changed addresses in D_Indexed to be all hex.
	added 2 instances of 'extrabyte' in D_Indexed: would not skip them..
        Added PC offsets to D_Indexed ,PCR formats
	added SWI2 print out as OS9

  To do:

 handle command-line options properly...

 Fix handling of illegal opcodes so it doesn't skip a byte
   i.e. $87 is a skip 2

 Move defines to another file

 Add 6309 support
   also add 6309 native-mode support, and listing of clock cycles for opcodes.

 Add OS-9 support

 add proper label-disassembly.  i.e. 2-pass.
