as68/as09 are 6800/6801/6803/6809 assembler on UNIX.
It outputs Motrola 'S format' object code.
To compile, set CFLAGS and DESTDIR in makefile appropriately.
as09 src_file [-O] [-v] [-s] [-o [obj_file]] [-l [lst_file]]
or
as68 src_file [-X] [-v] [-s] [-o [obj_file]] [-l [lst_file]]
-O optimize long branches to short (6809 only)
-l [file] output assembler listing
-o [file] output object code
-s output symbol table to the list file
-v turn on verbose flag
-X enable 6801 operation codes (6800 only)
listing file name can be explicitly specified with '-l' option or defaults to src_file.l.
object file name can be explicitly specified with '-o' option or defaults to src_file.o.
