Command line options
DASMx
has the following command line options:
-a
generate assembler output (default is to generate a full listing file);
-c
TYPE set the CPU processor type – overrides any cpu statement in the
symbol file, where TYPE is one of the types reported by the
-l
option (6800, 6809, 6502, Z80 etc.) (default is 6800);
-e
NNNN specify a code entry point NNNN for threading;
-l
list all processors supported and exit;
-o
NNNN set the origin, or start address to NNNN (default is top of address
space less the length of the source image);
-t
perform code threading (requires at least one code entry point to
be specified);
-v
display version information and exit;
-w
wide listing format (shows instruction cycles and up to 8 data
bytes per line).
When specifying addresses, the number NNNN should be specified using C
language conventions (i.e. default is decimal, prefix with 0x for hex, prefix with 0
for octal).
Input files
The primary input file is a binary image of the code/data to be disassembled. This
must be code for one of the supported microprocessors (or other manufacturer
equivalent).
DASMx
will produce meaningless output for any other type of
processor.
DASMx
assumes a file extension of ".bin" unless otherwise specified for the binary
image file.
DASMx
looks for a symbol file of the same base name as the source binary file, but
with a ".sym" file extension. If a symbol file is found, it will be used. Provision of a
symbol file is optional, except where code threading is used (where a symbol file
must be used to define at least one code entry point).
