Use the CerComp Source III as a model. This disassembler has a fast mode 
which works like the EDTASM debug, but it also has a full mode which 
saves the created source to disk as an .asm file.

The best thing about this program is that the user can enter addresses 
for blocks of fcb, fcc, and skip. The full mode will then take the byte 
table into account during disassembly. The byte table can be saved to 
disk so that multi-session disassemblies are possible.

The program has ascii and hex dump window to facilitate creating the 
above byte table.
