In order to put together a description of the Diskcomm file format,
I had to disassemble the Diskcomm program.  The program consists of
three major portions of code.  The code is scrambled, probably to
prevent people from changing the screen displays with a sector
editor or similar program, as was often done in those days by
hackers and crackers.  I left out the opening screen in the source,
since that was not needed to obtain the relevant source code.
The OBJ files are the unscrambled versions.  You can find the
XL disks in the STACK directory.
