 \item Added some structure (new chapters) to the document for inclusion of information about the "other" processors and machines. Started to separate the machine from the processor into separate sections. Should we do an all-in listing of opcodes for all processors, like for the 6502?
 \item Removed malformed coments examples as they are no longer applicable

+Declare data in the current segment.  No output is generated if within a uninitialised \mono{.U} segment. The byte ordering (the endian order) for the selected processor is used for each entry. It is possible to "swap endianness" (the byte order of wide-characters) using \mono{DC.s}
 
 The default size extension (\mono{.B}, \mono{.W}, \mono{.L}) is \mono{.B} (byte).
