I tried arrayjob  a bit and it will work but it too will not accept  
numbers in names of commands. For instance,

	\newarray\Chapter13
	\readarray{Chapter13}{A&B&C&D}

does not work. Fortunately,

	\newarray\ChapterXIII
	\readarray{ChapterXIII}{A&B&C&D}

does.

Companion 2ed doesn't say anything about this so I assume that this  
is just something Lamport set and everybody (except me of course)  
just knows about it. Is this in his book?

P.S. The "more advanced" examples are truly awesome!
