Poke around http://www.abwillms.demon.co.uk/ it's there somewhere (one
or two levels).

That one had me stumped for a day or two.  All my code fit on the first
track, 
but the data went into lulu land and caused all sorts of weirdies to
occure (my 
system tables were built at compile time).

I will soon be posting my updated code to Alaric (maybe even today,
depends on my
modified djasm).  It has the above bug fixed and a much better demo
program.
