Markov chain with extras?

[temp at mclift.fsnet.co.uk]

Hi All,

Could someone show me how to do this?

I want to generate a list using a Markov chain, however, as well as
using the previous two items in the list to decide the current choice I
want the decision to be also dependant on an item at the current
position in another list.

I hope this explains thing clearly enough.

Thanks,

Malcolm
