The (run-until-halt) function is documented in the manual; see
http://herzberg.ca.sandia.gov/jess/docs/functions.html#run-until-halt .

RU.SLOT was an internal type; the only mention of it in the Jess 5
manual is this line in a table:
final public static int SLOT = 16384; ; (internal use)
In Jess 6, it no longer even exists. If you want the ntype slot to
hold an atom, use RU.ATOM; if a String, RU.STRING.

Jess doesn't use the Observer interface. The manual (Jess 5 section
4.10) discusses using event listeners at some length.
Do you see a common theme to these answers? Not to be rude, but maybe
you need to make a cup of tea, put your feet up, lean back, and read
through the whole manual once.
