Well, you could start by reading the documentation for the (reset)
function (manual section 8.115 in Jess 6.x manuals) and the discussions
of the knowledge base in section 2.7 and rules in 2.8.
In this specific case, the reset is important because there's a rule
"startup" with an empty left-hand-side. As the manual says:
We see first of all how issuing the reset command asserts the fact
(initial-fact). You should always issue a reset command when working
with rules.
The reason for this is that many rules depend on the presence of
(initial-fact) to fire -- and among these are rules with empty LHSs.
