But I think he closes this on the third line.

Error is:
"Jess reported an error in routine Jesp.parsePattern
while executing (batch rules/ec-1.clp).
Message: No such slot posLshift in template MAIN::mon at token
'posLshift'."
There's a missing close-parenthesis on the first line (three open,
only two close) so Jess thinks you mean to test the contents of the
"tstamp" and "posLshift" slots in a "mon" fact.
The JessDE is pretty good at helping you spot this sort of problem.
Besides formatting your code so that your errors are more obvious,
this kind of error will lead to a train wreck with all sorts of
error markers from this point on in the file, giving you a strong
hint that something is wrong. If you can't use the JessDE, use the
Lisp mode in any programmer's editor -- it will know how to format
Jess code to point out this error.
