I can see only one solution (besides hacking Jess itself). It would require
that the right hand sides of all rules would have to be written as an if
statement, with the condition testing some global variable ?*fire*. To
update the rules, stop the engine, remove all rules, set ?*fire* to false,
batch the clp's, call (run), set ?*fire* to true and rununtilhalt() again. -
Clumsy, but how else?
