Sikkandar,
regard a rule-semaphore as a "guard": It's a variable which you use
on left hand side of rules:
rule 1
when Guard g
<other conditions>
then
<RHS>
end
You can set the semaphore in any other rule to control which other
rules you want to disable or enable...
(If you need background on semaphores, have a look in Operating-
Systems literature)
regards,
Gernot
