[rules-users] Define global variables at the top of a rules file

[Martin A]

Hello,

Thanks for your response!

But I don't understand why such a rule with a high salience which looks
like:

global int VARIABLE;

rule "init"
  salience 999;
  when
    (eval(true))
  then
    VARIABLE = 1;
end

would fire only once?

Thank you,
Martin
