Ron, if your global is set before ***asserting facts**** to the working memory and not changed anymore, you can use it.
   Also, make sure your array or whatever is an attribute of a class, and so has some semantic to it.

   You can do things like this:

when
    MyArrayContainer( $flags : flags )
    Number( intValue >= SOME_GLOBAL_THRESHOLD ) from
          accumulate( $f : Flag( value == SOME_GLOBAL_VALUE ) from $flags,
                             count( $f ) )
then
   // threshold met
end

    Another options is just create a holder class for your globals and assert it as a fact instead of using globals:

when
    MyParameters( $threshold : threshold, $value : value )
    MyArrayContainer( $flags : flags )
    Number( intValue >= $threshold ) from
          accumulate( $f : Flag( value == $flags ) from $flags,
                             count( $f ) )
then
   // threshold met
end
 

    Hope it helps,
       Edson
