Hi Jim,
I suppose you could do a union (yielding a 3rd array) and an intersect
(yielding a 4th array) and then remove the intersect elements from the
union array. It's not what you wanted but it would work. Like so:
put arrayOne into intersectA
intersect intersectA with arrayTwo
put arrayOne into unionA
union unionA with arrayTwo
repeat for each key tKey in intersectA
delete variable unionA[tKey]
end repeat
-- now unionA contains the anti-intersection (?) of the two original arrays

What I need is an array of the elements removed. Intersect leaves everything
but.
Is there an array operation that accomplishes this?
The dimensions of my arrays are very large and so using "is among" on the keys
is not an option.
