In order to perform an OR on 64 bits stored in an array, could you do
something like this:

a = [0,0,0,1,0,1,0,1,1]
b = total(a) GT 0

Then, if any of the elements of a are non-zero, b will be TRUE, or 1.
At least I hope that's what you meant by OR.

Likewise AND would be

c = total(a) EQ n_elements(a)
