So, any suggestions for the best way of getting around these limitations (I
mean, without having to buy a 64-bit machine) -- how about chopping the
array up into smaller blocks and performing for-next loops -- processing
part of the array, writing the results, and then processing the next part?
Are there better ways than this?
