Thanks Mike,
Very good idea.  
I was also giving some thought to writing a pre-program to read the
data and  optimise the array 1's prior to entering them into the array
and then resorting to shuffling the elements around.
I will have to give it a lot more thought as it is at the moment
beyond my limited coding knowledge.
