Thanks Jonathan, this is exactly what I was looking for. I was 
getting confused with not being able to resize because I was 
looking at int[] arrays and I guess the way I was defining them 
caused them both to be dynamic (when I thought one was static).

On a similar not, is there an accepted way to assign across 
arrays? As Steve mentioned, cross-slicing isn't supported, so is 
the best way to iterate through the array and assign as necessary?
Thanks, Jamie
