The first one is going to be given some force and the second one will fall off the table. for instant: So, I should have 16 results. The "Range" variable i use for further processing (function parameter) within the for loop. If he wants to iterate over each dimension, he'll have to do something similar to this. THe outer loop iterates over the dimension, the inner loop over the size of that dimension. So if your array has more then a total of 2^32 elements in it, the linear index will fail.
