 elements in the array represent the frequency distribution of the possible

+By default, RESULTARRAY will be allocated 256 elements if IVARB is a byte array, or 4096 elements

+Any IVARB values less than 0 will be counted in the 0 element of RESULTARRAY, and IVARB values greater than the length of RESULTARRY will be counted in the last element of RESULTARRAY.
