Value of
Order
In (array or not) Storage method in AryOut[]
_LOW_HIGH
Not an array Value of In is stored in AryOut[0].
Array Value of In[i] is stored in AryOut[i].
_HIGH_LOW
Not an array Value of In is stored in AryOut[1].
16#00 is stored in AryOut[0].
Array In[i] (where i is even) is stored in AryOut[i+1].
In[i] (where i is odd) is stored in AryOut[i−1].
If the number of elements in In[] is odd, 16#00 is stored last in AryOut[n−1].
