Henrik,
Yes, I mistakingly was thinking that some 'W=' takes the two consecutive bytes. Also array[0] and [1] confuses me at times with for-next etc. so I just consider array start at [1].
What you coded is good. The top and bottom (out[0] and out[3]) are simple but the ones where the 6 bit straddle 2 bytes take a little more. I tried to follow your calc on out[2] but my brain started smoking. Just wondering if '+' changes the value as opposed to the '>>' and '<<' and &. But, if it works, never argue with success.
Anyway, thats all a relatively small simple code.
