Yes, thank you for the reminder. If I'm not completely out in the blue, 
it seems as if the lines in the file produced by the above command are 
aligned on 2-byte boundaries, while in other cases they are aligned on 
4-byte boundaries. Why this discrepance? And is there a way to find out 
what alignment the incoming data uses?
