MOVEM is definitely not "nasty". It is a perfectly legitimate technique and can shave many cycles off if you move a large block of memory. For the instance you cited in the last message (move (ax),(ax)+), ie. moving from a fixed single location to a block of addresses, this is indeed the fastest way I know of. Of course I had to convince myself that it was by attempting to use shifts and such to "fill up" a register before storing it.
