You could think of it as a not bad use of the design principle "Clear The Simple Stuff Out Of The Way First". Destinations are commonly a lot simpler than sources
That's not usually true in assembly languages, though, where the source and destination are both very restricted and often about the same complexity. That's not to say that right-to-left is the wrong way to do it in an assembly language, but there are less misleading words than "move" that could be used. Z80 assembly language uses "load", which makes things considerably clearer: LD A, B ; load A with B -- Greg -- http://mail.python.org/mailman/listinfo/python-list
