A.2.10 MOVE
The MOVE command copies the block of memory starting at the source address
to a block beginning at the destination address. Typically, this command has
an /N qualifier so that more than one datum is transferred. The destination
correctly reflects the contents of the source, regardless of the overlap between
the source and the data.
The MOVE command actually performs byte, word, longword, and quadword
reads and writes as needed in the process of moving the data. Moves are
supported only for the physical and virtual address spaces.
