Masked Move (MVM)
The MVM instruction is a word instruction that moves data from a source location
to a destination, and allows portions of the destination data to be masked by a
separate word. As long as the rung remains true, the instruction moves the data each
scan.

•
Source is the address of the data you want to move.
