Description:

MOVS destination-string, source-string

MOYS (Move String) transfers a byte or a word from the source string (addressed by SI) to the destination string (addressed by DI) and updates SI and DI to point to the next string element. When used in conjunction with REP, MOYS performs a memory-to-memory block transfer.

if w = 0 then SRC = (SI), DEST = AL, DELTA = 1 else SRC = (SI) + 1:(SI), DEST = AX, DELTA = 2
