The Block Move Byte, Block Move Word, and Block Move Double Word instruc-
tions move an assigned block of data values from a source memory location
(starting address IN and successive addresses) to a new memory location (start-
ing address OUT and successive addresses). Parameter N assigns the number
of bytes, words, or double words to move. The block of data values stored in the
source location are not changed.
N has a range of 1 to 255.
