Operation:
Source data is provided by a combination of operands
S and n. Where S specifies the head address of the
data and n, the number of consecutive bits. The
source data is read as a single number (binary to
decimal conversion) Q. The source number Q is the
location of a bit within the destination device (D) which
will be turned ON (see example opposite). When the
destination device is a data device n must be within
the range 1 to 4 as there are only 16 available
destination bits in a single data word. All unused data
bits within the word are set to 0.
