Both S and D may be in the same data area, but their respective block areas
must not overlap. S and S+N must be in the same data area, as must D and
D+N.
When the execution condition is OFF, XFER(70) is not executed. When the
execution condition is ON, XFER(70) copies the contents of S, S+1, ..., S+N
to D, D+1, ..., D+N.
