S and S+N must be in the same data area, as must D and D+N.
DM 6144 to DM 6655 cannot be used for D.
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.
ER: N is not BCD.
S and S+N or D and D+N are not in the same data area.
Indirectly addressed EM/DM word is non-existent.
(Content of *EM/*DM word is not BCD, or the EM/DM area boundary
has been exceeded.)
