Indirectly addressed DM word is non-existent. (Content of *DM word is
ER:
not BCD, or the DM area boundary has been exceeded.)
EQ: ON when all zeros are transferred to D.
The following example shows @MVN(22) being used to copy the complement of
#F8C5 to DM 0010 when IR 00001 goes from OFF to ON.
#F8C5 1 1 1 1 1 0 0 0 1 1
DM 0010 0 0 0 0 0 1 1 1 0 0

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.
