In the following example, the 10 word range from DM 0010 to DM 0019 is
searched for addresses that contain the same data as DM 0000 (#FFFF). Since
DM 0012 contains the same data, the EQ Flag (SR 25506) is turned ON and
#0012 is written to DM 0001.

N must be BCD between 0001 and 3000.
S must be BCD between 7000 and 9999.
S and S+N–1 must be in the same data area, as must D and D+N–1.
When the execution condition is OFF, XDMR(––) is not executed. When the exe-
cution condition is ON, XDMR(––) copies the contents of expansion DM words S
through S+N–1 to the destination words D through D+N–1.
The Expansion DM area must be set in the PC Setup before it can be used in
programming. Do not exceed the set range of the Expansion DM area.
Execution of XDMR(––) is given priority whenever a power interruption occurs.
ER: The specified expansion DM words are non-existent. Make sure that
the specified words have been allocated to expansion DM. Refer to
7-1-15 UM Area Allocation for details.
Indirectly addressed DM word is non-existent. (Content of *DM word is
not BCD, or the DM area boundary has been exceeded.)
