When the execution condition is OFF, XFER(040) is not executed. When the ex-
ecution condition is ON, XFER(040) copies the contents of S, S+1, ..., S+N to D,
D+1, ..., D+N.
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.
N must be BCD.
Note 1. Transfer source and destination words can overlap, so XFER(040) can be
used for word shift operations.
2. Refer to page 101 for general precautions on operand data areas.
ER (A50003): N is not BCD.
Content of *DM word is not BCD when set for BCD.
When CIO 000000 is ON in the following example, the contents of CIO 0001
through CIO 0003 are copied into D00010 through D00012, as specified by the
first operand (#0003).
