The Block Move function moves the N number of words
specified by the address IN to the address OUT. N has a
ENO
range of 1 to 255.
The input and output data types can vary, but must be of
OUT
the same type.
Block Move is a non-standard IEC-only function.
Error conditions that set ENO = 0: SM4.3 (run-time),
0006 (indirect address), 0091 (operand out of range)
