Functions TO
Writes the data of "n3" points, which begin with the device specified at (S), to the
addresses starting at the address specified at "n2" of buffer memory inside the
special function module specified at "n1".
When a constant is designated to (S), writes the same data (value designated to (S))
to the area of n3 points starting from the specified buffer memory.
((S) can be designated in the following range: -32768 to 32767 or 0
