Nano

I think we've simplified my question of accessing 3 SRs individually not cascaded. Is it true that if I change the dataPin using I/O ports on the Nano, I then can load a byte on a designated SR? Shiftout(dataPin1, clockPin, MSBFirst, Ledset1); shiftout(dataPin2,.....); shiftout(dataPin3.....); dataPin1=9; dataPin2=10; dataPin3=11; Will this code work? Remember I'm a newbie so I'm not sure if this is legal.
