brain fart defining inputs

in one of the first examples "button" there is below..

int buttonState = 0;         // variable for reading the pushbutton status

  if (buttonState == HIGH) {     

Is there anything wrong with defining and setting it to LOW rather than 0 ? I know a 0 is logic LOW, but I cant remember why we use both here?? Probably need a coffee....... :o

Yes you can use LOW or false as well as 0.

Thanks Mike, I think it might have been better in an early example to stick to either one or the other, I got confused and I am an old timer of 2 months :-)
