This is not an FB^3 point, and has come up in the FBII list before. putting '%' after a constant makes it 'set' that bit, so _boldBit can equal = 0 and _boldBit% will thus equal 1, as any bit0 of the byte will be switched on. in the same way that if you have: _myConstant = 2 _myConstant% will give you a value of 8 as the 3rd bit will be set. Hope that this is clear jonathan
