The value is binary. The different bits in the binary number mean different things. The # things are system constants. They're pretty much just variables. The first bit is visibility, and can be represented with 1 or #SPSHOW. The one that horizontally flips it is 8 and has a system constant of #SPREVH. You'd want (#SPREVH OR #SPSHOW). If you want to do it in decimal, that would be 9.
