   Not quite. There's only one special "segment", the "zero page".   
   It can be accessed using an implicit segment 0, that is, address bits   
   15 through 8 are all zeroes.   
   OTOH, if you use the indirect-Y addressing mode, you're almost   
   using a GDT. That is, the zero page can contain up to 128 16-bit   
   addresses and you can choose one of them and add an 8-bit   
   offset to those 16 bits.
