Using X and Y as Pointers

To initialize pointer use

        ldx      #table

not

        ldx      table

For example

        ldx      #table    ;  Address of table => X
        ldx      table     ;  First two bytes of table => X

To step through table, need to increment pointer after use

        ldaa     0,x
        inx

        ldaa     1,x+
