Registers available in the 6809. Similar in architecture to the 6800, the 809 has three extr
a registers to facilitate memory accesses: a direct page register, a user stack register, and a second index register. The instruction set is also more robust, with the addition of 16-bit add, subtract, and multiply operations.

is
theoretical--and no language better exemplifies this than C++.
