- Yes, that is the essence of the problem - there are CPUs out there
- which have a very small number of CPU registers (perhaps only two
- or three) available to the user. As I recall, the TI 9900 has one
- register which points to a location in memory where the rest of the
- "registers" exist, and of course older HP CPU's have their own ideas
- about where data is stored.
