- Computers that store the registers in memory can do the indexing, including
- the PDP-10 (and 20, but *not* the PDP-11), some Honeywell machines
- (predecessors to the Multics line), and the TI 9900. Some register window
- mechanisms may let you do this (sort of), but most processors do not seem to
- do it in the manner you have described. Some machines could get that effect by
- building and executing an instruction, or having an "execute" instruction.
