That's a genuine possiblility on at least one machine. The TI980 has (I would say "had", but I know of at least one that is still operating) 8 16-bit registers that are accessible by a whole range of register-to-register instructions such as RMO (register move), RIN (register increment), RAD (register add), ROR (register or), etc. Register number 7 is the program counter. Ponder the results of: RDE 7,7 decrement the program counter by one. Hint: this is a one-word instruction. The TI980 is word-addressable, not byte-addressable. -- Dave Seaman ..!pur-ee!pucc-i:ags "Against people who give vent to their loquacity by extraneous bombastic circumlocution."
