(34S) Prime Factors

[Dave Britten]

Alright, the included PF is just using the NEXTP approach with a simple square-root bailout, so it's about as slow to reach the second factor as when I attempted it with NEXTP. It's using a few BACKs/SKIPs to optimize branching, but I don't think that buys it much. It IS only 29 steps, though, so it's pretty space-efficient.

So whoever maintains the iOS version of the emulator, if you're reading this, feel free to replace PF with FAC. Not only is it faster, it's also a nice demo of KEY? to browse stored data.

I think next I'll experiment with using LocR-> to dynamically allocate local regs to avoid overwriting globals. That'll make the factor browser more complicated, since it won't be starting at reg 01, though (but that's assuming redefining LocR even works in the first place).
