I assume it's called "NIP" as in "nip it in the bud," but I picture a bunch of guys sitting around the table saying, "SWAPDROP is too long. What else could we call it? How about NIP?"

I've dabbled a little with SRPL. I'm always amazed at how specific the commands are: DUP4UNROLL, OVERLEN$, POSCHRREV. I half expected there to be a command called MAXDISTCHAR$.

I also used list processing on my first attempt so that I could use REVLIST.

It's funny how the brain works. When I got it down to 138 bytes, I was convinced I had done the very best I could. Then I saw something that I could do to reduce it further, and further, and further, each time fully convinced that I was absolutely done. Optimizing is a very psychological process.
