Is there a clause or macro within loop to cause execution to continue
at the next iteration? If not, is adding a label at the start of the
loop-body and "go"ing there guaranteed to work--or might that not properly
execute the loop stepping code (which would mean that I need to instead
go to the bottom of the loop).
I've looked back and forth through chapter 26 of CLtL II, and once though
I'd seen it, but haven't seen it since.
Thanks

I don't think so. There's a macro to terminate the entire loop,
LOOP-FINISH.

It's not going to work at all, since you can't put GO tags in loop bodies.
Symbols are treated as LOOP keywords, not tags.

Gee, I could've sworn there was a LOOP-CONTINUE macro in some LOOP
dialect; but I can't find it in any I have references on. Perhaps I
dreamt it. I can't think of a case where I couldn't get by without it,
but there are certainly times I wished I had it!

Me, too. But I looked in the dpANS, and couldn't find it.
