Hi,

I was reading about while and until in the new Springer book and it said
that "these loops will work at i-time and perf-time if the condition is
i-time". I'm wondering how can we prove that statement. My reasoning is
that all the perf-code inside a loop would never get executed because in
order to go from init-time to perf-time with Csound, the i-time loop
itself must have already ended. Otherwise we'll still be at
initialization time. Does this make sense to you?

Cheers.

No. If the loop was only i-time only, it would only repeat at i-time. At perf time it would be ignored.

So, a reminder for the second edition maybe? Is there an address where
the erratas are listed? (The book is great!)

yep, it was a slip. The i- condition makes it an i-time loop, and a k- condition makes it a
perf-time loop. I’ve added it to the errata, thanks for pointing it out.
