[Tutor] CBNC control loop.

# I guess I just needed a nap...
for n in range(len(seqlist)):
     idxpos = seqlist[n]
     idxlist.append(idxpos)
         while idxpos+len(seqlist)<= len(message):
              idxpos = idxpos+len(seqlist)
              idxlist.append(idxpos)

I'll probably be back later to ask if there's a better way
to do what I'm doing (and to explain what I'm doing).
