First of all, thanks for replying. 

start:
  exactf "f", find_o
  advance
  goto start

find_o:
  exactf "o"

  exactf "bar", done
  goto find_o

done:
  end

How does that deal with being matched against, say, "afafoobarz"? Perhaps: 
start:
  save
  exactf "f", find_o
  restore    #to keep the balance
  advance
  goto start

find_o:
  exactf "o", find_bar
  restore
  advance
  goto start

find_bar:
  exactf "bar", done
  goto find_o
...

would be more correct? Actually, come to think of it, I don't see how it deals with a case like "babylon" (it doesn't match at all) either--maybe advance should have a parameter that it jumps to if it fails?
