You can write your own string analysis function to implement past().
As I understand what you want, the following would work:
procedure past(s)
suspend (tab(find(s)),match(s))
end
I'm not convinced you really want a co-expression in your 2nd question, but
need to think about that some. No doubt someone else will have a good
solution soon!
