Thank you for explaining what you think the OP meant. In that case, my
reply (#4 in this thread), also given later by
ks_isaf@126.com, would have been adequate.

Since the OP seemed to be less experienced in Lua than the galaxy of
grandmasters posturing on this list, I assumed that a little
explanation of coroutines was in order.

Of all Lua's features, the coroutine library  took me longest to
understand.  I enjoyed writing in simplest possible terms about them,
and found thinking about "extra arguments passed to coroutine.resume"
as messages helpful.
