Well, this is an first draft of the script:

-- @param q Npc line number

local dialog = {}

if (q=="root") then
        --we insert all answers
        table.insert(dialog,{"Yes sir, Im ready!","yes"})
        table.insert(dialog,{"I really dont like you giving me
orders","no"})
        table.insert(dialog,{"I wouldnt call it a skirmish. Was a really
bloodbath if you ask me.","middle"})
        --this is the npc line
        line="You are one of those rookies that survived yesterday's
skirmish. I have a mission for you, are you ready for more action?"
        count=3 -- how many choices we have
        return line, count, ta

    elseif (q=="no") then
         line="I really wasn't asking you. Go see the smith and get a
decent armor and sword. Then come back to me"

         end

(it is unfineshed of course).
Basically, what I dont know now is how to get the table in the host app.
I have checked get_table documentation but cant clearly underestand how
to read all those values.
