Is there a possibility to program a kind of "state machine" via functions?
A
Like variables also functions are handled internally as tables. A function thus has a name and a value. This value can be changed during runtime and hence decide which function will be called next.
Example code:
if myfunc then
 myfunc()
else
 -- defining all subfunctions
 function my_state_init_done()
   ..
   myfunc = my_state_1
 end
 function my_state_1()
   ..
   myfunc = my_state_2
 end
 function my_state_2()
   ..
  myfunc = my_state_init_done
 end
 myfunc = my_state_init_done
end
