controlling lua from a c program

[Håkon Evensen <haakon.evensen@...>]

Hi

I have a couple of questions i cant find any answers for in the manual..

Is it possible to load a "script" into the lua state and do one execution 
of a instruction/line/whatever at a time.  Lets say i have a lua script 
going in infinite loop, and i want to check for another state in the host C 
program for breaking the lua execution.   I want to execute a script but i 
dont want to leave the entire control of the host thread in the hands of 
the script.   is it possible to set a line hook and break further execution 
from there?

I want to control the reading/writing of variables.  I could do this by 
reading the lua variables, but how do i know where and when they are 
altered? I could use a linehook and sniff all of the variables at this 
point but isnt it possible to hook/break on variable write/reads?
