This needs a small fix.

Next, the value of 'flag' is checked and if it is 1, nothing happens and nesting level finishes and restarts as 'if' and 'else if' repeated at 100 times, Every time 'else if' reached to 100 times , flag ++ and nesting level finishes.As the result, nesting level never exceed maximum.   

It would probably also be worth investigating whether there are not
better ways of implementing what's done here, e.g. via tables or some
such.
