The interpreter is in the middle of the implementation, there are still a lot of sub commands missing and there is the need for test cases, as I know already about some problems/bugs and there will be a lot of bugs still in there, which have not yet been found because of missing test cases. Right now there has been spent more time to the second topic Tk Widgets in Javascript to be able in the near future to have some demos, which show some of the functionality. There is also the need for more examples/demos.
