Hey thanks, I'm glad I started this discussion because I've been thinking about it for a long time and now I have a lot of solid information to help me get started on a project. It will be done slowly in my scarce spare time I'd like to create a native compiler for JavaScript. First, I know converting to MSIL or bytecode is the much easier way to go and with all this info iam well on my way. Thanks again and thanks to everyone who responded.:thumbsup::thumbsup:
