I need an embedded script language in a large VC++/MFC
application, so users can control the app by writing
in script.  How do I set up the linkage for C++ to pass
parameters to JavaScript and for Javascript to pass
parameters to the C++ routines it calls?

Is javascript the language of choice? It may be a good choice if the application you are writing is a browser since Javascript functions are highly specific to this environment but I have doubts that it is useful as a general purpose language.

Java might be a better language (although it is not really a script language).

My personal choice would be perl which now has a number of options including being compiled, having links to C++ and being able to call it from perl.

Although I agree with icd, as a possible answer to your question you could use a combination of applets using JNI and the Live Connect type communication between JS and applets. (This type of communication is available in both MSIE and Netscape, and I belive under Hot Java as well).

Would you be intrested in a more detailed explanation?

For an application dependent on VC++/MFC, the language of chice would be some version of Visual Basic; alternatively look at IBM's REXX.

If you're not allergic to Microsoft, there is a smooth commercial solution called ActiveX Scripting; check out
