[IronPython] Need a Good Embedded Example

[Joshua J. Pearce]

Joesox,

Thank you very much! Now, what if I the getcount() method was actually
getcount(string arg1), is there a way to call it from within the IP script?
Or do I need to parse the IP script ahead of time, and call the function
myself? That would be like writing my own scripting language, so I hope
there is a way to call the method from within IP scripts.

Many thanks!
