applescript studio in xcode and before I upgrade it and add new
features, I am wondering whether you all think objective-c is a more

Hey all,
I'm just starting to learn Objective-C and then later Cocoa. I've started
with Objective-C just to learn exactly how the object oriented features

I'm writing a library that needs to be called from interpreted

to programmatically and manually interact with them.  Since the library
is being called from an interactive session it's unacceptable to just
