In various aspects, actually. The work that I've done
to this point has mainly been in AppleScript so I'm
just curious as to the range of possibilities in
AppleScript's interactions with Squeak. For instance,
(with either the AppleScript classes in the standard
image or from a third party) can one get back an
AppleScript object which can be stored or manipulated
within Squeak? Like a reference, number, record,
script object (with it's properties intact) ect.? Or
is is one limited to only getting back strings?

So, I assume one is limited to just getting strings?
Then, if needed, one must extract and translate that
data into the appropriate Smalltalk object e.g.- '8'
to 8 or '{"hello", 7, }' to  #('hello' 7 ).

I'm using Mac OS 9.1 so I don't have those XML-RPC or
SOAP components.

Thanks,
