I am interested in how Hypercard can be used with programs written in C.
Is there a way to allow HyperTalk programs to invoke functions in an
external C program and rapidly pass data between a HyperTalk program and
a C program?  I am interested in whether HyperTalk can be used to create
a user interface for an existing application.  The users could then
modify this user interface without being give source code to the main 
part of the application.  Is this feasible?  I've checked through the
documentation that comes with HyperCard and a third-party reference
book, but I haven't seen anything that looks like what I want.  Any
suggestions would be welcomed.

Thanks.
