     I'm currently trying to write a user interface for a LISP system using
sunview.  Does anyone out there have any experience in doing this and can offer 
any advice?

    It seems that passing arguements back and forth between a C 
process and the LISP process is done on the return of a function.  If so, the 
sunview window, in order to return an input, would have to die or use
a global variable that the LISP process can poll and determine any change
of state.  Neither solution is particularly appealing.  As they say on the
network, Thanks in advance.
