     If I call OpenDeskAcc('Hypercard') from my MacApp program,
Hypercard comes to the front of the screen.  I can then simulate
a pipe by using resources in a shared file; an idle script in
my HC stack takes care of checking for new messages from the co-
application.  It's not pretty, BUT IT WORKS!
     (I use an XCMD to return control from Hypercard.)
