I apologize in advance if this is either a stupid or frequently-asked
question. But I'm stumped.

How does one execute an external MathLink program from Mathematica while
watching it perform in the MS Visual C++ 5.0 debugger?

I read the documentation in the MathLink Developers Kit (for Win NT 4.0 and
Vis C++ 5.0) and tried the command

 LinkOpen["foo", LinkProtocol->"FileMap", LinkMode->Listen]

The problem is that I don't know how to launch the app in the Vis C++ IDE's
debugger, and pass _both_ the arguments to the external procedure _and_ the
switches "-linkname foo -linkprotocol FileMap -linkmode connect" in the
main() arg list. There must be some way to establish a peer-to-peer
connection between Mathematica and the debugger, but I can't figure it out.

If you could shed light on this problem (using, say, the trivial addtwo
example shipped with MathLink), I would be very grateful.
