DDE was Microsoft's first attempt at "opening Windows applications" to others
by exposing commands to drive these applications.  It is around today for
legacy purposes only, not much is being done with DDE (Dynamic Data Exchange).

The preferred method for interacting with a Windows program from another is via
OLE, which exposes objects, methods and properties for the target application.
OLE objects are becoming COM and DCOM objects, which according to legend <said
with a grin>, will interact with ORBs (DCOM will, that is)

Unfortunately, the HP3000 cannot "see" these objects yet and still must rely on
DDE.

Hopefully, this clears things up just a little.  Not that Neil's wrong - far
from it - it's just that Microsoft's Alphabet soup can be daunting (much like
IBM's :) and that there will come a time, when DDE will become obsolete.
