DB Apps and Net DDE ... please help

Hi...I need individual db apps running on several computers across a
Win95 network to be able to exchange simple text messages.
 How do I use Net DDE to get one app to be able to broadcast a string
message to all other instances of the app running on other machines.
Any code snippets would be greatly appreciated...and I would be grateful
if any responses could be e-mailed to me at use...@nbnet.nb.ca.
