I think i remember microsoft saying they would not support it anymore,
after win95, but it is still used in such applications as the clipboard, Word,
Internet Explorer, etc. in win98, etc.. DR DOS has a similar msg handler
for applications to talk to each otherr.

As for an url, i don't know.... Try a word search for "DDEML" , and look in
the help files in Delphi and Pascal. Oddly, the DDE in turbo pascal v7 in
win3.11 will not work in win95. Naturally, the DDE explainations in mirc are
quite an overview, with no details. I have not upgraded mirc in several
version releases, and i hear OLE and such is now supported in mirc.

Something else i noted, in mirc, if a dde message is sent to a DDE handle
that doesn't exist, *if* windoze is sending back an error, and it should be,
mirc discards it. If nothing else, this makes it easy to write an application
that can function without blowing up or tossing error messages when the
dde extension to it is missing. Since this can be a problem in my code, to
have a big hunk of it, an entire thread, missing, i do implement
handshaking and timeouts.
