That may be, but just because the underlying mechanism is still
in use may not be reason to say the beast called DDE that is built
on top of it is still a recommended approach.

My attempts to use it were with LabVIEW, and involved attempting
to copy "large" blobs of binary data around between LabVIEW and
a separate C program.  Mostly I recall discovering it could not
handle binary data fully (maybe no 0 bytes?) or could not handle
more than 65280 bytes at a time, or something ugly like that.

Thanks, I should check that out.
