I have a contractor rewriting some code that ultimately generates reports in
an Excel spreadsheet. The old process was that our data crunching software
would spit out data, then we'd run a VBA macro to pull it into the
spreadsheet and do all the formatting.

However, on the rewrite, I notice that he's using dde in the new data
crunching software to generate the spreadsheet. I guess I was under the
impression that dde is rather old and obsolete. Is that correct and does
anyone have any knowledge of its future support in Excel?
Thanks
