DDE calls using Win32::OLE?

TedPride has asked for the wisdom of the Perl Monks concerning the following question:

It seems that there used to be a module Win32::DDE::Client, but that module is no longer on CPAN or anywhere because DDE has since been replaced by OLE. However, while the Win32::DDE::Client interface was easy to understand:

Request(ITEM)
Returns the value of ITEM from the DDE server. 

Poke (ITEM, VALUE)
Pokes VALUE into ITEM at the DDE server. 

Execute (CMD)
Executes CMD at the DDE server.

I'm having a lot of trouble understanding the Win32::OLE equivalents:

Can someone explain how I do the equivalent of Request, Poke, and Execute using OLE?
