Here's an example that I have just tried. Althought it was a bit slow on the DDEinitiates in NT4 Workstation.

run /n7 "c:\progra~1\Micros~1\Office\Excel.exe"
lnHandle = ddeinitiate("Excel", "System")
? dderequest( lnHandle, "Topics")
? ddeterminate(lnHandle)
lnHandle = ddeinitiate("Excel", "[Book1]Sheet2")
? ddepoke(lnHandle, "R1C1", "=34*45")
? dderequest(lnHandle, "R1C1")
? ddeterminate(lnHandle)
