I have found the method for addressing the sheet name and the cell ranges directly through DDERequest or DDEPoke.
Define destinationfile, nameofthesheet (it can contain spaces) and datatobeaddedseparetedbytabs as you wish...
Define the range of cells:
R2C1:R100C20 (you can use %variables% in place of the numbers)
then use the DDE commands:
DDEPoke>Excel,%destinationfile%:%nameofthesheet%,%XLRange%,%datatobeaddedseparatedbytabs%
Hope it is useful...
