[jnc] Jan-12-2010: Acrobat DDE reference (which includes tags such as "also supported in Acro Reader" is available at: http://partners.adobe.com/public/developer/en/acrobat/sdk/pdf/iac/IACReference.pdf

One thing that caused delay in me understanding the DDE interface is that after you call the DDE function FileOpen, to work with the document (for instance, calling DocGoTo()) you must call DocOpen(). FileOpen tells Acro Reader to open the document but that does not enable you to then control the document. DocOpen() will make the document then available for DDE control.
