oWin:DDeExecute( <hWndSender>, <nCommand> ) -> nil

------------------------------------------------------------------------------

 PARAMETER:

  <hWndSender> Is the handle of the DDE client window that sends the command

  <nCommand>   Is the handle to a GLOBAL ATOM with the Command string.
               Can be retrieved via DDeGetCommand( nCommand )


 DESCRIPTION:

 Whenever the DDE server window receives a DDE command from a client, the
 eventhandler calls this method with information about the application that
 requested the command and the actual command. If the iVar bDDeExecute
 contains a block, then this block is evaluated with both parameters as
 arguments.
