oWin:command( <nWParam>, <nLParam> ) -> NIL

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

 PARAMETER:

  <nWParam>    This parameter holds two Words which have the following 
               meaning:

               <nCode>  If the message is from a control, the value 
                        ( retreived by nHiWord( nWParam)) specifies the 
                        notification code. If the message is from an 
                        accelerator, the value is 1, if the message is 
                        from a menu, it is 0
  
               <nID>    This part ( retrieved with nLoWord(wParam) )
                        represents the identifier of either an item, a
                        control or an accelerator.

  <nLParam>    If the message has been dispatched by a control, this 
               parameter contains the handle of that control. Otherwise this
               parameter is NULL.


 DESCRIPTION:

  The WM_COMMAND message is sent to a window when the user selects 
  an item from a menu, when a control sends a notification message to its 
  parent window, or when an accelerator keystroke is translated. This
  Method launches the appropriate Actions
