/* Harbour Sample Function */
Function Main()
...
oWnd:bCommNotify = { | pParam, nValue | EventNotify( pParam, nValue ) }
oThread := ThreadOn( 10, 20, oWnd:hWnd ) // Input Parameter 10, 20, oWnd:hWnd
Return nil
Function EventNotify( pParam, nValue )
MsgInfo( GetWaitData( pParam ) ) // Return Value 2
Return nil
