hi all,

   could anybody explain to me how the statement,

 (" ");
   
    could result in a successful compilation. This works inside any function.
-------------------------------------------------------------------------------------
   The following :

( );

yields an error. Similarly,

--------------------------------------------------------------------------------------
" " ;

    also works fine. I am using PB4.2 .
