Not sure what you're trying to achieve. AFAIK you can't directly store an object (or even just an object reference) in a cursor. But if you want to do what you're saying in the first line you could do something like this:

CREATE CURSOR ValsCursor ( FSName C( 16 ), PropName C( 16 ), PropType C( 1 ), CharVal C( 100 ), IntVal I, NumVal N( 8, 2 ), LogVal L )

INSERT INTO ValsCursor
  ( FSName ;
  , PropName ;
  , PropType ;
  , CharVal ) ;
  VALUES ;
    ( "MyFormSet" ;
    , "Name" ;
    , "C" ;
    , MyFormSet.Name )

INSERT INTO ValsCursor
  ( FSName ;
  , PropName ;
  , PropType ;
  , IntVal ) ;
  VALUES ;
    ( "MyFormSet" ;
    , "FormCount" ;
    , "I" ;
    , MyFormSet.FormCount )

INSERT INTO ValsCursor
  ( FSName ;
  , PropName ;
  , PropType ;
  , LogVal ) ;
  VALUES ;
    ( "MyFormSet" ;
    , "AutoRelease" ;
    , "L" ;
    , MyFormSet.AutoRelease )
