Hi Alex,

> Actually, the 'set>' and 'val>' methods are also not needed.

I am not sure about that, because if you use +Radio inside a chart,
the selected value will be repeated as many times as there are
radiobuttons in a group.  Keeping the val NIL for all except the first
radio button avoids this.

This is how I use it:

     (<p> NIL ,"Enrolment form:"
        (let Fname (blob (; *ID eve) 'ftem)
           (when (info Fname)
              (in Fname
                 (gui '(+E/R +Fmt +Chart)
                    '(fdat : home obj)
                    '((Fdat)
                      (let FvarM (in (blob (; *ID eve) 'ftem) (markupVars T))
                         (fdat2chart Fdat FvarM)))
                    '((Lst)
                      (let FvarM (in (blob (; *ID eve) 'ftem) (markupVars T))
                         (chart2fdat Lst FvarM)))
                    1)
                 (<div> "enrform"
                    (htMarkup NIL (; *ID fdat)))))))

htMarkup actually creates the gui components, e.g. (gui 1 '(+Radio) N V).

Cheers,

Tomas
