To set the current selection of an option control you set its
menuHistory property. But note that setting that property also
trigger's the button's menuPick handler, which can be problematic in
some circumstances.
To counter this, Ken Ray and I have adopted a habit of using a handler
like this one to set an option control's current choice:
on SetOption pBtnName, pNum
lock messages
set the menuHistory of btn pBtnName to pNum
unlock messages
end SetOption
It would be ideal if the language provided a native command for this,
but tucking this into your standard library at least gets the job down
for now.
